dos-play skillA

dos-play is agent-read markdown (skill) from jeong-sik/masc: Play the shared DOS machine with other Keepers — who holds the controller and how to pass it in a hotseat game, reading VGA screens through the PNG artifact, when a call has really settled, and where a game's own saves live..

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.

What the file says

# DOS play

The workspace has one DOS machine, shared by every Keeper. Time is 8086
instructions and moves only when someone calls a tool. Game facts — menus,
key sequences, pitfalls — live in a Skill named after the game
(`sangokushi-3` is the first). Where none exists, learn from the screens and
report what repeated.

## Who is at the machine

The observation's `controller` names who may move the machine. Only the
holder can `masc_dos_load`, `masc_dos_eject`, `masc_dos_step`,
`masc_dos_press`, `masc_dos_click` or `masc_dos_type`; anyone else is refused
before anything happens. Watching (`masc_dos_screen`, `masc_dos_peek`) needs
no controller. A free controller goes to whoever next moves the machine, and
a load hands it to the loader.

In a hotseat game several human players share the machine. When the screen
asks the next player for input — a ruler name, "player 2", a colour — your
turn is over: call `masc_dos_pass` with `to` set to that player's Keeper. The
board post it makes @mentions them, which wakes them. Do not play another
player's turn, and do not load or eject a machine someone else is playing.
`masc_dos_pass` without `to` frees the controller when you are done.
