Claude Code mod
context-band
Context-window squares by category above the prompt, with a prompt-cache countdown and an optional keep-warm refresh. Reads the context breakdown, the prompt draft's length and the session transcript's cache usage, all locally; a refresh (manual, or auto-refresh if enabled) sends one model request through Claude Code. Inside Herdr, it also flashes the session's entry in Herdr's agent list as the cache nears expiry, through the local herdr command.

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.
