Running EditorScripts?

[kotaweav]

Is there a way to run scripts in tool mode? I am having trouble running this example:

@tool
extends EditorScript

func _run():
	print("Hello from the Godot Editor!")

from https://docs.godotengine.org/en/stable/classes/class_editorscript.html

I get a No standalone script found. when I try to run gdscript-godot-run-current-script (which I assume is the equivalent of godot -s <script>). Note that I don't use Hydra.
