Use when writing tests or verifying behavior before code lands — the stage that writes the plan's tests and runs them RED before build; TDD red-green-refactor, the iron law (no production code without a failing test first), seam-first public-interface tests, test sizes, mock discipline. Or when the user says "TDD N loops each batch Opus loop", "batch properly, Opus on each batch before commit", "implement, use TDD", or wants multi-feature TDD with per-batch Opus review before commit.

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 Evals ## Overview The test-and-evaluation stage of the dev-pipeline: how behavior is pinned before it ships. Test-driven development is the core discipline; the batched multi-feature TDD loop with a per-batch Opus review, the pre-commit verification pipeline, and external-review-finding verification hang off it. **Core principle:** If you didn't watch the test fail, you don't know if it tests the right thing. **Tests verify behavior through public interfaces.** A bad test is one that breaks on a refactor without a behavior change. ## This stage owns the tests In the pipeline, the plan names each task's test cases (behavior, seam, expected value and where it comes from). This stage turns them into real tests, runs each one to a failure for the right reason, and attests the files (`review-commit/scripts/attest_file.py attest`) so the build can't quietly rewrite them. The `build` implementer makes them GREEN; it adds a test only for behavior the plan missed, and says so. Output of this stage: the test files, a RED run log, and one line per test naming the seam note it pins. ## When to Use …

How to install
mdr add moonlight-lupin/agent-skills/test-evals@sha256:ee374596a800c309The line at the top of this page pins the label v2.0.0, 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.
