Skill: find-duplicates

Checks words.json and all verb group files for duplicate entries before you add new vocabulary or verbs.

How to Run

Run from the project root:

# Full check — words.json + all group files
node .claude/skills/find-duplicates/scripts/find-duplicates.js

# words.json only
node .claude/skills/find-duplicates/scripts/find-duplicates.js --words-only

# Verb groups only
node .claude/skills/find-duplicates/scripts/find-duplicates.js --verbs-only

# Check one specific value before adding it
node .claude/skills/find-duplicates/scripts/find-duplicates.js --check "merg"
node .claude/skills/find-duplicates/scripts/find-duplicates.js --check "a merge"

Exit Codes

Code	Meaning
0	No duplicates — safe to add
1	Duplicates found — review before proceeding

When to Use

Run this before adding any new entry to words.json or any group-N.json. The words-and-verbs skill references this skill as the required pre-check step.

What It Checks

words.json — scans all "value" fields, case-insensitive. Reports any value that appears more than once.

group-1..4.json — scans all "infinitive" fields across all four files. Catches the same verb added to two groups by mistake.
