+# Publishing SkillOpt-Sleep — how people install and use it
+
+This is the open-source SkillOpt-Sleep tool: a nightly offline "sleep cycle" for
+local coding agents, shipped as plugins for **Claude Code**, **Codex**, and
+**Copilot**. One engine ([`skillopt_sleep/`](skillopt_sleep)), three thin shells
+([`plugins/`](plugins)), decoupled from the research code.
+
+## How end users install it
+
+### Claude Code
+
+The Claude Code plugin ships a marketplace manifest at
+`plugins/claude-code/.claude-plugin/marketplace.json`.
+
+```text
+# inside Claude Code:
+/plugin marketplace add microsoft/SkillOpt
+/plugin install skillopt-sleep
+/sleep status
+```
+
+(`/plugin marketplace add <owner>/<repo>` reads the marketplace manifest from the
+repo; the entry points at `plugins/claude-code`.)
+
+### Codex
+
+```bash
+git clone https://github.com/microsoft/SkillOpt.git
+cd SkillOpt
+bash plugins/codex/install.sh           # installs /sleep prompt + skill
+export SKILLOPT_SLEEP_REPO="$(pwd)"      # so the runner is found anywhere
+# then, in Codex:  /sleep status
+```
+
+### Copilot
+
+```bash
+git clone https://github.com/microsoft/SkillOpt.git
+# register the MCP server with your Copilot config (see plugins/copilot/README.md
+# and plugins/copilot/mcp-config.example.json), pointing SKILLOPT_SLEEP_REPO at
+# the clone. Then ask Copilot to "run the sleep cycle".
+```
+
+Requirements for all three: Python ≥ 3.10, and the corresponding agent CLI on
+PATH. The default backend is `mock` (no API spend); `--backend claude|codex`
+uses the user's own budget.
+
+## Wider distribution (optional, maintainer steps)
+
+1. **GitHub Release.** Tag the milestone so users can pin a version:
+   ```bash
+   gh release create sleep-v0.1.0 --title "SkillOpt-Sleep v0.1.0" \
+     --notes "Nightly offline self-evolution plugins for Claude Code, Codex, Copilot."
+   ```
+
+2. **Official Claude Code plugin marketplace.** To appear in the public
+   directory, open a PR adding a `marketplace.json` entry to
+   [`anthropics/claude-code` / the official marketplace repo], pointing at
+   `microsoft/SkillOpt` subdir `plugins/claude-code`. Users could then
+   `/plugin install skillopt-sleep@<official-marketplace>`.
+
+3. **PyPI (optional).** `skillopt_sleep` is a standalone package
+   (`pyproject.toml` lists it). A `pip install skillopt-sleep` distribution would
+   let users run `python -m skillopt_sleep ...` without cloning. Build with
+   `python -m build` and publish with `twine`.
+
+4. **README News.** The main [`README.md`](README.md) already announces the
+   release and links to [`plugins/`](plugins) and
+   [`docs/sleep/FINAL_REPORT.md`](docs/sleep/FINAL_REPORT.md).
+
+## Verifying a release works
+
+```bash
+# deterministic, no API key:
+python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves
+# the unit suite:
+python -m unittest tests.test_sleep_engine
+# the MCP server (Copilot):
+printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
+  | SKILLOPT_SLEEP_REPO="$(pwd)" python3 plugins/copilot/mcp_server.py

-# ReflACT: Reflective Agent Tuning
+# SkillOpt: Executive Strategy for Self-Evolving Agent Skills
 
-ReflACT is a framework for optimizing an external skill document through iterative rollout, reflection, editing, and gated validation.
+*Train agent skills like you train neural networks — with epochs, (mini-)batchsize, learning rates, and validation gates — but without touching model weights.*
 
-It does **not** fine-tune model weights. Instead, it treats the skill document as the optimization target:

-## Method Overview
+## News 🔥🔥🔥
+- **[2026-06-08]** 😴 **SkillOpt-Sleep is here — plugins for Claude Code, Codex, and Copilot.** Give your local coding agent a nightly *sleep cycle*: it reviews your past sessions offline, replays your recurring tasks, and consolidates validated long-term memory + skills behind a held-out gate, so it gets better the more you use it. Validated on the public [gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1` benchmark with **real Claude and Codex** (deficient skills 0.00 → 1.00 on held-out, all 4 seeds). It's an **open-source tool decoupled from the paper code**. See [`plugins/`](plugins/) and the [SkillOpt-Sleep section](#-skillopt-sleep--the-deployment-time-companion) below.
+- **[2026-06-03]** 🎉 **[gbrain](https://github.com/garrytan/gbrain), [gbrain-evals](https://github.com/garrytan/gbrain-evals/blob/main/docs/benchmarks/2026-06-03-skillopt.md), and [darwin-skill](https://github.com/alchaincyf/darwin-skill) have all integrated SkillOpt.**
+- **[2026-06-02]** 🎉 **SkillOpt [v0.1.0](https://github.com/microsoft/SkillOpt/releases/tag/v0.1.0) is now available on [PyPI](https://pypi.org/project/skillopt/)!** Install with `pip install skillopt`. This initial release includes the full training loop (rollout → reflect → aggregate → select → update → evaluate), multi-backend support (OpenAI / Azure / Claude / Qwen / MiniMax), six built-in benchmarks, and WebUI dashboard.
 
-### Optimization Target
+---
 
-Each run maintains a mutable markdown skill document. The framework repeatedly improves that document instead of changing model parameters.
+## Overview
 
-This gives a training-style loop for prompt / policy optimization:
+Modern agent skills are usually hand-crafted, generated one-shot by a strong
+LLM, or evolved through loosely controlled self-revision — none of which
+behaves like a deep-learning optimizer for the skill itself, and none of
+which reliably improves over its starting point under feedback.
 
-1. Roll out the current skill on a batch of tasks.
-2. Reflect on failures and successes.
-3. Merge patch proposals into a coherent candidate update.
-4. Rank and select a bounded number of edits.
-5. Apply those edits to produce a candidate skill.
-6. Validate the candidate skill on a held-out selection split.
-7. Keep the update only if the gate accepts it.
+**SkillOpt treats the skill document as the trainable state of a frozen
+agent**, and trains it with the discipline that makes weight-space
+optimization reproducible. A separate optimizer model turns scored rollouts
+into bounded add / delete / replace edits on a single skill document; a
+candidate edit is accepted only when it strictly improves a held-out
+validation score. A textual learning-rate budget, a rejected-edit buffer,
+and an epoch-wise slow / meta update make skill training stable while
+adding **zero inference-time model calls** at deployment.
 
-### Per-Step Pipeline
+The deployed artifact is a compact `best_skill.md` (typically 300–2,000
+tokens) that runs against the unchanged target model. Across **six
+benchmarks, seven target models, and three execution harnesses** (direct
+chat, Codex CLI, Claude Code CLI), SkillOpt is best or tied-best on **all
+52 evaluated (model, benchmark, harness) cells** and on GPT-5.5 lifts the
+average no-skill accuracy by **+23.5 points in direct chat, +24.8 inside
+the Codex agentic loop, and +19.1 inside Claude Code**. Optimized skill
+artifacts transfer across model scales, between Codex and Claude Code
+harnesses, and to nearby benchmarks without further optimization.
 
-Every training step executes the following pipeline in `reflact/engine/trainer.py`:
+For the full method, ablations, and per-cell results see the [paper](https://arxiv.org/abs/2605.23904); for a visual walkthrough of the loop see the [project page](https://microsoft.github.io/SkillOpt/); for deeper API / backend / benchmark docs see [`docs/`](docs/).
 
-1. **Rollout**
-   The student model runs a batch of tasks using the current skill.
+## 🎬 Demo Video
 
-2. **Reflect**
-   The teacher analyzes minibatches of trajectories and emits raw patches.
-   Failure-driven and success-driven patches are tracked separately.
+https://github.com/user-attachments/assets/eb12d3bc-371c-467f-904d-91b61f339ed7
 
-3. **Aggregate**
-   Raw patches are merged hierarchically. Metadata such as `support_count` and `source_type` is carried into the merged patch so later ranking can use it.
+<p align="center">
+  <a href="https://youtu.be/JUBMDTCiM0M"><b>▶ Watch the full demo on YouTube</b></a>
+</p>
 
-4. **Select**
-   The teacher ranks the merged edit pool and keeps up to `edit_budget` edits.
+---
 
-5. **Update**
-   The selected edits are applied to the skill document. The framework records an `edit_apply_report.json` so you can see which edits actually landed, which were skipped, and why.
+## 😴 SkillOpt-Sleep — the deployment-time companion
 
-6. **Evaluate / Gate**
-   The candidate skill is evaluated on the selection split. Gate validation is mandatory in this branch. A candidate update is accepted only if it improves over the current selection score; a new global best is tracked separately.
+SkillOpt (above) trains a skill offline on a benchmark. **SkillOpt-Sleep**
+applies the same discipline to *your own daily usage*: it gives a local coding
+agent a nightly **sleep cycle** that reviews your past sessions, replays your
+recurring tasks on your own API budget, and consolidates what it learns into
+**validated** long-term memory and skills — behind a held-out gate, staged for
+your review. The agent gets better the more you use it, with no weight training.
 
-### Within-Epoch Memory
+It synthesizes **SkillOpt** (validation-gated bounded text edits), **Claude
+Dreams** (offline consolidation; review-then-adopt), and the **agent sleep**
+idea (short-term experience → long-term competence). One "night":
 
-Inside an epoch, the trainer maintains a step buffer containing:
-
-- compact failure-pattern summaries from previous steps
-- rejected edits and their score deltas
-
-That context is fed back into later reflection calls so the teacher can avoid repeating ineffective edits and can focus on unsolved error patterns.
-
-### Epoch-Level Mechanisms
-
-This branch supports three optional epoch-level mechanisms.
-
-#### Slow Update
-
-At the end of each epoch, `slow_update` compares the previous epoch’s terminal skill and current epoch’s terminal skill on a sampled train subset. It then writes longitudinal guidance into a protected slow-update region inside the skill document.
-
-Importantly, this guidance is **not** blindly written through. It is converted into a candidate skill and sent through the same selection gate as step-level updates.
-
-#### Meta Skill
-
-`meta_skill` is teacher-side cross-epoch memory. It does not directly edit the current skill. Instead, it writes a compact memory artifact describing longer-term patterns across adjacent epochs. That memory is loaded into later reflection / merge / ranking calls as extra context.
-
-#### Meta Reflect
-
-`meta_reflect` runs at epoch end over the step history of the current epoch. It looks at accepted and rejected directions from the whole epoch, proposes higher-level patch edits, applies them to a meta candidate, and then sends that candidate through the same selection gate.
-
-## What This Branch Guarantees
-
-The current implementation assumes the following as the mainline method contract:
-
-- gate validation is always on
-- the current skill, current score, best skill, and best score stay aligned
-- `slow_update` is gated before being committed
-- patch provenance (`source_type`, `support_count`) reaches selection
-- patch application is observable through per-edit reports
-- resume state is restored from `runtime_state.json` rather than inferred only from history
-- all benchmark model calls go through the unified backend router
-
-## Model Backends
-
-All model access now goes through the split teacher/student model layer in `reflact.model`.
-
-Supported teacher backends:
-
-- `openai_chat`
-- `claude_chat`
-
-Supported student backends:
-
-- `openai_chat`
-- `claude_chat`
-- `codex_exec`
-- `claude_code_exec`
-
-Recommended config shape:
-
-```yaml
-model:
-  teacher_backend: openai_chat
-  student_backend: codex_exec
-  teacher: gpt-5.4
-  student: gpt-5.4-codex
-  reasoning_effort: medium
+```
+harvest session transcripts → mine recurring tasks → replay offline
+   → consolidate (reflect → bounded edit → GATE on real held-out tasks)
+   → stage proposal → (you) adopt
 ```
 
-Legacy `model.backend` and CLI flags like `--backend codex` still work. They are mapped onto the split backend model for backward compatibility.
+**Plugins for three agents** (one engine, three thin shells — see [`plugins/`](plugins/)):
 
-The same routing is used by:
-
-- training (`scripts/train.py`)
-- eval-only runs (`scripts/eval_only.py`)
-- SpreadsheetBench standalone prompt eval scripts
-- LiveMathematicianBench baseline eval script
-- benchmark rollout code inside the main framework
-
-### Azure OpenAI
-
-If you use `openai_chat`, configure either environment variables or config values:
-
-```bash
-export AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
-export AZURE_OPENAI_API_KEY="your-api-key"
-export AZURE_OPENAI_API_VERSION="2025-04-01-preview"
-```
-
-The config supports both the old keys and the new explicit names:
-
-```yaml
-model:
-  azure_openai_endpoint: "..."
-  azure_openai_api_version: "..."
-  azure_openai_api_key: ""
-  azure_openai_auth_mode: api_key
-  azure_openai_ad_scope: "https://cognitiveservices.azure.com/.default"
-  azure_openai_managed_identity_client_id: ""
-```
-
-`azure_openai_auth_mode` can be used for API-key auth or Azure AD / managed identity flows.
-
-### Exec Harness
-
-`codex_exec` and `claude_code_exec` run the student inside a workspace harness instead of a plain chat call. The harness writes task files, renders a dynamic `SKILL.md`, runs the student CLI, and saves raw execution artifacts such as:
-
-- `codex_raw.txt`
-- `codex_trace_summary.txt`
-- workspace-local task / skill files
-
-This branch keeps `meta_skill` and `apply_patch_with_report`, while upgrading the student path to the more realistic workspace-exec setup.
-
-### Trace-Aware Deep Reflect
-
-When `student_backend=codex_exec` and `gradient.use_deep_reflect=true`, deep reflection can probe a specific earlier Codex attempt:
-
-- the teacher sees a compact Codex trace summary
-- deep probe can target `probe_target_id`
-- the follow-up rollout can resume from `probe_after_step`
-
-This is wired for the dataset-backed environments in this branch.
-
-### Rewrite Mode
-
-Skill updates support two modes:
-
-- `optimizer.skill_update_mode=patch`
-- `optimizer.skill_update_mode=rewrite_from_suggestions`
-
-`patch` keeps the existing fine-grained edit application path and still records `edit_apply_report.json`.
-
-`rewrite_from_suggestions` asks the teacher to emit higher-level rewrite suggestions, then rewrites the whole skill in one pass. This is useful when patch edits become too fragmented.

-### Important Branch Rule
+**Validated on real models.** On the public
+[gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1` benchmark,
+deficient skills go **0.00 → 1.00** on held-out sets with **both Claude and
+Codex** (all 4 seeds, including a real tool-use loop), cross-model transfer is
+positive, and the gate blocks regressions
+([full results](docs/sleep/FINAL_REPORT.md)).
 
-`use_gate=false` is intentionally not supported in this branch. Gate validation is part of the method contract here.
+> **Open-source tool, decoupled from the research.** The engine lives in the
+> top-level [`skillopt_sleep/`](skillopt_sleep) package with **zero dependency**
+> on the paper's `skillopt/` experiment code (the validation gate is vendored).
+> Controls — optional gate, multi-rollout contrastive reflection, token/time
+> budget, multi-objective reward, user preferences, optimizer/target split — are
+> documented in [`docs/sleep/CONTROLLABLE_DREAMING.md`](docs/sleep/CONTROLLABLE_DREAMING.md).
 
-If an old config still contains `evaluation.use_gate: false`, the loader / trainer will raise instead of silently continuing.
+Deterministic proof (no API key): `python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves`.
 
-## Supported Environments
+---
 
-The main training entry and eval-only entry now register 11 environments:
+## Extensibility & WebUI
 
-| Env | Default rollout shape | Current default split / data setting | Branch alignment |
-|---|---|---|---|
-| `alfworld` | environment-backed episodic rollout | native ALFWorld train/eval splits | in `reflact_new_zzw` |

-| `swebench` | mini-swe-agent multi-step bug-fixing rollout | `split_mode=ratio`, `dataset_name=lite`, repo-stratified `2:1:7` split materialized under `out_root/_generated_splits/...` unless `split_dir` is provided | added here, aligned to `swe-bench-old` |
+### Adding a new backend
 
-## Data Expectations
+A backend = a chat / exec target (e.g. `openai_chat`, `claude_chat`,
+`qwen_chat`, `minimax_chat`, `codex_exec`, `claude_code_exec`). See
+[`docs/guide/new-backend.md`](docs/guide/new-backend.md) for the full
+contract; in short you add a `skillopt/model/<name>_backend.py` module,
+register it in `skillopt/model/common.py` + `backend_config.py`, and wire
+it through the router in `skillopt/model/__init__.py`. `qwen_backend.py`
+and `minimax_backend.py` are good templates.
 
-The standard two-mode dataset entry path is:
+### Adding a new benchmark
 
-- `split_mode: ratio`
-  - load raw data from `env.data_path`
-  - build a deterministic `train/`, `val/`, `test/` split under `env.split_output_dir` (or under `out_root/_generated_splits/` if unset)
-  - default ratio is explicitly `2:1:7`
-- `split_mode: split_dir`
-  - load an existing `env.split_dir` with `train/`, `val/`, `test/` subdirectories
+A benchmark = a `skillopt/envs/<name>/` package with a `dataloader.py`, a
+`rollout.py`, and an `initial.md` seed skill. See
+[`docs/guide/new-benchmark.md`](docs/guide/new-benchmark.md) for the full
+contract; the simplest reference is `skillopt/envs/searchqa/`.
 
-This currently applies to:
+### WebUI
 
-- `searchqa`
-- `spreadsheetbench`
-- `babyvision`
-- `livemathematicianbench`
-- `mmrb`
-- `swebench`
-
-`ALFWorld` is the exception: it is environment-backed rather than JSON split-backed.
-
-The following environments currently expect prepared split directories or extra rooted assets rather than the generic ratio-split path:
-
-- `docvqa`
-- `mathverse`
-- `officeqa`
-- `sealqa`
-
-At a high level:
-
-- `SearchQA`: raw QA json / jsonl or pre-split QA json files
-- `SpreadsheetBench`: raw task manifest json plus spreadsheet task directory, or a pre-split task manifest
-- `ALFWorld`: installed game environment and configured eval/train splits
-- `BabyVision`: raw `meta_data.jsonl` plus images, or a pre-split directory
-- `DocVQA`: pre-split CSV / JSON data under `split_dir`
-- `LiveMathematicianBench`: raw monthly QA json files, or a pre-split directory
-- `MathVerse`: split files plus `data_root` image assets
-- `MMRB`: raw extracted dataset json files, or a pre-split directory
-- `OfficeQA`: pre-split metadata plus resolved office document directories
-- `SealQA`: pre-split metadata for tool-augmented QA tasks
-- `SWEBench`: HuggingFace SWE-bench dataset alias (`lite` / `verified` / `full`) or a prepared split directory
-
-### Split References Across Branches
-
-The split-related defaults are not identical across `skillopt-final`, `reflact_new_zzw`, `gepa`, and `swe-bench-old`. The practical reference points are:
-
-| Source branch | Explicit split settings / dirs |
-|---|---|
-| `skillopt-final` | `searchqa -> data/searchqa_split`; `spreadsheetbench -> data/spreadsheetbench_split`; `docvqa -> data/docvqa_split`; `officeqa -> data/officeqa_split`; `sealqa -> data/sealqa_split`; `swebench -> ratio split 2:1:7 over the default lite dataset, materialized under out_root/_generated_splits/...` |
-| `reflact_new_zzw` | Same 10-benchmark env set as above except no `swebench`; explicit split dirs are `data/searchqa_split`, `data/spreadsheetbench_split`, `data/docvqa_split`, `data/officeqa_split`, `data/sealqa_split`; `spreadsheetbench` there defaults to `mode=single`; `officeqa` uses `max_tool_turns=24`; `sealqa` uses `max_tool_turns=12` |
-| `gepa` | `configs/spreadsheetbench.yaml` uses `data.splits_dir = data/spreadsheetbench/splits`, `eval.mode = react`, `eval.max_turns = 20`; `configs/swebench.yaml` uses `dataset = SWE-bench/SWE-bench_Verified` with `train_size = 100`, `val_size = 50`, `test_size = 350` |
-| `swe-bench-old` | Repo-stratified `2:1:7` split over `SWE-Bench_Lite`, persisted as `outputs/.../split/train.json`, `selection.json`, `test.json`; the example split in that branch is `train=60`, `selection=33`, `test=207` |
-
-For the 10 benches shared with `reflact_new_zzw`, the current branch is now aligned on env coverage. The main intentional delta is `spreadsheetbench`: this branch defaults to multi-round codegen, while `reflact_new_zzw` kept `mode=single` by default.
-
-## Running Training
-
-Example:
+Launch the monitoring dashboard (optional):
 
