How does this improve team collaboration?

By establishing a clear contract early, frontend and backend teams can work in parallel using mock servers and generated client stubs based on the approved specification.

How does it help with breaking changes?

The skill provides automated strategies for semantic versioning and uses tools like oasdiff to identify changes that could break existing consumers during the CI/CD process.

Can I use this for C# and .NET projects?

Absolutely. It includes specialized C# models and implementation patterns for managing API contracts and validation within .NET environments.

Does this skill support AsyncAPI?

Yes, it includes specific guidance, patterns, and validation strategies for both RESTful APIs (OpenAPI) and event-driven architectures (AsyncAPI).

What is contract-first design?

Contract-first design is an API development approach where you define the API specification (the contract) before writing any implementation code, ensuring stakeholders agree on the interface first.

API 개발

Designs and manages API contracts using OpenAPI and AsyncAPI specifications to ensure robust, specification-driven development.

This skill empowers developers to adopt a contract-first methodology for API development by prioritizing design over implementation. It provides comprehensive guidance on creating OpenAPI and AsyncAPI specifications, managing versioning, and detecting breaking changes before they reach production. By integrating tools for linting, mock server generation, and contract testing, this skill helps ensure that code conforms to established standards, facilitates parallel development between teams, and maintains high-quality API documentation from day one.
