Generates complete, ready-to-run API test scripts from any input — endpoint descriptions, Swagger/OpenAPI specs, Postman collections, curl commands, or plain English. Outputs working test code in the user's preferred framework: Python pytest + requests, Postman Collection (JSON), or JavaScript Jest + axios. Always trigger this skill for ANY of these situations: "API testing", "test this endpoint", "write API tests", "generate test cases", "Postman collection", "pytest for API", "REST API test", "API automation", "validate API response", "check my endpoint", "test my routes", "QA this API", sharing a Swagger/OpenAPI spec, sharing a curl command, sharing an API route or payload, or any request involving HTTP endpoint verification. Trigger even for vague inputs like "test this" when an API context is present — structured, runnable scripts are always better than ad-hoc manual testing.
