Implement consumer-driven contract testing with Pact-JS (v16). Covers consumer test writing, broker-driven provider verification, Pact Broker setup, can-i-deploy as a deployment gate, webhook-triggered verification, pending pacts, and schema-first vs consumer-first approaches (OpenAPI/Ajv, Schemathesis). Use when: "contract test," "Pact," "consumer-driven," "API contract," "provider verification," "can-i-deploy." Not for: stubbing or mocking a dependency to isolate a test — use…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> A provider renames a response field. Both services pass their own unit tests, and the mismatch only surfaces in production when the consumer's frontend breaks. Contract testing catches that in CI: the consumer declares exactly what it needs, the provider verifies it can deliver, and `can-i-deploy` blocks the deploy until the broker confirms both sides are compatible. This skill produces Pact consumer tests, broker-driven provider verification, and the deployment gate that ties them together — so services can be deployed independently without a shared integration environment. </objective> ## Discovery Questions Check `.agents/qa-project-context.md` first — if it exists, use it and skip anything already answered there. Then: 1. **Architecture:** Microservices, monolith with separate consumers (mobile/SPA), or BFF pattern? Contract testing matters most when teams deploy independently. 2. **Who owns the contract?** Consumer-driven (consumers define what they need) or provider-driven (provider publishes a spec)? Most teams benefit from consumer-driven. …

How to install
mdr add petrkindlmann/qa-skills/contract-testing@sha256:fc69dd9b0e7228f2The line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
