cf-optimize skillB

cf-optimize is agent-read markdown (skill) from dinhanhthi/coding-friend: Structured performance work — baseline, analyze, optimize, measure, compare. TRIGGER — "this is slow", "make it faster", "optimize", "performance", "bottleneck", "too many queries", "high latency", "memory leak", "speed up", "timeout", "N+1", or any request to reduce time, memory, or query count with numbers to prove it. SKIP — minor refactors, readability or style changes, and correctness bugs that are not performance-related (use cf-fix)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
