Settings → System → Diagnostics runs codeman doctor on the server (GET /api/doctor) and lists which agent CLIs, tmux, Node and the optional office tools are installed, their versions, paths and install hints. The probe runs in a child process so a slow --version can never freeze the server; admin only in multi-user mode.
