complexity-reduction skillA

complexity-reduction is agent-read markdown (skill) from rustyrazorblade/skills: Measure cognitive complexity and duplicate code with PMD (Java) or rust-code-analysis-cli (Rust), then reduce both by pure-move extraction, re-measuring after every step. Runs over a subsystem or over a PR diff. Use this when the user asks to simplify, refactor, clean up, or reduce the complexity of a subsystem, asks "how complex is X", asks to find duplicate code, asks to make code "beautiful", or asks for a complexity check on a diff or PR. It measures before it edits and re-measures after; it.

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.
