Verifies an implementation against its spec criterion by criterion. It maps every acceptance criterion to tests and code, fills coverage gaps with reproduction scripts, lists deviations that are not criteria, and writes a verification report. Use it whenever the user asks to check the implementation against the spec, which criteria are met or not, whether the work is complete, or for a coverage or compliance report before review or merge.
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
# Verify against spec Passing tests are not the goal. The question is "is every promise in the spec kept, and how do we know". ## 1. Collect evidence 1. Run the full check and record the result. 2. List every test name with a verbose reporter, for example `npx vitest run --reporter=verbose` or `pytest -v`. 3. For each acceptance criterion, find the tests that cover it and the code that implements it. ## 2. Classify each criterion | Level | Meaning | | --- | --- | | Suite, full | A test in the suite covers every part of the criterion | | Suite, partial | Tests cover part of it; you checked the rest with a script now | | Logic tested, entry point manual | The logic has tests; you checked the command or script around it by hand | | Manual only | The spec says it is manual, or no automated check is possible | | ❌ Not met | The behavior differs from the criterion | Be strict. A test that checks the ids in a list does not cover "shows id, customer, total and state". ## 3. Check the gaps with a script …

How to install
mdr add webreactiva/yesyak/verify-against-spec@sha256:852cbbedbeb3fa69The line at the top of this page pins the label git:20261017.b634987, 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.
