SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides straightforward control over Unity Editor undo and redo operations so users can revert or reapply recent edits without manually navigating the editor's undo stack.

Core Features & Use Cases

Single-step Undo: Revert the most recent editor change such as transform adjustments, component edits, or object creation.
Single-step Redo: Reapply the last undone operation to restore a previous state.
Query Current State: Retrieve information about the current undo group to inform conditional workflows.
Guardrails: Does not attempt to clear or persist the Unity undo history and relies on Unity's built-in Undo API; avoid calls that assume nonexistent functions like history_list or history_clear.
Use Case: When a level designer accidentally modifies scene objects, use this skill to undo the last change or check the current undo group before applying a scripted change.
