Can I manage authentication with this skill?

Yes, it includes capabilities for defining standardized authentication schemes, such as OAuth2 or API keys, and security requirements.

Is this skill ready to use?

This skill is currently a documented stub within the VibeKit repository, which preserves the planned structure for these design-first API capabilities.

What is a design-first API approach?

Design-first means writing the API specification (like OpenAPI) before writing any implementation code to ensure a consistent contract and better team collaboration.

Does this skill support OpenAPI 3.1.0?

Yes, this skill is specifically designed to leverage the latest features and compliance standards of OpenAPI 3.1.0 for modern API development.

How does this help with microservices?

It ensures consistency across different services by enforcing standard schema reuse, unified error response patterns, and clear versioning strategies.

API Development

Standardizes API development by generating OpenAPI 3.1.0 specifications as the single source of truth before implementation.

About

This skill empowers developers to adopt a design-first API strategy, ensuring that specifications are robust, compliant with OpenAPI 3.1.0, and serve as the authoritative contract before any code is written. By focusing on schema component reuse, authentication definitions, and consistent error handling, it helps teams avoid common anti-patterns like implementation drift and fragmented documentation, ultimately leading to more maintainable and predictable backend services within the Claude Code environment.