 ```bash
-python scripts/train.py --config configs/searchqa/default.yaml
+pip install -e ".[webui]"
+python -m skillopt_webui.app
 ```
 
-Explicit 2:1:7 split from raw data:
+| Flag | Default | Description |
+|---|---|---|
+| `--port` | 7860 | Server port |
+| `--host` | `0.0.0.0` | Bind address |
+| `--share` | off | Create a public Gradio share link |
 
-```bash
-python scripts/train.py \
-  --config configs/searchqa/default.yaml \
-  --split_mode ratio \
-  --data_path /path/to/searchqa_train_2000.json

-
-Directly consume a prepared split directory:
-
-```bash
-python scripts/train.py \
-  --config configs/searchqa/default.yaml \
-  --split_mode split_dir \
-  --split_dir /path/to/searchqa_split
-```
-
-You can override structured config keys from the CLI:
-
-```bash
-python scripts/train.py \
-  --config configs/spreadsheetbench/default.yaml \
-  --cfg-options model.teacher_backend=openai_chat model.student_backend=codex_exec train.batch_size=40 optimizer.learning_rate=4
-```
-
-Legacy flat overrides still work for common keys:
-
-```bash
-python scripts/train.py \
-  --config configs/searchqa/default.yaml \
-  --backend azure_openai \
-  --teacher_model gpt-5.4 \
-  --student_model gpt-5.4 \
-  --reasoning_effort medium
-```
-
-Exec harness example:
-
-```bash
-python scripts/train.py \
-  --config configs/searchqa/default.yaml \
-  --teacher_backend openai_chat \
-  --student_backend codex_exec \
-  --teacher_model gpt-5.4 \
-  --student_model gpt-5.4-codex \
-  --use_deep_reflect true \
-  --skill_update_mode rewrite_from_suggestions
-```
-
-SWEBench example:
-
-```bash
-python scripts/train.py \
-  --config configs/swebench/default.yaml \
-  --cfg-options env.dataset_name=lite env.split_ratio=2:1:7
-```
-
-## Eval-Only and Standalone Evaluation
-
-Evaluate a specific skill without training:
-
-```bash
-python scripts/eval_only.py \
-  --config configs/searchqa/default.yaml \
-  --skill reflact/envs/searchqa/skills/initial.md
-```
-
-The same dataset entry modes apply in eval-only runs:
-
-- `--split_mode ratio --data_path ...`
-- `--split_mode split_dir --split_dir ...`
-
-Standalone scripts also exist for benchmark-specific comparisons, including:
-
-- `scripts/eval_prompt_custom.py`
-- `scripts/eval_prompt_official.py`
-- `scripts/eval_livemathematicianbench_baseline.py`
-
-These scripts now also support backend selection through the unified model layer.
-
-## Output Structure
-
-Each run writes a structured output directory under `out_root`.
-
-Important top-level artifacts:
-
-- `config.json` — flattened runtime config
-- `history.json` — per-step history records
-- `runtime_state.json` — resume state for current/best skill tracking
-- `best_skill.md` — current best validated skill
-- `skills/skill_vXXXX.md` — persisted skill snapshot per step
-
-Per-step artifacts live under `steps/step_XXXX/`, including:
-
-- `merged_patch.json`
-- `ranked_edits.json`
-- `candidate_skill.md`
-- `edit_apply_report.json`
-- `rewrite_result.json` when rewrite mode is enabled
-- `selection_eval/`
-- `trajectory_digest.json`
-- rollout and patch subdirectories
-
-Epoch-level artifacts live under:
-
-- `slow_update/epoch_XX/`
-- `meta_skill/epoch_XX/`
-- `meta_reflect/epoch_XX/`
-
-## Resume Behavior
-
-The trainer resumes from `runtime_state.json` when present. That state tracks:
-
-- last completed step
-- current skill path
-- current score
-- best skill path
-- best score
-- origin tags for current and best skill
-
-This is important because skill state can change at both step level and epoch level; resuming only from `history.json` is not sufficient for this branch’s method logic.
-
-## Notes
-
-- This repository focuses on skill optimization logic; datasets are not included.
-- Patch application is intentionally observable. Inspect `edit_apply_report.json` when candidate skills do not behave as expected.
-- `SpreadsheetBench` now defaults to `mode=multi`. If you run an exec student backend there, override back to `env.mode=single` because exec backends are still only wired for SpreadsheetBench single-mode rollout.
-- `SWEBench` follows the older mini-swe-agent + `swebench.harness.run_evaluation` path, so it requires the SWE-bench / Docker toolchain rather than the generic chat-only stack.
-- `slow_update` writes into a protected skill region and normal edits are prevented from overwriting that region directly.
-- `meta_skill` is context memory, not a direct skill edit.
-- `meta_reflect` is a gated skill edit stage, not just logging.
-
-## Minimal Setup
-
-```bash
-conda create -n reflact python=3.11
-conda activate reflact
-pip install openai pyyaml openpyxl
-```
-
-Depending on the environment, you may also need:
-
-```bash
-pip install datasets gymnasium numpy ray regex
-```
-
-For `SWEBench`, you also need a working Docker environment plus the SWE-bench / mini-swe-agent dependencies used in `swe-bench-old`.

+# Paper-aligned SkillOpt reference skills (GPT-5.5)
+
+This folder provides a subset of the paper's main Table 1 GPT-5.5 optimized
+skills as reference artifacts — one `gpt5.5_skill.md` per currently included
+benchmark. You can plug them into `scripts/eval_only.py` to evaluate the
+provided skills on a given split without re-running the training loop.
+
+> These are checkpoints associated with the paper, not a general-purpose
+> tool. They're here so you can verify the reported numbers and use the
+> skills as portable artifacts. If you want to *train* your own skill,
+> use `scripts/train.py` per the top-level README.
+>
+> This is the first artifact batch. We plan to continue uploading the
+> remaining optimized skills and benchmark split manifests as they are
+> cleaned and verified.
+
+## What's here
+
+| Benchmark | Skill artifact | Matching config |
+|---|---|---|
+| SearchQA | `ckpt/searchqa/gpt5.5_skill.md` | `configs/searchqa/default.yaml` |
+| ALFWorld | `ckpt/alfworld/gpt5.5_skill.md` | `configs/alfworld/default.yaml` |
+| DocVQA | `ckpt/docvqa/gpt5.5_skill.md` | `configs/docvqa/default.yaml` |
+| LiveMathematicianBench | `ckpt/livemath/gpt5.5_skill.md` | `configs/livemathematicianbench/default.yaml` |
+| OfficeQA | `ckpt/officeqa/gpt5.5_skill.md` | `configs/officeqa/default.yaml` |
+| SpreadsheetBench | `ckpt/spreadsheetbench/gpt5.5_skill.md` | `configs/spreadsheetbench/default.yaml` |
+
+Each file is a plain Markdown skill document (~2k–13k chars). It contains a
+protected `SLOW_UPDATE` section at the end that holds epoch-wise
+longitudinal guidance — that's expected, not a formatting issue.
+
+## How to evaluate a provided skill
+
+`scripts/eval_only.py` runs a single skill against a data split without
+invoking the optimizer. Example for SearchQA against the test split:
+
+```bash
+python scripts/eval_only.py \
+  --config configs/searchqa/default.yaml \
+  --skill ckpt/searchqa/gpt5.5_skill.md \
+  --split valid_unseen \
+  --split_dir data/searchqa_id_split \
+  --azure_openai_endpoint https://your-resource.openai.azure.com/ \
+  --target_model gpt-5.5
+```
+
+Substitute the benchmark, config, skill path, and `--split_dir` to evaluate
+any of the other five. `--split valid_unseen` is the test split, `valid_seen`
+is the selection / validation split, `train` is the training split, and
+`all` runs all three.
+
+## On comparing to the paper numbers
+
+To compare against the paper-reported cells, use the same dataset split and
+scorer. SearchQA's split is checked in at `data/searchqa_id_split/` (400
+train / 200 selection / 1400 test). For the other benchmarks, point
+`--split_dir` at your own materialized split; the loader is deterministic
+from `split_seed` (default `42`) + `split_ratio` (default `2:1:7`) when
+`split_mode: ratio` is used, so a given `data_path` + seed reproduces
+across machines. Explicit per-benchmark split manifests are being prepared
+for upload — see issues #14 and #21.
+
+## Why force-accept vs. gated slow-update matters
+
+These `ckpt/` skills were produced with the gated slow-update semantics
+described in paper Section 3.6:
+
+```yaml
+optimizer:
+  slow_update_gate_with_selection: true
+```
+
+Current `main` defaults to `false` (force-accept mode), a newer
+post-submission behavior where the slow-update guidance is written into
+`current_skill` and `best_skill` unconditionally at the epoch boundary. If
+you re-train with the current default, you may produce a *different*
+`best_skill.md` than the one checked in here. Both modes are supported;
+see the top-level README's "Configuration -> Slow-update acceptance mode"
+section.

+# ALFWorld Embodied Agent Skill
+
+## Overview
+This skill guides agents operating in the ALFWorld text-based embodied environment.
+The agent must complete household tasks by navigating rooms, interacting with objects,
+and using appliances. Actions must be chosen from the admissible action list provided
+at each step.
+
+**Output format**: Always output `<think>...</think>` for reasoning, then `<action>...</action>` for the chosen action.
+
+---
+
+## Task Types
+
+| Type | Goal | Key Steps |
+|------|------|-----------|
+| Pick & Place | Put object X in/on receptacle Y | Find X -> take X -> go to Y -> put X in/on Y |
+| Pick Two & Place | Put two instances of X in/on Y | Find X1 -> take -> place -> find X2 -> take -> place |
+
+### Pick Two Object Bookkeeping
+For `pick_two_obj_and_place`, choose one destination receptacle instance once it is opened/usable, and remember it as the target. Both object instances should be placed into that same remembered receptacle. After placing the first object, do not remove it again; if the second object was already seen, return directly to its remembered location rather than searching randomly. If the two objects are accidentally split across different receptacles, consolidate them into the chosen target receptacle.
+| Examine in Light | Examine object X under desklamp | Find X -> take X -> find desklamp -> use desklamp |
+
+| Examine in Light detail | Final interaction | While holding X where a desklamp is visible, use the desklamp; do not try to place X on the lamp first. |
+| Clean & Place | Clean object X and put in/on Y | Find X -> take X -> go to sink -> clean X -> go to Y -> put X |
+| Heat & Place | Heat object X and put in/on Y | Find X -> take X -> go to microwave -> heat X -> go to Y -> put X |
+| Cool & Place | Cool object X and put in/on Y | Find X -> take X -> go to fridge -> cool X -> go to Y -> put X |
+
+---
+
+## General Principles
+
+1. **Decompose the task**: Parse the goal into ordered sub-goals (locate, acquire, transform, deliver). Complete each before moving to the next.
+2. **Systematic exploration**: Search each surface and container exactly once before revisiting. Open closed containers (drawers, cabinets, fridge) before judging them empty.
+
+- Prioritize semantically likely locations first, then broaden systematically: food in fridges/on countertops or dining tables; dishes/utensils/cookware on countertops, dining tables, stoveburners, cabinets, or drawers; office/bedroom items on desks, shelves, dressers, sidetables, or in drawers; newspapers on coffeetables, sidetables, sofas, or tvstands; toiletries/cleaning items near sinks, bathroom counters, shelves, carts, or cabinets.
+
+- For portable kitchen targets such as bread, mugs, cups, plates, bowls, and utensils, check broad exposed surfaces early: after one or two empty countertops, try dining tables or other open surfaces before opening many cabinets/drawers. For small office/bedroom targets, alternate drawers with exposed desks, shelves, sidetables, and dressers rather than exhausting drawers first.
+
+- Keep a persistent **searched set** of receptacle instances, e.g. `drawer 1`, `shelf 3`, `countertop 2`. Once an observation shows no needed target object there, mark it searched and do not call it “unexplored” later.
+   - If all locations in the current preferred class are searched, **broaden to any unvisited admissible `go to ...` location** instead of restarting the same sequence. Search broadly across surfaces, furniture, containers, and appliances when relevant.
+   - If a visible object is itself an openable/container-like object, such as a box, and opening/examining it is admissible, inspect it before leaving the area.
+3. **Grab immediately**: When a required object is visible and reachable, take it right away before moving elsewhere.
+
+- Pick up only the exact requested object type. Similar or related objects, such as a cup when the task asks for a mug, a spoon when it asks for a knife, or a pot when it asks for a pan, are distractors; leave them in place and mark that location searched for the target.
+4. **Transform before placing**: If the task requires cleaning, heating, or cooling, perform the state change at the appropriate appliance before heading to the final destination.
+
+- Do not repeatedly revisit the sink, microwave, fridge, or final destination before holding the target object. If you find the appliance early, remember its location, then resume searching unvisited object locations until the target object is acquired.
+
+- Use direct admissible appliance/tool commands immediately when available, such as `clean X with sinkbasin`, `heat X with microwave`, `cool X with fridge`, or `use desklamp`. Do not waste steps opening, closing, toggling, or examining the appliance unless the needed action is unavailable or opening is required for searching/placing.
+5. **Direct delivery**: Once holding the transformed (or untransformed) goal object, navigate straight to the target receptacle and place it.
+
+- Remember known destination receptacles and return directly to the same instance after pickup/transformation. If the destination is also a semantically likely source location, check/open it early rather than only after exhaustive search: food may already be in the fridge, utensils may be on the diningtable, newspapers may be on/near the sofa, and a target drawer can be opened early for pick-two tasks. If the object starts at the destination but needs cleaning/heating/cooling, take it out, transform it, then return to that same instance and place it back.
+6. **Track progress**: Maintain an internal count of how many objects still need to be found and placed. Only stop searching when the count reaches zero.
+7. **Avoid loops**: Never repeat the same action more than twice in a row. If stuck, move to a different unexplored location.
+8. **Only choose admissible actions**: Always pick an action from the admissible action list. Do not invent actions.
+
+---
+
+## Common Mistakes to Avoid
+
+- **Revisiting searched locations**: Keep track of which surfaces/containers have been checked; do not re-examine them.
+- **Ignoring visible objects**: If the target object appears in the observation, pick it up immediately.
+- **Skipping state changes**: Do not place an object at the destination without first cleaning/heating/cooling it when required.
+- **Premature termination**: Do not stop the episode until all goal conditions are verified as met.
+- **Action loops**: Repeatedly toggling or examining the same object wastes steps. Move on to new locations instead.
+
+### Hard Search-Loop Recovery
+
+- **Exact-instance lockout before pickup**: once a receptacle/surface instance has been observed and does not contain the target object, do not go back to that exact instance while still searching for the object. A phase change, such as holding the object or needing final delivery, is the only reason to return.
+- **Fast broadening threshold**: after 3-4 misses in the same receptacle class, switch to a different likely class or any unvisited admissible location instead of continuing or restarting that class, unless the target has already been seen there.
+- **No search reset by recency**: do not say a location is "unsearched" merely because it was not in the last few observations. The searched set is global for the whole episode.
+- **Finite-class exhaustion**: if all visible instances of a small class have been checked once, such as all stoveburners, diningtables, countertops, or shelves, mark that class exhausted for object search and do not start a second pass. Remember a usable destination instance, then search different receptacle classes.
+- **Unvisited beats likely-but-searched**: after several misses, prefer any admissible unvisited `go to`, `open`, or `examine` target over revisiting a semantically likely but already-searched location.
+- **Destination surfaces before pickup**: if the destination receptacle is also a likely object location, inspect each instance at most once before pickup. If it lacks the object, remember it as the final destination but stop using it as a search target until the object has been transformed and is ready to place.
+- **Kitchen item fallback**: for cookware and dishware, after checking obvious burners/tables/counters once, broaden to unsearched cabinets, drawers, shelves, sinkbasins, and other kitchen storage/surfaces rather than cycling among the obvious locations.
+
+### Strict Search Ledger Action Filter
+
+Before every empty-handed search action, apply this hard filter:
+
+1. If a required target object is visible, take it immediately.
+2. Otherwise choose an exact receptacle/surface/container instance whose contents have not yet been observed in the current object-search phase.
+3. Reject any `go to`, `examine`, or `open` action for an exact instance already observed to lack the target, even if it is semantically likely, nearby, recently mentioned, or the final destination type.
+4. If all likely instances are rejected by the ledger, broaden to any unvisited admissible location/class instead of restarting from instance 1 of a searched class.
+
+The searched ledger survives inventory checks, appliance visits, placing the first object in a pick-two task, and putting down an irrelevant inspected object/container. These events are not permission to rescan shelves, drawers, cabinets, tables, counters, or destination receptacles from the beginning.
+
+### Destination-as-Source Lockout
+
+When the final receptacle type is also a plausible source location, inspect each visible destination instance at most once before pickup. After it lacks the target, remember a usable destination instance and lock that exact instance out of object search until you are holding the required object ready for delivery. Do not alternate between destination instances and other searched source instances while still empty-handed.
+
+### Pick-Two Phase Memory
+
+After placing the first object in a pick-two task, do not begin a fresh room/class search. If another required instance was previously seen, return directly to that remembered source location for the second pickup. If no second instance is remembered, continue from the existing unsearched-location ledger rather than revisiting locations already checked before the first placement.
+
+<!-- SLOW_UPDATE_START -->
+Preserve the successful pattern: when the exact requested object is visible, take it immediately; perform the required clean/heat/cool/use action as soon as the correct command is admissible; then deliver directly to the remembered destination.
+
+Treat tool locations as tools, not repeated search targets. If a sinkbasin, fridge, microwave, desklamp, or destination receptacle has already been checked and does not contain the target while you are empty-handed, remember it for later but do not revisit it until you are holding the required object or ready to place/use it.
+
+Use a next-unsearched-instance pointer for every numbered class. If you leave cabinets, drawers, shelves, countertops, or stoveburners and later return to that class, resume at the lowest exact instance not yet observed; never restart at instance 1 and never revisit an instance already observed to lack the target.
+
+For pan-to-stoveburner tasks, search in a step-efficient order: make one quick pass over stoveburners only to find a pan or remember an empty destination, then leave stoveburners until delivery. Next check countertops/islands and sinkbasins. Then prioritize cabinets in numeric order, opening each closed cabinet and observing its contents, before low-yield drawers. Do not abandon cabinet search to revisit searched stoveburners, countertops, or drawers.
+
+For kettle/teapot clean-and-place tasks, after checking obvious countertops/islands, check stoveburners and sinkbasins once, then cabinets in numeric order. If several cabinets are empty, continue to the next unsearched cabinet or broaden to unvisited shelves/carts/dining tables; do not return to already searched countertops. Remember one open/empty cabinet as the final destination, but do not keep using searched cabinets as search targets.
+
+For dishsponge clean-and-place tasks, check sinkbasin and nearby countertops once, then search unvisited cabinets, drawers, shelves, carts, and other storage/surfaces. Because the sink is needed for cleaning, remember it after the first visit; do not go back to the sink while empty-handed just because the sponge is likely near it. Because shelf is the destination, remember a usable shelf after inspecting it once; after a shelf lacks the sponge, search only unvisited shelves or other unvisited locations until the sponge is found.
+
+When the step budget is running and you are still empty-handed, prefer any unvisited admissible location over any searched likely location. A location being semantically likely, useful later, or recently mentioned is never a reason to rescan it before acquisition.
+
+Do not let the broadening threshold cause class restarts. Broadening means move to a different unvisited class or continue at the next unsearched instance of a promising storage class; it never means cycling back through exact instances already observed.

+- Prefer the smallest exact text span that answers the question.
+
+- For questions asking for a value, count, page number, date, or graph reading, return only the requested value span; omit nearby labels, category names, units, or explanatory words unless the question explicitly asks for them.
+- When several nearby strings look similar, choose the one whose surrounding labels or layout best match the question.
+
+## Exact Answer Discipline
+- Copy names, numbers, and dates exactly from the document whenever possible.
+
+- Preserve the document's exact spelling and punctuation for names and quoted phrases; do not substitute similar letters or change straight/curly quotes, spacing, or parentheses when the visible text provides them.
+- Prefer direct extraction over paraphrase.
+- Before finalizing, compare the answer against nearby alternatives and keep the best-supported exact span.
+
+## Structured Layout Lookup
+- For tables, first find the row or entry named in the question, then read the value under the requested column, header, date, or category; answer with that cell only.
+- For forms, receipts, or labeled fields, locate the exact role, party, or field label mentioned in the question, then copy the filled-in value from the same line, box, block, or immediately adjacent field.
+- For table-of-contents, indexed, numbered, or bulleted lists, match the requested title, entry, or point number, then follow the same line or list item to the associated value; do not take a nearby value from another item.
+
+## Anchored Handwriting / Nearby Text
+- For handwritten or list/table questions with an anchor term, first locate the anchor, then inspect the immediately adjacent text in the same row, column, or nearby margin. If legible, provide the best-supported nearby span rather than leaving the answer blank.

+# Live Mathematical MCQ Heuristics
+
+## Option Comparison
+
+### Meta-Options About Stronger Results
+- Treat options of the form “one of the remaining options is correct, but a stronger result can be proven” as serious candidates, especially when the question asks for the strongest statement.
+- If a concrete option is true but your theorem or derivation gives a strictly stronger conclusion not exactly listed, choose the meta-option rather than the weaker concrete statement.
+- When options are nested by strength, rank them explicitly before answering: e.g. finite-time blowup is stronger than merely “not globally bounded”; positive stable growth is stronger than ordinary unboundedness; sharper constants, rates, exceptional-set bounds, endpoint inclusion, or full equivalences are stronger than weaker asymptotic versions.
+- Compare all options before committing. The correct choice is often the strongest statement justified by the question, while nearby distractors are weaker, overstrong, or miss an equality case.
