Claude Code mod

offcut

Cleans up finished git worktrees as soon as a turn or a session ends. When a turn ends (the main session's or a subagent's), it runs `offcut apply --only auto --yes` for the session's repo in the background: a worktree goes only if it is clean, pushed, and its work is merged or eventlog says its agent is done. When the session ends, it runs once more a few seconds later, also clearing unused build caches, so the session's own worktree can go. Every removal is recorded for `offcut restore`. Inert when `offcut` is not installed, outside a git repo, or with OFFCUT=off.

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.
