History Skills

Manage Unity Editor undo/redo history.

Operating Mode

本模块全部 3 个 skill (history_undo / history_redo / history_get_current) 均标 SkillMode.SemiAuto，Approval / Auto / Bypass 三档下都可直接执行。不含 NeverInSemi 高危 skill。

DO NOT (common hallucinations):

• history_list / history_get do not exist → use history_get_current for current undo group
• history_clear does not exist → Unity undo history cannot be cleared via API
• history_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 workflow module's workflow_session_undo
