API Contract Safety & Consistency
Enforces strict frontend-backend API contract standards to prevent response shape drift and ensure consistent data structures across services.
This skill provides a robust framework for managing API contracts between frontend and backend systems, ensuring that HTTP/JSON interfaces remain consistent and predictable. It guides Claude to prioritize root-cause fixes in the backend over temporary frontend workarounds, standardizes pagination and response wrappers, and implements clear exit strategies for legacy compatibility layers. By focusing on real-time data verification over static type definitions, it prevents technical debt caused by 'silent' compatibility code and ensures that list, detail, and filter interfaces adhere to a unified communication protocol.
