# 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. It requires **no weight training** and adds no separate optimization loop to normal agent requests. > **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/`](https://github.com/microsoft/SkillOpt/tree/main/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). > **Data boundary.** Harvesting is local and read-only. The `mock` backend makes no > provider calls. A real backend, however, sends truncated excerpts from harvested > sessions and derived tasks to the provider you select for mining, replay, judging, > and reflection. Outbound prompts are not currently guaranteed to be secret-free; > review your transcript source and provider policy before running on sensitive > projects. For a reviewable workflow, harvest to a task file, inspect/redact it, mark > it `"reviewed": true`, and then replay that file with the real backend. ## 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; stages 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 ``` > **Version note.** This page tracks `main`. PyPI 0.2.0 provides the base > commands above. Sleep handoff, non-Azure OpenAI-compatible endpoints, and > `--preferences` landed later and require a source install from `main` until > the next release. The per-agent integrations below still come from the repo; the CLI above is the standalone, pip-only way to run a cycle. Claude Code, Codex, Copilot, and Devin wrap the shared engine. OpenClaw is a separate reference adaptation and has its own setup. One engine, thin per-agent shells (see [`plugins/`](https://github.com/microsoft/SkillOpt/tree/main/plugins)): | Platform | Folder | Install | |---|---|---| | **Claude Code** | [`plugins/claude-code`](https://github.com/microsoft/SkillOpt/tree/main/plugins/claude-code) | `/plugin marketplace add ./plugins/claude-code` → `/skillopt-sleep` | | **Codex** | [`plugins/codex`](https://github.com/microsoft/SkillOpt/tree/main/plugins/codex) | `bash plugins/codex/install.sh` → `skillopt-sleep` skill | | **Copilot** | [`plugins/copilot`](https://github.com/microsoft/SkillOpt/tree/main/plugins/copilot) | register `plugins/copilot/mcp_server.py` as an MCP server | | **Devin** | [`plugins/devin`](https://github.com/microsoft/SkillOpt/tree/main/plugins/devin) | register `plugins/devin/mcp_server.py` as an MCP server | | **OpenClaw** | [`plugins/openclaw`](https://github.com/microsoft/SkillOpt/tree/main/plugins/openclaw) | adapt the reference wrapper and paths for your installation | To use DeepSeek, vLLM, Ollama, or another Chat Completions server, see **[OpenAI-compatible endpoints](openai-compatible-endpoints.md)**. That guide also documents the separate HTTPS-only boundary for Azure managed-identity credentials. 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: **Controlled experiment recipe (not the shipping CLI defaults).** 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). The experiments use the shipped consolidation and gate components, while the nightly CLI and benchmark harnesses remain separate entry points. 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. ## Learn more See the [SkillOpt documentation index](../index.md), the [CLI reference](../reference/cli.md), and the integration-specific READMEs under [`plugins/`](https://github.com/microsoft/SkillOpt/tree/main/plugins).
