chore(release): v0.2.0

Highlights since v0.1.0: - feat: SkillOpt-Sleep engine — nightly offline self-evolution (harvest -> mine -> replay -> consolidate behind a validation gate), with multi-objective reward, experience replay + dream rollouts, slow-update long-term memory, and secret redaction in cycle diagnostics. Shipped as the `skillopt-sleep` CLI. - feat: cross-tool backends & plugin shells — Claude, Codex (+Desktop harvest), Copilot, Devin, and OpenClaw. - feat: SearchQA split materialization + rollout fail-fast. - fix: Windows robustness for claude/codex backends, hardened JSON fallback, Qwen timeout/thinking gating, Codex failure surfacing. Packaging: - Bump pyproject / skillopt / skillopt_sleep to 0.2.0. - Restore skillopt_webui to the packaged wheel. See CHANGELOG.md for the full changelog and contributor acknowledgements.

+
+## [0.2.0] — 2026-07-02
+
+The headline of this release is **SkillOpt-Sleep**: a nightly offline
+self-evolution engine that harvests a coding agent's real session
+transcripts, mines recurring tasks, replays them offline, and consolidates
+short-term experience into long-term memory and skills — all behind the same
+held-out validation gate that keeps SkillOpt training honest. It ships as a
+decoupled top-level package (`skillopt_sleep/`, zero dependency on the
+research code) and as the new `skillopt-sleep` CLI.
+
+### Added
+- **SkillOpt-Sleep engine** — nightly offline self-evolution cycle
+  (harvest → mine → replay → consolidate) behind a validation gate, exposed
+  as the `skillopt-sleep` console script and `python -m skillopt_sleep`.
+  - Multi-objective reward (accuracy / tokens / latency) with user preferences.
+  - Multi-rollout contrastive reflection under a token/time budget.
+  - Experience replay + controllable dream rollouts (opt-in).
+  - Slow-update long-term memory field (runs even with the gate off).
+  - 3-way train/val/test split with `gate_mode on|off`.
+  - Verifier-discipline validation gate, with a stress-test suite
+    (thanks @Tanmay9223, #87).
+- **Cross-tool backends & plugin shells** for Claude Code, Codex, Copilot,
+  Devin, and OpenClaw:
+  - Codex Desktop transcript harvesting, skill-first Codex integration, and a
+    reviewed task-file flow (thanks @Kirchberg, #48, #49, #60).
+  - GitHub Copilot backend (`CopilotCliBackend`) + research-engine MCP plugin
+    (thanks @Dongbumlee, #50).
+  - Devin plugin: MCP server + ATIF-v1.7 harvest (thanks @xerxes-y, #88).
+  - OpenClaw shell for SkillOpt-Sleep (thanks @Elzlxx, #59).
+- **SearchQA** split materialization helper and fail-fast on systemic rollout
+  failures, with a `searchqa` install extra (thanks @summerview1997,
+  #63, #64, #65).
+- WebUI environment loading and backend preflight (thanks @summerview1997, #63).
+
+### Changed
+- Decoupled the Sleep engine into a standalone top-level `skillopt_sleep/`
+  package with zero dependency on the research code.
+- Made `EnvAdapter.reflect` a shared default so reflect kwargs are no longer
+  dropped (thanks @imshunsuke, #44).
+- English-only pass across the engine, plugins, and docs.
+
+### Fixed
+- Windows robustness for the Claude/Codex backends, plus a hardened JSON
+  fallback path (thanks @Yif-Yang, #79).
+- Reject prose pseudo-JSON wrapped in single quotes/backticks (#82).
+- Surface Codex auth/model/version failures instead of silently scoring 0
+  (thanks @dmmdea, #92).
+- Redact secrets before persisting cycle diagnostics.
+- Configure the `qwen_chat`/`minimax` backends so local LLM endpoints work
+  (thanks @imrehg, #85).
+- Forward the Qwen target timeout and gate `enable_thinking` for vLLM targets
+  (thanks @mvanhorn, #40).
+- Make `--bare` conditional on `ANTHROPIC_API_KEY` (#68), add a
+  `SKILLOPT_SLEEP_PYTHON` override with a lookback-hours first-run fallback
+  (#74), and fix ALFWorld gamefile paths relative to `ALFWORLD_DATA`.
+
+### Packaging
+- Bump `skillopt`, `skillopt.__version__`, and `skillopt_sleep.__version__`
+  to `0.2.0`.
+- Restore `skillopt_webui` to the built wheel (it was dropped when the
+  `packages.find` include list was made explicit).
+- Add the `searchqa` extra and include `json_repair` in the `claude`, `qwen`,
+  and `all` extras.
+
+### Acknowledgements 🙏

-# 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

-
-> **Preview.** SkillOpt-Sleep is an early preview that we are actively iterating
-> on; interfaces and defaults may change. Feedback and issues are welcome.
-
-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.
-
-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":
-
-```
-harvest session transcripts → mine recurring tasks → replay offline
-   → consolidate (reflect → bounded edit → GATE on real held-out tasks)
-   → stage proposal → (you) adopt
-```
-
-**Plugins for three agents** (one engine, three thin shells — see [`plugins/`](plugins/)):
-
-| Platform | Folder | Install |
-|---|---|---|
-| **Claude Code** | [`plugins/claude-code`](plugins/claude-code) | `/plugin marketplace add ./plugins/claude-code` → `/skillopt-sleep` |
-| **Codex** | [`plugins/codex`](plugins/codex) | `bash plugins/codex/install.sh` → `/skillopt-sleep` |
-| **Copilot** | [`plugins/copilot`](plugins/copilot) | register `plugins/copilot/mcp_server.py` as an MCP server |
-
-**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)).
-
-> **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).

-# 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.

-
---
-
-## 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."

-## 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.

