DeepSeek Harness Rewind Plugin: Recover a Deleted File and Undo the Rewind

Description and use

The dsh‑filesnap plugin restores a deleted file and rewinds the conversation in DeepSeek Harness, with a redo command to reverse an incorrect rewind.

A coding agent deletes a needed file and the conversation must be restored to a prior state without losing the original dialogue.

The plugin restores deleted files and conversation state, and allows reversing an incorrect rewind, all without a Git repository.

Install dsh-filesnap via dsh plugin --profile web add dsh-filesnap and restart the profile.
Create a file, edit it, then delete it in a disposable workspace.
Run /rewind or /rewind <turn> to restore the workspace to a captured point before the deletion.
Verify the file exists and contains the expected text.
If the checkpoint was too early, run /redo in the child conversation to revert the rewind and return to the original conversation state.
Check both the file contents and the active conversation after each step.

FileSnap needs an earlier capture to recover that version. Installing it after a deletion cannot recover a historical state it never captured.

Redo reverses the rewind using the rescue state recorded before restoration. It returns the original conversation as the continuation target.
