ponytail-sec skillA

ponytail-sec is agent-read markdown (skill) from andypitcher/ponytail-sec: Security companion for active development. Scopes to the current diff or changed files. Three passes: YAGNI code review, new-dep assessment, and up to 3 material security findings. Lean by design — surfaces the one thing to fix before merging, not a backlog. Use ponytail-sec-audit for a full project scan..

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 andypitcher/ponytail-sec/ponytail-sec@git:20260915.1335b79
Exact content
mdr add andypitcher/ponytail-sec/ponytail-sec@sha256:463b66940cffedb7

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.
