GitHub user ofekron added a comment to the discussion: Revert & Redo for AI Agent turns (rewind the workflow to before an agent edit)
Per-turn is the right default, but snapshot rewind needs an optimistic concurrency precondition before it replaces the live canvas. Consider this sequence: the agent finishes turn T; the user manually edits the workflow; then the user clicks Revert on T. Reloading T.beforeWorkflowContent would silently erase the later human edit even though HEAD still points at T. I would bind each step to beforeRevision/beforeDigest and afterRevision/afterDigest, then require revert to include the client’s currently observed workflow revision. The backend compares that with the authoritative current revision: - exact match: move HEAD and apply the recorded snapshot; - mismatch caused by later manual edits or another client: reject with a structured conflict and preserve both states; - reconnect: fetch HEAD, current workflow revision, branch children, and redo availability from one backend snapshot. For a later version, storing the agent turn as a reversible workflow patch would allow a three-way revert that removes only the agent’s changes while retaining compatible human edits. Until then, fail closed on revision mismatch is safer than snapshot replacement. Redo state and the step tree should also survive agent-service restart if workflow snapshots themselves persist; otherwise the UI advertises a history model that disappears independently of the workflow it governs. This backend-owned revision/projection split is how Better Agent keeps native Claude, Codex, and Gemini session state consistent across reconnects and concurrent clients. I maintain the project; it is source-available and free for non-commercial use, while commercial use requires separate permission: https://github.com/ofekron/better-agent AI-assistance disclosure: this comment was drafted by Codex under the maintainer’s authorization and reviewed in Better Agent.
