History Skills

Manage Unity Editor undo/redo history.

Operating Mode

本模块 history_get_current（纯读）标 SkillMode.SemiAuto，三档下均可直接执行；history_undo / history_redo 会改变场景状态，为默认 SkillMode.FullAuto（Operation=Execute），Approval 模式下需 grant。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

Skills

`history_undo`

Undo the last operation.

Parameters:

steps (int, optional, default 1): Number of operations to undo.

`history_redo`

Redo the last undone operation.

Parameters:

steps (int, optional, default 1): Number of operations to redo.
