Does this skill support FastAPI?

Yes, it specifically includes patterns for navigating and managing Python-based API endpoints typically used with frameworks like FastAPI.

How does this skill help with API type safety?

It provides a map of where database types and frontend TypeScript definitions reside, allowing Claude to synchronize models between the backend and frontend.

Is this skill useful for database integration?

Yes, it includes references to Supabase database types, ensuring that API contracts reflect the underlying data structure.

Can I use this for debugging 404 errors?

Yes, it helps identify discrepancies between backend route definitions and frontend service calls to pinpoint where the integration is breaking.

API Development

Coordinates frontend-backend API integration by managing endpoint definitions, request/response types, and route configurations.

About

The API Contracts & Integration skill serves as a comprehensive framework for managing the communication layer between frontend and backend services. It provides Claude with specific guidance on navigating FastAPI endpoints, TypeScript API clients, and Supabase database types to ensure cross-stack consistency. By standardizing how API routes, middleware, and integration tests are accessed and modified, this skill helps developers eliminate type mismatches, resolve 404 errors, and maintain a robust data flow across the entire application stack.
