# Review Code

> 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.

# 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

- Review in read-only mode by default.
- Do not run production-integrated, shared-environment, or destructive tests
  without explicit authorization and verified isolation.
- Do not modify, comment, approve, or request changes on a remote PR unless asked.
- Do not equate passing tests with correctness.
- Do not treat generated code or lockfile churn as a defect without understanding its source.
- Respect repository-specific compatibility and risk rules.
- State when a claim was not reproduced.

## Checklist

Read [references/review-checklist.md](references/review-checklist.md) when the change touches APIs, data, authorization, concurrency, infrastructure, or tests.

## Output

If there are no actionable findings, say so directly and name residual unverified areas. Keep the summary shorter than the findings.
