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

1. Extracts trigger keywords from each skill's description field
2. Filters common stop words (~60 words)
3. Compares all skill pairs using Jaccard similarity
4. 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
