| name | skillopt-sleep |
| description | Use when the user wants the dsh agent to self-improve from past usage, asks about a nightly/offline 'sleep' or 'dream' cycle, skill/memory 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 background self-optimization. Drives the skillopt_sleep engine through the skillopt_* tools: harvest past sessions -> mine recurring tasks -> replay via a selected backend -> consolidate validated skills behind a held-out gate. |
SkillOpt-Sleep: usage-driven self-evolution for the dsh agent
SkillOpt-Sleep is Microsoft's SkillOpt
deployment-time companion engine: it reviews your past sessions (harvest), mines
recurring tasks (mine), replays them through a selected backend (replay), and
consolidates what it learns into skill documents behind a held-out validation
gate (consolidate).
This skill drives the engine through the 7 skillopt_* tools exposed by the
dsh-skillopt plugin. The default mock backend makes no model calls, which is
useful for verifying the plumbing; a real backend consumes your API budget.
When to use
- "make my agent better the more I use it" / "learn my preferences across sessions"
- a one-off offline self-evolution / sleep / dream run (immediate or scheduled)
- review past sessions/trajectories and distill recurring tasks
- consolidate feedback into
AGENTS.md / SKILL.md / managed skills
- schedule (cron) the cycle, or adopt a staged proposal
The cycle (six stages)
- Harvest — read-only scan of supported local session records → digests
- Mine — digests → recurring task records (intent + outcome labels + checkable refs)
- Replay — re-run tasks under the current skill+memory with the selected backend → (hard, soft) scores
- Consolidate — reflect on failures → propose bounded edits → validation gate on a held-out slice (default: accept only on strict improvement)
- Stage — write accepted proposals to
<project>/.skillopt-sleep/staging/<timestamp>/. Live files are unchanged. A rejected run still has a report but no proposal files.
- Adopt — explicit (or operator-configured
--auto-adopt) copies staged files over live ones, backing up first.
Driving it
Prefer the tools over hand-editing files:
| Tool | Behavior |
|---|
skillopt_status | state, engine availability, latest staged proposal & report |
skillopt_dry_run | full preview (harvest+mine+replay), stages nothing |
skillopt_run | full cycle, stages a proposal (live files unchanged by default) |
skillopt_adopt | apply latest staged proposal (with backup) — the live-change boundary |
skillopt_harvest | read-only show/export of mined tasks |
skillopt_schedule / skillopt_unschedule | install/remove the nightly cron entry for this project |
Typical flow:
# 1. check state (default mock backend, zero cost)
skillopt_status
# 2. preview the cycle
skillopt_dry_run project=<dir> source=<claude|codex|…>
# 3. real run (consumes the selected backend's API budget)
skillopt_run project=<dir> backend=<codex|claude|…> preferences="Prefer pytest; keep commits imperative."
# 4. review the report, then adopt
skillopt_adopt project=<dir>
# 5. schedule nightly at 03:17
skillopt_schedule project=<dir> hour=3 minute=17 backend=<codex>
Parameters
| Parameter | Default | Meaning |
|---|
project | config or cwd | project directory to evolve |
backend | mock | mock|claude|codex|copilot|cursor|pi|opencode|handoff|azure_openai (mock = no model calls) |
source | config | transcript source: claude|codex|copilot|cursor|pi|opencode|auto |
model | backend default | replay model override |
maxTasks | 40 | mined-task cap |
preferences | empty | house rules for the reflection prior (e.g. "always use async/await") |
Configuration (cordis.yml / bundle patch)
- insert:
- id: skillopt
name: './src/index.js'
config:
backend: codex
project: /path/to/project
preferences: 'Always use async/await'
autoAdopt: false
Advanced engine keys go in ~/.skillopt-sleep/config.json:
gate_mode (on/off), gate_metric (hard/soft/mixed), gate_no_regression,
dream_rollouts, recall_k, evolve_memory / evolve_skill.
Hard rules
- Never hand-edit
AGENTS.md / SKILL.md around skillopt_adopt; let the
engine's explicit adopt (or operator-configured --auto-adopt) apply the
staging manifest, backing up live files first.
- Harvest is read-only;
mock replay has no side effects.
- Real backends send truncated transcript excerpts and derived tasks to the
selected provider for mining/replay/judging/reflection. For sensitive
sessions, export tasks first (
skillopt_harvest output=<file>), redact, set
the top-level "reviewed" to true, then replay with --tasks-file; real
backends refuse unreviewed task files.
- Show the user the held-out baseline → candidate score and the exact
proposed edits before suggesting adoption. Evidence before adoption.
Validate / demo (no API spend)
pip install skillopt
python -m skillopt_sleep.experiments.run_experiment --persona researcher --assert-improves
Deterministic synthetic demo: the score rises and the gate blocks a regression.
It validates the mechanism, not effectiveness on your own tasks.
