Master API Design: AI Agent Skill for Seamless Coding

Enhance your development workflow with the "Master API Design" skill, a cutting-edge AI agent capability designed for developers and teams using Claude Code, Cursor, or Codex. This skill empowers you to craft stable, well-documented interfaces, streamlining communication between code pieces and minimizing the risk of misuse. Whether you're building new REST or GraphQL endpoints, defining module boundaries, or creating component props, this skill ensures that your interfaces stand robust and user-friendly.

What this skill does

• Guides you in designing new API endpoints and defining type contracts that are both reliable and maintainable.
• Helps establish clear frontend/backend interfaces and module boundaries that facilitate seamless integration and collaboration between teams.
• Ensures even database schemas are thoughtfully designed, impacting the shape and stability of your APIs.
• Assists in changing existing public interfaces responsibly, considering any dependencies users may have, in line with Hyrum's Law.
• Encourages the practice of planning for API deprecation right from the design phase, to preemptively manage future changes.

Use cases

• Designing robust APIs: For teams launching new services, ensure your REST and GraphQL endpoints are both innovative and dependable.
• Collaborative development: Define clear contract boundaries between teams to streamline multi-team software projects.
• Component development: Design component prop interfaces that adhere to best practices in API design, preventing common pitfalls.
• Schema management: Establish database schemas that naturally inform and support API design efforts.
• Interface modification: Safely update public interfaces while respecting Hyrum's Law and minimizing user disruption.
