code-reviewer is agent-read markdown (skill) from cowork-os/cowork-os: Perform professional code review for local changes or GitHub pull requests..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# code-reviewer
## Purpose
Perform professional code review for local changes or GitHub pull requests.
## Routing
- Use when: Use for formal, structured review workflows on local diffs or GitHub PRs.
- Do not use when: Don't use for one-off formatting checks without code-quality feedback.
- Outputs: Findings grouped by severity with rationale and approval/revise recommendation.
- Success criteria: Covers correctness, maintainability, performance, security, and testability.
## Trigger Examples
### Positive
- Use the code-reviewer skill for this request.
- Help me with code-reviewer.
- Use for formal, structured review workflows on local diffs or GitHub PRs.
- code-reviewer: provide an actionable result.
### Negative
- Don't use for one-off formatting checks without code-quality feedback.
- Do not use code-reviewer for unrelated requests.
- This request is outside code-reviewer scope.
- This is conceptual discussion only; no tool workflow is needed.
## Runtime Prompt
- Current runtime prompt length: 3052 characters.
- Runtime prompt is defined directly in `../code-reviewer.json`.
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
