Generate comprehensive tests covering authentication, authorization, validation, happy paths, and not-found for an API endpoint or service. Use when a task asks to "add tests" or "write tests for <endpoint/service>", when a PR is missing test coverage, when starting from a spec with no existing code (TDD mode), or as the final step of feature-scaffold/bug-fix.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Write Tests

Generate tests for existing or new code so every endpoint is covered across
five required categories: authentication, authorization, validation, happy
path, and not-found. Concrete framework and runner command
(`{{TEST_FRAMEWORK}}`, `{{TEST_CMD}}`) live in `.agentry/project/stack.md`.

## Steps

1. **Read the implementation chain.** Route (identifier, HTTP method,
   middleware), Controller (methods, DI, response shape), Validator/Request
   (`authorize()` logic, rules), Service (business logic, edge cases),
   Model/Entity (relationships, scopes, casts, fillable), API Resource/DTO
   (response structure), Factory/Builder (available states).
2. **Determine test type and location.** API endpoint (controller +
   validator + resource) -> feature/integration test; service logic -> unit
   test; model scopes/methods -> unit test; background job/worker -> feature
   test. Exact layout is in `project/architecture.md`.
3. **Cover the five required categories for every endpoint** - non
   negotiable: authentication (401, unauthenticated rejected), authorization
   (403, wrong user/role/plan rejected), validation (422, one case per

How to install

The exact contents, by fingerprint

mdr add alexwaha/agentry/write-tests@sha256:4f95b6c5fdb9ec21

The line at the top of this page pins the label git:20261014.88e2c2f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
