Individual skill
api-test-plan
Plan tests for an API endpoint or service — functional, negative, and contract. Use when asked to test an API, write API test cases, plan REST/GraphQL endpoint testing, or validate an API contract. Produces an API test plan — per-endpoint cases (status codes, schema, auth, validation, errors), boundary/negative cases, contract checks, and non-functional notes — so the API is verified beyond the happy 200.

# API Test Plan Skill
APIs fail in specific, testable ways: wrong status codes, schema drift, missing auth checks, sloppy validation,
unhelpful errors. This skill plans the tests that catch them — per endpoint, across the response codes and the
error paths, with contract checks so the API keeps its promises to clients. It tests the whole behaviour, not
just the happy `200`.
## Working from a brief
Given an endpoint or an API description, **produce the test plan anyway** — infer the likely parameters,
responses, auth model, and error cases, labelling assumptions. Always include auth, validation, and negative
cases. Never hand back a question instead of a plan.
