# Contract Diff Compare two versions of an OpenAPI/Swagger contract. ## Compare - added or removed endpoints; - HTTP method or route changes; - request fields; - required/optional changes; - type changes; - enum changes; - response fields and types; - status codes; - auth/security changes; - parameter changes; - nullable behavior. ## Classify Classify findings as Breaking, Behavioral, or Additive. When possible, search the codebase for affected endpoints/fields and list impacted consumers. ## Rules Do not overstate compatibility without inspecting actual consumers. Distinguish a contract change from confirmed application breakage. ## Output Provide summary, breaking changes, behavioral changes, additive changes, likely frontend impact, and recommended follow-up.