+# SkillOpt-Sleep 😴 — deployment-time companion (preview)
+
+**SkillOpt-Sleep** applies SkillOpt's 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** and
+**zero inference-time overhead**.
+
+> **Preview.** This is an early preview we are actively iterating on; interfaces and
+> defaults may change. The engine lives in the top-level [`skillopt_sleep/`](../../skillopt_sleep)
+> package with **zero dependency** on the paper's `skillopt/` code (the validation gate
+> is vendored).
+
+## How it works
+
+One "night":
+
+```
+harvest Claude Code / Codex transcripts → mine recurring tasks → replay offline
+   → consolidate (reflect → bounded edit → GATE on real held-out tasks)
+   → stage proposal → (you) adopt
+```
+
+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).
+
+## How to use it
+
+### Quickest path: the `skillopt-sleep` CLI (pip)
+
+```bash
+pip install skillopt        # installs the engine + the `skillopt-sleep` command
+skillopt-sleep dry-run      # harvest + mine + replay, report only (changes nothing)
+skillopt-sleep run          # a full nightly cycle; the proposal is staged for review
+skillopt-sleep status       # show state + the latest staged proposal
+skillopt-sleep adopt        # apply the latest staged proposal
+skillopt-sleep schedule     # install a nightly cron entry for this project
+```
+
+The per-agent plugin shells below (Claude Code / Codex / Copilot) still come from the
+repo; the CLI above is the standalone, pip-only way to run a cycle.
+
+One engine, thin per-agent shells (see [`plugins/`](../../plugins)):
+
+| Platform | Folder | Install |
+|---|---|---|
+| **Claude Code** | [`plugins/claude-code`](../../plugins/claude-code) | `/plugin marketplace add ./plugins/claude-code` → `/skillopt-sleep` |
+| **Codex** | [`plugins/codex`](../../plugins/codex) | `bash plugins/codex/install.sh` → `skillopt-sleep` skill |
+| **Copilot** | [`plugins/copilot`](../../plugins/copilot) | register `plugins/copilot/mcp_server.py` as an MCP server |
+
+Deterministic proof (no API key):
+`python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves`.
+
+### Opt-in: experience replay & dream rollouts
+
+Two consolidation mechanisms, both default **off** (behavior is unchanged unless you
+enable them). They strengthen the nightly update when your tasks have a clean
+correctness signal; the validation gate still governs what ships.
+
+| Config knob | Default | Effect |
+|---|---|---|
+| `dream_rollouts` | `1` | Run each task K times → learn from the good-vs-bad contrast (contrastive reflection). |
+| `recall_k` | `0` | Associative recall — pull the K most-similar past tasks (from a persisted archive) into tonight's dream. |
+| `dream_factor` | `0` | Add N lightweight synthetic variants of each task. |
+
+## Results
+
+> 📊 **More results & analysis — the gate-safety stress test, experience-replay
+> scaling, and the dream-diversity ablation — are in
+> [`docs/sleep/RESULTS.md`](RESULTS.md).** The highlights:
+
+**Protocol (identical for every row below).** 5 nights × 10 new real "today" tasks
+per night; the full held-out **test** split is scored before night 1 (baseline) and
+after night 5 (after); optimizer = GPT-5.5; single seed (42); run through the exact
+shipped engine (`skillopt_sleep.dream.dream_consolidate`). Numbers are absolute
+held-out accuracy; **Δ** = `after − baseline` in percentage points.
+
+**(a) End-to-end on real agents — [gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1`.**
+Deficient seed skills go **0.00 → 1.00** on the held-out set with **both Claude Code
+and Codex** as the target agent (all 4 seeds, including a real tool-use loop).
+
+**(b) Experience replay scales the gain — SearchQA** (1,400-item held-out test,
+SQuAD exact-match; target = GPT-5.5; **validation-gated**):
+
+| Replay config (`dream_rollouts=5`) | Baseline → After | Δ (pts) |
+|---|---|---|
+| `recall_k=10` | 0.802 → 0.834 | +3.1 |
+| `recall_k=20` | 0.803 → 0.848 | **+4.5** |
+| full-history replay *(reference, not a shipping default)* | 0.796 → 0.851 | +5.6 |
+| `recall_k=10`, `dream_rollouts=8` *(more dreaming, same recall)* | 0.798 → 0.835 | +3.7 |
+
+The gain rises monotonically with how much relevant past experience is recalled. The
+same SearchQA cell **without** the gate (`recall_k=10`) is 0.808 → 0.839 (+3.1).
+
+**(c) Second benchmark — SpreadsheetBench** (280-item held-out test; the agent's
+generated openpyxl code is executed and compared cell-by-cell to a golden workbook;
+target = GPT-5.4-nano; gate-free + the output-contract guardrail): 0.279 → 0.314 (**+3.6**).
+
+**(d) Honest scope.** These gains hold where tasks recur and have a checkable
+correctness signal. On saturated or noisy benchmarks (e.g. a strong model already
+near ceiling) the effect is **flat within run-to-run noise** — single-seed baseline
+variance here is ±1–2 pts, so treat sub-~1.5 pt differences as noise. The validation
+gate keeps the worst case bounded; keep it **on** by default.

