Claude Code mod

agent-ctx

Each agent loop's own context fill, measured per request; a one-line CONTEXT_PCT_ALERT rides that agent's next tool result. Subagents: absolute 200k warn / 250k finish / 300k stop (stop line on every result); main: 70/75/80% of its window. Controllers get CHILD_CTX on Agent and SendMessage results and CHILD_CTX_ALERT when a live child passes 250k/300k

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.
