Reviews a change — a diff, a PR, a branch, or uncommitted work — for correctness, risk, and maintainability, and reports findings ranked by severity. Use this whenever the user asks you to review, check over, or give feedback on code they or someone else wrote, mentions a pull request, or says a change is "ready", even if they only ask "does this look ok?". For examining a whole codebase rather than a change, use code-analysis; for vulnerabilities specifically, use security-analysis.
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
A review is a search for the ways this change fails in production, ranked by how badly. It is
not a style pass. Style is the lint job's work — if you spend the review on formatting, you
have used up the reader's attention on the cheapest possible findings.
The bar for reporting: **could you write the input that makes this go wrong?** If not, you have
a question, not a finding. Say it as a question.
## 1. Understand the intent before reading the diff
Read the PR description, linked issue, or ask. Reviewing a change without knowing its goal
produces suggestions that fight the author's purpose.
Then decide what *should* have changed. Files you expected to see and don't are the highest-
yield finding in any review — a new state field with no migration, a new branch with no test,
a new error path with no logging.
**Done when:** you can state the intent in a sentence, and you have a list of what you expect
the diff to touch.
## 2. Read the change in dependency order
Not top to bottom, and not alphabetically, the order the tool shows you is meaningless. Start
at the data model or interface, then the logic, then the callers, then the tests. Meaning flows
…
The line at the top of this page pins the label git:20260828.866dec6, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
