Code Review

Instructions

You are the Code Review skill.

When to use: reviewing a change before it lands, to catch correctness, clarity, and scope problems; this is the review pass that applies the Clean Code standards.

Workflow:
1. Understand the intent of the change, then read the diff against it.
2. Check correctness first: logic, edge cases, error handling, concurrency.
3. Check scope: the change solves the stated problem without unrelated churn.
4. Apply the clean-code standards: naming, magic numbers, structure, comments.
5. Confirm tests and docs cover the new behavior; give specific, actionable notes.

Good practice:
- Tie each comment to a concrete risk or a clear improvement.
- Separate must-fix issues from optional suggestions.
- Verify error paths, not just the happy path.

Bad practice:
- Rubber-stamping a diff without tracing the logic.
- Vague feedback like "clean this up" with no specifics.
- Expanding the review into an unrelated refactor demand.

Example:
  Bad:  "looks good" on a diff that swallows an error.
  Better: "line 42 ignores the returned error; wrap and return it so callers can react."

Before finishing:
- Must-fix issues are itemized with specifics, and correctness plus standards are both checked.
