Claude Code mod
cachebeat
Keeps the prompt cache warm while a session sits idle: shortly before the cache would expire, a small background request re-reads it, without touching the transcript. A beating heart under the prompt shows it working, and Claude can read and change it for you. Each beat counts toward your usage.

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.

claudetto
3xsyetopz/dotclaude
Tunes Claude Code for coding at the lowest token cost, through its official extension points only: settings, hooks, skills, and an output style. It patches nothing. The tree is a rebuild in progress, and each capability lands with the measurement that decided its values. The one decided default is the compaction path, which stays the built-in compaction of Claude Code until a measured probe result beats it.
