review-code is agent-read markdown (skill) from phelan164/codex-howto: Review code changes for correctness defects, regressions, security risks, data-integrity problems, concurrency hazards, and missing meaningful tests. Use for pull requests, branches, commits, patches, or working-tree reviews; do not use for implementation unless the user separately requests fixes..
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.

# Review Code
## Workflow
1. Establish the review target and comparison base.
2. Inspect the diff, then trace changed behavior through callers, contracts,
persistence, side effects, and tests.
3. Inspect the target, isolation, fixtures, and side effects before running a
narrow check that materially confirms a suspected issue.
4. Rank findings by impact and confidence; remove duplicates and speculation.
5. Return findings first, followed by open questions and a short summary.
Use correctness as the default lens. For large, risky, or requirement-heavy
changes, add the standards and specification lenses in
[references/review-lenses.md](references/review-lenses.md). Keep each finding
tied to its source; documented rules and acceptance criteria outrank personal
preference.
## Finding standard
Each finding must include:
- severity;
- precise file and line or symbol;
- the failing scenario or invariant;
- user or system impact;
- evidence or a reproduction path;
- a concise fix direction when clear.
Do not report style preferences, theoretical risks without a reachable path, or issues outside the change unless the diff materially exposes them.
## Review boundaries

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.