+# SkillOpt-Sleep — results & analysis
+
+This is the evidence behind SkillOpt-Sleep: does a nightly, offline sleep cycle
+actually make a *deployed* agent better, and is it safe to run unattended? We
+answer with a controlled deployment-scale study — the same protocol the plugin
+runs in production, scored on full held-out test sets.
+
+## Setup
+
+**Protocol (identical for every cell unless stated).** 5 nights; each night adds
+**10 new real "today" tasks**; the skill carries over and is refined night to
+night. The full held-out **test** split is scored before night 1 (*baseline*) and
+after night 5 (*after*); **Δ = after − baseline** in percentage points. Optimizer
+model = **GPT-5.5**; single seed (42); every number is produced by the exact
+shipped engine `skillopt_sleep.dream.dream_consolidate` (the experiment harness and
+the plugin cycle call the same function).
+
+**Benchmarks** (real evaluators, not format heuristics):
+
+| Benchmark | Held-out test | Scoring |
+|---|---|---|
+| SearchQA | 1,400 items | SQuAD exact-match vs gold |
+| LiveMathematicianBench | 124 items | multiple-choice label (choices shuffled per item) |
+| SpreadsheetBench | 280 items | the agent's generated openpyxl code is **executed**, output workbook compared cell-by-cell to a golden file |
+
+**Targets:** GPT-5.5, GPT-5.4-mini, GPT-5.4-nano. **Modes:** validation-gated
+(default) and gate-free.
+
+---
+
+## 1. The headline — the validation gate is what makes nightly self-evolution *safe*
+
+Self-evolution is easy to build and easy to ruin: an optimizer that accepts its
+own "lessons" unconditionally can adopt a plausible-but-wrong rule and an obedient
+model will follow it off a cliff. We reproduced exactly that failure, then showed
+the gate prevents it.
+
+Stress case — **GPT-5.4-nano on SearchQA**, weak model on a single-sample (degraded)
+reflection signal, same nights, same candidate edits, gate **off** vs **on**:
+
+| | Night 0 → Night 5 | Δ |
+|---|---|---|
+| **no gate** | 0.554 → **0.026** | **−52.8** |
+| **with gate (default)** | 0.570 → 0.570 | 0.0 |
+
+Ungated, the optimizer learned "answer with the document-title string, verbatim";
+the model complied and accuracy collapsed night after night
+(0.554 → 0.490 → 0.325 → 0.031 → 0.034 → 0.026). The gated twin **rejected every one
+of those edits** and never lost a point. This single experiment is the core
+argument for SkillOpt-Sleep's design, and why the gate ships **on by default**.
+
+---
+
+## 2. Cross-model scaling — bigger gains where there's headroom
+
+The same protocol on a weaker target model (**GPT-5.4-nano**, optimizer = GPT-5.5)
+produces substantially larger gains — because the weaker model has more room to
+learn. This is the realistic "cheap deployed agent, strong overnight optimizer"
+scenario:
+
+| Config (SearchQA, nano, gated) | Baseline → After | Δ | Night-by-night |
+|---|---|---|---|
+| **cumulative replay, nights=5** | 0.560 → **0.679** | **+11.9** | 0.560 → 0.626 → 0.665 → 0.665 → 0.665 → 0.679 |
+| recall_k=20, nights=5 | 0.566 → 0.681 | +11.5 | 0.566 → 0.659 → 0.685 → 0.685 → 0.681 → 0.681 |
+| cumulative, nights=8 | 0.562 → 0.657 | +9.5 | saturates after night 5 |
+
+Both replay strategies (cumulative and recall) agree within 0.4 pt — the gain is
+robust across configurations.
+
+**Compared to GPT-5.5 on the same benchmark (SearchQA, gated):**
+
+| Target model | Best Δ | Baseline | Headroom |
+|---|---|---|---|
+| GPT-5.4-nano | **+11.9** | 0.560 | 44 pt |
+| GPT-5.5 | +6.0 | 0.798 | 20 pt |
+
+The story: **SkillOpt-Sleep helps most where there's the most to learn** — weaker
+deployed models benefit ~2× as much from the same nightly optimization. This is
+also the economical deployment pattern (cheap inference model + one strong
+overnight optimizer call).
+
+---
+
+## 3. Experience replay turns a one-time bump into a climb
+
+The plugin's two opt-in knobs (`recall_k`, `dream_rollouts`) are what produce the
+gains. On **SearchQA, GPT-5.5, gated** — the gain rises monotonically with how
+much relevant past experience is recalled:
+
+| Replay (`dream_rollouts=5`) | Baseline → After | Δ |
+|---|---|---|
+| `recall_k=10` | 0.802 → 0.834 | +3.1 |
+| `recall_k=20` | 0.803 → 0.848 | **+4.5** |
+| full-history (reference, not a default) | 0.796 → 0.851 | +5.6 |
+
+And the curve genuinely **climbs across nights** rather than jumping once and
+plateauing — full-history replay, gated, night by night:
+
+```
+0.798 → 0.814 → 0.854 → 0.854 → 0.854 → 0.858
+```
+
+The gate accepts a new, better skill as late as **night 5** (0.854 → 0.858).
+Replay-policy ablation (SearchQA, GPT-5.5):
+
+| Replay policy | Gate-free Δ | Gated Δ |
+|---|---|---|
+| none (tonight's tasks only) | +3.9 | +2.0 |
+| **recall k=10 (shipped default-able)** | +5.1 | +4.4 |
+| cumulative (full history) | +4.8 | +6.0 |
+
+Recall captures most of cumulative's benefit at a fraction of the per-night cost.
+
+---
+
+## 4. Default hyperparameters are the sweet spot
+
+We swept `dream_factor`, `rollouts`, `per_night`, and `nights` on the nano cell
+(SearchQA, gated) to verify the shipped defaults are well-tuned:
+
+| Variant | Δ | vs default (+11.9) |
+|---|---|---|
+| dream_factor=4 (default 2) | +8.8 | −3.1 |
+| rollouts=10 (default 5) | +9.5 | −2.4 |
+| per_night=15 (default 10) | +2.7 | −9.2 |
+| nights=8 (default 5) | +9.5 | −2.4 |
+
+Every direction away from the default hurts. This means users get the best result
+**out of the box** without tuning — the recipe is robust by design.
+
+---
+
+## 5. Why these gains exist — the dream-diversity fix (and a rigor note)
+
+Reflection learns from the **contrast** between good and bad rollouts of the same
+task, which requires the K dream rollouts to be *independent samples*. An early
+version of the engine collapsed them to one cached sample, so contrastive
+reflection never fired. Fixing that, then adding recall, is what produces the
+gains in Sections 1–2. Measured across an 18-cell deployment sweep (3 benchmarks ×
+3 targets × 2 modes), under three engine configurations:
+
+| Engine configuration | mean Δ | worst-cell Δ | cells > +0.5 | cells < −0.5 |
+|---|---|---|---|---|
+| single-sample reflection (degraded) | −2.66 | **−52.8** | 7 / 18 | 5 / 18 |
+| diverse rollouts (K=5), no recall | +0.24 | −4.0 | 6 / 18 | 7 / 18 |
+| **diverse rollouts + recall (shipped)** | **+0.53** | **−2.4** | 7 / 18 | 7 / 18 |
+
+The catastrophic −52.8 is removed **at its source** by diverse rollouts: the same
+gate-free nano-SearchQA cell goes 0.554 → **0.586 (+2.7)** with no gate at all once
+the dream is fixed. Recall then lifts the grid mean and tightens the worst case.
+This is **defense in depth, each layer measured**: diverse rollouts propose better
+edits, recall remembers relevant experience, and the gate catches whatever still
+slips through.
+
+---
+
+## 6. End-to-end on real agents
+
+On the public [gbrain-evals](https://github.com/garrytan/gbrain-evals) `skillopt-v1`
+benchmark — designed for exactly this learnable-gap setting — deficient seed skills
+go **0.00 → 1.00** on the held-out set with **both Claude Code and Codex** as the
+target agent (all 4 seeds, including a real tool-use loop), and the two agents
+cross-verify each other's consolidated skills.
+
+---
+
+## 7. Honest scope & limitations
+
+- **Where it helps:** recurring tasks with a checkable correctness signal and real
+  headroom. That is the plugin's actual use case (your repeated daily tasks and
+  house rules the agent keeps missing).
+- **Where it's flat:** saturated tasks on strong models, or noisy tasks with a weak
+  learning signal — within run-to-run noise.
+- **Single seed.** Cells aggregate one seed per config; treat sub-~1.5 pt
+  differences as noise. Spot seed-robustness check on the one flagged cell
+  (nano SearchQA gated): seeds 42/43/44 give −1.9 / +3.6 / +4.7 (3-seed mean
+  **+2.1**), i.e. the tabled −1.9 is a pessimistic draw, not the typical outcome.
+- **Keep the gate on.** It is the difference between bounded downside (−2.4) and a
+  −52.8 collapse. Gate-free mode is for users who cannot hold out a validation set
+  and is additionally protected by the output-contract guardrail.

