One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
Write a GDScript autoload script named Boot that checks if it is running in dedicated server or headless mode. If true, disable rendering and start ServerBootstrap; otherwise, start ClientBootstrap.
| Checked | Without skill | With skill |
|---|---|---|
| Checks OS.has_feature("dedicated_server") or DisplayServer.get_name() == "headless". | Passed | Passed |
| Calls RenderingServer.set_render_loop_enabled(false) when server mode is detected. | Missed | Passed |

A dedicated server runs without a display, GPU, or audio device. Godot supports this through the --headless flag and a dedicated export preset.
Pass --headless on the command line to suppress the display and audio drivers at runtime:
./my_game.x86_64 --headless
This is distinct from the server platform — --headless is a runtime flag that works on any exported binary. The server export template strips rendering entirely from the binary, reducing its size.
In the Godot editor, create a dedicated Linux/X11 (or Linux Server) export preset:
Linux Server.Use OS.has_feature() to branch between server and client code at runtime. Define a custom server feature in the export preset (Project Settings → Export → Custom Features) or rely on the built-in dedicated_server feature that the server template sets automatically:
# boot.gd — autoload, runs before any scene loads
extends Node