+- Track exact quantifiers such as "there exists", "for every", "if and only if", and "exactly when".
+
+## Theorem-Level Precision
+
+- Do not add converse, realization, or classification claims unless the theorem explicitly proves them. Phrases such as “conversely,” “every such parameter occurs,” “if and only if,” or “exactly all” add strength beyond a one-way implication.
+- Check whether an option weakens the conclusion by dropping a characterization, equality clause, or full equivalence.
+- Check whether an option overstates the theorem by upgrading regularity, removing scale restrictions, or changing an existential statement into a universal one.
+
+## Hypotheses
+
+### Exact Conditions and Thresholds
+- For biconditional/equivalence questions, reject conditions that are merely necessary or merely sufficient. A broader condition, such as congruence modulo a divisor instead of modulo the full modulus, is usually weaker and not equivalent unless the domain collapses the extra cases.
+- For threshold conditions, verify the exact sign and endpoint: distinguish \(\mu_0\) from \(-\mu_0\), \(<\) from \(\le\), and whether the equality case belongs to the positive, zero, or negative parameter regime.
+- When options differ by “for every” vs “for sufficiently large,” local vs global domains, strict vs non-strict inequalities, or dependence of constants, rank them by logical strength and match the sharpest justified version.
+- Verify the hypotheses and domain carefully. Distractors often keep the theorem shape but alter the required assumptions.
+- Pay close attention to equality cases, extremal conditions, and whether a result applies to the full family or only a restricted subfamily.
+
+## Final Answer
+- Output the final answer as the single option label only.
+
+## Exact Scope and Quantitative Wording
+- Distinguish global conclusions from localized or completed ones. Equivalence after localization, completion, or at each prime/scale is usually weaker than an unqualified equivalence.
+- In estimate-heavy options, compare every quantitative detail: exponent, derivative index range, constants and their parameter dependence, log factors, additive terms, one-sided vs two-sided notation, and pointwise vs uniform convergence.

+## Retrieval Discipline
+
+- When an external official time-series observation is needed, prefer the source's series/data-download/table page once identified. If exact-date or guessed-value searches return empty results, stop repeating them; broaden to the official series name/code plus `data` or `download` and use the table values.
+
+- Treat provided/oracle parsed pages as primary evidence: if they contain the relevant table and period, extract directly from them before searching elsewhere; search only for missing continuation pages, missing periods, or an official actual value not present.
+- Start by narrowing to the most likely candidate file before reading long passages.
+- Prefer targeted search terms that name the exact entity, period, measure, or table concept from the question.
+- After a promising match, read only a small surrounding span and verify it matches the requested year, basis, and unit.
+
+- If the requested date range extends beyond the provided/oracle page, first enumerate the required periods and verify that every period is present in evidence. Do not compute from a partial ledger or fill missing periods from memory; retrieve continuation pages, adjacent issues, or a later issue of the same table that contains the missing dates/revisions.
+
+## Evidence Discipline
+- Extract the exact value from the retrieved text before doing any arithmetic.
+- Keep track of each operand's period, unit, and semantic role so nearby proxy values are not mixed in.
+
+- For Treasury financing narratives, label each amount by transaction role before calculating: offered amount, tenders/subscriptions received, tenders accepted, competitive/noncompetitive accepted, foreign or Government-account exchange tenders, refunding, and **new cash** are not interchangeable.
+- When converting currencies or scales, make a direction ledger first: source table unit, source currency, exchange-rate orientation (foreign currency per U.S. dollar means divide by the rate; U.S. dollars per foreign unit means multiply), and requested final unit.
+
+- For tables, align values by row label and exact column header, not proximity alone; watch for continued or unlabeled columns, footnotes, adjacent amount-versus-percent columns, fiscal-year versus calendar-year sections, and repeated month rows under different year blocks.
+- If the question asks for a transformed or derived quantity, compute only after confirming every operand.
+
+- For derived comparisons, preserve the direction and sign implied by the wording: “change from A to B” means B minus A; “former than latter” means former minus latter; “share accounted for by X” means X divided by the stated total; paired “gap” questions require computing each within-row difference before ranking.
+- For statistical, regression, correlation, and growth-rate questions, write a formula ledger before calculating: confirm the exact series/endpoints, ordered vector, elapsed intervals, and requested convention such as continuously compounded rate, CAGR, Pearson correlation, or OLS index/year choice.
+- For multi-stage questions where one table determines the period/entity used in another lookup, freeze that derived key with evidence first, then retrieve the second measure only for that exact month/year/reporting date/entity.
+
+- For inclusive time-series ranges, make a period-by-period ledger covering every requested month/year exactly once, preserving calendar versus fiscal basis, end-of-month or end-of-fiscal-month status, source units, and any specified adjustments.
+
+- For statistical transforms over time-series windows, confirm endpoint inclusion/exclusion exactly as worded, use consecutive time indices for trend regressions when appropriate, sort values before medians, and for logarithmic growth use ln(final/initial) before converting to the requested percentage format.
+
+## Final Answer Discipline
+
+- Before finalizing, enforce the requested unit and format: convert thousands/millions/billions or full nominal dollars as needed, then apply no-comma, fixed-decimal, whole-number, or nearest-tenth/thousandth formatting exactly as asked.
+- Return the final answer only after one last consistency check against the retrieved evidence.
+- Copy the final answer from a checked value, not from an unverified intermediate guess.
+
+## Statistical and Time-Series Calculation Checks
+
+- Before computing any statistic, write the intended formula and denominator convention. If the prompt explicitly says **population standard deviation**, divide by `n`; if it says **sample**, divide by `n-1`; for a z-score comparing one observation against a small set of comparison months/periods and no population convention is stated, estimate dispersion with the **sample** standard deviation of the comparison set. Do not round intermediate operands, weighted averages, logs, exchange-rate conversions, or standard deviations before the final requested rounding.
+- For long inclusive ranges, first enumerate the expected count of observations and the first/last period, then verify the ledger has exactly that count. Exclude totals, cumulative-to-date columns, comparable-period columns, estimates, and extra latest-month columns outside the requested calendar or fiscal range.
+- When a page contains multiple nearby sections with similar labels, use only the section whose title and row label match the requested measure exactly; do not compute from the first visible table if the requested measure/table title is absent or only partially shown.
+- For Treasury security quotations, obey the table's quote basis. If the table states that price decimals are 32nds, convert quotes such as `99.27` as `99 + 27/32`, not as decimal `99.27`. If a task asks for smoothing, averaging, or forecasting in a target currency using period-specific exchange rates, convert each period's observation to the target currency first unless the prompt explicitly says to compute in the source currency and convert only the final result.
+
+## Stricter Final Formatting
+
+- Match any requested output template exactly. Unless the prompt explicitly asks for unit words or explanatory text, return only the numeric value or requested list; do not append words such as `million`, `dollars`, `percent`, or `percentage points`. Include symbols/commas only when the prompt requests currency-formatted output or the answer format clearly requires them.

+# Question Answering Skill
+
+(No learned rules yet. Rules will be added through the reflection process.)
+
+## Concise Answer Normalization
+- Prefer the shortest unambiguous answer that directly satisfies the question. Do not include generic descriptors, legal suffixes, or expanded formal names unless the question specifically asks for the full official name or the descriptor is necessary to identify the entity.
+
+- If the answer appears inside a longer descriptive phrase, strip words that merely repeat the clue's requested type or modifiers already stated in the clue. For short-answer trivia, return the distinctive core entity or headword rather than role titles, product flavor adjectives, or place/facility designators, even when those words are part of a fuller official phrase, unless the full official name is explicitly requested.
+- For place/name-etymology questions asking for “the name” or “the word” that means something, answer the distinctive name/word itself rather than a larger phrase with a generic type label.
+
+- For natural geographic features, preserve conventional feature designators such as “Lake,” “River,” “Bay,” “Gorge,” “Mount,” or “Island” when they are part of the proper name or match the requested feature type. Do not shorten “Lake Okeechobee,” “Tampa Bay,” or “Olduvai Gorge” to an ambiguous base name merely to be concise.
+- For companies, brands, and organizations, answer the common distinctive name when sufficient; omit additions such as “Company,” “Corporation,” “Inc.,” etc. unless explicitly required.
+
+- Preserve the answer surface form supported by the strongest evidence when exact variants differ: spelling, capitalization, punctuation, and word order can matter. Do not substitute an equivalent official/common variant such as an alternate spelling or inverted institution name if a direct title/snippet/answer field gives the expected form.
+
+- When copying titles or quoted names, preserve ordinary ASCII punctuation from the evidence, especially straight apostrophes (`'`). Do not replace them with typographic curly quotes/apostrophes unless that exact stylized form is explicitly shown as the supported answer.
+
+- For nicknames, epithets, saints, and quoted titles, copy the supported surface form exactly, including spacing, capitalization, and conventional abbreviations such as “St.” Do not normalize a stylized or quoted form into a lowercase dictionary word or an expanded spelling when the clue/evidence points to the stylized answer.
+
+- For person answers in trivia or crossword-style clues, prefer the conventional supported name. Use just a surname, first name, or saint/regnal name only when the clue/source clearly expects that short form; otherwise use the canonical full personal name from the strongest evidence or answer field, especially when a lone given name would be ambiguous.
+- Return the grammatical base form expected by the clue. Do not add a plural `s` merely because a crossword source pluralizes a shared name or category; if the clue lists people sharing a first name, answer the singular given name.
+
+- For common-noun category answers, default to the singular dictionary headword in trivia/crossword-style clues, even if the clue uses plural words like “these,” “those,” “places,” or “items” for grammar. Use a plural only when the term is inherently plural or an answer field/source clearly gives a plural phrase.
+
+- For common-noun clues about things being replaced, used in place of, or substituted by another system/item, answer the broad headword for the thing replaced unless a narrowing modifier is required by the clue or answer field. Do not add adjectives such as “letter,” “regular,” or “standard” merely because they appear in explanatory context.
+- For fill-in-the-blank or definitional clues using words like “this” or “that,” provide a standalone noun phrase. Avoid context-dependent pronouns or possessives from the source text; use a natural article such as “the” when needed (e.g., answer “the highest point,” not “its highest point”).
+
+## Context-Grounded Evidence Matching
+- Start by identifying the most distinctive terms in the question: proper names, dates, titles, quoted phrases, unusual words, roles, relationships, and category descriptors.
+- Prioritize passages or document titles where several distinctive clue terms occur together, especially if the wording directly repeats or closely paraphrases the question.
+- Treat document titles as useful evidence: the answer is often named in a title while the snippet confirms the clue facts.
+
+- Do not assume the document title itself is the answer. If the requested type differs from the title entity, use the title as context and extract the matching typed entity from the snippet or clue relationship.
+
+- For “known as,” “called,” “defined as,” or category/type clues, choose the canonical term explicitly used in the strongest matching title/snippet or scraped answer field rather than inventing a related derivative or near-synonym from the clue wording. When multiple plausible candidates appear, prefer the candidate whose evidence directly states the requested relationship and repeats the most distinctive clue facts.
+- Ignore noisy results that only match generic words; prefer evidence that directly connects the clue facts to one specific entity.
+
+## Clue Interpretation and Answer Type
+- For Jeopardy-style wording such as “this man,” “this group,” “this film,” “this country,” “this system,” “he,” or “his wife,” infer the expected answer type before choosing the answer.
+- Use that expected type to validate candidates: answer with the concise person, place, title, organization, object, term, or phrase requested by the clue.
+
+- Treat modifiers attached to the requested type as hard filters, not background flavor: constraints like dates, “largest,” “2-letter-named,” “1978 remake,” “hot dog brand,” “dual throne,” or “on this company’s board” must all fit the candidate before you answer.
+- For clues centered on creative works such as books, films, plays, songs, poems, or other media, first determine whether the clue asks for the work itself, its creator, a performer or cast member, a character, a quotation source, or a setting. Verbs such as “wrote,” “directed,” “stars,” “played,” and “set in,” plus pronouns like “he” or “her,” usually determine the target.
+
+- For fill-in-style clues with placeholders such as “this,” “these,” or “one of these,” substitute each candidate back into the clue and choose the concise answer that makes the full phrase, title, or fact read correctly.
+- For terse clues that are just examples or names separated by commas, slashes, or “or,” infer the shared category, class, or synonym that links them, then answer with that concise common term.
+
+- For crossword-style clues, treat parenthetical numbers or stated letter counts as hard constraints on the answer length, and omit generic labels that would violate them. In dual-definition clues using wording like “X, or what Y does,” choose the single word that satisfies both senses and preserve the required inflected form.
+- If the clue references an unavailable image or link with wording like “seen here,” “pictured,” or parenthetical visual hints, rely on the textual clues and context to infer the answer; do not treat the missing image as necessary evidence.
+- If multiple snippets support the same entity, use that corroboration to choose the canonical/common form of the answer.
+
+## Trivia / Jeopardy Snippet Formats
+- Retrieved trivia snippets may contain the clue and answer in scraped formats such as `CATEGORY | clue | answer`, `clue. ANSWER`, or labels like `right:`.
+- When the question text matches the clue in such a snippet, extract the answer field or adjacent answer name, not the category or the whole clue sentence.
+
+## Common Clue Traps
+- Watch for inverse relationships: if the clue says “His third wife was Jiang Qing,” the requested answer is the husband, not Jiang Qing.
+
+- More generally, preserve relation direction in clues: “A is evidence of this B,” “A is related to this language,” or “home to these characters” asks for the target of the relationship, not the entity already named in the clue.
+
+- When a clue says examples, models, breeds, members, or items “include,” “like,” or “such as” named entities, treat those names as evidence for the requested parent class or entity. Answer the encompassing brand, animal, category, place, or term requested by “this,” not one of the examples already given.
+- If the question gives the start of a quotation or phrase, answer with the exact missing continuation from the context.
+
+- For song, poem, nursery-rhyme, or quotation clues, first decide whether the question asks for a missing word or phrase from the quote or for the associated creator, performer, or work; use pronouns and answer-type signals to choose the right target.
+- When a clue asks for a constrained form such as a first name, abbreviation, acronym, or lyric word, return that exact form rather than the fuller person, title, or explanation; preserve conventional punctuation or spelling when it is part of the requested form.
+- If the clue contains wordplay, quotation marks, or puns, treat them as hints, but answer with the real entity supported by the evidence.
+
+- If a clue includes a quoted title, quoted narration or lyric, named event, slogan, or other distinctive phrase but asks for an associated “this” entity, treat the quote or name as evidence to identify the requested person, work, place, group, category, source, or term; do not return the quoted anchor unless the clue explicitly asks for it.

+# Spreadsheet Manipulation Skill (xlsx)
+
+## Overview
+This skill guides agents in manipulating Excel (.xlsx) spreadsheets using Python.
+
+**Primary libraries**: `openpyxl` (structure-preserving read/write), `pandas` (data transformation).
+Never use any other third-party libraries.
+
+---
+
+## Common Workflow
+
+1. **Explore** the input file: list sheets, inspect headers, check dimensions.
+
+- Inspect actual workbook data beyond the preview, including nearby rows/columns, sample outputs, formulas, labels, headers, and any reference/example sheets such as `Output`, `Manual Result`, or `Desired...` tabs.
+
+- Treat existing filled cells in the requested output area or adjacent example tables as semantic examples for edge cases and expected formats, but still recompute and write the complete requested target range.
+   - Scan the used range for complete header groups, not just row 1. Tables may start in later rows/columns, have title rows above them, or have multiple source/result tables on the same sheet; use nearby labels and the requested output range to distinguish sources from destinations.
+   - Locate tables, fields, and target ranges by header text, nearby labels, and surrounding nonblank structure rather than fixed coordinates. Build header maps from actual cells when useful, e.g. `{str(cell.value).strip(): cell.column}`.
+2. **Write `solution.py`** with `INPUT_PATH` and `OUTPUT_PATH` defined at the top.
+3. **Execute** `python solution.py` and verify the output file was created.
+4. **Confirm** the target cells/range contain the expected values.
+
+---
+
+## Library Selection
+
+| Use case | Library |
+|----------|---------|
+| Preserve formulas, formatting, named ranges | `openpyxl` |
+| Bulk data transformation, aggregation, sorting | `pandas` → write back with `openpyxl` |
+| Simple cell read/write | `openpyxl` |
+
+**Warning**: `pandas.to_excel()` silently destroys existing formulas and named ranges.
+When writing back to a spreadsheet that contains formulas, always use `openpyxl.save()`.
+
+**Formula evaluation caution**: `openpyxl` can write formulas but does **not** calculate them or update cached results. If the requested output will be checked as cell values, compute the result in Python and write literal values unless the user explicitly requires live formulas. When existing formulas are inputs to your logic, load a second workbook with `data_only=True` to read cached values while saving changes through the normal workbook:
+
+```python
+wb = openpyxl.load_workbook(INPUT_PATH)
+wb_values = openpyxl.load_workbook(INPUT_PATH, data_only=True)
+ws = wb["Sheet1"]
+ws_values = wb_values["Sheet1"]
+```
+
+Treat wording such as “write/fix a formula,” “SUMIFS/COUNTIFS,” “VBA,” or “macro” as a description of the spreadsheet logic unless the deliverable explicitly requires live formula text, an `.xlsm`, or a preserved VBA project. For normal `.xlsx` outputs, implement the equivalent logic in Python/openpyxl and write the computed final values to the requested cells so verification does not depend on Excel recalculation or macros.
+
+When the user provides an existing or broken formula, use it as a semantic specification: honor its referenced lookup ranges, criteria ranges, return ranges, aggregation intent, and error-handling behavior, then write the resulting values rather than guessing different source columns or leaving unevaluated formulas.
+
+---
+
+## solution.py Template
+
+```python
+import openpyxl
+import pandas as pd
+
+INPUT_PATH  = "..."   # set to the actual input path
+OUTPUT_PATH = "..."   # set to the actual output path
+
+wb = openpyxl.load_workbook(INPUT_PATH)
+ws = wb.active  # or wb["SheetName"]
+
+# --- perform manipulation ---
+
+wb.save(OUTPUT_PATH)
+```
+
+---
+
+## Output Requirements
+
+- Save the result to `OUTPUT_PATH`.
+- Do not hardcode row counts or column letters — iterate over actual rows in the workbook.
+- Preserve sheets and cells not mentioned in the instruction.
+
+## Matching and Target Range Hygiene
+
+- Choose the comparison operator from the instruction and examples: use `startswith` for “begins with”, substring search for “contains/search/occurrence”, and exact normalized equality only when a whole-cell match is implied.
+- Create small helper functions for comparisons and numeric parsing. Normalize text by trimming, collapsing repeated spaces/NBSPs, and casefolding; when names or labels have punctuation/spacing inconsistencies, consider punctuation-insensitive keys. Parse numeric text after removing commas/currency symbols while preserving signs and decimal points; skip `None`/blank and booleans for numeric tests, and handle placeholders such as `"-"`, `"$"`, `"$0"`, blanks, and numeric zero deliberately.
+- Normalize date keys deliberately: handle `datetime`/`date` objects, Excel serial numbers, and date-like strings, then compare at the granularity implied by the task, such as exact date, month, month/year, fiscal period, or year. For workday/date-window logic, compute the range in Python and exclude weekends/holidays as specified.
+
+- For monthly or period summary grids, canonicalize period labels from all sources: sheet names, title text, row/column headers, text months such as `March`, and actual date cells. Match summaries by normalized period plus the other stated criteria rather than by fixed month offsets or existing formulas.
+- For date ranges and rolling windows, infer endpoint inclusivity from wording and examples. Phrases like `X to Y`, `through`, and `up to`, or examples such as `2 to 5` meaning `4 days`, usually require inclusive boundary handling.
+- For time extraction or time-threshold logic, parse `datetime`, `time`, Excel serial/fractional times, and time-like strings into real Python `time`/`datetime` values. Write real time values with an Excel `number_format` such as `hh:mm:ss AM/PM`; do not write text substrings when the result should behave as a time.
+- For joins, deduplication, grouping, interval lookups, lookup grids, and ordered outputs, build explicit normalized keys, including composite keys when the task refers to multiple fields. Preserve original source order within each group unless sorting is explicitly requested.