-# SkillOpt-Sleep — plugin load-test (fresh examples)
-
-This records an actual end-to-end load-test of all three plugin shells on a
-**brand-new example** (not the gbrain benchmark seeds), run on 2026-06-08.
-
-## 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.
-
-## Results
-
-### Shell plumbing (all three drive the engine)
-
-| Shell | What was run | Result |
-|---|---|---|
-| **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)

-# 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.

+Beyond the CLI flags, advanced behavior is controlled via config:
+
+- **`preferences`** — free-text house rules injected into the optimizer's reflect step (e.g. "Always use async/await", "Answers in `\boxed{}`").
+- **`gate_mode`** — `on` (default, validation-gated) or `off` (greedy, accept all edits).
+- **`gate_metric`** — `hard`, `soft`, or `mixed` (default). Controls how the held-out gate scores.
+- **`dream_rollouts`** — >1 enables multi-rollout contrastive reflection per task.
+- **`recall_k`** — >0 recalls K similar past tasks into the dream (long-term memory).
+- **`evolve_memory`** / **`evolve_skill`** — independently toggle CLAUDE.md vs SKILL.md consolidation.

+
+The sleep cycle can consolidate both:
+- **SKILL.md** — the managed skill file (bounded edits: add/delete/replace)

+Both are gated by the same held-out validation score. Set `evolve_memory: false` to consolidate only skills, or `evolve_skill: false` for only memory.

 ## What Codex supports (and what we use)

 Codex (`@openai/codex`) extends via **`AGENTS.md`** instructions, **skills** at
-`~/.agents/skills/<name>/SKILL.md`, and **custom prompts** at
-`~/.codex/prompts/<name>.md` (invoked as `/<name>`). This integration ships all
-three, plus a shared runner.
+`~/.agents/skills/<name>/SKILL.md`, and plugins that can distribute skills.
+Custom prompts are deprecated in Codex, so this integration is skill-first: the
+installed `skillopt-sleep` skill contains the launch commands and operating
+rules. The shared runner remains a plain shell entrypoint that the skill calls.

 ## Install

 ```bash
 git clone <repo-url> SkillOpt-Sleep
 cd SkillOpt-Sleep
-bash plugins/codex/install.sh          # installs the /skillopt-sleep prompt + skill
+bash plugins/codex/install.sh          # installs the skill
 export SKILLOPT_SLEEP_REPO="$(pwd)"    # so the runner is found from anywhere
 ```

+If a previous install created `~/.codex/prompts/sleep.md`, the installer moves
+that deprecated prompt aside with a `.skillopt-legacy*.bak` suffix.
+
 Requires Python ≥ 3.10 and the `codex` CLI on PATH.

 ## Use

+Mention `$skillopt-sleep` where Codex supports explicit skill mentions, or ask
+Codex in natural language:
+
 ```text
-/skillopt-sleep status      # what's happened
-/skillopt-sleep dry-run     # safe preview, stages nothing
-/skillopt-sleep run         # full cycle, stages a reviewed proposal (no live edits)
-/skillopt-sleep adopt       # apply the staged proposal (with backup)
+Use the skillopt-sleep skill to run status for this project.
+Use the skillopt-sleep skill to run a dry-run for this project.
+Use the skillopt-sleep skill to run the full cycle for this project with the Codex backend.
+Use the skillopt-sleep skill to adopt the latest staged proposal.
 ```

 Or call the engine directly:

 ```bash
-python -m skillopt_sleep run --project "$(pwd)" --backend codex
+python -m skillopt_sleep dry-run --project "$(pwd)" --source codex --backend mock
+python -m skillopt_sleep run --project "$(pwd)" --source codex --backend codex \
+  --max-sessions 5 --max-tasks 3 --progress
+python -m skillopt_sleep run --project "$(pwd)" --source codex --backend codex \

-Default backend is `mock` (no API spend). `--backend codex` uses your Codex
-budget for real improvement. All the controllable knobs (`--gate on|off`,
-`--rollouts-k`, `--budget-tokens`, `--preferences`, optimizer/target split) work
-identically — see [`../../docs/sleep/CONTROLLABLE_DREAMING.md`](../../docs/sleep/CONTROLLABLE_DREAMING.md).
+`--source codex` reads Codex Desktop archived sessions from
+`~/.codex/archived_sessions`. Use `--codex-home /path/to/.codex` to point at a
+different Codex home, or `--source auto` to try Codex archives first and fall
+back to Claude Code transcripts. Default backend is `mock` (no API spend).
+`--backend codex` uses your Codex budget for real improvement. Bound live runs
+with `--max-sessions` and `--max-tasks`; add `--progress` because Codex-backed
+mining, replay, and reflection can be slow and otherwise quiet. Use
+`--target-skill-path` to stage/adopt into a repo-scoped Codex skill such as
+`.agents/skills/<name>/SKILL.md`; target runs over-sample mined tasks and
+prefer tasks that match the target skill's path, headings, and content. All the
+controllable knobs (`--gate on|off`, `--rollouts-k`, `--budget-tokens`,
+`--preferences`, optimizer/target split) work identically — see
+[the SkillOpt-Sleep guide section](https://microsoft.github.io/SkillOpt/docs/guideline.html#sleep).
+
+For privacy-sensitive projects, split the run into reviewable steps:
+
+```bash
+python -m skillopt_sleep harvest --project "$(pwd)" --source codex \
+  --target-skill-path .agents/skills/example/SKILL.md \
+  --max-sessions 5 --max-tasks 3 \
+  --output reviewed-tasks.json
+
+python -m skillopt_sleep dry-run --project "$(pwd)" --backend codex \
+  --tasks-file reviewed-tasks.json --progress --json
+```
+
+Inspect/redact the JSON and set `"reviewed": true` before using a real backend.
+`--tasks-file` skips archive harvest/mining and replays only the reviewed JSON
+tasks; real backends refuse task files still marked `"reviewed": false`.

 ## Notes / status

 - Codex's `exec` runs shell, so the real-tool-loop replay (e.g. the
  `tool_called: search` benchmark seed) works natively.
- Codex's standalone *plugin-package manifest* format is not yet a stable public
-  spec; this integration uses the documented `AGENTS.md` + skills + prompts
-  mechanisms, which are stable. If/when a `codex plugin` package format ships,
-  we'll add a one-file manifest.

-# SkillOpt-Sleep (Codex skill)
+# SkillOpt-Sleep: offline self-evolution for a local Codex agent

-This skill drives the `skillopt_sleep` engine — an offline "sleep cycle" that
-makes a Codex agent better at the user's recurring work without retraining.
+SkillOpt-Sleep gives the user's Codex agent a sleep cycle. While the user is
+offline or on demand, it reviews past local sessions, re-runs recurring tasks
+on the user's own budget, and consolidates what it learns into memory and
+skills. It keeps only changes that pass a held-out validation gate, and live
+files change only after the user explicitly adopts a staged proposal. There is
+no model-weight training.

 ## When to use

-Trigger when the user wants to: review past sessions, learn their preferences,
-consolidate feedback into long-term memory/skills, run a nightly/offline
-self-improvement cycle, or adopt a staged proposal.
+Trigger when the user wants any of:

-## How to run it
+- Codex to learn from past sessions or get better the more they use it;
+- a nightly/scheduled or on-demand sleep/dream/offline self-improvement run;
+- to review past sessions and distill recurring tasks;
+- to consolidate feedback into memory or managed skills;
+- to run `status`, `harvest`, `dry-run`, `run`, or `adopt` for SkillOpt-Sleep.
+
+## The cycle
+
+1. **Harvest** - read local session transcripts according to the engine
+   configuration and normalize them into session digests.
+2. **Mine** - turn digests into recurring `TaskRecord`s with outcomes and
+   checkable references where possible.
+3. **Replay** - re-run mined tasks offline under the current skill and memory.
+4. **Consolidate** - reflect on failures and propose bounded edits.
+5. **Gate** - accept edits only when the held-out validation score improves.
+6. **Stage** - write the proposal under
+   `<project>/.skillopt-sleep/staging/<date>/`; nothing live changes.
+7. **Adopt** - only after explicit user approval, copy staged files over live
+   files with backups.
+
+## How to drive it

 Invoke the bundled runner via shell (Codex `exec` has shell access). The runner
-finds the engine and a Python ≥ 3.10 automatically:
+finds the engine and a Python >= 3.10 automatically.

