Arguments: `$ARGUMENTS` - API spec paths, comparison targets, or validation focus ## Token Optimization **Expected range**: 200–500 tokens (initial), 50–100 tokens (cache hit) **Caching**: Caches schema checksums in `.claude/cache/api/` for 7 days. Invalidated when schema files change. **Early exit**: Returns immediately if schema checksums match cached values. **Patterns used**: Grep-before-Read, early exit, checksum-based caching, git diff scope default
