| description | Append a chronological line to brain/log.md for one operation. |
Append-only operation log. Greppable. Format: ## [YYYY-MM-DD HH:MM] <op> | <title>.
Other skills call this to record what they did, when. The log is the audit trail; brain/index.md is the catalog. Both are auto-generated artifacts (never hand-edit log.md beyond the header).
log.sh <op> "<title>"
<op>: short verb (capture, save, distill, ingest, compact, scrub, spawn, evolve, checkpoint, index).<title>: free text, single line.Examples:
log.sh save "Decided to pause Idaho-craig for Q3"
log.sh distill "gmail: 4 INBOX -> 3 brain files"
log.sh capture "Stop hook: 4 entries from claude session"
grep "^## \[" $BRAIN_DIR/brain/log.md | tail -10
grep "save" $BRAIN_DIR/brain/log.md
On first call, the file is created with a small header explaining the format.
Force a capture bypassing the throttle. Runs capture.sh with FORCE_CAPTURE=1.
Weekly compaction. Dedupe duplicate dated headers, archive entries older than 365 days, regenerate graph, verify hash.
Monthly self-improvement. Reads last 30 days of learnings + decisions, drafts ONE proposed brain edit to code/agents/_proposed/.
Regenerate brain/_graph.md from [[entity]] backlinks across brain/*.md.
Compute or verify a SHA-256 integrity hash of the stable brain corpus.
Regenerate brain/index.md catalog of all brain pages and sources.
