Launches read-only subagents in parallel for three fixed adversarial missions (quality, security, six-month premortem) and a fourth chosen for the change (architecture, devil's advocate, or another kind the change calls for). They work on top of the deterministic checks the project runs (mutation testing, linters, audits). Then one verifier that did not produce the serious findings reproduces them, and the review ends with a verdict and what it did not cover. Findings count by evidence, such…

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

# Red team review

## Target and oracle

Settle both before the missions start, in two lines the user can correct:

- **Target:** the document path, or the branch, the base and the exact commit hash. The review covers that hash only. Commits added later are not reviewed, and the report says so.
- **Oracle:** what the change must keep or reach. For a refactor or any change that promises "no behavior change", the oracle is the base branch: the same input must give the same responses, rows, events and messages. For a feature, it is the spec and its acceptance criteria. For a spec or a plan, it is the request and the code it will touch.

## Facts first

Some checks are deterministic: a tool gives the same answer every time and costs no agent turns. Examples are mutation testing (the proof that the tests kill a broken line), the test suite run on the base, linters and static analysis, dependency audits, secret scans, architecture tests, a diff of routes or commands, a merge of the other active branches with the test suite. They are facts, not missions.

How to install

The exact contents, by fingerprint
mdr add webreactiva/yesyak/red-team-review@sha256:bc187cb4589f0522

The 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.
