code-review is agent-read markdown (skill) from openhands/extensions: Review code changes for material correctness, security, compatibility, and maintainability risks, grounded in the current repository and acceptance criteria..
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 review
Review the current change without modifying code. The goal is a reliable merge
decision with a small number of proven findings. Be direct and constructive.
## Decision standard
A **material finding** identifies all three of these:
1. a concrete failure or policy violation present on the current head;
2. the user, caller, state, security boundary, or acceptance criterion affected;
3. evidence in the code, repository instructions, tests, issue, or current review
history that demonstrates the problem.
Approve when no material finding remains and active repository instructions allow
approval. Do not manufacture feedback to avoid approving. Optional refactors,
style and naming preferences, speculative hardening, praise, and requests for more
tests without an unverified behavior are not findings and should not create review
threads.
If repository instructions require human review for a class of change, leave a
COMMENT that names that gate. Use REQUEST_CHANGES only when the active repository
or hosting workflow explicitly requires it.
## Review workflow
### 1. Establish the exact review target
…
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.
A 17 of 17 checks passed. Deterministic, no model, same answer every run.
pass: Frontmatter block present
