harvest

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.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by huytieu on GitHub. Read the source before you install it.

Installation

Install the Harvest AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/huytieu/COG-second-brain.git /tmp/COG-second-brain
mkdir -p .claude/skills
cp -r /tmp/COG-second-brain/skills/harvest .claude/skills/harvest

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Harvest in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Harvest on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Harvest is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

/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)

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.

Lead (Opus) presents to the user:

Promote list → approve which become 05-knowledge/lizard/YYYY-MM-DD-<slug>.md
Fold list → approve inline edits to existing notes
Skill patches → approve CLAUDE.md / SKILL.md diffs

Only after approval: write durable files. Update 05-knowledge/lizard/index.md.

Phase 3 — Retro line

One line to 01-daily/journal/<today>.md:


Harvest: <n> staged, <m> promoted, <k> folded

Rules

Harvest is advisory. It never auto-writes 05-knowledge.
Contradictions with existing knowledge → flag both, ask the user.
Pair with /memory-hygiene monthly for environment-dependent facts in ~/.claude/.../memory/.

Nightly enhance (optional)

If you want harvest to run unattended, schedule a job that invokes the skills in this order. There is nothing to install first, since COG ships no hooks.


/memory-hygiene
/harvest promote     # only if the staging file is non-empty
/content-factory     # only if scheduled

Frequently asked questions

What does the Harvest AI skill do?

Why use Harvest on TypingMind?

Because you install it once and use it with any model. Harvest is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Harvest in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/huytieu/COG-second-brain/tree/main/skills/harvest. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Harvest?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Harvest?

As many as you like. As long as a model supports skills, you can use Harvest with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Harvest AI skill free?

Yes. It is published on GitHub by huytieu under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
