- description
- Nightly maintenance for the compound loop — review each project STATE.md, promote only verified lessons to durable rules, keep MEMORY.md under budget, and log a short digest. Conservative and local only — never edits source, never pushes, never messages anyone. Schedule it to run nightly (see Scheduling).
# Compound nightly distill
Steady, unattended compounding. This is the maintenance half of the loop: it does not write
code — it promotes already-verified outcomes into durable rules and keeps memory healthy.
## Procedure
1. **Find state files:**
`find . ~ -maxdepth 3 -name STATE.md -not -path '*/node_modules/*' -not -path '*/.git/*'`
(scope to your project roots as you prefer).
2. **Promote verified lessons only.** For each `STATE.md` with real content, review
**Open failures**. Promote one to a generalized rule under **Verified facts** /
**General rules** *only* when there's concrete evidence the fix holds (tests passing, a
merged commit). Never invent a lesson. If a fix looks done but you can't confirm it, leave
it and note it under **Waiting for human**. Update **Last session** with the date.
3. **Memory hygiene.** If `MEMORY.md` exceeds ~200 lines / 25 KB, consolidate it: merge
duplicate rules, drop stale entries, and push detail into per-topic files, so the index
still auto-loads into subagents. (If a memory-consolidation skill is available in your
setup, you may use it instead.)
4. **Digest.** Append one dated line of what changed to a log (e.g.
`~/.claude/logs/compound-nightly.md`). If nothing to do, log "idle — no history yet".
## Guardrails
- LOCAL ONLY: no source edits, no `git push`, no external messages.
- Conservative: promote on evidence, not optimism. Churn is failure, not progress.
## Scheduling
Run nightly via Claude Code scheduled tasks or `/schedule`. Example cron (local time):
`41 3 * * *`. Keep the prompt self-contained — scheduled runs start fresh with no memory of
prior sessions, so point them at this skill explicitly.