+- For outputs that depend on other rows or lookup grids, make a first pass to build normalized dictionaries/groups/range structures, then a second pass to write results. Avoid nested full-sheet scans per row; split delimited tokens and ignore empty tokens, and treat error literals such as `#N/A` as meaningful sentinel values when the task refers to them.
+
+- For lookups, filters, joins, and label/header matching, normalize comparison keys consistently: trim whitespace, skip blanks explicitly, use case-insensitive text matching when appropriate, and treat numeric-looking IDs consistently (`330`, `330.0`, and `"330"`). Keep numeric outputs numeric; use `number_format` for display formatting instead of converting numbers to strings unless text is explicitly required.
+- When replacing a generated output area, clear only the instructed target range before writing new results so stale values/formulas do not remain. Preserve formatting, column widths, borders, formulas, and unrelated cells unless the instruction explicitly asks to change them.
+
+- If the instruction includes formatting changes, apply them exactly after writing values and only to the requested cells/range. Use `openpyxl` styles for fills, alignment, fonts, borders, and number formats; convert hex colors to ARGB when needed, for example `#FFC000` → `FFFFC000`. For “format as text,” set `number_format = '@'` and write string values when the expected cell values are text.
+
+- When the instruction names a destination range or columns, write derived results directly there. Do not insert rows/columns, relocate the source table, or sort/delete source records unless that structural change is explicitly requested.
+- For filtered lists, summaries, and aggregations, first collect all source records/results in memory, preserving the required order, then write from the first output row and clear leftover cells below the new results in the target columns. When adding rows, copy style/alignment/number format from an existing template row when appropriate; when deleting rows, delete from bottom to top to avoid row-index shifts.
+- Preserve intended blanks as empty cells (`None`) rather than placeholder text or `0` unless the task specifies otherwise.
+
+- For numeric aggregation, crosstab, SUMIFS-like, and INDEX/MATCH-style summary outputs, infer missing-match behavior from table semantics and examples: numeric summary grids usually require literal `0` for no matching records, while filtered lists or “show only once” outputs usually require blanks (`None`).
+- For blank-sensitive logic such as “if input is blank, output blank,” evaluate the driving input with `data_only=True` when it may itself be a formula, and write `None` for truly blank outputs rather than relying on a new formula returning `""`.
+
+## Robustness for Simple Fill Tasks
+
+- Prefer simple, auditable row/column loops over complex workbook XML parsing unless the task truly requires unsupported workbook internals. Before returning, run the script once to catch syntax/indentation errors and verify that representative target rows were actually written.
+
+<!-- SLOW_UPDATE_START -->
+When the user asks for a formula, macro, VBA code, or a fix to an Excel formula, still deliver the completed workbook state: compute the intended results in Python and write literal final values into the requested cells. Do not write formula strings unless the task explicitly says the output must contain live formulas.
+
+After writing, reload or inspect the saved workbook and verify that every requested/evaluated target cell contains a non-formula literal where a value is expected. If a target cell is still `None` unexpectedly, fix the script before finishing.
+
+Use existing formulas in the workbook as examples/specifications, not as output. If a cell contains a reference formula such as `=A25` or an INDEX/MATCH/SUMIFS pattern, parse what source cells/ranges/criteria it refers to, compute those results yourself, and overwrite the destination with the referenced or calculated value.
+
+For blank-sensitive formula tasks, compute the branch explicitly: if the driving source cell is truly blank, write `None`; otherwise write the actual result such as `0`, `1`, a category label, or a lookup value. Never rely on `IF(...,"",...)` formulas to be recalculated later.
+
+For lookup/category tasks, locate both the input rows and the lookup table by headers and nearby labels. Support exact keys, numeric-looking keys, and interval/range tables; then fill every destination row that has a driving input, not just the first visible example.
+
+For “every nth row” or OFFSET-style tasks, infer the source column, first source row, and step from the provided examples or formulas, then copy the actual source values into the requested output range as literals.
+
+For schedule/calendar fill tasks, build a cycle-day-to-periods mapping from the schedule/template area first, then fill the daily rows across all requested class columns based on each row’s cycle day. Preserve repeated/double periods exactly as shown by the template; do not leave formulas in the schedule cells.
+
+For INDEX/MATCH problems where the first row works but subsequent rows fail, treat row labels, column/year headers, region/type criteria, and expense/category labels as a multi-key lookup. Fill the whole result matrix with values from the source data table, using cached `data_only` values when source cells are formulas.
+
+For multi-step macro/VBA-style requests, implement every stated operation in the workbook, not just the first deletion/filtering step. Re-read the numbered requirements before saving and verify later computed columns, totals, and derived fields as well as the obvious filtered rows.
+
+When a target range includes special rows such as `Total`, `Grand Total`, `min`, `max`, constraints, headers, or blank separators, do not apply ordinary row logic blindly to those rows. Compute totals as aggregates when indicated, and leave constraint/header/blank cells untouched unless explicitly requested.
+
+For residual-balancing tasks, identify data rows separately from min/max constraint rows. Add positive residuals from unit 1 toward unit 5 without exceeding max values; subtract negative residuals from unit 5 toward unit 1 without going below min values; update only the unit cells in actual data rows.
+
+For time-threshold rows, decide per row whether it is a normal data row or a summary row. Normal rows use the before/after threshold rule; summary rows should aggregate the computed normal-row results if the workbook labels or examples indicate a total.
+
+Keep scripts simple enough to run cleanly. Avoid unnecessary dynamic code generation and fragile f-strings with regex expressions inside them. Always execute the final `solution.py`; fix any syntax, indentation, or runtime error, then verify representative target cells.
+
+If workbook cells contain arbitrary sample text that could be sensitive or trigger content filters, do not quote large raw cell contents in your response. Process them locally in Python with neutral variable names and output only the completed script/workbook changes.

-# Ablation Study Configuration Manifest
-
-This folder records the final, reproducible settings for the ablation runs used
-in `docs/ablation_paper_tables.md`.
-
-It is intentionally separate from the benchmark default configs. The benchmark
-configs under `configs/<benchmark>/default.yaml` remain the source task configs;
-this folder records the exact matrix-level overrides, run roots, launch commands,
-and validation rules used for the paper ablations.
-
-## Files
-
-- `matrix.yaml`: canonical ablation matrix, common overrides, benchmark splits,
-  token/output caps, and invalid-run rules.
-- `launch_commands.sh`: exact launcher commands for the valid run roots.
-- `validation.md`: monitoring, result extraction, and invalidation checklist.
-
-## Source Of Truth
-
-Use the matrix launcher:
-
-```bash
-/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python scripts/run_ablation_matrix.py
-```
-
-The launcher builds runs from the same defaults and values recorded in
-`matrix.yaml`. It skips completed runs by checking `summary.json` and skips
-active runs by checking `env.out_root` in active `scripts/train.py` processes.
-
-Do not manually rerun a completed run into the same `env.out_root`. If a run is
-invalid, archive or remove its output directory first, then let the launcher
-start it cleanly.
-
-## Current Correct Run Roots
-
-- SearchQA / SpreadsheetBench original ablations:
-  `outputs/ablation_20260502_040604_unique48`
-- SearchQA / SpreadsheetBench batch-size ablations:
-  `outputs/ablation_batch_searchqa_spreadsheet_20260503_153902_run`
-- LiveMathBench / ALFWorld clean ablations:
-  `outputs/ablation_livemath_alfworld_clean_20260503_155155_run`
-- DocVQA ablations:
-  `outputs/ablation_docvqa_20260503_160225_run`
-
-Archived, superseded, misaligned, dry-run, or pre-fix directories must not be
-used for paper tables.
-
-## End-To-End Runbook
-
-### Environment
-
-Run from the repository root:
-
-```bash
-cd /home/azureuser/workspace-gzy/SkillReflection
-```
-
-Always use:
-
-```bash
-PY=/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python
-export ALFWORLD_DATA=/home/azureuser/.cache/alfworld
-```
-
-Default model/auth settings are generated by `scripts/run_ablation_matrix.py`:
-
-```text
-teacher=gpt-5.5
-student=gpt-5.5
-teacher_backend=openai_chat
-student_backend=openai_chat
-reasoning_effort=medium
-teacher/student endpoint=https://t2vgoaigpt4o3.openai.azure.com/
-teacher/student api_version=2024-12-01-preview
-teacher/student auth_mode=azure_cli
-```
-
-Core training settings:
-
-```text
-train.num_epochs=4
-train.train_size=0
-train.batch_size=40
-train.accumulation=1
-train.seed=42
-gradient.minibatch_size=8
-gradient.merge_batch_size=8
-gradient.analyst_workers=16
-gradient.use_deep_reflect=false
-optimizer.learning_rate=4
-optimizer.min_learning_rate=2
-optimizer.lr_scheduler=cosine
-optimizer.lr_control_mode=fixed
-optimizer.use_slow_update=true
-optimizer.slow_update_samples=20
-optimizer.use_meta_skill=true
-optimizer.use_meta_reflect=false
-optimizer.longitudinal_pair_policy=mixed
-evaluation.use_gate=true
-evaluation.eval_test=true
-env.split_mode=split_dir
-```
-
-`train.train_size=0` is intentional. The dataloader derives the train size from
-the fixed split. Batch-size ablations rely on the default `ceil(train_size /
-batch_size)` behavior; the last batch can be smaller than `train.batch_size`.
-
-### Fixed Splits
-
-Default split directories:
-
-```text
-searchqa: data/ablation_splits/searchqa/2-1-7_seed42
-spreadsheetbench: data/ablation_splits/spreadsheetbench/2-1-7_seed42
-livemathematicianbench: data/ablation_splits/livemathematicianbench/2-1-7_seed42
-alfworld: data/ablation_splits/alfworld/2-1-7_seed42
-docvqa: /home/azureuser/zisu/SkillReflection/data/docvqa/splits
-```
-
-Default train/val/test sizes:
-
-| Benchmark | Train | Val | Test |
-| --- | ---: | ---: | ---: |
-| SearchQA | 400 | 200 | 1400 |
-| SpreadsheetBench | 80 | 40 | 280 |
-| LiveMathBench | 35 | 18 | 124 |
-| ALFWorld | 39 | 18 | 134 |
-| DocVQA | 1070 | 535 | 3744 |
-
-DocVQA images are not copied. The valid setup uses:
-
-```text
-data/docvqa_images -> /home/azureuser/zisu/SkillReflection/data/docvqa_images
-```
-
-2026-05-05 DocVQA data correction: all DocVQA final reruns should use the zisu
-10% split above and a fresh output root such as
-`outputs/ablation_docvqa_zisu10pct_20260505_run`. The older local
-`data/ablation_splits/docvqa/2-1-7_seed42` contains the same 5349 questionId
-pool but a different train/val/test assignment, so its completed summaries are
-historical only.
-
-### Matrix Groups
-
-Use these group names with `scripts/run_ablation_matrix.py`:
-
-```text
-default split batch mbs lr sched slown mod smodel longpair lrctrl
-```
-
-`longpair` is the slow-update/meta-skill comparison-example ablation. It keeps
-all prompts and training settings unchanged and only overrides:
-
-```text
-optimizer.longitudinal_pair_policy=changed
-optimizer.longitudinal_pair_policy=unchanged
-```
-
-The default paper setting remains `mixed`.
-
-`lrctrl` contains the two learning-rate-control baselines:
-
-```text
-optimizer.lr_control_mode=autonomous
-optimizer.lr_control_mode=none + optimizer.skill_update_mode=full_rewrite_minibatch
-```
-
-The autonomous run logs the chosen integer per step in `lr_decision.json` and
-`lr_history.jsonl`. The full-rewrite run removes the LR/edit-selection concept:
-each minibatch analyst produces a complete skill candidate, and aggregate/merge
-produces the candidate skill directly.
-
-Batch-size values are:
-
-```text
-8 / 24 / 40 / 56 / full
-```
-
-`40` is the default point. `full` expands to the benchmark train size.
-
-### Launch Commands Used In This Session
-
-The exact commands are recorded in `launch_commands.sh` and in
-`docs/ablation_plan.md`. The important current policy is:
-
-- SearchQA / SpreadsheetBench batch-only matrix can run at `--max-parallel 8`.
-- DocVQA matrix can run with its launcher at `--max-parallel 8`; later top-up used `--max-parallel 16` only because completed runs were skipped and active roots were checked.
-- LiveMathBench is safe as API-only benchmark after the token cap fix.
-- ALFWorld must not be mixed into a 24-way run on this shared machine. Use `--bench alfworld --max-parallel 1` only after memory is available.
-
-### Token And Timeout Fixes
-
-LiveMathBench must use a large student completion cap:
-
-```text
-max_completion_tokens=16384
-timeout=300
-```
-
-The old 768/512 cap produced many empty visible responses because hidden
-reasoning consumed the budget.
-
-ALFWorld must use:
-
-```text
-max_completion_tokens=2048
-empty response fallback -> <action>look</action>
-missing action fallback -> <action>look</action>
-```
-
-### Invalid Runs
-
-Never fill paper tables from these archive directories:
-
-```text
-outputs/ablation_livemath_alfworld_clean_20260503_155155_run/archive_livemath_token768_20260504_022258/

-```
-
-### Current Resource Notes
-
-ALFWorld model calls are API calls. The ablation branch now creates local
-ALFWorld/TextWorld environments through multiprocessing workers ported from
-`skillopt_final_zzw`, not through Ray actors. Old Ray-based archived runs are
-not valid for table fill. The observed historical failure mode in this session
-was system RAM pressure and Ray OOM prevention, not model GPU memory.
-
-GPU memory currently shown by `nvidia-smi` came from unrelated Ray Serve visual
-models under:
-
-```text
-/home/azureuser/workspace-gzy/zyf/gca-skill
-```
-
-Those processes are `GroundingDINOModel` / `DA3Model`, not the
-SkillReflection ablation ALFWorld run.
-
-There are also unrelated ALFWorld jobs under:
-
-```text
-/home/azureuser/zisu/skill_distill
-```
-
-Do not confuse those with this repository's ablation outputs.
-
-### Monitoring
-
-Active run and duplicate output-root check:
-
-```bash
-$PY - <<'PY'
-import subprocess, re, collections, time
-try:
-    raw = subprocess.check_output(["pgrep", "-af", "scripts/train.py"], text=True)
-except subprocess.CalledProcessError:

-roots = []
-for line in raw.splitlines():
-    m = re.search(r"env\.out_root=([^\s]+)", line)
-    if m:
-        roots.append(m.group(1))
-ctr = collections.Counter(roots)
-print("time", time.strftime("%F %T"))

-# Ablation Validation Checklist
-
-Use this checklist before launch, during monitoring, and before filling
-`docs/ablation_paper_tables.md`.
-
-## Before Launch
-
-Run from repo root:
-
-```bash
-cd /home/azureuser/workspace-gzy/SkillReflection
-export ALFWORLD_DATA=/home/azureuser/.cache/alfworld
-```
-
-Verify syntax for edited files:
-
-```bash
-/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python -m py_compile \
-  scripts/run_ablation_matrix.py \
-  scripts/train.py \
-  reflact/model/azure_openai.py \
-  reflact/envs/searchqa/rollout.py \
-  reflact/envs/spreadsheetbench/rollout.py \
-  reflact/envs/livemathematicianbench/rollout.py \
-  reflact/envs/alfworld/rollout.py \
-  reflact/envs/docvqa/rollout.py
-```
-
-Check active runs and duplicate `env.out_root` before starting more:
-
-```bash
-/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python - <<'PY'
-import subprocess, re, collections
-try:
-    raw = subprocess.check_output(["pgrep", "-af", "scripts/train.py"], text=True)
-except subprocess.CalledProcessError:
-    raw = ""
-roots = []
-for line in raw.splitlines():
-    m = re.search(r"env\.out_root=([^\s]+)", line)
-    if m:
-        roots.append(m.group(1))
-ctr = collections.Counter(roots)
-print("train_count", len(roots))
-print("duplicate_roots", [r.rsplit("/", 1)[-1] for r, c in ctr.items() if c > 1])
-for root in sorted(roots):
-    print(root.rsplit("/", 1)[-1])
-PY
-```
-
-## During Monitoring
-
-Check launchers:
-
-```bash
-pgrep -af 'scripts/run_ablation_matrix.py' || true
-tail -80 outputs/ablation_docvqa_20260503_160225_run/launcher_parallel8.log 2>/dev/null || true
-tail -80 outputs/ablation_livemath_alfworld_clean_20260503_155155_run/launcher_livemath_parallel8.log 2>/dev/null || true
-tail -80 outputs/ablation_livemath_alfworld_clean_20260503_155155_run/launcher_alfworld_parallel1.log 2>/dev/null || true
-```
-
-Scan current logs for new hard failures:
-
-```bash
-rg -n "Traceback|ERROR|Error code|AuthenticationError|BadRequest|RateLimit|content_filter|Killed|OutOfMemory|\\[FAIL\\]|\\[RETRY\\]" \
-  outputs/ablation_docvqa_20260503_160225_run/logs \
-  outputs/ablation_livemath_alfworld_clean_20260503_155155_run/logs \
-  outputs/ablation_batch_searchqa_spreadsheet_20260503_153902_run/logs \
-  -g '*.log' | tail -160 || true
-```
-
-Check resource pressure:
-
-```bash
-df -h /tmp
-du -sh /tmp/ray 2>/dev/null || true
-free -h | sed -n '1,3p'
-```
-
-## Quality Checks
-
-LiveMathBench current valid runs should not look like old 768/512 runs:
-
-```bash
-/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python - <<'PY'
-import json, pathlib
-root = pathlib.Path("outputs/ablation_livemath_alfworld_clean_20260503_155155_run")
-for run in sorted(root.glob("*livemathematicianbench*")):
-    if not run.is_dir() or "archive" in str(run):
-        continue
-    for rel in ["test_eval_baseline/results.jsonl", "test_eval/results.jsonl"]:
-        p = run / rel
-        if not p.exists():
-            continue
-        rows = [json.loads(l) for l in p.open(errors="ignore") if l.strip()]
-        empty = sum(1 for r in rows if not str(r.get("response", "")).strip())
-        answer = sum(1 for r in rows if "<answer>" in str(r.get("response", "")).lower())
-        if empty:
-            print(run.name, rel, "empty", empty, "answer", answer, "n", len(rows))
-PY
-```
-
-ALFWorld valid runs must not contain empty action or missing action:
-
-```bash
-/home/azureuser/workspace-gzy/miniconda3/envs/reflact/bin/python - <<'PY'
-import json, pathlib
-root = pathlib.Path("outputs/ablation_livemath_alfworld_clean_20260503_155155_run")
-for run in sorted(root.glob("*alfworld*")):
-    if not run.is_dir() or "archive" in str(run):
-        continue
-    bad = []
-    fallback = 0
-    for c in run.glob("**/conversation.json"):
-        data = json.load(c.open(errors="ignore"))
-        for step in data:
-            if step.get("step") is None:
-                continue
-            if not step.get("action"):
-                bad.append(str(c.relative_to(run)))
-                break
-            mr = str(step.get("model_response", ""))
-            if "empty model response" in mr or "missing action tag" in mr:
-                fallback += 1
-    print(run.name, "bad_action_files", len(bad), "fallback", fallback)
-PY
-```
-
-## Filling Tables
-
-Use only `summary.json` fields:
-
-- `best_selection_hard` -> Best Sel
-- `baseline_test_hard` -> Base Test
-- `test_hard` -> Best Test
-- `test_delta_hard` -> Delta
-- `total_accepts` -> Accept
-- `total_rejects` -> Reject
-- `token_summary._total.total_tokens` -> Tokens
-
-Do not fill table rows from logs alone.

+# ─────────────────────────────────────────────────────────────────────────────
+# Feature: soft / mixed validation-gate metric (community-contributed, PR #25)
+# ─────────────────────────────────────────────────────────────────────────────
+#
+# This is NOT a default SkillOpt setting and was NOT used to produce the
+# numbers reported in the paper. It is provided as a reference for users
+# who encounter a specific scenario where the default `hard` gate is too
+# coarse to drive training.
+#
+# When to consider this:
+#   - You are running on a custom environment.
+#   - Your held-out *selection* split has very few items (e.g. ≤ ~10).
+#   - Your reward function is continuous / partial-credit (e.g. F1, BLEU,
+#     soft match) rather than purely binary 0/1.
+#
+# Symptom this addresses:
+#   With a small selection split + continuous rewards, candidate skills
+#   often improve per-item soft scores (e.g. 0.06 → 0.26 on one item) but
+#   never flip the discrete hard outcome. The default `hard` gate then
+#   rejects every candidate and training stalls. Switching the gate to
+#   `soft` or `mixed` lets these partial improvements be accepted.
+#
+# When NOT to use this:
+#   - When reproducing the paper. The paper-reported numbers were obtained
+#     under the default `hard` gate.
+#   - When your selection split is large (dozens+ items) and / or your
+#     reward is already binary — `hard` is the more conservative choice
+#     and matches the design described in the paper.
+#
+# To use: inherit your env config from this file, e.g.
+#   _base_: ../features/soft_gate.yaml
+# or copy the `evaluation:` block below into your config.
+# ─────────────────────────────────────────────────────────────────────────────

+# Data Manifests
+
+This directory releases lightweight split manifests for the SkillOpt paper
+splits. These manifests are not full runnable benchmark payloads. To evaluate a
+benchmark, first materialize the full examples from the raw data source when
+needed, then point `--split_dir` at the split directory listed below.
+
+In this README, "coverage" describes which part of the upstream benchmark the
+manifest references. It does not mean the released manifest directory contains
+the full runnable examples.
+
+## Layout
+
+Every released manifest directory uses the same file layout:
+
+```text
+data/<benchmark>_<manifest_type>/
+|-- split_manifest.json
+|-- train/items.json
+|-- val/items.json
+`-- test/items.json
+```
+
+`split_manifest.json` records source metadata, split counts, and item fields.
+Each `items.json` contains only stable IDs or source-path hints.
+
+## Released Splits
+
+| Manifest directory | Benchmark | Counts | Coverage | Raw data source | `split_dir` |
+|---|---|---:|---|---|---|
+| `searchqa_id_split/` | SearchQA | 400 / 200 / 1400 | Official HF dataset IDs | [lucadiliello/searchqa](https://huggingface.co/datasets/lucadiliello/searchqa) | `data/searchqa_split` |
+| `livemathematicianbench_id_split/` | LiveMathematicianBench | 35 / 18 / 124 | Four official monthly files | [LiveMathematicianBench/LiveMathematicianBench](https://huggingface.co/datasets/LiveMathematicianBench/LiveMathematicianBench) | `data/livemathematicianbench_split` |
+| `docvqa_id_split/` | DocVQA | 107 / 53 / 374 | 10% subset of validation | [lmms-lab/DocVQA](https://huggingface.co/datasets/lmms-lab/DocVQA) | `data/docvqa/splits` |
+| `officeqa_id_split/` | OfficeQA | 50 / 24 / 172 | OfficeQA Full | [databricks/officeqa](https://huggingface.co/datasets/databricks/officeqa) | `data/officeqa_split` |
+| `spreadsheetbench_id_split/` | SpreadsheetBench | 80 / 40 / 280 | SpreadsheetBench Verified 400 | [KAKA22/SpreadsheetBench](https://huggingface.co/datasets/KAKA22/SpreadsheetBench) | `data/spreadsheetbench_split` |
+| `alfworld_path_split/` | ALFWorld | 39 / 18 / 134 | ALFWorld `json_2.1.1` paths | [alfworld/alfworld](https://github.com/alfworld/alfworld) | `data/alfworld_path_split` |
+
+Counts are ordered as train / val / test.
+
+## Direct Use
+
+Only `alfworld_path_split/` can be used directly as `--split_dir` from this
+release, because the ALFWorld loader reads `gamefile` and `task_type` from the
+split items.
+
+This does not mean the ALFWorld raw data is included. You still need to
+download ALFWorld separately with `alfworld-download` and set `$ALFWORLD_DATA`
+to the data root containing `json_2.1.1`.
+
+The other manifest directories are lookup manifests. They intentionally omit
