what is launch-gui fr?

launch-gui solves a specific annoyance for people running AI coding agents in a terminal: those agent tools usually block normal shell backgrounding tricks like the trailing ampersand, nohup, disown, or setsid, so a command meant to open a graphical app in the background either gets rejected outright or hangs the whole session. This project documents and packages the fix for that problem, working with Hermes Agent, Claude Code, Codex, and OpenClaw. The fix itself is small: instead of trying to background a process through the shell, you use Python's subprocess.Popen with start_new_session set to true, called through whichever code execution tool your agent provides. This fully detaches the new process from the agent's own session, so a graphical app like a text editor or file browser opens on screen immediately while the agent gets its terminal prompt back right away, without waiting for that app to close. For Hermes Agent users, the project can be installed as a skill directly through Hermes's own skill installer, or by cloning the repository into the Hermes skills folder. For Claude Code, Codex, or OpenClaw, you simply copy the included SKILL.md file into your agent's instruction directory, or just remember the one line technique directly, since it does not require any special installation. A table of already tested applications is included, covering common Linux desktop tools such as Kate, Dolphin, Konsole, Firefox, VS Code, Okular, Gwenview, gedit, and Nautilus, though the technique works with any application that can be launched from a plain command line. The README also lists a few practical pitfalls: the DISPLAY environment variable must be set correctly for the app to appear, Wayland desktops need the WAYLAND_DISPLAY and XDG_RUNTIME_DIR variables set as well, connecting over SSH requires X forwarding or a local session, and if Firefox is already running, the command will simply open a new tab and then exit right away, which is expected behavior rather than a failure. The project is released under the MIT license.
