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.
