Tool categories:
- Project management: launch_editor, run_project, attach_project, detach_project, stop_project, get_debug_output, list_projects, get_project_info
- Scene editing (headless): create_scene, add_node, load_sprite, save_scene, export_mesh_library, batch_scene_operations
- Node editing (headless): delete_nodes, set_node_properties, get_node_properties, attach_script, get_scene_tree, duplicate_node, get_node_signals, connect_signal, disconnect_signal
- Runtime (requires run_project or attach_project): take_screenshot, simulate_input, get_ui_elements, run_script
- Project config (no Godot process): list_autoloads, add_autoload, remove_autoload, update_autoload, get_project_files, search_project, get_scene_dependencies, get_project_settings
- Validation: validate

Key behaviors:
- All mutation operations (add_node, set_node_properties, delete_nodes, etc.) save the scene automatically. Only use save_scene for save-as (newPath) or re-canonicalization.
- Headless Godot initializes ALL registered autoloads. If any autoload is broken, headless operations will fail. Use list_autoloads / remove_autoload to diagnose.
- run_project verifies bridge readiness before returning success. If it reports degraded status, retry runtime tools after a moment or check get_debug_output.
- attach_project is the fallback path for a manually launched Godot process. It injects the bridge and marks the project active, but it does not spawn Godot or capture stdout/stderr.
- click_element in simulate_input resolves by node path or node name (BFS search), NOT by visible text. Use get_ui_elements to discover valid element identifiers.
- run_script expects GDScript with "extends RefCounted" and "func execute(scene_tree: SceneTree) -> Variant".
- run_project spawns Godot without -d so runtime errors do not pause execution; the \`breakpoint\` keyword in user code is a no-op (no debugger is attached). SCRIPT ERROR output and GDScript backtraces still appear in stderr.`;
