What Harvest does

Harvest captures session corrections, stable facts, process lessons, and skill gaps for later human review. Use it at the end of a session or from a staging hook when you want to propose durable knowledge without writing it automatically.

Harvest is cataloged under AI Engineering on DirSkills. Harvest comes from a repository tagged agent-loop, agent-plugins, agent-skills, agentic and ai-agents.

Documentation

README

Excerpt

/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:

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

Each one is a separate skill with its own page in this directory, installs the same way Harvest does, and is maintained by huytieu in that same repository. The rest of the collection is listed on the huytieu/COG-second-brain page.
How does Harvest compare to other AI Engineering skills?
Harvest ranks #1468 by stars among the 2451 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Harvest against them.
