Fixture skill. Exists only so the eval harness has an artifact to bind its committed replay fixtures to, and so CI grades a real prompt set instead of only asserting that an empty fixture set fails. Triggered by the four cases in evals/prompts.json and by nothing else. NOT FOR any real task: it does nothing, and no agent should ever load it outside tests/skill_evals/.
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
# harness-selftest This file is the artifact under test for `tests/skill_evals/fixtures/harness-selftest`. Every committed fixture in `../cases/` carries the SHA-256 of **this file** and of the `description:` above. Editing either one invalidates all of them — which is the point: it is the mutation CI performs on every PR to prove the gate can go RED. If you edited this file on purpose, regenerate the fixtures: ```bash python3 tests/skill_evals/fixtures/harness-selftest/generate.py ```

How to install
mdr add broomva/skills/harness-selftest@sha256:2ef627dbe77a4997The line at the top of this page pins the label git:20260728.dedf7e0, 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.
