Claude Code mod

cache-guard

Keeps the prompt cache warm while you are away, asks before a prompt that would re-cache a large conversation, and with Jev (TypeSafe) keeps the context lean: trims large tool output and compacts in about a second.

Install

From source
git clone https://github.com/justmytwospence/claude-cache-guard.git
claude --plugin-dir ./claude-cache-guard/.

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.
