Capture durable session learnings, stage for human promotion to 05-knowledge/lizard, and propose skill/CLAUDE.md patches. Triggered by /harvest, SessionEnd hook staging, or nightly enhance. Never writes durable knowledge without your approval.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# /harvest — session learning capture

Adapted from dwarves-kit `harvest` hook + vault lizard pipeline. Prevents tacit knowledge dying in the transcript.

## Triggers

- `/harvest` — manual end-of-session
- `/harvest promote` — curate staging → lizard drafts (uses harvest-curator)
- Staging file written by `stop` hook (`.cursor/hooks/harvest-stager.sh`)

## Phase 1 — Collect (automatic or manual)

Scan the current session for:

1. **Corrections you made** ("no, actually X", rejected deliverables)
2. **New stable facts** (IDs, URLs, decisions) not yet in 05-knowledge
3. **Process lessons** (what worked, what failed, friction)
4. **Skill gaps** (something that should be a Verify step or CLAUDE.md rule)

Append to `04-projects/harness/harvest/staging-<YYYY-MM-DD>.md`:

```markdown
## <HH:MM> — <trigger>
- type: correction|fact|process|skill-gap
- source: <file or "session">
- text: <one paragraph max>
- proposed_home: <path or "new lizard note">
```

Dedup: skip if same fact already in staging today or in 05-knowledge.

## Phase 2 — Curate (`/harvest promote`)

Spawn `harvest-curator` (Sonnet). It writes `/tmp/harvest-curate-<date>.md`.

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/harvest@sha256:bd04412e64fe52d5

The line at the top of this page pins the label git:20260825.623ed00, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
