Skillopt Sleep

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

├── SKILL.md                          # this file
├── config.json                       # engine config (backend, budgets, etc.)

└── skillopt_sleep_openclaw.py        # DeepSeek/Ollama backend

The engine itself is at ~/.openclaw/workspace/SkillOpt/skillopt_sleep/ (cloned from microsoft/SkillOpt).

Usage

# 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

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//
• 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/-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)
