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.

blocks-only
h3h/blocks-only
Coding turns end in a validated report of typed blocks, drawn as one card in the Desktop app; prose stays folded.
warden
21ersinkoc/claude-mods
KOZMOS Warden: a guard for destructive shell commands. Before Claude or a subagent runs rm -rf on a broad path, git push --force, reset --hard, clean -fd, DROP TABLE, mkfs, format, curl | sh and their kin, warden asks you (Allow once / Deny) and refuses when no one can answer. A band flashes for 8 s after a block; /warden lists the rules and this session's log.
rubber-duck

A fast second opinion on every edit: a small model flags removed error handling, deleted tests, secrets and more
file-guard
4Singh-AP/awesome-claude-mods

muster
2musingfox/cc-plugins
[Experimental] Unattended Claude workers over ACP — a coordinator dispatches headless workers with an optional permission fence, an event log, file-based escalation and report-file completion; a Claude Mod band shows in-flight workers (needs Claude Code 2.1.304+)
