deepseek-harness-rewind

The most stressful moment when an AI agent edits your project for several turns is rarely the first wrong line. It is turn six, when you realize turn three was the right call and everything since has made things worse. You never committed per turn, and git checkout would nuke the good changes along with the bad. deepseek-harness-rewind fills exactly this gap: an undo button you can press at any point in an agent session.

After every turn ends, it silently snapshots the workspace into a dedicated shadow git repository. It never opens your project .git for writing, never fires your hooks, and never touches HEAD, reflog, or stashes. To go back, open the Rewind panel in Settings or type /rewind 3 to jump to turn 3. The workspace is made equal to that state: files created since are deleted, files modified are reverted. Before each restore the overwritten state is saved first, so undoing a restore is just restoring that saved entry. Files excluded by .gitignore (.env, node_modules, build output) are intentionally not captured, keeping snapshots lean. Storage follows git object sharing, so unchanged files cost one copy plus per-turn deltas, and stale sessions are pruned automatically based on configurable retention.

Who it is for: any developer who lets a DeepSeek Harness agent edit code or documents over many turns, especially in projects that are not committed per turn or are not git repositories at all. If you want the agent to rewind its own work when it realizes it went in the wrong direction, the exposeTool setting can grant it that ability. It is off by default, so the decision to let the agent undo stays yours.
