What problem does it solve?

This skill automates the generation of deterministic API contract tests to validate API endpoints against the OpenAPI spec and frontend TypeScript types, reducing drift and speeding up integration readiness.

Core Features & Use Cases

  • Automated contract test generation: Create pytest tests for API endpoints or Vitest tests for frontend calls that verify request/response shapes against the OpenAPI schema and generated clients.
  • Drift detection and fast feedback: Compare implementation, OpenAPI, and frontend types to fail early on mismatches.
  • End-to-end workflow: Reads handlers, OpenAPI spec, and client models to produce test files under api/tests/contracts/ or frontend/tests/contracts/.

Quick Start

Provide an endpoint (e.g., GET /v1/opportunities/search) and the target side (api or frontend) to generate the corresponding contract test file.
