Workflow Skills

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Undoing a whole task or session
• Snapshotting before risky changes
• Planning/previewing batch operations
• Rolling back
• 撤销整个任务或会话、高危改动前快照、规划/预览批量操作、回滚

Workflow Skills

Persistent history and rollback system for AI operations ("Time Machine"). Allows tagging tasks, snapshotting objects before modification, and undoing specific tasks even after Editor restarts.

NEW: Session-level undo - Group all changes from a conversation and undo them together.

Operating Mode

• Approval：本模块大部分 skill 标 SkillMode.SemiAuto（bookmark / history / task / session 系列里的纯读查询 + workflow_plan，后者 ReadOnly=true 仅生成聚合计划），可直接执行。有副作用的 skill (bookmark_set / bookmark_goto / workflow_snapshot_object / workflow_snapshot_created / batch_retry_failed) 走默认 SkillMode.FullAuto，需 grant。
• Auto / Bypass：FullAuto 直接执行。
• 含 NeverInSemi 高危 skill：bookmark_delete / workflow_delete_task（标 Operation.Delete，删除书签/任务记录）、workflow_clear_history（Operation.Delete + RiskLevel=high，清空全部历史+redo栈+文件存储，不可逆）。这些在 Approval/Auto 下返 MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

注意：workflow_undo_task / workflow_session_undo 不是 Delete operation（标的是 Modify/Execute），它们能在 Approval/Auto 直接撤销已记录任务。

Surface profile: workflow_undo_task / workflow_redo_task / workflow_revert_task / workflow_session_undo inspect every snapshot the target task(s) would restore. If any snapshot would author a category the active profile withdraws — a scene GameObject, or a .unity / .mat asset — the whole call is refused with SURFACE_EXCLUDED (surfaceProfile/category/operation/manualDoc/userControlled/hint at the top level, not nested under details) rather than partially applied. Snapshots of scripts, prefabs, textures, ScriptableObjects, and Editor/project settings are unaffected — those stay undoable under every profile.

DO NOT (common hallucinations):

• workflow_save does not exist → use workflow_task_end to end and save a task
• workflow_rollback does not exist → use workflow_undo_task (by taskId) or workflow_session_undo (by sessionId)
• workflow_create does not exist → use workflow_task_start
• workflow_revert_task is deprecated → use workflow_undo_task

Routing:

• For simple undo/redo (1 step) → editor_undo / editor_redo (editor module)
• For multi-step undo → history_undo with steps parameter (this module)
• For conversation-level undo → workflow_session_undo (this module)