+full example fields such as questions, answers, contexts, images, or task
+instructions. Materialize those benchmarks into the `split_dir` paths listed
+above before running SkillOpt.
+
+## Lookup Keys
+
+The manifests are sufficient to locate the corresponding raw examples after
+the raw data has been downloaded or otherwise made available:
+
+| Benchmark | Manifest lookup key |
+|---|---|
+| SearchQA | Match `items.json[].id` to the `key` field in `lucadiliello/searchqa`. |
+| LiveMathematicianBench | Open `source_file`, then match `no`; the manifest `id` is `<month>:<no>`. |
+| DocVQA | Match `questionId` within the official DocVQA `validation` split; `image_path` records the expected local image path. |
+| OfficeQA | Match `uid` in `officeqa_full.csv`; `source_files` and `source_docs` identify the supporting document. |
+| SpreadsheetBench | Match `id`; `spreadsheet_path` identifies the referenced spreadsheet directory. |
+| ALFWorld | Resolve `gamefile` relative to `$ALFWORLD_DATA`. |
+

+
+## Benchmark Notes
+
+### SearchQA
+
+`searchqa_id_split/` is an ID-only manifest. Each released `id` exactly matches
+the `key` field in `lucadiliello/searchqa`.
+
+Materialized examples must include the fields consumed by the SearchQA
+environment, including:
+
+```text
+question
+context
+answers
+```
+
+### LiveMathematicianBench
+
+`livemathematicianbench_id_split/` was generated from these raw files:
+
+```text
+data/202511/qa_202511_final.json
+data/202512/qa_202512_final.json
+data/202601/qa_202601_final.json
+data/202602/qa_202602_final.json
+```
+
+The manifest stores IDs in the loader format:
+
+```text
+<month>:<no>
+```
+
+Materialized examples must include:
+
+```text
+question
+choices
+correct_choice
+theorem_type
+theorem
+sketch
+paper_link
+```
+
+### DocVQA
+
+`docvqa_id_split/` records `docvqa_validation_10pct`: a 10% subset sampled from
+the official DocVQA `validation` split.
+
+```text
+source_split: validation
+docvqa_validation_10pct: train=107, val=53, test=374
+```
+
+Each manifest item contains question/document IDs plus image location metadata.
+Materialized examples must provide `question`, `answer` or `ground_truth`, and
+an `image_path` that resolves locally.
+
+### OfficeQA
+
+`officeqa_id_split/` records the split over OfficeQA Full
+(`officeqa_full.csv`). The official OfficeQA CSVs are gated on Hugging Face, so
+materialization requires authorized access.
+
+Each manifest item contains `uid`, `category`, `source_files`, and
+`source_docs` hints. Materialized examples must include `question` and
+`ground_truth` or `answer`.
+
+### SpreadsheetBench
+
+`spreadsheetbench_id_split/` records the split over SpreadsheetBench Verified
+400, from `spreadsheetbench_verified_400.tar.gz`.
+
+Each manifest item contains task identity metadata such as `id`,
+`spreadsheet_path`, and `instruction_type`. Materialization must also place the
+referenced spreadsheet directories at:
+
+```text
+data/spreadsheetbench_verified_400
+```
+
+### ALFWorld
+
+`alfworld_path_split/` records `gamefile` paths relative to `$ALFWORLD_DATA`.
+The source payload is `json_2.1.1`, which must be downloaded separately with
+`alfworld-download`.
+
+This manifest can be used directly as `--split_dir` after `$ALFWORLD_DATA`
+points to the local ALFWorld data root containing `json_2.1.1`.

+# Configuration Guide
+
+SkillOpt uses YAML configuration files with a hierarchical override system.
+
+## Config Structure
+
+```
+configs/
+├── _base_/
+│   └── default.yaml          # Global defaults
+├── searchqa/
+│   └── default.yaml          # SearchQA overrides
+├── docvqa/
+│   └── default.yaml          # DocVQA overrides
+└── alfworld/
+    └── default.yaml          # ALFWorld overrides
+```
+
+Benchmark configs inherit from `_base_/default.yaml` and override specific values.
+
+## Key Parameters
+
+### Model
+
+```yaml
+model:
+  backend: azure_openai          # azure_openai | openai_chat | claude_code_exec | qwen
+  optimizer: gpt-5.5               # Optimizer model (for reflection)
+  target: gpt-5.5               # Target model (for rollout)
+```
+
+### Training
+
+```yaml
+train:
+  num_epochs: 4                  # Number of training epochs
+  batch_size: 40                 # Tasks per step (batch size)
+  accumulation: 1                # Gradient accumulation
+  seed: 42
+```
+
+### Gradient (Reflection)
+
+```yaml
+gradient:
+  minibatch_size: 8              # Reflect minibatch size
+  analyst_workers: 16            # Parallel reflection workers
+  max_analyst_rounds: 3          # Max rounds of analyst reflection
+  failure_only: false            # Only reflect on failures
+```
+
+### Optimizer
+
+```yaml
+optimizer:
+  learning_rate: 4               # Max edits per step (edit budget)
+  min_learning_rate: 2           # Min edits for decay schedulers
+  lr_scheduler: cosine           # constant | linear | cosine | autonomous
+  use_slow_update: true          # Momentum-like blending at epoch boundary
+  slow_update_samples: 20        # Samples for slow update evaluation
+  use_meta_skill: true           # Cross-epoch strategy memory
+```
+
+### Skill-Aware Reflection (optional, off by default)
+
+EmbodiSkill-style failure routing: the failure analyst classifies each
+failure pattern as **SKILL_DEFECT** (the rule is wrong or missing → normal
+gated body edit) or **EXECUTION_LAPSE** (a valid rule exists but was not
+followed → a short reminder appended to a protected appendix region inside
+the skill that step-level edits can never modify).
+
+```yaml
+optimizer:
+  use_skill_aware_reflection: false    # Master switch (default off = baseline-identical)
+  skill_aware_appendix_source: both    # both | failure_only (paper-faithful S_app)
+  skill_aware_consolidate_threshold: 0 # >0: LLM-compact the appendix past N notes (experimental)
+```
+
+Notes:
+
+- The switch is resolved process-wide from the config
+  (`configure_skill_aware_reflection`), so it applies to every benchmark
+  with no per-adapter wiring.
+- `failure_only` restricts appendix notes to the failure analyst, matching
+  the original S_app formulation; `both` additionally lets the success
+  analyst re-emphasize existing rules.
+- Appendix notes bypass the validation gate by design and accumulate with
+  order-preserving dedup; lapse-only steps (no body edits) still flush
+  their notes.
+- Not supported together with `skill_update_mode=rewrite_from_suggestions`
+  or the full-rewrite modes: whole-document rewrites can drop the appendix
+  region.
+
+### Evaluation
+
+```yaml
+evaluation:
+  use_gate: true                 # Validation gating (accept/reject updates)
+  eval_test: true                # Run test evaluation after training
+```
+
+### Environment (Data)
+
+```yaml
+env:
+  name: searchqa                 # Benchmark name
+  split_mode: ratio              # ratio | split_dir
+  split_ratio: "2:1:7"           # train:val:test ratio
+  data_path: ""                  # Path to dataset
+  exec_timeout: 120              # Per-task timeout (seconds)
+```
+
+## CLI Overrides

+```bash
+python scripts/train.py \
+  --config configs/searchqa/default.yaml \

+# Deep Learning ↔ SkillOpt Analogy
+
+SkillOpt is designed around a core insight: **optimizing natural-language prompts follows the same structure as training neural networks**. This page maps every DL concept to its SkillOpt counterpart.
+
+## Complete Mapping
+
+| Deep Learning | SkillOpt | Description |
+|---|---|---|
+| **Model weights** | Skill document (Markdown) | The thing being optimized |
+| **Forward pass** | Rollout | Target executes tasks using current skill |
+| **Loss function** | Task evaluator | Scores task execution quality |
+| **Backpropagation** | Reflect | Optimizer analyzes failures → edit patches |
+| **Gradients** | Edit patches | Proposed changes to the skill |
+| **Gradient aggregation** | Patch aggregation | Merge similar edits |
+| **Gradient clipping** | Edit selection | Cap max edits per step |
+| **Learning rate** | `learning_rate` | Max number of edits applied per step |
+| **LR scheduler** | `lr_scheduler` | Decay schedule: cosine, linear, constant |
+| **SGD step** | Skill update | Apply selected patches to document |
+| **Validation set** | Selection split | Gate checks improvement before accepting |
+| **Early stopping** | Gate patience | Reject updates that don't improve |
+| **Training step** | Step | One rollout → reflect → update cycle |
+| **Epoch** | Epoch | Full pass with slow update + meta memory |
+| **Momentum** | Slow update | Longitudinal comparison at epoch boundary |
+| **Meta-learning** | Meta skill | Cross-epoch optimizer strategy memory |
+| **Batch size** | `batch_size` | Tasks sampled per rollout |
+| **Data parallelism** | `analyst_workers` | Parallel reflection workers |
+| **Training set** | Train split | Items used for rollout |
+| **Test set** | Test split | Held-out final evaluation |
+| **Warm-up** | (implicit) | High LR early steps explore broadly |
+| **Checkpointing** | Skill snapshots | Saved after each accepted step |
+| **Transfer learning** | Seed skill / cross-benchmark init | Start from pre-trained skill |
+
+## Why This Analogy Matters
+
+1. **Familiar mental model**: ML practitioners immediately understand how to tune SkillOpt
+2. **Principled hyperparameter search**: Grid search over `learning_rate` × `lr_scheduler` works just like in DL
+3. **Proven mechanisms**: Gating ≈ validation-based selection, patience ≈ early stopping, slow update ≈ momentum — all with strong theoretical motivation
+
+## Hyperparameter Transfer Rules
+
+From our experiments, these DL intuitions transfer well:
+
+!!! success "What transfers"
+    - **Cosine schedule > constant** — same as in DL, cosine annealing helps convergence
+    - **Moderate LR (4-16) > very high/low** — too few edits = slow learning, too many = noisy
+    - **Slow update helps** — longitudinal comparison prevents catastrophic forgetting across epochs
+    - **Meta skill memory improves reflection** — optimizer benefits from cross-epoch strategy notes
+
+!!! warning "What doesn't transfer"
+    - **Batch size ≠ better** — larger rollout batches have diminishing returns due to API costs
+    - **More epochs ≠ better** — skills converge faster than neural networks (2-4 epochs usually enough)

+# Your First Experiment
+
+This guide walks through running a complete SkillOpt training on SearchQA.
+
+## 1. Choose a Benchmark
+
+SkillOpt includes ready-to-use configs for several benchmarks:
+
+| Benchmark | Difficulty | Typical Runtime |
+|---|---|---|
+| SearchQA | ⭐ Easy | ~30 min |
+| DocVQA | ⭐⭐ Medium | ~2 hours |
+| ALFWorld | ⭐⭐⭐ Hard | ~3 hours |
+
+We'll use **SearchQA** as it's the fastest to complete.
+
+## 2. Configure
+
+Review the config file:
+
+```bash
+cat configs/searchqa/default.yaml
+```
+
+Key parameters (deep learning analogy in parentheses):
+
+```yaml
+train:
+  num_epochs: 4           # (epochs)
+  batch_size: 40          # (batch size)
+
+optimizer:
+  learning_rate: 4        # (max edits per step)
+  lr_scheduler: cosine    # (learning rate schedule)
+  use_slow_update: true   # (momentum at epoch boundary)
+  use_meta_skill: true    # (cross-epoch optimizer memory)
+
+gradient:
+  analyst_workers: 16     # (parallel reflection workers)
+
+evaluation:
+  use_gate: true          # (validation gating)
+```
+
+## 3. Train
+
+```bash
+python scripts/train.py --config configs/searchqa/default.yaml
+```
+
+You'll see output like:
+
+```
+[Step 1/8] Rollout: 20 items, 4 workers...
+[Step 1/8] Score: 0.65 → Reflect...
+[Step 1/8] 6 edit patches generated
+[Step 1/8] Selected 4 edits (lr=8, cosine → 7.7)
+[Step 1/8] Gate: val score 0.68 > 0.65 ✓ ACCEPT
+[Step 2/8] ...
+```
+
+## 4. Monitor
+
+Training outputs are saved to `outputs/<benchmark>/<run_id>/`:
+
+```

+# Local Environment Smoke Tests
+
+This guide describes a lightweight pattern for testing a custom SkillOpt environment before connecting it to expensive model calls or a full benchmark dataset.
+
+The goal is to validate the training loop plumbing first:
+
+- config loading
+- adapter construction
+- dataloader splits
+- rollout output shape
+- reflection patch shape
+- merge/rank/update control flow
+- artifact creation under `out_root`
+
+Once those are stable, you can switch the same environment to real model calls and larger evaluation splits.
+
+## 1. Add a tiny fixture split
+
+Start with a handful of deterministic examples that cover the expected pass/fail cases for your environment. Keep them small enough that a single training step can run locally.
+
+A minimal fixture item usually needs:
+
+```json
+{
+  "id": "example-1",
+  "split": "train",
+  "question": "...",
+  "expected": "..."
+}
+```
+
+Use the split names your adapter maps to SkillOpt phases:
+
+- `train` for optimization rollouts
+- `val` or `valid_seen` for selection/gating
+- `test` or `valid_unseen` for final evaluation
+
+## 2. Support an offline mock mode
+
+Add a configuration flag such as `mock: true` to your adapter. In mock mode, `rollout()` should return deterministic responses without calling external model APIs.
+
+This lets you verify the SkillOpt loop with a fast command such as:
+
+```bash
+python scripts/train.py \
+  --config configs/myenv/tiny_mock.yaml
+```
+
+Mock mode should still write the same artifacts as a real run, for example:
+
+- `responses.json`
+- `rollout_results.json`
+- `ranked_edits.json`
+- `candidate_skill.md`
+- `summary.json`
+
+## 3. Keep the smoke config tiny
+
+A CI-friendly smoke config should run a single small step:
+
+```yaml
+train:
+  num_epochs: 1
+  train_size: 3
+  batch_size: 3
+
+gradient:
+  minibatch_size: 1
+  merge_batch_size: 2
+  analyst_workers: 1
+  max_analyst_rounds: 1
+
+optimizer:
+  learning_rate: 1
+  min_learning_rate: 1
+  lr_scheduler: constant
+  skill_update_mode: patch
+  use_slow_update: false
+
+evaluation:
+  use_gate: true
+  sel_env_num: 2
+  test_env_num: 2
+  eval_test: false
+
+env:
+  name: myenv
+  out_root: outputs/myenv_tiny_mock
+  mock: true
+```
+
+Prefer a mock config that runs without credentials. That makes it useful for contributors and CI.
+
+## 4. Validate optimizer JSON before returning it
+
+If your environment or extension asks an LLM to merge or rank skill edits, validate the returned JSON before passing it back into SkillOpt. This avoids silent fallbacks from empty, malformed, or out-of-range responses.
+
+Useful checks for edit payloads:
+
+- response is a JSON object
+- `edits` is a non-empty list
+- every edit is an object
+- every edit has an allowed operation
+- required fields such as `content` or `target` are present for that operation
+
+Useful checks for ranking payloads:
+
+- `selected_indices` exists
+- indices are integers
+- indices are unique
+- indices are within the candidate edit range
+- selected count does not exceed the edit budget
+
+On failure, retry with a compact prompt that includes the schema error. If retries fail, raise an explicit error instead of silently accepting malformed output.
+
+## 5. Run progressively stronger checks
+
+A good development sequence is:
+
+```bash
+python -m py_compile scripts/train.py skillopt/envs/myenv/adapter.py
+python scripts/train.py --config configs/myenv/tiny_mock.yaml
+python scripts/train.py --config configs/myenv/tiny.yaml
+```
+
+For the real tiny run, verify that:
+
+- the run completes
+- `summary.json` is written
+- `ranked_edits.json` contains the expected ranking metadata
+- any optimizer bridge log marks the response schema as valid
+- no generated files are written outside `out_root`
+
+## 6. Keep custom environments isolated
+
+When adding a custom environment to the registry, avoid side effects for existing benchmarks:
+
+- lazy-import optional dependencies
+- install environment-specific hooks only when `cfg["env"]` matches your environment
+- keep mock behavior behind an explicit config flag
+- write generated artifacts only under `out_root`
+
+This makes it easier to review and test a custom integration without affecting the built-in benchmarks.

+
+## Step 1: Create the Backend
+
+Create `skillopt/model/your_backend.py`:
+
+```python
+from skillopt.model.base import ModelBackend, ModelResponse
+
+class YourBackend(ModelBackend):
+    """Your custom model backend."""
+    
+    def __init__(self, cfg: dict):
+        super().__init__(cfg)
+        self.model_name = cfg.get('model_name', 'your-default-model')
+        self.api_key = os.environ.get('YOUR_API_KEY', '')
+        self.client = self._init_client()
+    
+    def _init_client(self):
+        """Initialize API client."""
+        # TODO: Set up your API client
+        pass
+    
+    async def generate(
+        self,
+        messages: list[dict],
+        temperature: float = 0.7,
+        max_tokens: int = 4096,
+        **kwargs
+    ) -> ModelResponse:
+        """
+        Generate a completion.
+        
+        Args:
+            messages: Chat messages [{"role": "...", "content": "..."}]
+            temperature: Sampling temperature
+            max_tokens: Maximum tokens in response
+            
+        Returns:
+            ModelResponse with content, usage, and metadata
+        """
+        response = await self.client.chat(
+            model=self.model_name,
+            messages=messages,
+            temperature=temperature,
+            max_tokens=max_tokens,
+        )
+        
+        return ModelResponse(
+            content=response.text,
+            usage={
+                'prompt_tokens': response.usage.input,
+                'completion_tokens': response.usage.output,
+            },
+            model=self.model_name,
+        )
+    
+    async def generate_with_tools(
+        self,
+        messages: list[dict],
+        tools: list[dict],
+        **kwargs
+    ) -> ModelResponse:
+        """Generate with tool/function calling support."""
+        # Optional: implement if your model supports tool use
+        raise NotImplementedError("Tool use not supported")
+```
+
+## Step 2: Register the Backend
+
+Add to `skillopt/model/__init__.py`:
+
+```python
+from .your_backend import YourBackend
+
+BACKEND_REGISTRY = {
+    # ... existing backends ...
+    'your_backend': YourBackend,
+}
+```
+
+## Step 3: Configure
+
+Use your backend in any config:
+
+```yaml
+model:
+  backend: your_backend
+  model_name: your-model-id
+  temperature: 0.7
+  max_tokens: 4096
+```
+
+Set credentials via environment variable:
+
+```bash
+export YOUR_API_KEY="your-key"
+```
+
+## Required Interface
+
+Your backend must implement these methods:
+
+| Method | Required | Description |
+|---|---|---|
+| `generate()` | ✅ | Basic text generation |
+| `generate_with_tools()` | Optional | Tool/function calling |
+| `count_tokens()` | Optional | Token counting for context management |
+
+## Tips
+
+!!! tip
+    - Test your backend with `python -c "from skillopt.model.your_backend import YourBackend"` first
+    - Use `async` methods for all API calls — SkillOpt uses asyncio throughout
+    - Implement retry logic with exponential backoff for production use
+    - Add your API key to `.env.example` when submitting a PR

+# Add a New Benchmark
+
+Extend SkillOpt with your own benchmark in ~200 lines of code. We will use
+a tiny worked example, `docfaithful`, that scores a target model on
+how faithfully it answers questions grounded in a small reference doc.
+
+> **Working reference.** The easiest way to copy-cargo-cult a new env is
+> to read [`skillopt/envs/officeqa/`](https://github.com/microsoft/SkillOpt/tree/main/skillopt/envs/officeqa).
+> Everything below is the same shape, simplified.
+
+## What you need to build
+
+To add a benchmark you implement four things:
+
+1. **A `SplitDataLoader` subclass** — knows how to load train / val / test
+   item dicts from disk.
+2. **A rollout helper** — runs the target model on a batch of items
+   under the current skill and scores each prediction.
+3. **An `EnvAdapter` subclass** — wires the loader + rollout helper into
+   SkillOpt's lifecycle (`build_*_env`, `rollout`, `reflect`,
+   `get_task_types`).
+4. **A YAML config** — references your env name plus the standard
+   train / optimizer / gradient knobs.
+
+Then one line in `scripts/train.py`'s `_register_builtins()` makes it
+discoverable.
+
+---
+
+## Step 1 — Create the package
+
+```bash
+mkdir -p skillopt/envs/docfaithful
+touch skillopt/envs/docfaithful/__init__.py
+```
+
+## Step 2 — Implement the data loader
+
+`skillopt/envs/docfaithful/loader.py`:
+
+```python
+from __future__ import annotations
+
+import json
+from pathlib import Path
+
+from skillopt.datasets.base import SplitDataLoader
+
+
+def _normalize(raw: dict) -> dict:
+    """Make sure every item has an ``id``. Other keys are env-specific."""
+    return {
+        "id": str(raw["uid"]),
+        "question": raw["question"],
+        "ground_truth": raw["answer"],
+        "reference_text": raw.get("reference", ""),
+        "task_type": raw.get("category", "docfaithful"),
+    }
+
+
+class DocFaithfulDataLoader(SplitDataLoader):
+    """Load DocFaithful items from JSON files inside each split dir."""
+
+    def load_split_items(self, split_path: str) -> list[dict]:
+        # split_path is e.g. data/docfaithful_split/train/
+        json_files = sorted(Path(split_path).glob("*.json"))
+        if not json_files:
+            raise FileNotFoundError(f"No .json file found in {split_path}")
+        with json_files[0].open(encoding="utf-8") as f:
+            raw = json.load(f)
+        return [_normalize(item) for item in raw]
+```
+
+Only `load_split_items()` is mandatory. If you also want to support
+`split_mode="ratio"` (auto-split a single raw file into train/val/test),
+override `load_raw_items(data_path)` as well — see
+`skillopt/datasets/base.py` docstrings.
+
+## Step 3 — Write the rollout helper
+
+`skillopt/envs/docfaithful/rollout.py`:
+
+```python
+from __future__ import annotations
+
+import json
+import os
+from pathlib import Path
+
+from skillopt.model import chat_target
+
+
+def _score(prediction: str, ground_truth: str) -> tuple[int, float]:
+    """Trivial exact-match scorer. Replace with F1 / ROUGE / LLM-judge."""
+    p = (prediction or "").strip().lower()
+    g = (ground_truth or "").strip().lower()
+    hard = int(p == g and bool(g))
+    soft = 1.0 if hard else 0.0
+    return hard, soft
+
+
+def _rollout_one(item: dict, skill_content: str,
+                 *, max_completion_tokens: int) -> dict:
+    system = skill_content
+    user = (
+        f"Question: {item['question']}\n\n"
+        f"Reference:\n{item.get('reference_text', '')}\n\n"
+        "Answer:"
+    )
+    prediction, _usage = chat_target(
+        system=system,
+        user=user,
+        max_completion_tokens=max_completion_tokens,
+    )
+    hard, soft = _score(prediction, item.get("ground_truth", ""))
+    return {
+        "id": str(item["id"]),
+        "hard": hard,
+        "soft": soft,
+        "predicted_answer": prediction,
+        "question": item.get("question", ""),
+        "reference_text": item.get("reference_text", ""),
+        "task_type": item.get("task_type", "docfaithful"),
+    }
+
+
+def run_batch(*, items: list[dict], skill_content: str, out_root: str,
+              workers: int = 4, max_completion_tokens: int = 4096) -> list[dict]:
+    """Run a batch of episodes sequentially or with a thread pool."""
+    os.makedirs(out_root, exist_ok=True)
+    # For brevity we go sequentially — swap in concurrent.futures.ThreadPoolExecutor
+    # when network / model latency dominates.
+    results = [
+        _rollout_one(item, skill_content,
+                     max_completion_tokens=max_completion_tokens)
+        for item in items
+    ]
+    Path(out_root, "rollouts.json").write_text(
+        json.dumps(results, ensure_ascii=False, indent=2)
+    )
+    return results
+```
+
+Two design points worth flagging:
+
+- **Scoring lives here, not in `EnvAdapter`.** There is no `evaluate()`
+  method on the ABC. Whatever signal you put in `hard` (0/1, or a float
+  in [0, 1] for smoothed reward) and `soft` (float in [0, 1]) is what
+  the optimizer reads.
+- **Use `skillopt.model.chat_target`**, not raw OpenAI/Claude calls.
+  That routes through whichever **chat** target backend the user
+  configured (`openai_chat` / `claude_chat` / `qwen_chat` /
+  `minimax_chat`) without your adapter caring. Exec-style backends
+  (`codex_exec`, `claude_code_exec`) need env-specific rollout code —
+  see `skillopt/envs/swebench/` for an example.
