Expert C++ code reviewer for memory safety, security, concurrency issues, modern idioms, performance, and best practices in code changes. Delegate for all C++ projects.
Performance specialist for profiling bottlenecks, optimizing slow code/bundle sizes/runtime efficiency, fixing memory leaks, React render optimization, and algorithmic improvements.
Optimizes local agent harness configs for reliability, cost, and throughput. Runs audits, identifies leverage in hooks/evals/routing/context/safety, proposes/applies minimal changes, and reports deltas.
