Claude Code mod

isobar

isobar, a Claude Code mod: a weather map for the session's change, drawn over a fixed map of the codebase, to read a complex change at a glance. A red storm sits on what Claude edited, each changed region is captioned with what the change did there, green rain falls on the code that uses what changed, the latest turn shows brightest, and an optional scope check flags edits nobody asked for.

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.
