ponytail-audit skillA
ponytail-audit is agent-read markdown (skill) from dietrichgebert/ponytail: Audit the whole repo for over-engineering. A ranked list of what to delete, simplify, or replace with stdlib or native features..
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 dietrichgebert/ponytail/ponytail-audit@git:20260619.bd6176amdr add dietrichgebert/ponytail/ponytail-audit@sha256:baba579ec3261cefPin 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.
