Community Skill Harvester
Harvests skills from public registries and evaluates them for adoption.
Procedure
1. Search for relevant skills
Search these sources in order:
# GitHub search by topic
gh search repos --topic agent-skills --limit 20 --json fullName,description,stargazersCount
# Anthropic skills repo
gh api repos/anthropics/skills/contents/skills --jq '.[].name' 2>/dev/null
# Direct GitHub code search
gh search code "name:" --filename SKILL.md --limit 20
2. Evaluate skill quality
For each candidate, apply this checklist:
| Criterion | Check | Weight |
|---|---|---|
| Has SKILL.md | File exists | Required |
| Clear purpose | Non-vague description | High |
| Concrete procedures | Numbered steps, not platitudes | High |
| License specified | SPDX identifier present | Required |
| Active maintenance | Commits in last 6 months | Medium |
| Usage evidence | Stars, forks, downloads | Medium |
Scoring: Required checks must pass or skill is rejected. Score 0-6 on remaining criteria. Score ≥4 = adopt candidate. Score 2-3 = adapt candidate. Score <2 = reject.
3. License compatibility check
Acceptable licenses for adoption: Apache-2.0, MIT, BSD-2-Clause, BSD-3-Clause, ISC, CC0-1.0, Unlicense.
Copyleft licenses (GPL-*, AGPL-*): flag for manual review before adoption.
No license: do not import.
4. Extract patterns
Before importing, document:
- Structure patterns worth adopting
- Anti-patterns to avoid
- Adaptations needed for local conventions
5. Create import proposal
# Skill Import Proposal: [name]
## Source
- URL: [github.com/org/repo/skills/name]
- License: [SPDX]
- Quality Score: [N/6]
## Rationale
[Why adopt this skill]
## Required Adaptations
- [ ] [Adaptation 1]
- [ ] [Adaptation 2]
## Recommendation
[ADOPT | ADAPT | REFERENCE_ONLY | REJECT]
6. Execute import (if approved)
mkdir -p COPILOT/[skill-name]-COPILOT-L
# Copy and adapt SKILL.md
# Add provenance section documenting origin, license, import date, modifications
git add COPILOT/[skill-name]-*
git commit -m "feat: import [skill-name] from [source]"
Output contract
A harvest report containing:
- Sources searched and count
- Skills evaluated with scores
- Import proposals for candidates scoring ≥2
- Patterns discovered during evaluation
Failure handling
- Registry unavailable: Fall back to direct GitHub search
- License unclear: Do not import; flag for manual review
- Skill format incompatible: Extract concepts, rewrite in local format
- Quality too low: Document as "reference only", do not import
