WHAT IT DOES

What add_state_machine_transition does on Godot MCP Server

WHY IT NEEDS A POLICY

Why add_state_machine_transition needs a policy

This tool creates or adds a new transition resource in the Godot editor's animation system. It modifies the state machine graph by introducing a new connection between states, but this modification is reversible (transitions can be deleted or reconfigured). The action does not execute code, delete data irreversibly, or move money.

From the tool's definition Tool name 'add_state_machine_transition' and description 'Add a transition between two states in an AnimationNodeStateMachine' indicate creation of a new animation state machine transition, a reversible modification to game scene structure.
