cf-optimize skillB
cf-optimize is agent-read markdown (skill) from dinhanhthi/coding-friend: Structured optimization — baseline, analyze, optimize, measure, compare. Auto-invoke for performance/speed — e.g. "this is slow", "make it faster", "optimize", "performance", "bottleneck", "too many queries", "high latency", "memory leak", "speed up", "timeout", "N+1". Do NOT auto-invoke for minor refactors or style changes that are not performance-related..
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.
How to install
mdr add dinhanhthi/coding-friend/cf-optimize@git:20260827.debd979mdr add dinhanhthi/coding-friend/cf-optimize@sha256:30f8d44cbbe0dfd9Pin 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.
