Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.
Identify the API stack:
openapi.yaml, swagger.json, .proto files, GraphQL schemaIf no API test tool is configured, recommend based on the stack (Supertest for Node, pytest+httpx for Python, etc.).
Build a complete endpoint inventory:
| Method | Path | Auth | Request Body | Response | Tested? |
|---|---|---|---|---|---|
| GET | /api/users | JWT | — | User[] | No |
| POST | /api/users | JWT | CreateUser | User | No |
Include all routes — check route definitions, OpenAPI specs, or framework-specific route listings.
For each endpoint, test:
If there are service-to-service calls or a public API:
For performance-critical endpoints:
Summarize what was built or configured in the CLI skeleton format with key findings and next steps.
test123 for every fieldIf output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
npx claudepluginhub tonone-ai/tonone --plugin eval-regressBuild API test suites — endpoint testing, contract testing, load testing for REST/GraphQL/gRPC APIs. Use when asked to "test this API", "API tests", "endpoint testing", "contract tests", or "load test".
Automates testing of REST/GraphQL API endpoints from OpenAPI specs: generates requests, validates schemas/responses, covers auth, CRUD, errors, idempotency. Supports Supertest, pytest, REST-assured.
Contract testing, API mocking, integration testing, and end-to-end API testing.
