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.

Before a risky Bash command runs, says what it will touch. A plain deletion is judged by git: files outside git or tracked and clean get only a short label, a Ukrainian dialog (with the rm line, the number of files and a typed 'Other' decision) is for uncommitted changes, the home folder, more than 20 files and other hard risks. Static analysis plus read-only git, nothing is executed to preview.
