Glitchless Deck

glitchless-deck builds a game, checks it is something the Deck can run, sends it to the user's Steam Deck over the network and adds it to the Deck's library as "Devkit Game: ", playable in Gaming Mode. Only changed files travel, so repeat sends take seconds. It can start the game remotely, show what it printed, and measure it on the Deck with the Glitchless SDK, compared with a saved run.

Run it with npx -y glitchless-deck <command> (Node 20+), or glitchless-deck <command> if it is installed globally. glitchless-deck guide prints the full reference.

The MCP tools glitchless_deck_send and glitchless_deck_measure do the same as send and measure when the Glitchless MCP server is connected.
