code-review is agent-read markdown (skill) from firzus/agent-skills: Review a scoped diff against requirements, project standards, and correctness using independent read-only reviewers. Use for branch, PR, or uncommitted-change review, and implementation review checkpoints..
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
# Review a change independently
Return verified findings, not edits. Keep requirements, standards, and correctness
separate: a passing axis cannot hide a failing one. The caller owns corrections,
tests, and delivery. Review does not authorize publication or product execution.
## 1. Fix the review scope
1. Read the request and project instructions. Identify repository, authoritative
issue/spec, delivery boundary, and task-owned changes. Prefer supplied requirements,
then verified links in the work record or commits; never infer intent from code.
2. Resolve the base to a commit ID and state the comparison:
| Request | Comparison |
| --- | --- |
| Explicit range | Requested endpoint or merge-base comparison, stated explicitly |
| PR / branch against target | Verified target and merge-base with reviewed head |
| In-progress implementation | Recorded task baseline plus scoped committed, staged, unstaged, and untracked changes |
| Ambiguous base / ownership | Ask before review; never silently assume `main` or include unrelated work |
3. Validate refs and inventory additions, deletions, renames, and relevant untracked
…
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.
