Duplicate Detection
Find skills with overlapping functionality using keyword similarity analysis.
How to Run
bash ~/.claude/skills/skills-janitor/scripts/detect_dupes.sh
How It Works
- Extracts trigger keywords from each skill's description field
- Filters common stop words (~60 words)
- Compares all skill pairs using Jaccard similarity
- Flags pairs with >30% keyword overlap
Output
[72%] marketing-copywriting <-> marketing-copy-editing
Scopes: user, user
Shared keywords: copy, editing, marketing, write
[45%] seo-audit <-> marketing-seo-audit
Scopes: project, user
Shared keywords: audit, seo, ranking
After Finding Duplicates
- Review each pair - some overlap is intentional (e.g., copywriting vs copy-editing)
- Plugin skills should NOT be edited (changes get overwritten)
- For user-scope duplicates, suggest which to keep and why
- Ask for confirmation before any removal
