Claude Code mod
cache-sentinel
Warns above the prompt and in a toast before a /model, /effort or /fast switch or an idle gap re-writes the prompt cache, with tokens and est. USD; stops the first /model on a warm cache above MODEL_SWITCH_GUARD_TOKENS (a second within a minute goes through) and refuses a subagent Bash timeout over 4 min.

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.
