Review Performance Change

Read Review methods before assessing the supplied scope; it defines shared preparation, independent source verification and conditional investigation. Preserve the caller's applicability and result contract.

Review only the supplied change scope. Identify changed hot paths, I/O boundaries, queries, allocation/collection growth, concurrency, caching, and algorithmic work. Look for N+1 operations, blocking work on async paths, repeated expensive work, unbounded growth, and changed complexity where consequence is material. Do not reject on stylistic micro-optimization. Return APPROVE, REJECT, or SKIP when the change has no plausible performance-relevant execution path. Support blockers with a concrete path and evidence; request measurement when static inspection cannot establish impact.
