API Contract Regression Guard is a specialized capability for Claude Code that automates the detection of breaking changes across diverse API protocols by comparing current schema definitions against established baselines. It streamlines the software development lifecycle (SDLC) by identifying removed endpoints, field type mismatches, and schema violations early, while integrating directly with consumer contract testing frameworks like Pact and Spring Cloud Contract. This skill provides engineering teams with detailed compatibility reports, impact analysis for specific consumers, and enforced semantic versioning logic to maintain stable integrations for downstream users.