+
+## Step 4 — Implement the environment adapter
+
+`skillopt/envs/docfaithful/adapter.py`:
+
+```python
+from __future__ import annotations
+
+import os
+
+from skillopt.datasets.base import BatchSpec
+from skillopt.envs.base import EnvAdapter
+from skillopt.envs.docfaithful.loader import DocFaithfulDataLoader
+from skillopt.envs.docfaithful.rollout import run_batch
+from skillopt.gradient.reflect import run_minibatch_reflect

+            if tt not in seen:
+                seen.append(tt)
+        return seen or ["docfaithful"]
+```
+
+### What the rollout actually does
+
+Look back at `run_batch` from Step 3 — it sends each `item["question"]`
+to the target model with `skill_content` as the system prompt, scores
+the answer against `item["ground_truth"]`, and returns a list of dicts:
+
+```python
+[
+    {"id": "ex_001", "hard": 1, "soft": 0.92,
+     "predicted_answer": "...", "question": "...",
+     "reference_text": item["reference_text"]},
+    {"id": "ex_002", "hard": 0, "soft": 0.13, "fail_reason": "...", ...},
+    ...
+]
+```
+
+The trainer only requires `id`, `hard`, `soft`. The rest is preserved on
+`RolloutResult.extras` (see `skillopt/types.py`) and is what your
+`reflect()` consumes via `run_minibatch_reflect`.
+
+## Step 5 — Register the adapter
+
+Edit [`scripts/train.py`](https://github.com/microsoft/SkillOpt/blob/main/scripts/train.py)
+and add to `_register_builtins()`:
+
+```python
+    try:
+        from skillopt.envs.docfaithful.adapter import DocFaithfulAdapter
+        _ENV_REGISTRY["docfaithful"] = DocFaithfulAdapter
+    except ImportError:
+        pass  # docfaithful deps not installed — skip
+```
+
+There is **no `BENCHMARK_REGISTRY` dict in `skillopt/envs/__init__.py`** —
+the registry lives in `scripts/train.py` and is populated lazily so that
+optional deps don't break `--help`.
+
+## Step 6 — Create the YAML config
+
+`configs/docfaithful/default.yaml`:
+
+```yaml
+_base_: ../_base_/default.yaml      # NOTE: string, not list
+
+model:
+  reasoning_effort: medium
+
+train:
+  batch_size: 16
+  accumulation: 1
+  num_epochs: 4
+
+gradient:
+  minibatch_size: 8
+  merge_batch_size: 8
+
+optimizer:
+  learning_rate: 4
+
+env:
+  name: docfaithful
+  # Optional: a seed skill document. Create this file (or any markdown
+  # file) yourself before the first run, or omit the key to let SkillOpt
+  # start from an empty skill.
+  skill_init: skillopt/envs/docfaithful/skills/initial.md
+  split_mode: split_dir
+  split_dir: data/docfaithful_split
+  workers: 4
+  max_completion_tokens: 4096
+  limit: 0
+```
+
+> ⚠️ `_base_` is currently parsed as a **string path**, not a list. Write
+> `_base_: ../_base_/default.yaml`, not `_base_: ['../_base_/default.yaml']`.
+> See [`skillopt/config.py`](https://github.com/microsoft/SkillOpt/blob/main/skillopt/config.py)
+> if you want to add list-form inheritance.
+
+## Step 7 — Run
+
+```bash
+# If you set skill_init above, create the seed skill first:
+#   mkdir -p skillopt/envs/docfaithful/skills
+#   echo "# DocFaithful initial skill" > skillopt/envs/docfaithful/skills/initial.md
+
+python scripts/train.py --config configs/docfaithful/default.yaml
+```
+
+If you get `ValueError: Unknown environment 'docfaithful'. Available: [...]`,
+you forgot Step 5.
+
+If you get `TypeError: Can't instantiate abstract class DocFaithfulAdapter`,
+you forgot to implement one of the five abstract methods on `EnvAdapter`:
+`build_train_env`, `build_eval_env`, `rollout`, `reflect`,
+`get_task_types`.
+
+## Tips
+
+- Start with `train.batch_size: 4` and `limit: 10` while debugging.
+- The `evaluate` half lives **inside your `rollout`**, not as a separate
+  method — there is no `evaluate()` in the `EnvAdapter` ABC. Score the
+  prediction in `run_batch` and put the score on each result dict's
+  `hard` / `soft`.
+- Noisy scoring kills the optimizer. Spend time on `run_batch`'s scoring
+  before you spend time on prompts.
+- If your benchmark needs heavy optional deps (selenium, vllm, ...),
+  wrap the registration block with `try / except ImportError` (Step 5)
+  so people without those deps can still `--help`.
+- Copy `skillopt/envs/_template/` as a starting skeleton — it now
+  implements the real abstract methods.

+# Skill Document
+
+A **skill document** is a Markdown file that serves as the "prompt weights" of your agent. SkillOpt trains this document through iterative optimization.
+
+## What is a Skill Document?
+
+A skill document is a structured set of instructions that tells a language model **how** to approach a specific type of task. It's analogous to learned weights in a neural network — encoding task-specific knowledge in natural language rather than floating-point parameters.
+
+## Structure
+
+A typical skill document contains:
+
+```markdown
+# Task Strategy
+
+## General Approach
+- Break complex problems into sub-steps
+- Always verify intermediate results
+
+## Common Patterns
+- When you see X, try approach Y
+- Avoid Z because it leads to errors
+
+## Edge Cases
+- If the input contains A, handle it specially by...
+- Watch out for B — it requires C
+
+## Output Format
+- Always include reasoning before the answer
+- Format numbers with proper units
+```
+
+## How It Evolves
+
+During training, the skill document is modified by **edit patches**:
+
+1. **Additions**: New rules or strategies discovered from failed trajectories
+2. **Modifications**: Refining existing rules that are partially correct
+3. **Deletions**: Removing rules that consistently lead to errors
+
+Each edit is validated through the **gate** mechanism before being permanently accepted.
+
+## Initial Skill
+
+You can start training with:
+
+- **Empty skill**: The system learns everything from scratch
+- **Seed skill**: Provide initial instructions to bootstrap training
+- **Pre-trained skill**: Transfer a skill from a related benchmark
+
+Configure the initial skill in your YAML:
+
+```yaml
+train:
+  init_skill: "path/to/initial_skill.md"  # or omit for empty
+```
+
+## Skill Quality Metrics
+
+Track your skill's evolution through:
+
+- **Validation score**: Primary metric on the selection split
+- **Test score**: Final metric on held-out test data
+- **Skill length**: Total tokens in the document
+- **Edit acceptance rate**: Fraction of proposed edits that pass gating
+
+## Best Practices
+
+!!! tip "Tips for better skills"
+    1. **Start with a seed skill** (`env.skill_init`) if you have domain knowledge — it converges faster
+    2. **Use cosine LR schedule** — aggressive early exploration + careful late refinement
+    3. **Enable slow update** (`use_slow_update: true`) to prevent forgetting across epochs
+    4. **Enable meta skill** (`use_meta_skill: true`) so the optimizer accumulates strategy memory

+
+## Stage Details
+
+### 1. Rollout (Forward Pass)
+
+The **target** model executes tasks using the current skill document as its prompt. Each task produces a trajectory and a score.
+
+```python
+# Analogy: forward pass through the network
+predictions = model(input, skill_document)
+scores = evaluate(predictions, ground_truth)
+```
+
+### 2. Reflect (Backward Pass)
+
+The **optimizer** model analyzes failed trajectories and produces **edit patches** — structured suggestions for improving the skill document.
+
+Two modes:
+
+- **Shallow**: Analyze each trajectory independently
+- **Deep**: Cross-reference multiple failures to find systemic issues
+
+```python
+# Analogy: computing gradients
+gradients = loss.backward()  # → edit patches
+```
+
+### 3. Aggregate
+
+Semantically similar edit patches are merged to avoid redundant edits.
+
+### 4. Select (Gradient Clipping)
+
+Edits are ranked by relevance score. The `learning_rate` parameter caps how many edits are applied per step — just like gradient clipping prevents overshooting.
+
+```python
+# Analogy: gradient clipping + optimizer step size
+selected = top_k(edits, k=learning_rate)
+```
+
+The `lr_scheduler` adjusts this over training:
+
+- **cosine**: Start aggressive, taper smoothly
+- **linear**: Linear decay
+- **constant**: Fixed rate
+
+### 5. Update (Parameter Update)
+
+Selected edits are applied to the skill document, producing a new version.
+
+### 6. Gate (Validation)
+
+The updated skill is evaluated on a **selection split** (analogous to a validation set). The update is only accepted if performance improves.
+
+## Epoch Boundary Mechanisms
+
+### Slow Update
+
+At the end of each epoch (starting from epoch 2), the system performs a **longitudinal comparison**: it rolls out both the previous epoch's skill and the current skill on the same samples, categorizes items as improved/regressed/persistent_fail/stable_success, then generates high-level **guidance** that is injected into the skill document. This prevents catastrophic forgetting of earlier improvements.
+
+### Meta Skill
+
+A **meta-skill memory** accumulates high-level strategy notes across the entire training run. At the end of each epoch, the optimizer reflects on what changed between epochs and produces a compact memory that is provided as additional context during future reflection steps.

+      <h2>1.1 What is SkillOpt <a class="anchor" href="#what-is">#</a></h2>
+      <p><strong>SkillOpt</strong> is a text-space optimizer that improves a <em>frozen</em> language agent by iteratively editing a natural-language <strong>skill document</strong> — never the model weights. The skill document is a Markdown file that conditions a target model as it executes tasks. SkillOpt treats this document as the "weights" and runs a training loop that mirrors deep-learning training: rollout (forward pass), reflect (backward pass / gradients), select &amp; apply edits (optimizer step), and a validation gate (accept/reject).</p>
+      <p>Two roles split every model call:</p>
+      <ul>
+        <li><strong>Target</strong> — executes tasks using the current skill document (the agent being improved).</li>
+        <li><strong>Optimizer</strong> — analyzes the target's trajectories and proposes edits to the skill document.</li>
+      </ul>
+      <p>The same loop drives six benchmarks out of the box (QA, document QA, embodied agents, math, spreadsheet code generation, and tool-augmented QA).</p>

+        <p>Cosine schedule tends to beat constant; moderate learning rates (≈4–16 edits/step) beat very high/low; slow update curbs cross-epoch forgetting; meta-skill memory improves reflection quality. Conversely, bigger rollout batches and many epochs show diminishing returns — skills converge in ~2–4 epochs.</p>

+      lightweight <em>ID manifests</em> under <code>data/</code>. The manifests
+      pin exactly which examples each split uses but do <strong>not</strong>
+      contain the example contents — so you materialize the data once before
+      the first run.</p>
+      <p><strong>Step 1 — materialize the SearchQA splits</strong> (one-time; downloads the ~6.5&nbsp;GB source dataset). The manifest IDs match the <code>key</code> field of the
+      <a href="https://huggingface.co/datasets/lucadiliello/searchqa">lucadiliello/searchqa</a>
+      dataset:</p>

+      <p>To sanity-check your setup <em>without</em> training, evaluate a

+## Deep Learning Analogy
+
+SkillOpt brings the familiar deep-learning training paradigm to agentic prompt optimization:
+
+| Deep Learning | SkillOpt | 
+|---|---|
+| Model weights | Skill document (Markdown) |
+| Forward pass | Rollout (target executes tasks) |
+| Loss / gradient | Reflect (optimizer produces edit patches) |
+| Gradient clipping | Edit selection (`learning_rate` = max edits) |
+| SGD step | Patch application to skill |
+| Validation set | Gated evaluation on selection split |
+| LR schedule | `lr_scheduler`: cosine, linear, constant |
+| Epochs | Multi-epoch with slow update & meta skill memory |
+
+---
+
+## Supported Benchmarks
+
+| Benchmark | Type | Config |
+|---|---|---|
+| **DocVQA** | Document QA | `configs/docvqa/` |
+| **ALFWorld** | Embodied AI | `configs/alfworld/` |

+

+framework** with new environments / benchmarks. For ready-made adapters,
+browse [`skillopt/envs/`](https://github.com/microsoft/SkillOpt/tree/main/skillopt/envs).
+
+> **Source of truth.** The classes below are real Python ABCs defined in
+> `skillopt/envs/base.py`, `skillopt/datasets/base.py`, `skillopt/types.py`,
+> and `skillopt/evaluation/gate.py`. If this page ever drifts, the code
+> wins — please open an issue.
+
+---
+
+## Core Classes
+
+### `EnvAdapter`
+
+`skillopt/envs/base.py` — abstract adapter that connects the SkillOpt
+trainer to an environment (benchmark, simulator, REST API, ...).
+Subclasses **must** implement the five abstract methods below.
+
+```python
+from abc import ABC, abstractmethod
+from skillopt.datasets.base import BaseDataLoader, BatchSpec
+
+class EnvAdapter(ABC):
+
+    # ── Lifecycle hooks (have defaults; override only if needed) ────────
+
+    def setup(self, cfg: dict) -> None: ...
+    def get_dataloader(self) -> BaseDataLoader | None: ...
+    def requires_ray(self) -> bool: ...                 # default False
+
+    # ── Abstract methods (subclasses MUST implement) ────────────────────
+
+    @abstractmethod
+    def build_train_env(self, batch_size: int, seed: int, **kwargs):
+        """Return an environment-manager object to be passed to rollout()."""
+
+    @abstractmethod
+    def build_eval_env(self, env_num: int, split: str, seed: int, **kwargs):
+        """Like build_train_env() but for a fixed eval split."""
+
+    @abstractmethod
+    def rollout(self, env_manager, skill_content: str,
+                out_dir: str, **kwargs) -> list[dict]:
+        """Run a batch of episodes with the current skill.
+
+        Each returned dict MUST contain:
+          - "id":   str        episode/task identifier
+          - "hard": int (0|1)  pass/fail (may be float 0.0-1.0 if smoothed)
+          - "soft": float      partial-credit score in [0.0, 1.0]
+        It MAY contain env-specific extra keys (parsed into RolloutResult.extras).
+        """
+
+    @abstractmethod
+    def reflect(self, results: list[dict], skill_content: str,
+                out_dir: str, **kwargs) -> list[dict | None]:
+        """Turn rollout results into a list of raw patch dicts.
+
+        Each dict (or None to drop the slot) MUST contain:
+          - "patch":       {"edits": [...]}     a Patch.to_dict() payload
+          - "source_type": "failure" | "success"
+        """
+
+    @abstractmethod
+    def get_task_types(self) -> list[str]:
+        """Distinct task-type strings used for stratified sampling."""
+```
+
+The trainer also calls a few default-implemented helpers on every adapter:
+`build_reference_text`, `get_reference_metadata`, `attach_reference_context`,
+`select_representative_items`, and `build_env_from_batch`. Read the docstrings
+in `skillopt/envs/base.py` if you need to override any of these — most
+benchmarks don't.
+
+### `BaseDataLoader` / `SplitDataLoader`
+
+`skillopt/datasets/base.py` — episode-planning loaders.
+
+```python
+class BaseDataLoader(ABC):
+    def setup(self, cfg: dict) -> None: ...
+    @abstractmethod
+    def build_train_batch(self, batch_size: int, seed: int, **kwargs) -> BatchSpec: ...
+    @abstractmethod
+    def build_eval_batch(self, env_num: int, split: str, seed: int, **kwargs) -> BatchSpec: ...
+
+class SplitDataLoader(BaseDataLoader):
+    """Concrete base for dataset-backed envs with on-disk train/val/test splits.
+
+    Subclasses only need to implement load_split_items() (and optionally
+    load_raw_items() if you also want ``split_mode='ratio'``).
+    """
+    def load_split_items(self, split_path: str) -> list[dict]: ...
+    def load_raw_items(self, data_path: str) -> list[dict]: ...   # optional
+```
+
+`SplitDataLoader` handles two layout modes:
+
+| `split_mode` | What it expects |
+|---|---|
+| `"split_dir"` | A directory with `train/`, `val/`, `test/` subdirs already split. |
+| `"ratio"` | A raw dataset path + `split_ratio: "2:1:7"` style string. |
+
+In either case the items returned by `load_split_items()` are plain
+`dict` objects with at minimum an `"id"` key.
+
+### `BatchSpec`
+
+`skillopt/datasets/base.py` — a slotted dataclass describing one batch
+request the trainer hands to the adapter.
+
+```python
+@dataclass(slots=True)
+class BatchSpec:
+    phase: str                 # "train" | "eval"
+    split: str                 # "train" | "val" | "test" | "valid_seen" | ...
+    seed: int
+    batch_size: int
+    payload: object | None = None     # what the loader produced (e.g. list[dict])
+    metadata: dict = field(default_factory=dict)
+```
+
+### `Edit` / `Patch`
+
+`skillopt/types.py` — the I/O types Reflect / Aggregate / Update produce
+and consume.
+
+```python
+EditOp = Literal["append", "insert_after", "replace", "delete"]
+
+@dataclass
+class Edit:
+    op: EditOp
+    content: str = ""
+    target: str = ""
+    support_count: int | None = None
+    source_type: Literal["failure", "success"] | None = None
+    merge_level: int | None = None
+    update_origin: str = ""
+    update_target: str = ""
+
+@dataclass
+class Patch:
+    edits: list[Edit] = field(default_factory=list)
+    reasoning: str = ""
+    ranking_details: dict[str, Any] | None = None
+```
+
+Both types support `to_dict()` / `from_dict()` for serialization.
+
+### `RolloutResult`
+
+`skillopt/types.py` — the normalised rollout return type. The trainer
+calls `RolloutResult.from_dict(...)` on each dict returned from
+`EnvAdapter.rollout()`, so the only **hard** requirement on those dicts is
+the three keys above (`id`, `hard`, `soft`). Extra fields are preserved
+into `RolloutResult.extras`.
+
+### `GateResult` / `GateAction`
+
+`skillopt/evaluation/gate.py` — the validation-gate decision types
+returned each epoch.
+
+---
+
+## Registering an environment
+
+Environments are not registered via decorators or a `BENCHMARK_REGISTRY`
+dict. The trainer keeps a lazy registry inside `scripts/train.py` —
+`_ENV_REGISTRY` — populated by `_register_builtins()`. To add a new env
+you append a `try / except ImportError` block there. See
+[Add a New Benchmark](../guide/new-benchmark.md) for the full step-by-step.
+
+---
+
+## Backends (model layer)
+
+The model layer lives under `skillopt.model.*`. Backends are selected
+via `model.optimizer_backend` and `model.target_backend` in the config —
+not via a base class subclass. Supported values (as of this writing):
+
+| Backend | Optimizer? | Target? |
+|---|---|---|
+| `openai_chat` | ✓ | ✓ |
+| `claude_chat` | ✓ | ✓ |
+| `qwen_chat` | ✓ | ✓ |
+| `minimax_chat` | ✓ | ✓ |
+| `codex_exec` | — | ✓ |
+| `claude_code_exec` | — | ✓ |
+
+See `skillopt/model/backend_config.py` for the live whitelist and
+[`docs/reference/config.md`](./config.md) for the per-backend
+configuration keys.

+# SkillOpt-Sleep — controllable dreaming architecture
+
+The sleep engine is no longer a single fixed pipeline. It is a controllable
+offline "dream / imagination" loop the user steers. This documents the knobs
+added in the four-stage refactor and how they map to the user's design.
+
+## The mental model
+
+> Sleep = an offline imagination rollout. Re-run the user's real
+> tasks (and dream-augmented variants) many times, look at what went well vs
+> badly, distil durable rules, and keep only what survives a real-task check —
+> unless the user opts out of that check.
+
+## 1. Data splits — train (dream) / val (real) / test (real)
+
+The anti-overfitting foundation:
+
+| Split | Source | Role |
+|---|---|---|
+| **train** | real tasks **+ dream-augmented** variants | drives reflection (the imagination pool — over-dreaming is fine) |
+| **val** | **real only**, disjoint from test | gates updates (prevents overfitting) |
+| **test** | **real only**, disjoint from val | the final held-out measure, kept close to real usage |
+
+Hard guarantee (unit-tested): a task with `origin='dream'` **never** lands in
+val or test. `assign_splits(val_fraction, test_fraction)` does the deterministic
+3-way split; gbrain's own held-out maps to our `test`.
+
+## 2. The validation gate is optional
+
+`--gate on` (default): an edit is accepted only if it strictly improves the
+**val** score — the SkillOpt discipline that blocks regressions and reward
+hacking.
+
+`--gate off`: greedy. Edits are kept without the hard val-improvement
+requirement (the user decides they don't want hard filtering), but val/test
+movement is still reported (`greedy_improved` / `greedy_regressed` /
+`greedy_flat`) so nothing is hidden.
+
+## 3. Slow-update — long-term memory, gate-independent
+
+Even with the gate off, the engine runs a **slow-update** at the end of the
+nights: it compares behaviour under the first-night vs final skill across the
+val tasks and distils durable longitudinal guidance into a **protected field**
+(`<!-- SLOW_UPDATE_START --> … <!-- SLOW_UPDATE_END -->`, the same markers as
+the main SkillOpt repo). Step-level edits never touch this field. This is the
+"short-term experience → long-term memory" consolidation; turning the gate off
+does not cost you long-term memory.
+
+## 4. Budget — the user picks the spend
+
+`--budget-tokens N` / `--budget-minutes M`: the engine auto-plans depth
+(`nights × rollouts_per_task`) to fit the budget (`plan_depth`). Stops cleanly
+when exhausted and logs what it skipped — no silent truncation. The whole thing
+is offline imagination on the user's own quota.
+
+## 5. Multi-rollout contrastive reflection — the imagination core
+
+`--rollouts-k K` (K>1): each train task is rolled out K times. The optimizer is
+shown the **high-scoring vs low-scoring** attempts of the same task and asked
+what the good ones did that the bad ones didn't, distilling a general rule. This
+is a far stronger signal than a single failure, and it is exactly the user's
+"run it many times, learn from the contrast" idea. Tasks with the highest score
+*spread* (some passed, some failed) are the most informative and are prioritised.
+
+## 6. Multi-objective reward — accuracy ↑, tokens ↓, latency ↓
+
+Every rollout records its `tokens` and `latency_ms`.
+`multi_objective_reward(w_acc, w_tokens, w_latency)` is a weighted reward so a
+skill can be optimised to be **cheaper and faster**, not only more accurate
+(cost terms normalised against a reference; default weights = accuracy-only, so
+existing behaviour is unchanged). This turns "gets better the more you use it"
+into "more accurate, cheaper, and faster the more you use it".
+
+## 7. User preferences as a prior
+
+`--preferences "<free text>"`: injected into the optimizer's reflect prompt as a
+prior (set on the optimizer model for dual backends), so the user's stated
+preferences steer what rules get written.
+
+## How the knobs compose (one command)
+
+```bash
+python -m skillopt.sleep.experiments.run_gbrain \
+  --optimizer-backend claude --optimizer-model sonnet \   # strong optimizer
+  --target-backend claude --target-model haiku \          # cheap target (transfer)
+  --seeds thorough-analyst \
+  --gate on \                                              # or off for greedy
+  --rollouts-k 2 \                                         # contrastive imagination
+  --budget-tokens 60000 \                                  # auto-plan depth
+  --preferences "Prefer concise, British English." \       # prior
+  --nights 3
+```
+
+All of this is exercised by the deterministic test suite (29 tests) and
+validated on real Claude + Codex (see `real_api_results.md` / `FINAL_REPORT.md`).
+
+## Real cross-validation of the new features (Claude ⟷ Codex)
+
+Three live runs exercised the new code paths on both runtimes (raw logs under
+`docs/sleep/raw/crosscheck_*.txt`):
+
+| # | Config | What it proves | Result |
+|---|---|---|---|
+| **A** | Claude Sonnet→Haiku, **gate=off**, **rollouts_k=2** | greedy mode + multi-rollout + 3-way split (val & test both reported) | brief-writer **test 0→1.00**, action `greedy_improved`, val=1.0 test=1.0 |
+| **B** | **Codex**, gate=on, **rollouts_k=2** | new paths on the other runtime | brief-writer **test 0→1.00**, 2-night `accept_new_best`, val+test reported |
+| **C** | Claude Sonnet→Haiku, thorough-analyst, 3 nights | **slow-update** long-term memory fires | test 0→0.33 (val gate holds nights 2–3) and the slow-update distilled a durable meta-rule |
+
+The slow-update guidance C produced is the kind of cross-night lesson the field
+is for — note it is general, not task-specific:
+
+> *"On character-constrained tasks (≤1200 chars), plan structure before writing:
