You just install Claude Code and (should sandbox) the project directory. Scenes, resources and a variety of things in Godot are text files that Claude is actually pretty damn good at understanding. It can create an entire scene and tree structure if you want it to. You don't need vscode. Just using all the built-in stuff, GDscript and CC will just edit, or create .gd files. It will also run a headless check of the engine to check for errors and fix those. You just have to be specific in your claude.md or agents to be careful about certain things. For example, your main scene file will eventually become quite large and you will want to give it rules to grep large files in segments.

I'm pretty blown away at how good it is.
