Claude Code mod
session-guardian
Keeps long sessions cheap and easy to pick up: warns before a session's cache goes cold and what coming back costs, nudges a wrap-up past a set size, saves a quiet session's state by itself before its cache goes cold, holds a command that keeps failing, and adds /wrapup, which also saves the session's dead ends.
Install
/plugin marketplace add A-rdit/session-guardian

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.
