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.

Workflow mods/plugin install

clef-verify

williamchen0606/claude-mods

Before Claude ends a turn that changed files, has Cloudflare's Clairic extraction model read the command output and the Clef decision model check that the work is shown to be done (tests run and passing where needed, claims backed by the steps, nothing asked for left undone), and sends Claude back if not.

threesil/claude-mods

Claw mod: wakes Claw up on a schedule inside a running Claude Code session. Daily briefing at a set time, periodic checks for overdue tasks, quiet hours, and an optional auto-run mode that makes Claude do the heartbeat by itself.
