Every Apply button writes a row into a per-project command queue with a type and a JSON payload. Nothing is executed by the website itself — the plugin is the only thing that touches your place.
The plugin authenticates with your project's connection token, then POSTs to /api/public/plugin/poll every 1.5 seconds. Pending commands are claimed atomically, executed inside a ChangeHistoryService recording (so Ctrl+Z works), and the result is reported to /api/public/plugin/result.
create_script, update_script, read_script, build_instances, set_properties, delete_instance, terrain_fill, clear_terrain and get_tree.
On connect — and whenever you press Sync place — the plugin serialises up to 1,500 nodes of your hierarchy and uploads it. That snapshot is fed to the AI as context so it reasons about the systems you already have.
Paths look like ServerScriptService/Systems/Combat. The first segment is a service; missing intermediate folders are created automatically.
The connection token is the plugin's only credential — treat it like a password. Rotating it is as simple as creating a new project. Commands are scoped to the single project that owns the token.
