qa-contract-testing

Contract testing for microservices: Pact consumer and provider tests, OpenAPI, GraphQL and Protobuf breaking-change checks, and a combined deploy gate. The gate aggregates Pact can-i-deploy, oasdiff, graphql-inspector and buf breaking into one go / no-go verdict. Agents (contract-drift-investigator, contract-test-scaffolder) trace contract drift to its source and scaffold contract tests from a spec.

What it installs

Skills (5)

  • contract-compatibility-gate

    Use when a deploy should be blocked by any incompatible API contract across protocols. Combines Pact can-i-deploy, oasdiff for OpenAPI, graphql-inspector for GraphQL and buf breaking for Protobuf into one go/no-go CI step with severity thresholds and a reason per finding.

  • graphql-schema-regression

    Use for any question about whether a GraphQL schema change is safe, including one pasted diff and a field change that broke a client: diffs schemas with graphql-inspector, classifies changes as breaking, dangerous or safe (removed fields, narrowed types, deprecated-field removal with usage checks),

  • openapi-contract-diff

    Use for any question about whether an OpenAPI or Swagger spec change breaks clients, including one pasted diff and a partner integration that broke: removed endpoints, deleted schemas, narrowed enums, changed responses. Runs oasdiff breaking, grades findings ERR, WARN or INFO and gates CI with --fai

  • pact-contract-testing

    Use whenever two services (a frontend and an API, or two microservices) keep breaking each other's API: set up Pact consumer-driven contract tests, publish pacts to a broker, verify the provider and gate deploys with can-i-deploy.

  • protobuf-compat-checking

    Use for any question about whether a .proto change is safe for consumers, including one pasted diff (a removed field, a reused field number, a changed type) and a gRPC or message-bus consumer that broke after a schema change: runs buf breaking against a past version, picks the FILE, PACKAGE, WIRE_JS

Subagents (2)

  • contract-drift-investigator

    Use proactively whenever a contract test fails or can-i-deploy says no, before opening a fix. Diffs Pact files, OpenAPI, GraphQL SDL or Protobuf against the last green baseline and says whether the provider, the schema, the consumer expectation or the test data changed, with file:line references.

  • contract-test-scaffolder

    Use proactively whenever an API (OpenAPI, GraphQL SDL, Protobuf or an existing Pact file) needs its first consumer contract tests or a new operation added to them. Emits Pact consumer expectations, Schemathesis runners or buf breaking compatibility tests.