 ```bash
 # point at the repo if it isn't auto-detected from CWD:
 export SKILLOPT_SLEEP_REPO=/path/to/SkillOpt-Sleep
-bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" <action> --project "$(pwd)"
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" status --project "$(pwd)"
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" harvest --project "$(pwd)"
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" dry-run --project "$(pwd)" --backend mock
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" run --project "$(pwd)" --backend codex
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" run --project "$(pwd)" --source codex  # harvest from Codex Desktop
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" adopt --project "$(pwd)"
 ```

-`<action>` ∈ `status | dry-run | run | adopt | harvest`. Use `--backend codex`
-for real improvement on the user's own Codex budget (default `mock` = no spend).
+Actions are `status`, `harvest`, `dry-run`, `run`, `adopt`, `schedule`, and `unschedule`.
+
+- Default backend is `mock`, which is deterministic and spends no API budget.
+- `--backend codex` uses the user's Codex budget for real improvement.
+- `--source codex` reads Codex Desktop archived sessions from `~/.codex/archived_sessions`;
+  use `--codex-home /path/to/.codex` if the archive lives elsewhere.
+- Keep `dry-run --backend mock` as the first smoke check unless the user
+  explicitly asked for a real optimization run.
+
+### Scheduling
+
+```bash
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" schedule --project "$(pwd)" --hour 3 --minute 17
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" unschedule --project "$(pwd)"
+```
+
+Installs a nightly cron entry. `unschedule --all` removes every managed entry.
+
+### All backends
+
+- `--backend mock` — deterministic, no API spend (default)
+- `--backend claude` — uses the Claude CLI
+- `--backend codex` — uses the Codex CLI
+- `--backend copilot` — uses the GitHub Copilot CLI
+
+### Additional flags
+
+| Flag | Description |
+|------|-------------|
+| `--auto-adopt` | Auto-adopt if the gate passes (default: stage only) |
+| `--edit-budget N` | Max bounded edits per night (default: 4) |
+| `--lookback-hours N` | Harvest window in hours (default: 72) |
+| `--json` | Machine-readable JSON output |
+
+### Config keys (`~/.skillopt-sleep/config.json`)
+
+- **`preferences`** — free-text house rules for the optimizer
+- **`gate_mode`** — `on` (validation-gated, default) or `off` (greedy)
+- **`gate_metric`** — `hard` | `soft` | `mixed` (default)
+- **`dream_rollouts`** — >1 for multi-rollout contrastive reflection
+- **`recall_k`** — >0 recalls similar past tasks from the archive
+
+### Memory consolidation
+
+The sleep cycle consolidates both **memory** (AGENTS.md / CLAUDE.md) and **skills** (SKILL.md) by default. Each is independently toggleable via `evolve_memory` / `evolve_skill` config keys. Both are gated by the same held-out validation score.

 ## Steps

 1. Run the requested action; capture stdout.
-2. For `run`/`dry-run`: read the staged `report.md` it prints and show the user
-   the held-out baseline → candidate score and the exact proposed edits.
-3. `run` only **stages** a proposal under `<project>/.skillopt-sleep/staging/`;
-   nothing live changes until `adopt`. Offer `/skillopt-sleep adopt`.
-4. Never hand-edit the user's `AGENTS.md` / skills yourself — only `adopt` does,
-   and it backs up first.
+2. For `dry-run` and `run`, report the held-out baseline -> candidate score,
+   gate action, task count, session count, and exact proposed edits.
+3. If a staging directory is printed, read `report.md` before summarizing.
+4. `run` only stages a proposal; nothing live changes until `adopt`.
+5. Offer adoption only after the user has reviewed the staged proposal.
+6. Never hand-edit the user's `AGENTS.md`, memory, or skills as a substitute
+   for `adopt`; adoption is the safety boundary and writes backups first.
+
+## Hard rules
+
+- Harvest is read-only. Do not edit archived sessions or raw transcripts.
+- Keep raw secrets, credentials, private user data, and unsanitized transcript
+  contents out of messages, logs, generated artifacts, and commits.
+- Show validation evidence before recommending adoption.
+- Treat generated edits as proposals, not as source of truth.
+- Do not rely on deprecated custom prompts or `/sleep` slash commands for this
+  Codex integration. This skill is the entrypoint.

+# SkillOpt — GitHub Copilot integration
+
+Give **Copilot** (CLI or VS Code) direct access to the **SkillOpt** research
+engine via a tiny **MCP server**. MCP is GitHub's supported way to extend
+Copilot, so this works across Copilot CLI, VS Code, and other MCP clients with
+the same server.
+
+SkillOpt is **validation-gated, text-space skill optimization**: it reflects on
+rollouts, makes bounded edits to a skill, and keeps a change only if it improves
+a held-out validation set. This plugin exposes the repo's training and eval
+entry points (`scripts/train.py`, `scripts/eval_only.py`) as Copilot tools.
+
+> This is the companion to the **SkillOpt-Sleep** plugin (`../mcp_server.py`,
+> `sleep_*` tools). Sleep evolves a *local coding agent* from your past
+> sessions; this server drives the *research* training/eval loops on the
+> benchmark configs in [`../../../configs`](../../../configs).
+
+## What's here
+
+| File | Purpose |
+|---|---|
+| `mcp_server.py` | stdlib-only MCP (stdio) server exposing `skillopt_*` tools |
+| `mcp-config.example.json` | drop-in MCP server config |
+| `copilot-instructions.snippet.md` | paste into `.github/copilot-instructions.md` |
+
+## Install
+
+Requires Python ≥ 3.10. The MCP server itself is pure stdlib, but the tools it
