Call workflow_session_start at the beginning of the conversation and workflow_session_end when done. Later, use workflow_session_list to find the sessionId and call workflow_session_undo to revert every tracked change from that session at once.

Workflow history is persisted to workflow_history.json, so tasks survive Editor restarts. Call workflow_list to get the taskId, then workflow_undo_task with that ID to restore the previous state; the undone task can be redone later.

Yes. Deleted assets, including .cs scripts, are moved into a content-addressed file store with their .meta files, so undo performs a full restore. Asset and meta bytes are stored by SHA1 hash under Library/UnitySkills/workflow_files.

workflow_clear_history is marked as a high-risk Delete operation, so it is NeverInSemi and forbidden in Approval or Auto modes. It only runs in Bypass mode or when an allowlist entry matches, because it irreversibly wipes all history and stored backups.

Undoing scene_save restores the on-disk .unity file, but an open scene must be reloaded to take effect. Objects created in never-saved scenes fail undo after restart, and external side effects like Package Manager operations cannot be rolled back.
