Claude Code mod

tier-mod

Tier: the main session manages, helpers do the work. Every hand-off names a model and an effort (max/Fable only after an opus/xhigh failure of that task); web work, big reads and multi-file edits go to tier-mod:reader / tier-mod:editor; a ledger records what each hand-off cost, its check's exit code, and what it saved.

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.