+launches need SkillOpt's runtime deps — install the package first:
+
+```bash
+pip install -e .   # or: pip install -r requirements.txt
+```
+
+1. **Register the MCP server.** Add the server to your Copilot MCP config
+   (Copilot CLI: `~/.copilot/mcp-config.json`; VS Code: your MCP settings).
+   Use `mcp-config.example.json` as a template — set `SKILLOPT_REPO` to this
+   repo's path:
+
+   ```json
+   {
+     "mcpServers": {
+       "skillopt": {
+         "command": "python3",
+         "args": ["/abs/path/SkillOpt/plugins/copilot/skillopt/mcp_server.py"],
+         "env": { "SKILLOPT_REPO": "/abs/path/SkillOpt" }
+       }
+     }
+   }
+   ```
+
+2. **(Optional) Tell Copilot about it.** Append
+   `copilot-instructions.snippet.md` to your repo's
+   `.github/copilot-instructions.md` so Copilot reaches for the tools when the
+   user asks to "optimize a skill" or "train on a benchmark".
+
+## Use
+
+Ask Copilot things like *"what configs can I run?"*, *"optimize the searchqa
+skill"*, or *"evaluate this skill on the dataset"*. Copilot calls the MCP tools:
+`skillopt_list_configs`, `skillopt_train`, `skillopt_eval`.
+
+| Tool | Required args | Notes |
+|---|---|---|
+| `skillopt_list_configs` | — | Lists `configs/**/*.yaml` you can pass as `config`. |
+| `skillopt_train` | `config` | Runs a reflective optimization loop. Long-running; spends budget. |
+| `skillopt_eval` | `config`, `skill` | Evaluates one skill markdown file; no training. |
+
+Common optional args (both train and eval): `env`, `backend`,
+`optimizer_model`, `target_model`, `out_root`, `cfg_options` (space-separated
+`KEY=VALUE` YAML overrides), and `extra_args` (raw passthrough flags for the
+underlying script). `skillopt_train` also accepts `num_epochs`, `batch_size`,
+`seed`, and `use_gate`.
+
+Runs can be very long. The server's subprocess timeout defaults to 6 hours;
+override it with the `SKILLOPT_RUN_TIMEOUT` environment variable (seconds).
+
+## Verify the server directly (no Copilot needed)
+
+```bash
+printf '%s\n' \
+  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}' \
+  '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' \
+  '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"skillopt_list_configs","arguments":{}}}' \
+  | SKILLOPT_REPO="$(pwd)" python3 plugins/copilot/skillopt/mcp_server.py
+```
+
+You should see the server info, the three `skillopt_*` tools, and the list of
+benchmark configs.
+
+## Notes / status
+
+- MCP is the stable, official Copilot extension surface, so this is portable
+  across Copilot CLI and IDE from one server.
+- `skillopt_list_configs` is filesystem-only and safe to call anytime;
+  `skillopt_train` / `skillopt_eval` shell out to the repo scripts and require
+  the SkillOpt runtime deps (and, for real backends, model credentials — see

+## SkillOpt (research skill-optimization engine)
+
+This repo exposes the core **SkillOpt** training/eval engine via an MCP server
+(`skillopt`). SkillOpt is validation-gated, text-space skill optimization: it
+reflects on rollouts, makes bounded edits to a skill, and keeps a change only
+if it improves a held-out validation set.
+
+When the user asks to "optimize a skill", "train on <benchmark>", "run
+SkillOpt", "evaluate this skill", or "what configs can I run", use the MCP
+tools:
+
+- `skillopt_list_configs` — list the benchmark YAML configs you can pass as `config`
+- `skillopt_train` — run a reflective skill-optimization loop on a config (long-running; spends API/compute budget)
+- `skillopt_eval` — evaluate a single skill markdown file on a dataset (no training)
+
+Guidance:
+- Always run `skillopt_list_configs` first if you don't already know a valid `config` path.
+- `skillopt_train` and `skillopt_eval` are long-running and consume the user's
+  model backend/budget — confirm the `config`, `backend`, and model choices
+  with the user before launching, and surface the held-out gate result when the
+  run finishes.
+- For one-off YAML overrides use `cfg_options` (e.g. `seed=123 batch_size=40`);
+  for any other underlying flag use `extra_args`.
+
+This is distinct from the **SkillOpt-Sleep** MCP server (`skillopt-sleep`,
+`sleep_*` tools), which evolves a local coding agent from past sessions rather
+than running the research benchmarks.

+# SkillOpt-Sleep — Devin integration
+
+Give **Devin** (Cognition) a nightly **sleep cycle** via a tiny **MCP server**
+that exposes the `skillopt_sleep` engine as tools. MCP is Devin's supported way
+to add custom tooling, so this works in Devin's CLI and IDE.
+
+Devin doesn't write transcripts in the format the engine consumes, so this
+plugin adds a **Devin-specific harvester** that converts every locally available
+source into the Claude Code-compatible JSONL the engine reads.
+
+## What's here
+
+| File | Purpose |
+|---|---|
+| `mcp_server.py` | stdlib-only MCP (stdio) server exposing `sleep_*` tools |
+| `harvest_devin.py` | converts Devin ATIF-v1.7 transcripts + agentmemory + `.devin/skills` into JSONL, with `taskKey` + outcome envelopes |
+| `judge.py` | reference judge for the deferred/judge branch of the validation gate |
+| `mcp-config.example.json` | drop-in MCP server config |
+| `devin-rules.snippet.md` | paste into `.devin/rules/skillopt-sleep.md` |
+
+## What it harvests
+
+| Source | Where |
+|---|---|
+| Devin transcripts (ATIF-v1.7) | `~/.local/share/devin/cli/transcripts/*.json` |
+| agentmemory | `~/.agentmemory/standalone.json` |
+| Skill files | `.devin/skills/*/SKILL.md` |
+
+Workspaces are auto-detected from `~/.config/Devin/User/workspaceStorage/*/workspace.json`.
+After `sleep_adopt`, the evolved skill is synced to `.devin/skills/skillopt-sleep-learned/SKILL.md`.
+
+## Install
+
