Before committing substantial work, at worker completion, before external review, or on an explicit adversarial/red-team request for a diff, branch, or PR, use independent finders and a skeptic to verify defects, disposition findings, and enforce the blocker gate.
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
# Adversarial review
Read the [Codex desktop binding](../../../CODEX.md) when this workflow needs harness mechanics, model routing, or recovery.
Reviewers whose job is to find what is **wrong** with a change before it ships, not to summarize it, not to appreciate it. This skill is the portable protocol: isolated finders, a skeptic pass that separates proven defects from plausible ones, and a gate that only skeptic-confirmed blockers may hold. Everything a repo does differently (its defect history, its probe policy, its stakes) lives in **binding slots** the team-workflow setup interview fills.
Read the team-workflow binding doc first. The review runs **before external reviewers** (CodeRabbit, Copilot, human PR review) see the change: they are the safety net, not the review.
## 1. The two layers
1. **The floor: before committing substantial work.** The implementing session reviews its own change before the commit. Every repo bound to the pack has this layer.

The line at the top of this page pins the label git:20261008.0b04f1c, 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.
