Lifts a proven skill from a host repo into gbrain's bundle, genericizing it by scrubbing real names and generalizing triggers.
About
The inverse of scaffold: an editorial workflow that promotes a mature host skill upstream into gbrain so other clients can scaffold it. A developer uses it to share a battle-tested skill after a privacy-lint and conformance pass.
- Editorial genericization scrubs fork-specific names and entities
- Requires dry-run, conformance test, and explicit user approval

What it does
Lifts a proven skill from a host repo into gbrain's bundle, genericizing it by scrubbing real names and generalizing triggers.
Files
skillpack-harvest — Editorial workflow for lifting host skills into gbrain
Convention: see _brain-filing-rules.md for
file placement rules. This skill writes into gbrain's own tree, not the
brain repo's notes.
This skill is the inverse of gbrain skillpack scaffold. Scaffold ships skills downstream (gbrain → host). Harvest lifts proven patterns upstream (host → gbrain) so they become references every other client can scaffold.
Contract
A harvest is "properly done" when:
1. The host skill is mature (used in production, recent routing-eval cases pass). 2. The editorial genericization in Phase 3 has scrubbed every fork-specific reference (names, real entities, internal channels). 3. gbrain skillpack harvest --dry-run previewed the file set. 4. The real gbrain skillpack harvest <slug> --from <host> succeeded with status: harvested (no privacy-lint hits). 5. bun test test/skills-conformance.test.ts passes on the new skills/<slug>/SKILL.md. 6. The user has reviewed the diff in gbrain and explicitly approved the commit.
If any of these is incomplete, the skill is NOT yet harvested — the files may sit in gbrain's working tree, but they're not landed.
Output Format
This skill produces three artifacts in gbrain's working tree:
1. skills/<harvested-slug>/SKILL.md (and any sibling files like routing-eval.jsonl) 2. Paired source files at their mirror paths (e.g. src/commands/<slug>.ts) when the host SKILL.md declared them in frontmatter sources: 3. An updated openclaw.plugin.json with the new slug added to skills: (sorted)
The session output to the user is a one-line success summary plus a list of files written. JSON mode (--json) returns the full HarvestResult shape for machine consumption.
Anti-Patterns
- Skipping the dry-run. Always preview first. Files land in
gbrain's working tree; cleanup is a git checkout away, but you shouldn't need to.
- Trusting the linter alone. The default regex set catches the
common cases. It doesn't catch every proper noun. Phase 3 (the editorial pass) is the primary defense.
- Harvesting `--no-lint` without justification. The lint exists
for a reason. If you bypass it, document why in the commit.
- Harvesting a skill that's still in flux. Wait until the host
version stabilizes. Otherwise you'll harvest, then re-harvest, then re-harvest, and that churns gbrain's bundle for no benefit.
- Moving files instead of copying. Harvest is a copy. The host
retains its skill. Don't rm -rf the source after harvesting.
- Harvesting batch (multiple skills at once). Not supported, and
for good reason — the editorial review per skill is real work.
When to invoke
- The user developed a skill in their host fork (Wintermute, Neuromancer,
Zion, etc.) and wants other gbrain clients to be able to use it
- A skill has proven itself in production and is ready to generalize
- The user explicitly asks to "harvest" or "publish" a skill upstream
Do NOT invoke when:
- The skill is still in flux locally — let it stabilize first
- The skill references private content that can't be generalized
- The user just wants to share a one-off draft (use a gist instead)
Preconditions
Before running this skill, confirm:
1. The skill is mature. Recent routing-eval.jsonl cases pass; the skill has been used in production at least a few times.
2. The skill is generalizable. Strip-test in your head: replace every fork-specific name. Does it still make sense as a skill?
3. The user owns the gbrain checkout. The harvest writes into gbrain's working tree. They'll review and commit. Don't harvest into a checkout the user doesn't intend to commit from.
Workflow
Phase 1 — Plan
Ask the user:
- What slug should the harvested skill have? (Slugs must be kebab-case,
globally unique in the gbrain bundle.)
- Which host repo is the source? (Path to repo root, not to the skill
directory — e.g. ~/git/wintermute, not ~/git/wintermute/skills/foo.)
- Should paired source files come along? (Check the host SKILL.md's
frontmatter sources: array.)
Phase 2 — Dry-run + privacy-lint preview
Run the CLI with --dry-run:
gbrain skillpack harvest <slug> --from <host-repo-root> --dry-runThe output shows:
- Which files would land in gbrain's tree
- Whether paired sources are included
- (Implicit) The skill's frontmatter triggers — read them and check
they generalize
Do not skip the dry-run. The privacy linter only runs on a real harvest, but the dry-run preview lets you see the files before they land. Spot-check the SKILL.md and any paired source for things the linter might miss (proper nouns, internal project names, etc.).
