codyssey is a free, open-source Claude Code plugin that turns each coding session into a small adventure. miod writes music on the spot that follows what the agent is doing. knightod sends a pixel knight to fight a monster for every edit and command, with levels, bosses, gold and weapons. scrollod retells the transcript as a game-style quest log. Each mod turns on and off on its own. No music files, no AI model, all in your terminal. Music plays on macOS.
