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