+> allocate space per point explicitly and cut until the outline fits, then fill —
+> never draft freely and trim after."*
+
+Takeaways confirmed live: the **gate-off greedy path**, the **3-way val/test
+split**, **multi-rollout** on both runtimes, and the **gate-independent
+slow-update** all work with real models on both Claude and Codex.

+> reviewing past sessions, replaying tasks, and consolidating validated memory +
+> skills behind a held-out gate. Every real-model result here was run on **both
+> Claude and Codex**, including the honest failures and the bugs they exposed.
+
+**Date:** 2026-06-07 · **Branch:** `feat/claude-code-sleep-plugin`
+**Benchmark:** [gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1`
+(the same public suite gbrain scores its own optimizer against).
+**Protocol:** a deliberately deficient skill → 1–2 offline "nights" (replay →
+reflect → bounded **gated** edit) → score the **held-out** task set (never
+optimized against). Held-out scoring uses a local rule judge — the optimizer
+never grades itself.
+
+---
+
+## 1. Headline — clean, all green (full gbrain parity)
+
+**Strong optimizer (Claude Sonnet 4.6) → weak target (Claude Haiku 4.5)**, fully
+isolated calls, 3 held-out tasks/seed. All **4** gbrain `skillopt-v1` seeds —
+matching gbrain's own scorecard coverage:
+
+| Optimizer → Target | Seed | Flaw | Held-out before → after | Nights |
+|---|---|---|---|---|
+| Sonnet → Haiku | brief-writer | missing structure | **0.00 → 1.00** | 1 |
+| Sonnet → Haiku | advisor | no verdict | **0.00 → 1.00** | 1 |
+| Sonnet → Haiku | thorough-analyst | no length discipline | **0.00 → 1.00** | 2 |
+| Sonnet → Haiku | quick-answerer | never uses tools | **0.00 → 1.00** | 1 |
+| Codex → Codex (gpt-5.5) | brief-writer | missing structure | **0.00 → 1.00** | 2 |
+| Codex → Codex (gpt-5.5) | advisor | no verdict | **0.00 → 1.00** | 2 |
+
+**4/4 Claude seeds reach a perfect held-out score** (gbrain's headline is the same
+4/4 0→1.00), plus Codex on the text seeds. Every change is gated and staged.
+
+The `quick-answerer` seed is judged by **real tool use** (`tool_called: search`):
+the deficient skill says *"never look anything up — answer from memory"*; the
+optimizer wrote an OVERRIDE rule, and the Haiku target **genuinely invoked a
+`./search` shell tool** (detected from the tool's own log, not self-reported) →
+held-out 1.00. The thorough-analyst run shows textbook **2-night convergence**
+(0.33 → 1.00).
+
+---
+
+## 2. The finding that matters most: the optimizer model is decisive
+
+This is the direct answer to "let me specify the optimizer and target separately,
+and watch the skill." It matters a lot:
+
+| Optimizer | Target | brief-writer | advisor | thorough-analyst |
+|---|---|---|---|---|
+| **Haiku** (weak) | Haiku | 1.00 *or* 0.00 (flaky) | 1.00 | 0.33 |
+| **Sonnet** (strong) | Haiku | **1.00** | **1.00** | **1.00** |
+
+A weak self-optimizing model (Haiku proposing its own edits) is **unreliable** —
+it intermittently emits non-JSON and wastes a night, so the same seed scores 1.00
+on one run and 0.00 on another. A **strong optimizer** (Sonnet) reliably produces
+clean, concrete edit rules and lifts every seed to 1.00. This is exactly the
+SkillOpt design (strong optimizer, frozen target) and the reason the
+optimizer/target split is a first-class feature here.
+
+**Practical guidance baked into the plugin:** default to a strong optimizer; the
+sweep's `direct` plan now uses Sonnet→Haiku.
+
+---
+
+## 3. Two real bugs we found by running against live models
+
+Per gbrain's own lesson ("the bugs that matter only show up when the whole thing
+actually runs"), the first live runs surfaced two real defects. Both are fixed.
+
+1. **Ambient-context leak (Claude).** `claude -p` was injecting the user's
+   *global* skills + project `CLAUDE.md` into every optimizer/target call — one
+   reflect call literally returned a 21 KB list of the machine's installed skills
+   instead of JSON edits, so the night produced no edits and the gate rejected.
+   Some early Claude "successes" were partly leak-assisted. **Fix:** run isolated
+   — `--bare --disable-slash-commands --disallowedTools '*'
+   --exclude-dynamic-system-prompt-sections`, clean temp cwd. (Codex was never
+   affected; the real `@openai/codex` binary runs in its own clean context.)
+
+2. **Wasted nights on transient non-JSON.** A single malformed reply zeroed a
+   night. **Fix:** `reflect()` retries once with a firmer "JSON only" instruction.
+
+We report these because a tool people build on has to be honest about where it was
+weak and what changed.
+
+---
+
+## 4. Cross-model transfer (the price-difference value prop)
+
+> *Optimize cheap overnight, deploy anywhere.* A skill is just text, so a good
+> rewrite should help a model it was never optimized on.
+
+Optimize on SOURCE, **freeze** the learned skill, evaluate held-out on TARGET with
+no further optimization. All four pairs are positive — including **across
+runtimes** (Codex ↔ Claude):
+
+| Source (optimizer) | Target (deploy) | Seed | Target baseline → transferred | Gain |
+|---|---|---|---|---|
+| Claude Haiku (cheap) | Claude Sonnet (expensive) | brief-writer | 0.00 → **1.00** | +1.00 |
+| Claude Sonnet | Claude Haiku | brief-writer | 0.00 → **1.00** | +1.00 |
+| **Codex** | **Claude Haiku** | brief-writer | 0.00 → **1.00** | +1.00 |
+| **Claude Haiku** | **Codex** | brief-writer | 0.00 → **1.00** | +1.00 |
+
+**4/4 transfers positive.** A skill optimized on a cheap model deploys for free on
+an expensive one, and skills move between Codex and Claude — the Sleep-setting
+analogue of SkillOpt's cross-model and cross-harness transfer tables. This is the
+quantified answer to "optimize cheap overnight, deploy anywhere."

+Full machine-generated scorecard: [`benchmark_report.md`](benchmark_report.md)
+(source data `sweep.jsonl`).

+## 6. Honest limitations
+
+- **Latency:** each CLI call is ~14–15 s startup-dominated, so runs are capped at
+  a few tasks/nights. Fine for nightly cron; we note it plainly.
+- **Weak optimizers are flaky:** use a strong optimizer model (§2).
+- **Tool-use seed covered honestly:** `quick-answerer` (`tool_called: search`)
+  runs a real tool loop — a callable `./search` shim, detected from its log.
+  Deeper multi-tool / multi-turn workflows are future work.
+- **Small, single-flaw skills:** like gbrain, these prove the mechanism is real
+  and safe; a large production skill will be messier and partial.

+TITLE:
+Add SkillOpt-Sleep: nightly offline self-evolution plugins (Claude Code, Codex, Copilot)
+
+BODY:
+## Summary
+
+Adds **SkillOpt-Sleep** — a nightly offline "sleep cycle" that gives a local
+coding agent the deployment-time analogue of training: it reviews past sessions,
+replays recurring tasks on the user's own API budget, and consolidates what it
+learns into **validated** long-term memory and skills behind a held-out gate.
+Synthesizes SkillOpt (validation-gated bounded text edits), Claude Dreams
+(offline consolidation; review-then-adopt), and the agent-sleep idea
+(short-term experience -> long-term competence).
+
+Shipped as plugins for **three agents**, one engine + three thin shells:
+
+- **Claude Code** — `.claude-plugin` + `/sleep` command + skill + hooks
+- **Codex** — `~/.codex/prompts/sleep.md` + `~/.agents/skills` + `install.sh`
+- **Copilot** — a stdlib-only MCP server exposing `sleep_*` tools
+
+## Design notes
+
+- **Open-source tool, decoupled from the research code.** The engine lives in the
+  new top-level `skillopt_sleep/` package with **zero dependency** on the paper's
+  `skillopt/` experiment package (the validation gate is vendored).
+- Controllable: optional gate (`--gate on|off`), train(dream)/val(real)/test(real)
+  splits, slow-update long-term memory, token/time budget, multi-rollout
+  contrastive reflection, multi-objective reward (accuracy/tokens/latency), user
+  preferences, and separate optimizer/target models.
+
+## Validation (real models)
+
+On the public [gbrain-evals](https://github.com/garrytan/gbrain-evals)
+`skillopt-v1` benchmark, deficient skills go **0.00 -> 1.00** on held-out sets
+with **both Claude and Codex** (all 4 seeds, including a real tool-use loop);
+cross-model transfer is positive; the gate blocks regressions. Independently
+load-tested on a fresh non-benchmark persona ("SQL must always include LIMIT"):
+held-out test **0.00 -> 1.00** on both backends. See `docs/sleep/FINAL_REPORT.md`
+and `docs/sleep/plugin_load_test.md`.
+
+## Tests
+
+- 29 deterministic unit tests (`tests/test_sleep_engine.py`), no API key required.
+- `python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves`
+  proves held-out lift and that the gate blocks a harmful edit.
+
+## Test plan
+
+- [ ] `python -m unittest tests.test_sleep_engine` (29 pass)
+- [ ] `python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves`
+- [ ] Claude Code: `/plugin marketplace add ./plugins/claude-code` -> `/sleep status`
+- [ ] Codex: `bash plugins/codex/install.sh`
+- [ ] Copilot: MCP server `tools/list` returns the `sleep_*` tools

+
+## The fresh persona
+
+A data analyst whose SQL queries must always include a `LIMIT` clause — built
+from scratch for this test. Two forms were used:
+
+1. **Real transcripts** — crafted Claude Code session JSONL where the analyst
+   asks for SQL, the agent forgets `LIMIT`, and the user complains ("you forgot
+   a LIMIT again", "always cap results"). This exercises the real
+   harvest → mine pipeline.
+2. **Checkable tasks** — the same intent with a rule judge
+   (`regex: (?i)LIMIT\s+100`), so the optimizer can be scored on whether future
+   SQL follows the house rule.

+| **Claude Code** (`scripts/sleep.sh`) | `harvest`, full `run`, `adopt` | harvest found 2 sessions → 2 tasks; `run` staged a proposal; `adopt` honored the safety contract (no live change when nothing was accepted) |
+| **Codex** (`install.sh` + shared runner) | `install.sh` into a temp HOME | placed `~/.codex/prompts/sleep.md` and `~/.agents/skills/skillopt-sleep/SKILL.md` correctly |
+| **Copilot** (`mcp_server.py`) | `initialize` → `tools/list` → `tools/call sleep_harvest` | 5 tools listed; `sleep_harvest` returned real engine output (2 sessions → 2 tasks) |
+
+### Genuine improvement (real model, fresh persona)
+
+Optimizer **Claude Sonnet 4.6** → target **Claude Haiku 4.5**, 3-way split
+(5 train / 2 val / 5 test), scored on the held-out **test** queries; and the same
+fresh persona self-optimized on **Codex**:
+
+| Backend | Held-out **test** (fraction of SQL with `LIMIT 100`) before → after |
+|---|---|
+| Claude (Sonnet → Haiku) | **0.00 → 1.00** |
+| Codex | **0.00 → 1.00** |
+
+In one night each optimizer wrote, into the protected learned block, a rule like:
+
+> *"OVERRIDE: Every SQL query you generate MUST include `LIMIT 100` …"* (Claude)
+> *"Hard requirement: every SQL query response must include …"* (Codex)
+
+and the target then applied it to the **unseen** test queries. This is the whole
+claim on a task family the engine had never seen: it learned the user's house
+rule from their failures and generalized it — confirmed on both backends.
+
+## An honest finding from load-testing
+
+The **first** attempt used `val_fraction=0.34, test_fraction=0.34`, which left
+only **1 train task** for an 8-task set — too little signal — so reflect produced
+nothing and the night was a no-op (val already 0.75). Re-balancing the split to a
+real train pool (5 train) fixed it and produced the 0 → 1.00 result above. This
+is exactly the kind of issue that only surfaces when you actually run the thing,
+and it motivates a future guardrail: warn when the train pool is too small for
+the chosen split fractions.
+
+## Reproduce
+
+The checkable persona run (real Claude):
+
+```python
+# see the snippet in docs/sleep/plugin_load_test.md history, or run:
+python -m skillopt_sleep.experiments.run_experiment --persona programmer --assert-improves  # deterministic
+```
+
+Shell checks:
+
+```bash
+# Copilot MCP server
+printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
+  | SKILLOPT_SLEEP_REPO="$(pwd)" python3 plugins/copilot/mcp_server.py
+# Codex installer (into a throwaway HOME)
+HOME=$(mktemp -d) bash plugins/codex/install.sh
+```

+# SkillOpt-Sleep — REAL API results (Claude + Codex)
+
+**Date:** 2026-06-07 (autonomous offline session)
+**Benchmark:** [gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1` —
+the same public suite gbrain publishes its own SkillOpt scorecard against
+([docs/benchmarks/2026-06-03-skillopt.md](https://github.com/garrytan/gbrain-evals/blob/main/docs/benchmarks/2026-06-03-skillopt.md)).
+
+These are **real model runs**, not the deterministic mock. The agent's
+`attempt` (and the optimizer's `reflect`) call live models via the `claude`
+and `codex` CLIs. Held-out scoring is done **locally** by the rule judge
+(`skillopt/sleep/judges.py`), so no judge-API spend and no way for the
+optimizer to grade its own homework.
+
+## Headline
+
+| Backend | Seed | Held-out before | Held-out after | Nights | Tokens |
+|---|---|---|---|---|---|
+| **Claude (Haiku 4.5)** | brief-writer | **0.00** | **1.00** | 1 | ~6.7k |
+| **Codex (default)** | brief-writer | **0.00** | **0.67** | 1 | ~5.1k |
+| **Codex (directive prompt)** | brief-writer | **0.00** | **1.00** | 2 | ~10k |
+
+Both backends took a **deliberately deficient** skill (a brief-writer with no
+risks section and no confidence level) and, within 1–2 sleep nights, proposed
+gated edits that lifted the held-out score to perfect. The edits went into the
+protected `SKILLOPT-SLEEP:LEARNED` block; nothing else in the skill was touched.
+
+This reproduces gbrain's published `0 → 1.00` headline with **our** engine and
+shows it works across **two different agent runtimes** — the core of the
+"Claude now, Codex next" plan.
+
+### The multi-night convergence (Codex, why it matters)
+
+The 2-night Codex run is the most informative trace in this whole exercise:
+
+- **Night 1** — added two precise rules (a `Key Risks` section, a `Confidence:`
+  line). Held-out still **0.00**: the rules were right but the agent, told to
+  keep briefs short, was *dropping* them under length pressure.
+- **Night 2** — the optimizer diagnosed its own residual failure and added a
+  meta-rule: *"Preserve required sections even when keeping the brief short;
+  shorten the analysis before omitting Key Risks or Confidence."* Held-out → **1.00**.
+
+That second edit is not pattern-matching a checklist — it is reasoning about
+*why the previous night underperformed*. This is exactly the iterative,
+slow-update behavior SkillOpt's design predicts, and it is the strongest
+argument for the sleep **loop** over a one-shot rewrite.
+
+## What the optimizer actually wrote
+
+**Claude** synthesized a full format template:
+
+```
+**Recommendation:** [Clear yes/no or specific answer]
+**Rationale:** [2-3 bullet points supporting the answer]
+**Key Risks:** [Downsides, edge cases, or assumptions that could invalidate this]
+**Confidence:** [High/Medium/Low] — [Why]
+```
+
+**Codex** wrote a terser rule:
+
+```
+For every brief, include a `Key Risks` section and end with
+`Confidence: Low|Medium|High`.
+```
+
+Both are correct, general, reusable rules (not task-specific answers). Claude's
+fuller template made the agent satisfy the checks on **3/3** held-out items;
+Codex's terser rule landed **2/3** — the missing item is a consistency miss the
+agent would likely fix with one more night (see "Honest notes").
+
+## How to reproduce
+
+```bash
+# clone the benchmark data
+git clone https://github.com/garrytan/gbrain-evals /tmp/gbrain-evals
+
+cd <repo>/SkillOpt-sleep   # this worktree
+
+# Claude backend
+python3.12 -m skillopt.sleep.experiments.run_gbrain \
+  --backend claude --model haiku --seeds brief-writer \
+  --data-root /tmp/gbrain-evals/eval/data/skillopt-v1 \
+  --nights 1 --limit-replay 3 --limit-holdout 3 --json
+
+# Codex backend (auto-detects the real @openai/codex binary, not the wrapper)
+python3.12 -m skillopt.sleep.experiments.run_gbrain \
+  --backend codex --seeds brief-writer \
+  --data-root /tmp/gbrain-evals/eval/data/skillopt-v1 \
+  --nights 1 --limit-replay 3 --limit-holdout 3 --json
+```
+
+## Honest notes (in the spirit of gbrain's own scorecard)
+
+- **Latency:** each CLI call is ~14–15 s of startup-dominated wall time, so runs
+  were capped at 3 train + 3 held-out tasks and 1 night to keep them ~2.5 min.
+  The response cache makes re-scoring an unchanged (skill, memory) free.
+- **Codex 0.67, not 1.00:** a single terse edit + single night under-shoots on
+  one held-out item. Two improvements (below) are expected to close it. We report
+  the 0.67, we don't dress it up.
+- **3 of gbrain's 4 seeds are scored with zero API beyond `attempt`:**
+  `section_present`, `regex`, `max_chars` are pure-text checks. Only the
+  `quick-answerer` seed (`tool_called: search`) needs a real tool loop, which is
+  Phase-3 `fresh` replay.
+- **The gate is real:** every accepted edit had to beat the held-out score; a
+  no-op night is rejected and the skill is left unchanged.
+
+## Improvements this run motivated (applied + verified)
+
+1. **A more directive `reflect` prompt** that aggregates the *exact* failing
+   judge criteria and tells the optimizer to satisfy every one (gbrain's lesson:
+   "the optimizer was never told what the scorer rewards"). Applied in
+   `skillopt/sleep/backend.py`. **Verified**: lifted Codex from 0.67 → 1.00.
+2. **Multi-night convergence** — a terse first edit gets a sharper second pass;
+   the night-2 trace above shows the optimizer self-correcting. Recommend
+   `nights >= 2` for real backends.

+# SkillOpt Sleep — Claude Code self-evolving plugin (design)
+
+**Status:** approved-for-build (autonomous offline session, 2026-06-07)
+**Author:** generated for Yifan Yang, executed autonomously while user is asleep
+**Branch:** `feat/claude-code-sleep-plugin` (worktree `my_repo/SkillOpt-sleep`)
+
+---
+
+## 1. One-paragraph summary
+
+`skillopt-sleep` is a Claude Code plugin that gives a user's local Claude
+agent a nightly **sleep cycle**. While the user is offline, it (1) **harvests**
+the day's real Claude Code session transcripts from `~/.claude`, (2) **mines**
+them into discrete *task records* with checkable outcomes, (3) **replays /
+"dreams"** those tasks offline using the user's own API budget, and (4) runs
+the **SkillOpt optimizer loop** (reflect → bounded edit → held-out gate) to
+consolidate short-term experience into long-term **memory** (`CLAUDE.md`) and
+**skills** (`SKILL.md`). Only changes that pass a validation gate are kept, and
+every change is written to a **review staging area** the user approves before it
+touches live config — mirroring Claude Dream's "input store is never modified"
+safety contract. The result: an agent that measurably gets better at *this
+user's* recurring work, every night, with zero model-weight training.
+
+## 2. Why this is the right synthesis of the three ingredients
+
+| Ingredient | What we take from it | Where it lives in this design |
+|---|---|---|
+| **SkillOpt** (your paper/code) | Skill = trainable text state; bounded add/delete/replace edits under a textual learning rate; **held-out validation gate**; rejected-edit buffer; epoch-wise slow/meta update. | The `consolidate` stage *is* a single SkillOpt epoch, reusing `skillopt.optimizer.*` and `skillopt.evaluation.gate`. |
+| **Claude Dreams** | Async offline job: read a memory store + 1–100 session transcripts → emit a **new, separate** reorganized memory store (dedup / merge / resolve contradictions / surface insights). Input never mutated; output reviewed then adopted or discarded. | The `harvest` + `consolidate-memory` stages and the **staging/adopt** safety model are modeled directly on Dreams. |
+| **Agent Sleep paper** (2605.26099) | Agents need periodic offline consolidation: short-term experience buffer → synthetic replay/self-generated data → self-update; "sleep" turns episodes into durable competence. | The whole nightly schedule, the `replay` step, and the short-term→long-term framing. |
+
+The key novel claim this enables for the project (and a future paper section):
+**SkillOpt's validation-gated bounded-edit optimizer is the missing "safe
+update rule" for Dream-style memory consolidation.** Dreams reorganize memory
+but don't *prove* the reorganization helps; the Sleep paper consolidates but
+assumes weight updates. SkillOpt-Sleep consolidates **text** (memory + skills)
+and **gates each change on replayed task performance**, so nightly evolution is
+both weight-free and regression-protected.
+
+## 3. Goals / non-goals
+
+**Goals**
+1. A working Claude Code plugin: scheduled (nightly/cron) **and** user-triggered (`/sleep`).
+2. Look back over the user's real past prompts & trajectories from local `~/.claude` records.
+3. Offline "dream training": re-run mined tasks (mock-env or fresh retry) on the user's budget.
+4. Continuous evolution of **memory** (`CLAUDE.md`) and **skills** (`SKILL.md`) via the SkillOpt gate.
+5. A reproducible experiment that answers: *does the nightly loop actually improve a held-out score?*
+6. Safety: never silently overwrite user config; stage → user approves → adopt.
+
+**Non-goals (now)**
+- Codex version (explicitly deferred by user; architecture keeps it pluggable).
+- Anthropic managed Dreams API integration (we *emulate* Dreams locally; managed API is a future backend).
+- Model fine-tuning / weight updates (out of scope by design — text-only).
+- Fully unattended auto-adopt by default (opt-in; default is review-gated).
+
+## 4. The local data we read (verified on this machine)
+
+- **Prompt history:** `~/.claude/history.jsonl` — one JSON/line: `{display, pastedContents, timestamp, project}`. The cross-session list of every prompt the user typed, with project path + epoch-ms timestamp.
+- **Full transcripts:** `~/.claude/projects/<path-slug>/<sessionId>.jsonl` — one record/line. Record `type` ∈ {`user`,`assistant`,`mode`,`permission-mode`,`attachment`,`file-history-snapshot`,`last-prompt`,…}. User/assistant records carry `message` (role+content blocks), plus `cwd`, `gitBranch`, `timestamp`, `sessionId`, `version`, `userType`. ~215k transcripts present on this box.
+- **Deployment targets we may evolve:**
+  - Project memory: `<project>/CLAUDE.md` (and `~/.claude/CLAUDE.md` global).
+  - User skills: `~/.claude/skills/<name>/SKILL.md` (frontmatter: `name`, `description`, optional `allowed-tools`, `argument-hint`).
+  - Plugin skills under `~/.claude/plugins/...`.
+
+Everything stays **on-disk and local**; the only network calls are the LLM
+optimizer/replay calls the user already pays for.
+

+            └────────────────────────────────────────────────────────────────────────────────┘
+```
+
+**1. Harvest** (`harvest.py`)
+Read `history.jsonl` + per-project transcript JSONLs for a time window
+(default: since last sleep, fallback last 24–72h). Group by project (`cwd` /
+`project`). Emit normalized `SessionDigest` objects: ordered user prompts,
+assistant final texts, tool-call summary, files touched (from
+`file-history-snapshot`), git branch, errors seen, and **user-feedback signals**
+(e.g. "still broken", "that's wrong", "perfect", re-asks of the same thing).
+
+**2. Mine** (`mine.py`)
+Turn digests into `TaskRecord`s — the unit the optimizer trains on. A task is a
+self-contained intent (the user's request) plus an *outcome label* and, where
+possible, a **checkable reference**:
+- *Explicit success/failure* from feedback signals ("works now" after N retries → the early attempts are failures, the fix is the success exemplar).
+- *Self-consistency check*: re-derivable answers (math, lookups) get a reference; open-ended ones get an LLM-judge rubric instead.
+- Each TaskRecord: `{id, project, intent, context_excerpt, attempted_solution, outcome ∈ {success,fail,mixed}, reference_kind ∈ {exact, rubric, none}, reference, tags}`.
+Mining is itself an LLM call (the **miner**), prompt-tunable, with a deterministic regex/heuristic fallback for offline/no-key runs.
+
+**3. Replay / "Dream"** (`replay.py`)
+For mined tasks, re-run the intent **offline** under the *current* skill+memory
+to get a fresh trajectory & score. Two modes:
+- `mock` (default, safe): reconstruct a sandboxed prompt from the task's captured context (no live repo mutation, no network side effects) and run the target model. Deterministic, cheap, safe to run unattended.
+- `fresh` (opt-in): actually re-attempt in a throwaway git worktree of the project. Higher fidelity, heavier, never touches the user's working tree.
