API Contract Validation
I'll analyze your API contracts for breaking changes, compatibility issues, and schema validation.
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
