Quick Audit Checklist

Run this on each skill:

1. cat SKILL.md — Does it exist? Is the description clear?
2. grep -r "TODO\|FIXME\|HACK" — Any technical debt markers?
3. git log --since="30 days ago" --oneline — Any recent activity?
4. grep -i "trigger\|when to use\|example" SKILL.md — Are triggers and examples defined?
5. Check for hard-coded paths, URLs, or deprecated tool names
