Check an artifact against a written spec one requirement at a time. Splits the spec into testable requirements, scores each met, partly met, not met or not applicable with a calibrated confidence, blocks on a confident not-met and sends the unsure rows to a person. Works on a PR description, an agent's answer, a generated test or an RFC. Use on "does this meet the spec", "did it do everything I asked", or a definition-of-done gate in CI.
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
# Check an artifact against a spec, one line at a time Asking a model "does this meet the spec?" gets a paragraph that is generous, unfalsifiable and different next time. Asking once per requirement gets a table you can block a merge on, in one call: each input is one requirement plus the artifact. ## When not to use it - When the spec is executable: a test suite beats this, so run the tests. - For behaviour the artifact does not describe. It reads the text in front of it, so a PR description that lies passes; point it at the diff too. - For requirements nobody wrote down. Write them down first. ## 1. Split the spec into requirements One testable claim a line, in the spec's own words: ``` The endpoint responds at GET /v1/health. The response body is JSON and includes the running version string. The endpoint checks the database before reporting healthy. An unhealthy dependency makes the endpoint answer 503. Responses are not cached by intermediaries. The endpoint is rate limited per IP. The mobile app shows a maintenance banner when health fails. ``` - **Split on "and".** "Returns JSON and is rate limited" scores as one blurred …

How to install
mdr add mrmps/classifier-dev/spec-conformance-check@sha256:36a2e1794b89a976The line at the top of this page pins the label git:20260919.33ae531, 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.
