About this mod
Anthropic's Boris Cherny tweeted announcing that Claude Mods is starting to roll out, and mentioned that someone in the community has already made a mod to "play Tetris inside Claude," which surprised him. The tweet includes a demo video and a link to a GitHub issue (a comment on anthropics/claude-code#91870). That issue aggregates the latest community progress, technical details, and more demos. Beyond the post body, the supplementary content is a prompt template: it asks for Claude Code desktop to hide sensitive values by default and only show them on hover, and notes that Mods is still in early access and the API may change. This entry is news/resource type, not a showcase of a specific mod.
