What kind of errors can this skill detect?

It identifies missing operation IDs, invalid schema references, missing response definitions, and duplicate identifiers that could cause issues in production.

Can I use this for very large OpenAPI files?

Yes, the skill includes optimized commands that pipe output to grep or tail, making it easier for Claude to process results without exceeding context limits.

How does this skill help with API development?

It uses the Speakeasy CLI to scan your OpenAPI files for errors that might break SDK generation, ensuring your API contracts are robust and standardized.

Do I need the Speakeasy CLI installed?

Yes, this skill functions as an interface for the 'speakeasy lint' command, so having the Speakeasy CLI installed in your environment is required.

API開発

Validates OpenAPI specifications using Speakeasy to ensure contract compliance and high-quality SDK generation.

概要

This skill integrates Speakeasy's powerful linting engine into Claude's workflow, allowing developers to automatically detect and resolve issues within their OpenAPI definitions. It streamlines the API development process by identifying critical errors that block SDK generation, surface warnings for potential runtime issues, and providing hints for industry best practices. Whether you are debugging broken references or preparing a contract for production, this skill ensures your API documentation is accurate, type-safe, and ready for downstream automation.
