If curated lists are unavailable, search GitHub directly. Prioritize repos updated within 6 months with meaningful star counts.
Skip: No SKILL.md, abandoned (no commits in 1+ year AND unresponsive), <10 stars (unless from trusted source), duplicates already-installed skill.
Never auto-execute downloaded scripts.
Before installing:
- Check for existing skill with same name
- If conflict: ask user to overwrite, rename, or skip
After downloading:
- Validate SKILL.md parses without YAML errors
- Confirm required frontmatter (name, description, triggers) exists
- Test with
/skill <name>or a natural trigger phrase
If install fails: Remove any partially downloaded files and report the specific failure.
Fetch skill, run security review if scripts present, validate format, install to skills directory, verify it loads.
List installed skills from .claude/skills/, check source repos for updates,
identify unused skills for removal.
