frontend-verify is agent-read markdown (skill) from jeong-sik/masc: Verify an implemented web UI change in Firefox or Zen using Browser Lane evidence. Use for before/after comparison, responsive or state regressions, and checking that a frontend change actually works..

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

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.
