Review code for correctness, security, performance, maintainability, and test quality. Use when the user asks for a review, audit, or change assessment.

Debug failures systematically by reproducing the issue, isolating the cause, applying a fix, and verifying the outcome. Use when the user reports a bug, crash, flaky behavior, or failing test.

Refactor code safely using small steps, tests, and proven patterns. Use when the user asks to clean up code, reduce duplication, or improve structure without changing behavior.
