skillopt-sleep

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 → TaskRecords (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 /skillopt-sleep command. Under the hood it calls the bundled runner:

"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" status                       # what's happened
"${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.

Scheduling

"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" schedule --project "$(pwd)" --hour 3 --minute 17
"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" unschedule --project "$(pwd)"

Installs a nightly cron entry. unschedule --all removes every managed entry.

All CLI flags

Flag	Default	Description
--project PATH	cwd	Project directory to evolve
--scope all|invoked	invoked	Harvest scope
--backend mock|claude|codex|copilot	mock	Replay backend (mock = no API spend)
--model NAME	backend default	Override the model used for replay
--source claude|codex|auto	claude	Transcript source
--lookback-hours N	72	Harvest window
--max-sessions N	unlimited	Cap harvested sessions
--max-tasks N	40	Cap mined tasks
--target-skill-path PATH	auto	Explicit SKILL.md to evolve
--tasks-file PATH	—	Reviewed TaskRecord JSON (skip harvest)
--progress	off	Print phase progress to stderr
--auto-adopt	off	Auto-adopt if gate passes
--edit-budget N	4	Max bounded edits per night
--json	off	Machine-readable JSON output

Config keys (~/.skillopt-sleep/config.json)

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.

Memory consolidation

The sleep cycle can consolidate both:

• SKILL.md — the managed skill file (bounded edits: add/delete/replace)
• CLAUDE.md — the project memory (same bounded edits)

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.

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

# 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
