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.

clawdling
21ersinkoc/claude-mods
KOZMOS Clawdling: a pixel crab companion that lives above the prompt. It blinks and sways, scuttles while tools run, thinks in bubbles, sweats past 80% context, dozes near the 5-hour limit and dances on a five-turn streak. It earns XP from tools and turns, levels up into a party hat, sunglasses, a scarf and a crown, and quips about what it sees. /clawdling toggles it, /clawdling feed treats it.
token-ledger
11Arunjay4213/claude-mods
