Conducts and responds to code review — reviewing a change for correctness, design, and risk, and evaluating review feedback received on your own work. Use this before merging, when asked to review a diff or pull request, when review feedback has arrived and needs acting on, or when feedback seems wrong and needs a reasoned response rather than compliance.
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
# Code review
Two directions, one skill: reviewing, and being reviewed.
## Reviewing
Read the diff against what the change is *for*, not against your preferences. Order matters — spend
attention where damage is expensive:
1. **Correctness** — does it do what it claims, including at the boundaries and on the error path?
2. **Blast radius** — what else consumes this? Signature and schema changes are the ones that break
things far away.
3. **Security and data** — untrusted input, authorization, anything logged or persisted.
4. **Tests** — do they pin the new behavior, or do they pass regardless?
5. **Design** — will this shape hold under the next change?
6. **Style** — last, and only where a linter cannot.
Say which category each comment is, and whether it blocks. A review that mixes a data-loss bug with
a naming preference in one undifferentiated list wastes the author's judgment.
## Receiving
Feedback is a report of a reader's experience, and that part is always valid — if the reviewer
misread it, the code is misleading. The proposed remedy is a separate thing and may be wrong.

The line at the top of this page pins the label git:20260828.f80dcb5, 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.
