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