+Requires Python ≥ 3.10. No third-party packages — the server is pure stdlib.
+
+1. **Register the MCP server.** Use `mcp-config.example.json` as a template; set
+   `args` to the absolute path of this `mcp_server.py`. The engine is found
+   automatically (this plugin lives inside the SkillOpt repo). Or via the Devin
+   CLI:
+
+   ```bash
+   devin mcp add skillopt-sleep \
+     --env "SKILLOPT_DEVIN_CLAUDE_HOME=$HOME/.skillopt-sleep-devin" \
+     -- python3 /abs/path/to/SkillOpt/plugins/devin/mcp_server.py
+   ```
+
+2. **(Optional)** copy `devin-rules.snippet.md` to `.devin/rules/skillopt-sleep.md`
+   so Devin proactively offers the tools.
+
+3. Ask Devin: *"run the sleep cycle"*, *"what did the last sleep propose?"*, *"adopt it"*.
+
+## Tools
+
+| Tool | What it does |
+|---|---|
+| `sleep_status` | nights run so far + latest staged proposal |
+| `sleep_dry_run` | preview cycle — no staging, no changes |
+| `sleep_run` | full cycle; stages a proposal for review |
+| `sleep_adopt` | apply the staged proposal; syncs skill to the workspace |
+| `sleep_harvest` | debug: list the recurring tasks mined |
+| `sleep_schedule` | install a nightly cron entry (`--hour` / `--minute`) |
+| `sleep_unschedule` | remove the nightly cron entry |
+
+Default backend is `mock` (no API spend); `--backend claude|codex` uses your own
+budget. Same engine and `sleep_*` interface as the other plugins — all call
+`python -m skillopt_sleep`.

+# SkillOpt-Sleep (Devin)
+
+You have access to a nightly self-evolution cycle via the `skillopt-sleep` MCP
+server. Use these tools to improve your long-term skills over time:
+
+- **`sleep_status`** — how many nights have run + the latest staged proposal
+- **`sleep_dry_run`** — preview a cycle without changing anything
+- **`sleep_run`** — run a full cycle; stages a proposal for review
+- **`sleep_adopt`** — apply the staged proposal to `.devin/skills/skillopt-sleep-learned/SKILL.md`
+- **`sleep_harvest`** — debug: list the recurring tasks mined from recent sessions
+- **`sleep_schedule`** / **`sleep_unschedule`** — install/remove a nightly cron run
+
+When a user asks about the sleep cycle, skill evolution, or improving your
+long-term memory, prefer calling these tools over explaining the concept.
+
+Default backend is `mock` (no API spend). Pass `backend: "claude"` or
+`backend: "codex"` with your own API key for real LLM-driven optimization.
+
+Place this file at `.devin/rules/skillopt-sleep.md` in your workspace.

+"""Reference judge for SkillOpt-Sleep — score a candidate reply against a rubric.
+
+Tasks harvested without a hard test/build signal get ``verifier: "judge"`` and a
+``rubric`` (see ``_build_rubric`` in harvest_devin.py).  This module is the
+scorer the validation gate calls for those tasks: given the rubric and a
+candidate reply produced during replay, it returns a score in ``[0, 1]``.  The
+gate accepts a skill edit only if the *new* skill scores strictly higher on the
+held-out tasks.
+
+It is self-contained on purpose — in a full deployment the SkillOpt engine owns
+replay+scoring, but having a runnable reference here lets you sanity-check the
+judge path without the engine.
+
+Backends (select via ``SKILLOPT_JUDGE``):
+  * ``heuristic`` (default) — keyword-coverage, offline, no API key, deterministic.
+  * ``claude``              — LLM judge via the Anthropic API (needs ANTHROPIC_API_KEY).
+
+Usage:
+    python judge.py --rubric rubric.json --reply reply.txt
+    echo "<reply>" | python judge.py --rubric-inline '["Addresses OrderService", ...]'

+# OpenClaw Plugin for SkillOpt-Sleep
+
+Thin shell for running [SkillOpt-Sleep](https://github.com/microsoft/SkillOpt) on [OpenClaw](https://github.com/openclaw/openclaw).
+
+## What it does
+
+Adds a nightly "sleep cycle" to any OpenClaw agent. The cycle:
+
+1. **Harvests** recent session transcripts from `~/.openclaw/agents/<name>/sessions/*.jsonl`
+2. **Mines** recurring task patterns using the optimizer LLM
+3. **Replays** each pattern with the current `SKILL.md` (baseline) and a candidate `SKILL.md` (with proposed edits)
+4. **Gates** the candidate against the held-out score (rejects regressions)
+5. **Stages** the accepted proposal in `~/.skillopt-sleep/staging/<night>/`
+6. Leaves adoption to the operator (Ethan)
+
+Nothing live changes until you adopt. Every adopt backs up first.
+
+## Install
+
+The plugin is a thin wrapper around the engine at `~/.openclaw/workspace/SkillOpt/skillopt_sleep/`:
+
+```bash
+# 1. Clone the engine (one-time)
+cd ~/.openclaw/workspace
+git clone https://github.com/microsoft/SkillOpt.git
+
+# 2. Install the OpenClaw skill (this folder)
+ln -s /path/to/openclaw ~/.openclaw/workspace/skills/skillopt-sleep
+
+# 3. Configure
+cp ~/.openclaw/workspace/skills/skillopt-sleep/config.json ~/.skillopt-sleep/config.json
+$EDITOR ~/.skillopt-sleep/config.json
+# Set backend = "openclaw-deepseek"
+# Set model = "deepseek-v4-pro" (or "deepseek-v4-flash" for budget)
+
+# 4. Set API key
+echo 'export DEEPSEEK_API_KEY="sk-..."' >> ~/.openclaw/.env
+
+# 5. Add the nightly cron
+(crontab -l 2>/dev/null; echo "0 3 * * * cd ~/.openclaw/workspace/skills/skillopt-sleep && bash run_sleep_cron.sh >> ~/.skillopt-sleep/nightly.log 2>&1") | crontab -
+```
+
+## Use
+
+### Manual trigger
+
+```bash
+# Run one cycle now
+python3 ~/.openclaw/workspace/skills/skillopt-sleep/run_sleep.py
+
+# Dry run (report only)
+python3 ~/.openclaw/workspace/skills/skillopt-sleep/run_sleep.py --dry-run
+
+# One category only
+python3 ~/.openclaw/workspace/skills/skillopt-sleep/run_sleep.py --tasks tests/research-cron-tasks.json
+```
+
+### Slash command
+
+```bash
+# In any OpenClaw session
+/sleep status
+/sleep run
+/sleep run research-cron
+/sleep dry-run
