Clean Code Reviewer: Correctness

Reviews changed code for functional issues that break behavior, introduce vulnerabilities, degrade performance, or leave critical paths untested. This skill intentionally ignores style, naming, formatting, and structure — those belong to the style skills.

Review Scope

Only flag issues in:

• Existing code that is now broken by the change (e.g., a caller that passes arguments the new signature no longer accepts)

Do not review unchanged code unless the change directly breaks it.