Phase 3 — Genericization checklist (the editorial pass)
Before running the real harvest, walk the host's skills/<slug>/ files and apply this checklist. If anything matches, edit the host file FIRST, then run harvest.
1. Fork-specific names → generic phrasing
Wintermute→your OpenClaw(orOpenClaw deployment)Neuromancer,Zion,<personal-fork-name>→ same treatment- Personal first names (
garry,jane, etc.) →the user/
you / a generic placeholder
2. Real entities → placeholders
- Real people, companies, deals, funds → placeholder slugs
(alice-example, acme-example, fund-a, etc.)
- Email addresses → strip entirely OR use
example@example.com - Internal Slack channels →
#some-channelor strip - Specific tracker IDs / Linear ticket numbers → strip
3. Fork-specific conventions → references
- Mentions of
<host-repo>/docs/...files → either lift the doc
into gbrain OR replace with a generic placeholder explanation
- Mentions of
<host-repo>/skills/<other-fork-only-skill>→ either
decide to harvest that one too, or replace with a generic pattern reference
4. Triggers array generalizes
- Read every entry in frontmatter
triggers:. None should
reference the user's name, fork name, or internal tools.
- "Have garry sign off on it" → "have the user sign off on it"
5. routing-eval.jsonl examples are scrubbed
- Open
skills/<slug>/routing-eval.jsonl. Everyintentfield
gets the same scrub as triggers:.
6. Code comments + log strings
- If a paired source is going to be harvested, walk it for the
same private-pattern leaks. Comments are the most common hiding spot.
Phase 4 — Real harvest
Once Phase 3 is complete, run the real harvest:
gbrain skillpack harvest <slug> --from <host-repo-root>Default behavior:
- Path-confinement + symlink rejection at file copy
- Privacy linter runs against
~/.gbrain/harvest-private-patterns.txt
(plus built-in defaults: \bWintermute\b, email, Slack channels)
- On any match → rollback (delete the harvested files) + exit non-zero
openclaw.plugin.jsonupdated to add the slug, sorted
Outcomes:
harvested— success, manifest updated, files in gbrain's treelint_failed— privacy linter caught something. Go back to Phase 3,
scrub the host file, retry.
slug_collision— gbrain already has a skill at that slug. Either
use a different slug, or pass --overwrite-local if you really mean to replace.
Phase 5 — Verify in gbrain
After a successful harvest:
1. bun test test/skills-conformance.test.ts — confirms the new SKILL.md meets the frontmatter contract. 2. gbrain skillpack check --strict — confirms no drift between bundle and gbrain's own checkout. 3. gbrain skillpack list — confirms the slug shows up in the bundle. 4. Review the diff: cd <gbrainRoot> && git diff -- skills/<slug>/ 5. Commit the additions in gbrain (do NOT commit any leftover files in the host repo — harvest is a copy, not a move).
Phase 6 — Downstream announcement (optional)
If other gbrain clients should pick up the new skill:
- Note it in
CHANGELOG.mdunder "Skills added" for the next release - Tag the user / contributor in the PR if the skill came from
someone outside the core team
Bypass: --no-lint
The privacy linter is the safety net. The editorial pass is the primary defense. If you've completed Phase 3 thoroughly and the linter is still firing on a false positive, use --no-lint:
gbrain skillpack harvest <slug> --from <host-repo-root> --no-lintDocument the bypass in the commit message. Future maintainers should be able to see WHY the lint was bypassed (e.g. "Wintermute appears in a citation, not a real reference — verified manually").
Never bypass the linter on a casual basis. The whole point of the default-on lint is that real names occasionally slip through the editorial pass.
What harvest does NOT do
- It does NOT move files (it copies). The host's
skills/<slug>/
stays in place.
- It does NOT auto-scrub names. The editorial pass is human-driven.
- It does NOT publish to npm or a remote bundle. It writes to
gbrain's working tree; the user commits + ships via the normal gbrain release process.
- It does NOT support
--all(no batch harvest). One skill at a
time keeps the editorial review tractable.
Files this skill touches
- gbrain's
skills/<slug>/— every file in the host skill dir
(copy)
- gbrain's mirror path for declared paired sources
(e.g. src/commands/<slug>.ts if the host SKILL.md declares it in frontmatter)
- gbrain's
openclaw.plugin.json— adds the slug toskills:
