# API Contract Testing — validate an OpenAPI spec against expected endpoints Load this skill when you need to **check that a running API (or a spec on disk) actually matches the contract it promises**. It is the verification counterpart of `api-doc-generator` (which *writes* the spec) and `test-generator` (which *writes* the tests): this skill *checks* the spec against a manifest of expected endpoints and, optionally, against the live API. The tool is **pure Python 3 stdlib** — no PyYAML, no requests, no pip install. It reads an OpenAPI 3.x document from a file (`.json` or `.yaml`) or a URL, enumerates every declared operation (under `paths` and `webhooks`), checks the spec's internal consistency, and compares it against an optional manifest file. In `--offline` mode it never touches the network; in live mode it probes each manifest endpoint over HTTP and compares the actual status code with the expected one. ## Triggers Load this skill when the request matches any of these (EN / RU): - "api contract testing", "contract test", "check the API against the spec" - "validate openapi spec", "spec vs manifest", "endpoint coverage" - "проверь контракт API", "тест контракта", "сверь спецификацию с API" - "валидация openapi", "проверка эндпоинтов", "контрактное тестирование" - "does the API match the spec", "missing endpoints", "expected status codes" --- ## The api_contract.py script `scripts/api_contract.py` — pure Python 3 stdlib (no dependencies). | Mode | Command | |---|...
