| description | Find external skills from public registries, GitHub repos, and official skill collections, then evaluate them for quality, licensing, and fitness for adoption. Use when looking for existing skills before building from scratch, evaluating external skill quality, or migrating community skills into a local library. Do not use when building a novel skill with no external precedent or for quick one-off evaluation (just read the skill directly). |

Community Skill Harvester
Harvests skills from public registries and evaluates them for adoption.
Procedure
1. Search for relevant skills
Search these sources in order:
gh search repos --topic agent-skills --limit 20 --json fullName,description,stargazersCount
gh api repos/anthropics/skills/contents/skills --jq '.[].name' 2>/dev/null
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
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
