Built-in skill — code review.
Injects a system-prompt section covering five review passes — bug detection, style and readability, performance (N+1 queries, allocations, missing indexes), security, and best practices — and requires every finding to carry a location, a severity (critical / warning / suggestion) and a concrete fix.
Activates on prompts containing "review", "code review", "check this code" or
"review my". Group :review; tags :code, :quality, :review.
