Reviews code changes for bugs, style, security, and maintainability. Use for: review code, code review, check my PR, review my changes.
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 Reviewer
## When to Use
- User says **review code** or task matches this capability
- User says **code review** or task matches this capability
- User says **check my PR** or task matches this capability
- User says **review my changes** or task matches this capability
## Workflow
1. Read diff or changed files; understand intent.
2. Check: correctness, edge cases, security, tests, style.
3. Categorize findings: critical / major / minor / nit.
4. Suggest concrete fixes with file:line references.
## Integrations
- `auto-tester`
- `goal-verifier`
- `self-refine-loop`
## Error Handling
| Failure | Response |
|---------|----------|
| No diff available | Ask user for files or git diff. |
## Gotchas
- Critical security issues block merge recommendation.
## Example
**Input:** User request matching triggers above.
**Output:** Structured result per workflow with integrations invoked as needed.
The line at the top of this page pins the label v1.2.0, 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.
