msx-observe skillA

msx-observe is agent-read markdown (skill) from jeong-sik/masc: Capture the current MSX screen and read that exact image, preserving its frame and artifact reference. Use when identifying a game prompt, date, menu, or visible change..

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.
