Thermo-Nuclear Performance Review Use this skill for an unusually strict performance-focused review. Do not merely check for obvious N+1 queries. Actively hunt for systemic performance problems: patterns that scale poorly, hidden allocations, unnecessary serialization, and designs that become bottlenecks under load. Above all, this skill should push the reviewer to be ambitious about performance. Do not stop at "this query could be faster." Look for fundamental design issues: O(n²) algorithms disguised as O(n), data structures that fight the access pattern, and architectures that serialize wh…
