What is Pact in the context of this skill?

Pact is a code-first tool used for consumer-driven contract testing, allowing this skill to ensure that API providers meet the specific expectations of their consumers.

How does this benefit a microservices architecture?

It decouples the testing of services, ensuring that changes in a provider service don't inadvertently break any consumers that rely on its specific data structure.

Can this skill identify breaking changes in my API?

Yes, it validates API responses against defined contracts and OpenAPI specifications to identify backward compatibility issues before they affect production.

Do I need an existing OpenAPI file to use this skill?

While an existing OpenAPI file provides the best results for validation, the skill can also help generate contract tests based on API usage and Pact definitions.

About

This skill empowers Claude to automate the complex process of API contract testing and schema validation. By leveraging Pact for consumer-driven testing and OpenAPI for specification compliance, it helps developers ensure that providers and consumers remain in sync, preventing breaking changes before they reach production. It is particularly useful for teams managing microservices or public APIs where maintaining strict interface agreements is critical for system stability.
