Applies a consistent, language-agnostic review framework to any code change. It evaluates code across five dimensions, produces prioritised findings with inline suggestions, and distinguishes blockers (must fix before merge) from improvements (worth addressing but not blocking).
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 this skill does
Applies a consistent, language-agnostic review framework to any code change. It evaluates code across five dimensions, produces prioritised findings with inline suggestions, and distinguishes blockers (must fix before merge) from improvements (worth addressing but not blocking).
## When to use it
- User asks to "review this code", "review this PR", or "give feedback on this diff".
- User pastes a code snippet and wants quality feedback.
- User wants a second opinion before raising a PR.
- User needs a review checklist for a team standard.
## Review dimensions
| Dimension | What to check |
| --- | --- |
| **Correctness** | Logic errors, off-by-one, null/undefined handling, edge cases not covered |
| **Security** | Input validation, injection risks, secrets in code, insecure defaults, least-privilege violations |
| **Maintainability** | Naming clarity, function/class size, duplication, coupling, missing or misleading comments |
| **Performance** | N+1 queries, unnecessary allocations, blocking calls, inefficient algorithms for the scale |

The line at the top of this page pins the label v1.0.0, 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.