+Scoring: exact-match / substring for `exact` refs; LLM-judge (0–1) for `rubric` refs; this yields the `hard`/`soft` scores SkillOpt already expects.
+
+**4. Consolidate** (`consolidate.py`) — *this is one SkillOpt epoch*
+Reuse the existing optimizer pieces rather than reinventing:
+- `reflect`: partition replayed tasks into failure/success minibatches → propose add/delete/replace edits to **skill** and a parallel proposer for **memory** (`CLAUDE.md`). (Memory consolidation also does Dream-style dedup/merge/contradiction-resolution over existing `CLAUDE.md` lines.)
+- `aggregate` + `rank_and_select` under an **edit budget** (textual learning rate).
+- `apply_patch_with_report` → candidate skill / candidate memory.
+- **GATE** (`skillopt.evaluation.gate.evaluate_gate`): replay a *held-out* slice of tasks with the candidate; accept only if it strictly beats current. Rejected edits go to the rejected-edit buffer (negative feedback) exactly as in the paper.
+- A **slow/meta** pass across nights (not just within one night) carries durable, cross-session lessons — the literal "short-term experience → long-term knowledge" of the Sleep paper. Per-night state persists in `~/.skillopt-sleep/state.json`.
+
+**5. Stage** (`staging/`)
+Write `proposed_CLAUDE.md`, `proposed_SKILL.md`, a unified diff, and a
+`sleep_report.md` (what changed, why, gate deltas, token cost) into
+`<project>/.skillopt-sleep/staging/<date>/`. **Nothing live is modified.**
+
+**6. Adopt**
+`/sleep adopt` (or `auto_adopt: true` in config for power users) copies staged
+files over the live `CLAUDE.md` / `SKILL.md`, after a `git`-style backup. This
+is the only stage that mutates user-facing config, and it is explicit by default
+— the Dreams "review the output, then adopt or discard" contract.
+
+### 5.2 Components & boundaries (each independently testable)
+
+```
+skillopt/sleep/
+  __init__.py
+  types.py         # SessionDigest, TaskRecord, ReplayResult, SleepConfig, SleepReport (dataclasses)
+  harvest.py       # ~/.claude transcripts + history.jsonl  ->  list[SessionDigest]
+  mine.py          # list[SessionDigest]  ->  list[TaskRecord]   (LLM miner + heuristic fallback)
+  replay.py        # TaskRecord + skill + memory  ->  ReplayResult (hard/soft)   (mock | fresh)

+  scripts/*                       # shims that call `python -m skillopt.sleep ...`
+```
+
+**Reuse, don't fork:** `consolidate.py` calls into existing
+`skillopt.optimizer.clip.rank_and_select`, `skillopt.gradient.aggregate.merge_patches`,
+`skillopt.optimizer.skill.apply_patch_with_report`, and
+`skillopt.evaluation.gate.evaluate_gate`. The sleep layer is an **EnvAdapter-shaped
+shim** over the user's own life, not a new optimizer.
+
+### 5.3 Data flow (one task, end to end)
+
+```
+history.jsonl + <session>.jsonl
+   └─harvest→ SessionDigest{prompts, finals, tools, feedback}
+        └─mine→ TaskRecord{intent, attempted, outcome, reference}
+             └─replay(current skill+mem)→ ReplayResult{hard, soft, trajectory}
+                  └─reflect→ edits(skill), edits(memory)
+                       └─rank/clip(edit_budget)→ candidate
+                            └─GATE(replay held-out)→ accept? → staging/  → (adopt) live CLAUDE.md/SKILL.md
+```
+
+## 6. Scheduling & triggering
+
+- **Cron/scheduled:** documented `crontab` line + an optional Claude Code hook; default `0 3 * * *` (3am local; pick an off-:00 minute in practice). The engine is a plain CLI so it works under cron, systemd-timer, or the Claude Code scheduler.
+- **User-triggered:** `/sleep run` (full cycle), `/sleep dry-run` (harvest+mine+replay, no edits), `/sleep status`, `/sleep adopt`.
+- **On-session-end harvest (optional hook):** cheaply append the just-finished session to the night's buffer so the 3am run has fresh data without a full rescan.
+
+## 7. Safety model (hard requirements)
+
+1. **Never mutate live `CLAUDE.md`/`SKILL.md` except via explicit `adopt`** (or opt-in `auto_adopt`). Default = staged + reviewed (Dreams contract).
+2. **Backups:** every adopt snapshots the prior file to `staging/<date>/backup/`.
+3. **Read-only harvest:** transcripts are read, never written.
+4. **`fresh` replay runs only in throwaway worktrees**, never the user's checkout; no `rm -rf`, no force-push, network off unless `replay.network: true`.
+5. **Budget cap:** `max_tokens_per_night` + `max_tasks_per_night`; stop early when hit, log what was skipped (no silent truncation).
+6. **Secret hygiene:** redact obvious secrets from digests before they enter prompts (reuse `_redact_*` ideas from trainer).
+7. **PII/scope:** only harvest projects on an allowlist (default: the project the plugin is invoked in) or `projects: all` opt-in.
+
+## 8. Validation experiment — "does it actually improve?"
+
+A self-contained, **deterministic-by-default** experiment lives in
+`skillopt/sleep/experiments/` and is the acceptance test for the whole idea.
+
+**Setup:** a synthetic "user persona" (e.g. *researcher who keeps asking for
+arXiv-id extraction in a fixed format*, or *programmer who keeps mis-formatting
+git commit messages*). We ship 12–20 tiny tasks with **exact checkable
+references**, split into `replay` (train) and `holdout` (test).
+
+**Procedure:**
+1. Score the holdout with an **empty** skill+memory → `baseline`.
+2. Run `N` sleep nights (each: replay train slice → reflect → gated edit).
+3. Score holdout with the evolved skill+memory → `after`.
+4. Report `after − baseline`, accept/reject counts, edit count, tokens.
+
+**Two backends:**
+- `mock` (default, **no API key, fully deterministic**): a scripted optimizer that proposes the known-good rule on failure and a scripted judge. Proves the *plumbing* (harvest→mine→replay→gate→adopt) monotonically improves the score and the gate blocks regressions. This is the CI-able acceptance test.
+- `anthropic` (opt-in, uses `ANTHROPIC_API_KEY`): the real optimizer/judge, to demonstrate genuine lift on the persona tasks.
+
+**Success criteria:**
+- Mock: `after > baseline`, gate rejects an injected harmful edit, adopt+backup works, re-run is reproducible. (Hard gate in CI.)
+- Anthropic (when run): `after ≥ baseline` on holdout with ≥1 accepted, human-readable edit; documented in the wake-up report.
+
+## 9. Personas (the user's framing) → concrete recurring-task families
+
+- **Programmer:** commit-message conventions, repo-specific build/test commands, "always run X before Y", framework gotchas → consolidated into project `CLAUDE.md` + a `repo-workflow` skill.
+- **Researcher:** citation/format preferences, experiment-logging habits, paper-section style, dataset-path memory → `research-prefs` skill + memory.
+- **Finance/analyst:** report formatting, recurring data-pull recipes, terminology → `report-style` skill + memory.
+The engine is domain-agnostic; the persona only changes which tasks get mined.
+
+## 10. Phased delivery
+
+- **Phase 0 — scaffold + types + harvest** (read-only, no API). Provable on this box's real `~/.claude`.
+- **Phase 1 — mine + replay(mock) + consolidate + gate + staging**, with the **mock** optimizer backend and the deterministic experiment green. *(primary deliverable of the offline session)*
+- **Phase 2 — plugin surface** (`/sleep`, skill, hooks, plugin.json) wired to the CLI.
+- **Phase 3 — real Anthropic backend** for miner/reflect/judge + `fresh` replay in worktrees.
+- **Phase 4 — slow/meta cross-night memory**, adopt automation, multi-project, polish + docs.
+
+This session targets **Phase 0 + Phase 1 fully**, **Phase 2 scaffolded**, and the
+**deterministic experiment passing**, all committed (not pushed) for review.
+
+## 11. Open questions for the user (answer when awake)
+
+1. **Adopt policy:** keep default *review-gated*, or do you want `auto_adopt` for your own machine?
+2. **Scope:** harvest only the invoked project, or all projects in `~/.claude/projects`?
+3. **Real-API demo:** want me to spend live `ANTHROPIC_API_KEY` budget on the persona demo, or keep everything mock until you say go?
+4. **Skill target:** evolve a *new* dedicated `skillopt-sleep`-managed skill, or also edit your existing hand-written skills in `~/.claude/skills`?
+5. **Paper:** should this become a section/figure in the SkillOpt arXiv (Dream+Sleep framing as "deployment-time continual skill optimization")?

+# SkillOpt-Sleep — plugins for Claude Code, Codex, and Copilot
+
+One engine, three thin shells. **SkillOpt-Sleep** gives a local coding agent a
+nightly **sleep cycle**: it reviews your past sessions offline, replays your
+recurring tasks on your own API budget, and consolidates what it learns into
+**validated** long-term memory and skills — behind a held-out gate, staged for
+your review. Your agent gets better the more you use it, with no model-weight
+training.
+
+It synthesizes three ideas: **SkillOpt** (validation-gated bounded text
+optimization — the research in this repo), **Claude Dreams** (offline memory
+consolidation; input never mutated; review-then-adopt), and the **agent sleep**
+literature (short-term experience → long-term competence).
+
+> **This is an open-source tool, decoupled from the research code.** The engine
+> lives in the top-level [`skillopt_sleep/`](../skillopt_sleep) package and has
+> **zero dependency** on the paper's `skillopt/` experiment package (the
+> validation gate is vendored). You can ship/use it without the research stack.
+
+## The three integrations
+
+| Platform | Folder | Mechanism | Status |
+|---|---|---|---|
+| **Claude Code** | [`claude-code/`](claude-code) | `.claude-plugin` + `/sleep` command + skill + hooks | full, installable |
+| **Codex** | [`codex/`](codex) | `~/.codex/prompts/sleep.md` + `~/.agents/skills` + `AGENTS.md` | full |
+| **Copilot** | [`copilot/`](copilot) | MCP server (`sleep_*` tools) + `copilot-instructions` | full (MCP) |
+
+All three call the **same** [`plugins/run-sleep.sh`](run-sleep.sh) → `python -m
+skillopt_sleep`, so behaviour is identical everywhere. Per-platform setup is in
+each folder's README.
+
+## Quick start (Claude Code)
+
+```bash
+git clone <repo-url> && cd SkillOpt-Sleep
+# Claude Code:
+/plugin marketplace add ./plugins/claude-code
+/plugin install skillopt-sleep@skillopt-sleep
+/sleep status
+```
+Codex: `bash plugins/codex/install.sh`.
+Copilot: register `plugins/copilot/mcp_server.py` as an MCP server.
+
+## What one "night" does
+
+```
+harvest ~/.claude (or session) transcripts → mine recurring tasks → replay offline
+   → consolidate (reflect → bounded edit → GATE on real held-out tasks)
+   → stage proposal → (you) adopt
+```
+
+Nothing live changes until you adopt; every adopt backs up first.
+
+## Controls (work on all platforms)
+
+`--gate on|off` · `--rollouts-k K` (multi-rollout contrastive reflection) ·
+`--budget-tokens/--budget-minutes` · `--preferences "..."` · separate
+optimizer/target models (`--optimizer-model` / `--target-model`) · slow-update
+long-term memory. Full guide:
+[`../docs/sleep/CONTROLLABLE_DREAMING.md`](../docs/sleep/CONTROLLABLE_DREAMING.md).
+
+## Does it actually work?
+
+Validated on the public
+[gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1` benchmark
+with **real models on both Claude and Codex**: deficient skills go **0.00 →
+1.00** on held-out sets (all 4 seeds incl. a real tool-use loop), cross-model
+transfer is positive, and the gate blocks regressions. Full results:
+[`../docs/sleep/FINAL_REPORT.md`](../docs/sleep/FINAL_REPORT.md).
+
+Deterministic proof (no API key):
+```bash
+python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves

+# SkillOpt-Sleep (Claude Code plugin)
+
+> Give your local Claude agent a **sleep cycle**. Every night it reviews your
+> past sessions offline, replays your recurring tasks on your own API budget,
+> and consolidates what it learns into **validated** memory (`CLAUDE.md`) and
+> skills (`SKILL.md`). Your agent gets better the more you use it — no
+> model-weight training.
+
+SkillOpt-Sleep is the **deployment-time** companion to
+[SkillOpt](https://github.com/microsoft/SkillOpt). SkillOpt trains a skill
+offline on a benchmark; SkillOpt-Sleep applies the same discipline to *your own
+daily usage*: bounded text edits, accepted only through a held-out validation
+gate, with rejected edits kept as negative feedback.
+
+It synthesizes three ideas:
+
+| Idea | Contribution |
+|---|---|
+| **SkillOpt** | skill/memory = trainable text; bounded add/delete/replace edits; **held-out gate** keeps only changes that help. |
+| **Claude Dreams** | offline consolidation over past sessions; input never mutated; output **reviewed then adopted**. |
+| **Agent sleep** | periodic offline replay turns short-term episodes into long-term skill. |
+
+## What it does (one "night")
+
+```
+harvest ~/.claude transcripts → mine recurring tasks → replay offline
+   → consolidate (reflect → bounded edit → GATE) → stage proposal → (you) adopt
+```
+
+Nothing live is modified until **you** run `/sleep adopt` (the Dreams "review,
+then adopt or discard" contract). Every adopt backs up the prior file first.
+
+## Install
+
+**Requirements:** Python ≥ 3.10, and the `claude` CLI (and/or `codex` CLI) on PATH.
+
+```bash
+# 1) get the code (the plugin ships inside the SkillOpt repo)
+git clone https://github.com/microsoft/SkillOpt.git
+cd SkillOpt
+
+# 2) add the plugin to Claude Code as a local marketplace
+/plugin marketplace add ./skillopt-sleep-plugin
+/plugin install skillopt-sleep@skillopt-sleep
+
+# 3) verify
+/sleep status
+```
+
+The plugin's bundled runner (`scripts/sleep.sh`) auto-selects a Python ≥ 3.10
+interpreter and calls the `skillopt_sleep` engine in the repo. No `pip install`
+is required for the default `mock` backend or for `claude`/`codex` backends —
+they shell out to the CLIs you already have.
+
+## Quick start
+
+```bash
+# from inside any project you use with Claude Code:
+/sleep dry-run     # safe preview: what it would learn, no changes staged
+/sleep run         # full cycle: stages a reviewed proposal (still no live edits)
+/sleep status      # see history + the latest staged proposal
+/sleep adopt       # apply the staged proposal to CLAUDE.md / SKILL.md (with backup)
+```
+
+Or call the engine directly (Python ≥ 3.10):
+
+```bash
+python -m skillopt_sleep run --project "$(pwd)" --scope invoked --backend mock
+python -m skillopt_sleep run --project "$(pwd)" --backend claude   # real lift via Claude
+python -m skillopt_sleep run --project "$(pwd)" --backend codex    # real lift via Codex
+```
+
+Default backend is **`mock`** — deterministic, no API spend — so you can try the
+plumbing for free. Switch to `--backend claude` or `--backend codex` for genuine
+improvement on your own budget.
+
+## Does it actually improve? (real models, public benchmark)
+
+SkillOpt-Sleep is validated against [gbrain-evals](https://github.com/garrytan/gbrain-evals)'
+public `skillopt-v1` suite — the same benchmark gbrain scores its own skill
+optimizer against. We take a deliberately **deficient** skill and run one sleep
+night; held-out scoring is done by a local rule judge (no judge-API, no way to
+grade its own homework).
+
+| Backend | Seed | Held-out before → after | Nights |
+|---|---|---|---|
+| **Claude (Haiku 4.5)** | brief-writer | **0.00 → 1.00** | 1 |
+| **Codex** | brief-writer | **0.00 → 1.00** | 2 |
+
+Both took a brief-writer with no risks section / no confidence level and, within
+1–2 nights, proposed gated edits that lifted the held-out score to perfect —
+into the protected `LEARNED` block, nothing else touched. The Codex 2-night
+trace even shows the optimizer **diagnosing its own residual failure** and
+adding a meta-rule to fix it. Full writeup + reproduction:
+[`docs/sleep/real_api_results.md`](../docs/sleep/real_api_results.md).
+
+Reproduce:
+
+```bash
+git clone https://github.com/garrytan/gbrain-evals /tmp/gbrain-evals
+python -m skillopt_sleep.experiments.run_gbrain --backend claude --model haiku \
+  --seeds brief-writer --data-root /tmp/gbrain-evals/eval/data/skillopt-v1 \
+  --nights 1 --limit-replay 3 --limit-holdout 3
+python -m skillopt_sleep.experiments.run_gbrain --backend codex \
+  --seeds brief-writer --data-root /tmp/gbrain-evals/eval/data/skillopt-v1 \
+  --nights 1 --limit-replay 3 --limit-holdout 3
+```
+
+## Deterministic proof (no API, no keys)
+
+```bash
+python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves
+python -m skillopt_sleep.experiments.run_experiment --persona programmer  --assert-improves
+```
+
+Each prints the held-out score rising from baseline toward 1.0 as the gate
+accepts the general rules your tasks need, and confirms the gate **rejects** an
+injected harmful edit. Recorded output: [`docs/sleep/experiment_results.md`](../docs/sleep/experiment_results.md).
+
+## Schedule it nightly
+
+```bash
+"${CLAUDE_PLUGIN_ROOT}/scripts/install-cron.sh" "$(pwd)"   # prints a crontab line; installs nothing
+```
+
+## Safety
+
+- **Read-only** harvest of `~/.claude`. `mock` replay has no side effects.
+- Proposals are **staged**, never auto-applied (unless you opt in with `--auto-adopt`).
+- Every adopt writes a backup under the staging dir's `backup/`.
+- Per-night **token/task budget caps**; secrets redacted from prompts.
+- `fresh` replay (Phase 3) runs only in throwaway git worktrees.
+
+## Status
+
+Phase 1 (engine + deterministic experiment + plugin surface) is complete.
+Phase 3 adds the real-API miner/judge and `fresh` worktree replay. See
+[`docs/superpowers/specs/2026-06-07-skillopt-sleep-claude-code-plugin-design.md`](../docs/superpowers/specs/2026-06-07-skillopt-sleep-claude-code-plugin-design.md).

+
+(If `$ARGUMENTS` is empty, treat it as `status`.)
+
+## How to run it
+
+The engine is the `skillopt_sleep` Python package in this repo. Use the
+**plugin's bundled runner** so the right interpreter and repo are on the path:
+
+```bash
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" <action> --project "$(pwd)" --scope invoked
+```
+
+`<action>` is one of:
+
+| action    | what it does |
+|-----------|--------------|
+| `status`  | show how many nights have run + the latest staged proposal (READ-ONLY) |
+| `dry-run` | harvest → mine → replay → report, but **stage nothing** (safe preview) |
+| `run`     | full cycle: also **stage** a reviewed proposal (still does NOT touch live files) |
+| `adopt`   | apply the latest staged proposal to live `CLAUDE.md` / `SKILL.md` (backs up first) |
+| `harvest` | debug: print the recurring tasks mined from recent sessions |
+
+Default backend is `mock` (deterministic, no API spend). To use real Anthropic
+budget for genuine improvement, add `--backend anthropic`.
+
+## Steps to follow
+
+1. **Run the requested action** via the bundled runner above. Capture stdout.
+2. **For `run` / `dry-run`:** after it completes, `Read` the generated
+   `report.md` in the staging dir it prints, and show the user:
+   - held-out score: baseline → candidate (the proof it helped)
+   - the gate decision (accept/reject) and the exact edits it proposes
+   - where the proposal is staged
+3. **For `run` that produced an accepted proposal:** tell the user the diff is
+   staged and that **nothing live changed yet**. Offer to run `/sleep adopt`.
+4. **For `adopt`:** confirm which live files were updated and that backups were
+   written under the staging dir's `backup/`.
+5. **Never** edit `CLAUDE.md` or `SKILL.md` yourself — only the `adopt` action
+   does that, with a backup. Respect the review gate.
+
+## Safety reminders
+
+- Harvest is **read-only** over `~/.claude`. Replay in `mock` mode runs no
+  shell side effects.
+- The cycle stages proposals; the user is in control of adoption.
+- If the user asks to schedule this nightly, point them at
+  `${CLAUDE_PLUGIN_ROOT}/scripts/install-cron.sh` (prints a crontab line; does
+  not install anything without confirmation).

+description: "Use when the user wants their Claude agent to self-improve from past usage, asks about a nightly/offline 'sleep' or 'dream' cycle, memory/skill consolidation, or says things like 'make my agent better the more I use it', 'review my past sessions', 'learn my preferences', 'consolidate what you learned', 'run the sleep cycle', or wants to schedule offline self-optimization. Drives the skillopt_sleep engine: harvest past sessions -> mine recurring tasks -> replay offline -> consolidate validated CLAUDE.md/SKILL.md behind a held-out gate."

+
+# SkillOpt-Sleep: offline self-evolution for a local Claude agent
+
+SkillOpt-Sleep gives the user's agent a **sleep cycle**. While the user is
+offline (e.g. nightly), it reviews their real past Claude Code sessions,
+re-runs recurring tasks on their own API budget, and consolidates what it
+learns into **memory** (`CLAUDE.md`) and **skills** (`SKILL.md`) — but only
+keeps changes that pass a held-out validation gate, and only after the user
+adopts them. The agent gets measurably better at *this* user's recurring work,
+with no model-weight training. It is the deployment-time analogue of training:
+short-term experience → long-term competence.
+
+It synthesizes three ideas:
+- **SkillOpt** — the skill/memory doc is trainable text; bounded add/delete/replace
+  edits; accepted only through a held-out gate; rejected edits become negative feedback.
+- **Claude Dreams** — offline consolidation that reads past sessions and rebuilds
+  memory (dedup/merge/resolve); the input is never mutated; output is reviewed then adopted.
+- **Agent sleep** — periodic offline replay turns episodes into durable skill.
+
+## When to use this skill
+
+Trigger when the user wants any of:
+- "make my agent learn from how I use it" / "get better the more I use it" / "remember my preferences across sessions"
+- a nightly/scheduled or on-demand **offline self-improvement / dream / sleep** run
+- to **review past sessions/trajectories** and distill recurring tasks
+- to **consolidate** feedback into `CLAUDE.md` or a managed skill
+- to **schedule** the cycle (cron) or **adopt** a staged proposal
+
+## The cycle (six stages)
+
+1. **Harvest** — read `~/.claude/projects/*/<session>.jsonl` + `~/.claude/history.jsonl` (READ-ONLY) → session digests.
+2. **Mine** — digests → `TaskRecord`s (recurring intents + outcome labels + checkable refs where possible).
+3. **Replay** — re-run tasks offline under the *current* skill+memory → (hard, soft) scores.
+4. **Consolidate** — reflect on failures → propose bounded edits → **gate** on a held-out slice; accept only if it strictly improves.
+5. **Stage** — write `proposed_CLAUDE.md`, `proposed_SKILL.md`, a diff, and `report.md` into `<project>/.skillopt-sleep/staging/<date>/`. **Nothing live changes.**
+6. **Adopt** — explicit (or opt-in auto): copy staged files over live ones, backing up first.
+
+## How to drive it
+
+Prefer the `/sleep` command. Under the hood it calls the bundled runner:
+
+```bash
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" status                       # what's happened
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" dry-run --project "$(pwd)"    # safe preview
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" run --project "$(pwd)"        # full cycle, stages a proposal
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" adopt --project "$(pwd)"      # apply staged proposal (with backup)
+```
+
+- Default backend is `mock` (deterministic, **no API spend**) — good for trying the plumbing.
+- Add `--backend claude` or `--backend codex` to spend the user's real budget for genuine improvement.
+- Scope defaults to the invoked project; `--scope all` harvests every project.
+
+## Hard rules
+
+- **Never** hand-edit the user's `CLAUDE.md` / `SKILL.md` as part of this skill.
+  Only the `adopt` action changes live files, and it backs them up first.
+- Harvest is read-only. `mock` replay has no side effects.
+- Always show the user the **held-out baseline → candidate** score and the
+  exact proposed edits before suggesting adoption. Evidence before adoption.
+- If asked whether it really helps, run
+  `python -m skillopt_sleep.experiments.run_experiment --persona researcher --json`
+  — a deterministic demo that proves held-out lift and that the gate blocks
+  harmful edits.
+
+## Validate / demo
+
+```bash
+# deterministic proof (no API): held-out score rises, gate blocks regressions
+python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves
+python -m skillopt_sleep.experiments.run_experiment --persona programmer  --assert-improves
+```

+`docs/superpowers/specs/2026-06-07-skillopt-sleep-claude-code-plugin-design.md`
