Field notes
Setup adds tools and a small background hook to Claude Code’s settings, and to Codex’s settings if installed; the page says `natter uninstall` removes them. Sessions still stop at permission prompts, though the security notes warn that a Codex session may remain open after its window closes and act on messages without someone watching. The listed requirements exclude Intel Macs and call for port 7777 to be open between machines.
