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 Strategy

Target Reduction: 50% (3,000-5,000 → 1,000-2,500 tokens)

This skill uses aggressive optimization through checksum-based caching, schema diffing, and early exit patterns to minimize token usage while providing comprehensive API contract validation.

Optimization Patterns Applied

1. OpenAPI Schema Caching (60% reduction)
   • Cache parsed OpenAPI/Swagger schemas with checksums
   • Detect changes via file checksums before expensive parsing
   • Reuse cached schemas across validations
   • Share contract cache with /api-test-generate, /api-docs-generate
