Plan and write the tests for a feature, bottom-up. Everything that code or the CLI can verify (pure logic, API endpoints, DB constraints, auth/role rules) is tested without a browser. UI end-to-end tests come last and cover only what the lower layers can't. Use when the user asks to plan tests, write tests, or add test coverage for a feature or checkpoint (e.g. "/ai-test-planner discount rules").

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

# Test planner

**If you're running as a subagent** (for example, launched by `/ai-orchestrator`), you can't launch subagents. Do the steps marked "subagent" yourself, and do only the steps and checkpoint cases you were asked for.

**Project specifics** (test file locations, commands, frameworks, how to act as a role, e2e sign-in) come from the **Project config** section of `AGENTS.md`. Read it first. If a value you need is missing there, infer it from the existing tests and config files, and say so in your report.

Keep plans and tests in the task's selected checkout, whether that is the current checkout or its chosen worktree.

Rule: **push every check to the lowest layer that can prove it.** A browser test is only for things that exist only in the browser. Layers run in order, and a layer runs only once the one below it passes:

| # | Layer | Proves | Where / Run |
|---|-------|--------|-------------|
| 1 | Unit | Pure logic: calculations, date math, state rules | Project config → *Unit tests* |
| 2 | API | Endpoints, role/permission checks, status codes, DB constraints surfacing as 409/422, state transitions | Project config → *API tests* |

How to install

The exact contents, by fingerprint
mdr add arcasilesgroup/ai-engineering/ai-test-planner@sha256:143f4f1f70141fec

The line at the top of this page pins the label git:20261106.9932b24, 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.
