Have the agents behind rival answers to one question check each other's answers, then pick on the evidence. Use when independent answers to one question disagree, or would, and no test, file or run can settle which is right.
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
The authors answer blind. No answers yet → ask two or three subagents, each on a different model, the same question with the same files. Write down the pick you would make from the answers alone. Send each author the other answers, never its own, by message to the same agent. Ask: - per rival: what it gets right that yours misses, and what breaks if it is wrong, each with a file:line, quote or number - whether the rivals change your pick, and why A critique with no evidence goes back to its author once. Pick on evidence, never on how many authors back an option. Hand back: - the pick, in one sentence - per option: the fact that decides it, where it lives, who raised it - the strongest objection to the pick, who raised it, and whether it held - what the critique changed from the pick you wrote down - what stays open The answers agree, or one check settles the question → settle it yourself.

How to install
mdr add saadshahd/moo.md/cross-check@sha256:0f99f32fd34d7ef0The line at the top of this page pins the label git:20261021.d06a656, 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.