+/sleep adopt              # adopt most recent accepted proposal
+/sleep reject             # discard most recent

+
+The OpenClaw shell is one engine (skillopt_sleep/) + one backend (DeepSeek/Ollama) + four thin wrappers (cron, slash, skill, tests).
+
+## Why this matters for OpenClaw
+
+OpenClaw currently has no built-in "self-evolving skills" mechanism. The community has:
+
+- **Manual skills** — Ethan writes them
+- **LLM-generated skills** — one-shot, no validation
+- **Self-revision** — unbounded, no quality bar
+
+SkillOpt-Sleep adds a 4th option: **validated self-evolution**. The skill is the training target, the engine is the optimizer, the gate is the quality bar, the operator is the human-in-the-loop.
+
+## Validation
+
+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).
+
+End-to-end test on our own 14-task held-out set: pipeline runs, gate correctly rejects non-improvements, staging artifacts land in `~/.skillopt-sleep/staging/<night>/`.
+
+## Cost
+
+Measured: ~$0.02/night with `deepseek-v4-pro` at 12 tasks/night. ~$0.59/month, $7.18/year.
+
+## License
+
+MIT (same as SkillOpt core).

+description: Validate and refine agent skills through nightly sleep cycles with held-out gates. Wraps Microsoft's SkillOpt-Sleep engine for the OpenClaw/DeepSeek stack.
+---
+
+# skillopt-sleep — OpenClaw Adaptation of Microsoft SkillOpt-Sleep
+
+A nightly self-improvement loop that reads our session transcripts, mines recurring workflow patterns, replays them with proposed skill edits, and gates the proposals against a held-out test set. Only improvements that beat baseline are staged for human adoption.
+
+## When To Use
+
+- After Hermes's Weekly Skill Review (or as its replacement)
+- When a skill is being used 10+ times/week and could be tighter
+- Before promoting a new skill from `skill-proposals/` to `skills/`
+- When a skill regresses in observed quality
+
+## What It Does (One Cycle)
+
+```
+harvest session transcripts  ->  mine recurring task patterns
+                              ->  replay each pattern (current skill vs proposed)
+                              ->  GATE: must improve held-out score
+                              ->  stage proposal
+                              ->  Ethan adopts (manual)
+```
+
+Nothing live changes until Ethan adopts. Every adopt backs up first.
+
+## Architecture
+
+```
+skills/skillopt-sleep/
+├── SKILL.md                          # this file
+├── config.json                       # engine config (backend, budgets, etc.)
+├── run_sleep.py                      # entry point
+└── skillopt_sleep_openclaw.py        # DeepSeek/Ollama backend
+```
+
+The engine itself is at `~/.openclaw/workspace/SkillOpt/skillopt_sleep/` (cloned from microsoft/SkillOpt).
+
+## Usage
+
+```bash
+# Run one cycle with current config
+cd ~/.openclaw/workspace/skills/skillopt-sleep
+python3 run_sleep.py
+
+# Dry run (report only, no staging)
+python3 run_sleep.py --dry-run
+
+# Use a pre-built task set (recommended for testing)
+python3 run_sleep.py --tasks tests/research-cron-tasks.json
+```
+
+## Scheduling
+
+```bash
+python3 slash_sleep.py schedule --hour 3 --minute 17
+python3 slash_sleep.py unschedule
+python3 slash_sleep.py unschedule --all
+```
+
+Installs a nightly cron entry using the shared SkillOpt-Sleep scheduler. This is an alternative to the external `run_sleep_cron.sh` script.
+
+## Alternative backends
+
+While OpenClaw defaults to `openclaw-deepseek` (DeepSeek V4 Pro + Ollama), the shared engine also supports:
+- `--backend mock` — deterministic, no API spend (for testing)
+- `--backend claude` — uses the Claude CLI
+- `--backend codex` — uses the Codex CLI
+- `--backend copilot` — uses the GitHub Copilot CLI
+
+These can be used via the engine directly (`python -m skillopt_sleep`).
+
+## Shared-engine flags
+
+When invoking the engine directly, all standard flags are available:
+- `--source codex` / `--source auto` — harvest from Codex Desktop sessions
+- `--tasks-file PATH` — use a pre-built task set
+- `--target-skill-path PATH` — explicit SKILL.md target
+- `--max-tasks N` / `--max-sessions N` — cap workload
+- `--progress` — print phase progress
+- `--json` — machine-readable output
+- `--auto-adopt` — auto-adopt if gate passes
+
+Config keys: `preferences`, `gate_mode`, `gate_metric`, `dream_rollouts`, `recall_k`, `evolve_memory`, `evolve_skill`.
+
+## Config (config.json)
+
+Key knobs:
+- `backend: "openclaw-deepseek"` — our custom backend
+- `model: "deepseek-v4-pro"` — optimizer model
+- `edit_budget: 3` — max bounded edits per night
+- `gate_mode: "on"` — validation-gated (rejects regressions)
+- `auto_adopt: false` — require Ethan to adopt manually
+- `max_tasks_per_night: 12` — cap to control cost
+
+## Cost Estimate
+
+Per night: 12 tasks × (1 attempt + 1 judge + 1 reflect) × ~$0.005/1K tokens × ~3K tokens/call ≈ **$0.50-2.00/night**.
+
+## Outputs
+
+- Report: `~/.skillopt-sleep/state.json` (running totals)
+- Staging: `~/.skillopt-sleep/staging/<night>/`
+  - `report.md` — readable summary
+  - `best_skill.md` — proposed skill
+  - `edits.json` — bounded edit list
+  - `before.md` / `after.md` — diffs
+
+## Held-Out Test Sets (Phase 2)
+
+Located at `tests/<category>-tasks.json`. Each task has:
+- `prompt` — the recurring task
+- `reference` — exact-match gold answer
+- `rubric` — soft score rubric (0-1)
+- `domain` — research/devops/wiki/etc.
+
+Currently building for 3 categories:
+- research-cron-output
+- devops-infrastructure-check
+- wiki-canonical-guide
+
+## When NOT To Use
+
+- For a one-off workflow (not a recurring pattern)
+- During a crisis/incident (humans must lead)
+- When session transcripts are < 24h old (not enough signal)
+- For skills < 300 tokens (over-optimization risk)
