API Contract Enforcer
Validates that code changes do not silently break API contracts, checking schemas, status codes, and backward compatibility with severity-rated breaking-change reports. Useful for microservices teams preventing cross-service regressions. Backend engineers shipping API changes, platform teams owning microservice contracts, SDK maintainers managing versioning, API-first companies with external consumers. A silent breaking change — a renamed field, a dropped nullable, a tightened validation — cascades through consumer services and client apps and surfaces hours later as pager alerts. Contract testing frameworks exist, but they require setup most teams do not invest in until after the first costly incident. A structured enforcer runs against any PR that touches an API surface and flags breaking changes before merge.
