Claude Code mod
project-sentinel
Project Sentinel keeps long Claude Code runs on track: a status bar, the Control Room panel, Context Autopilot (automatic handoff to a fresh context), Cache Guardian (the prompt cache in view, kept warm on request), Operations (work queued for later, decisions Claude leaves for you, watchers that wake a parked run, a Cold Resume Guard), permission categories that ask or deny, a run chain, Frontier Max, a lazy-exit guard, a model router, subagent limits, Focus view, machine load and Kit, an optional pixel companion.

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.
