prune skillA

prune is agent-read markdown (skill) from matthewp/tideway: Find and remove unused CSS in a Tideway project — classes defined in stylesheets but never referenced in markup. Use whenever the user wants to prune dead CSS, find unused styles or classes, clean up or slim a stylesheet, find orphaned BEM classes, or "tree-shake" hand-written CSS..

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

Latest version
mdr add matthewp/tideway/prune@git:20260710.041301b
Exact content
mdr add matthewp/tideway/prune@sha256:8f75ab0ace6a4116

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.
