How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

mize-coworker
1TheMizeGuy/clawdagotchi
Claude as a small coworker in the terminal: an orange pixel-art Claude, two rows tall, in 132 frames. While a turn runs he sits beside the spinner in a scene for every spinner word (a thought bubble, a pen on a notepad, a book, a magnifying glass over text or over a globe, a laptop, a terminal, his own small helpers, a gear, a scroll for a skill, a plug for an MCP call); idle on the status row he breathes, blinks, strolls, yawns and sips a coffee, sweats near a full context and sleeps frosted once the prompt cache goes cold. While the main session rests and agents or workflows work in the background he minds them with a skit every few seconds: a rocket as they start, a paddle with how many are at work, a radar, a headset, a helper bringing a finished agent's report, juggling, bubble gum, popcorn, a paper plane, a plant that grows with the wait. The spinner word says what is happening (Reading register.ts, Running npm), and /coworker demo plays every animation once. Draws only; nothing reaches the model.
