Gulltopp's guide
Scripts place, you decide
A script places pieces from the library. You can write it, or a language model can through the command line or MCP server. A loop lays a run of wall, scatter plants a wood, and one line places a gate or a tower.
Everything a script makes is an ordinary object in the scene. Pick a gate that stands wrong and move it, turn it or delete it like any model. A whole script run is one Undo step.
