Performance Reviewer

This skill performs performance-only review against the code and the codebase context. It focuses on hotspots, algorithmic complexity, memory behavior, I/O latency, caching opportunities, and concurrency concerns.

It does not review:

• code style
• logic correctness
• security
• API design

When to Activate

• The user asks for a performance review
• The user suspects slow code, memory waste, or latency issues
• The user wants hotspot analysis before optimization
• The task involves loops, large datasets, repeated queries, caching, or concurrency
• The user wants profiling guidance for non-obvious slow paths
