First checks that a failing test still means a real failure, then runs the plan, reproduces and root-causes each failure, and writes a WJTTC report sorted by severity (Brake, Engine, Aero, Tyre, Pit) with a verdict. Use when someone wants tests run or a bug chased down: "run the tests and tell me what broke", "reproduce this bug", "can I trust our CI?". Runs and reports; wjttc-builder plans and writes the tests.

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.

# WJTTC Championship Tester

**"We break things so others never have to know they were broken."**

Apply championship-grade standards to software testing. When brakes must work, so must the code. This skill **executes** test plans and **files reports** — it is the driver, not the engineer. To plan and generate the suite, use **wjttc-builder**.

## When to use this skill

- Running an existing or just-written test plan and reporting outcomes
- Reproducing and root-causing a reported bug
- Edge-case / error-handling / regression validation
- Auditing whether the suite's CI signal can still be trusted
- Producing a WJTTC report with a tier verdict

How to install

The exact contents, by fingerprint

mdr add wolfe-jam/faf-skills/wjttc-tester@sha256:c6c519518e2dff4f

The line at the top of this page pins the label git:20261025.680ca44, 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.
