- description: Perform a structured code review on a diff, PR, or staged changes — surface correctness, security, error-handling, architecture, testing, and clarity issues with file/line references and severity. Use this skill when the user asks to review code, audit a diff or PR, find bugs in changes before merging, sanity-check work before pushing, or look over an implementation — including when phrased softly ("look over this", "check if this is OK", "глянь, всё ли нормально", "посмотри на это").

# Code Review
Systematically review changes for correctness, security, and maintainability.
## Steps
1. Read the full diff. Understand the scope before commenting.
2. Check PR description or commit messages for context — what problem is being solved?
3. Review in priority order:
- **Correctness** — Logic errors, off-by-one bugs, missing edge cases, race conditions.
- **Security** — Injection risks, hardcoded secrets, missing validation, exposed PII.
- **Error handling** — Unhandled failures, swallowed exceptions, missing error paths.
- **Architecture** — Does this follow existing patterns? Are boundaries respected?
- **Testing** — Are new behaviors tested? Are error paths covered?
- **Naming & clarity** — Would a new team member understand this?
4. For each issue:
- Point to the exact file and line.
- Explain *why* it's a problem, not just *what* to change.
- Suggest a fix when possible.
- Mark as **blocking** (must fix) or **suggestion** (nice to have).
5. If the code is solid, say so. Don't manufacture criticism.
## Output Format
```
## Summary
[1-2 sentence overview]
## Issues
- **[blocking]** file.ts:42 — [problem and suggested fix]
- **[suggestion]** file.ts:15 — [observation and reasoning]
## Verdict
[Approve / Request changes / Needs discussion]
```
## Gotchas
- Don't nitpick style if a formatter/linter handles it.
- Don't rewrite the author's approach — review what's there, not what you'd have written.
- Don't approve with unresolved blocking issues just to be polite.
- Check the full PR, not just the latest commit — bugs often hide in earlier commits.
