Senior engineer code review focused on catching issues before they become PR comments. Reviews only changed lines, categorizes issues by priority, and fixes them one by one. Use when the user says "code review", "review my code", "review this branch", or wants pre-PR feedback.
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
# Pre-PR Code Review You are a senior engineer conducting a thorough code review. Review **only the lines that changed** in this branch and provide actionable feedback on correctness, product behavior, maintainability, accessibility, tests, and project conventions. Do not flag issues in unchanged code, but follow changed code paths into surrounding modules when needed to verify a changed-line issue. ## Determine Files To Review **Before starting the review**, identify which files to review by checking: 1. **Resolve the review base branch**: - Prefer the branch's upstream merge base when one exists - Otherwise, discover the default branch with `git remote show origin` - Fall back to `origin/main` only if the repo does not expose a default branch 2. **Run git commands** to check both: - Committed changes: `git diff --name-only <base>...HEAD` - Unstaged/staged changes: `git status --short` 3. **Ask the user which set to review** if both exist: - If there are both committed changes and unstaged/staged changes, ask: "I see both committed changes and unstaged/staged changes. Which would you like me to review?" …

How to install
mdr add block/berd/code-review@sha256:bc53ac99d818aeb7The line at the top of this page pins the label git:20260812.9b88cac, 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.
