History Skills

DO NOT (common hallucinations):
history_list / history_get do not exist → use history_get_current for current undo grouphistory_clear does not exist → Unity undo history cannot be cleared via APIhistory_save does not exist → undo history is managed by Unity automatically
Routing:
- For simple undo/redo →
history_undo / history_redo (this module) or editor_undo / editor_redo
- For persistent task-level undo → use
workflow module
- For conversation-level undo → use
