dsh-msg-rewind

English | [中文](./README.zh-CN.md)

Conversation rewind commands for DeepSeek Harness web.

  • /undo — roll the chat back one full turn (drop the last real user message and everything after it)
  • /rewind — pick a past user message from a dialog and cut the conversation back to it
  • Visual rewind — hover a user message bubble in the chat and click the ⤺ undo button to rewind to that point

Both the model context and the visible transcript are truncated, and the durable JSONL artifact is rewritten so the cut survives a restart.

Features

CapabilityDetail

/rewind (bare)Opens a dialog listing every user message (chronological, most recent preselected); pick one to rewind there
/rewind <seq>Directly rewinds to the given message seq
Visual rewindHover any user bubble → click the undo icon (shown with time + copy) to rewind to that message
DurableRewrites the session's JSONL+zstd artifact; the cut survives a restart

Requirements

  • DeepSeek Harness web (dsh web)
  • Node ^22.19.0 || >=24.0.0

Install

Via npm (recommended)

dsh plugin --profile web add @flow2dream/dsh-msg-rewind@0.1.2

Then restart the web profile:

dsh web

Via GitHub

dsh plugin --profile web add dsh-msg-rewind@github:flow2dream/dsh-msg-rewind

Then restart the web profile:

dsh web

Manual

Add the dependency and bundle to your web profile:

// ~/.dsh/profiles/web/package.json
{
  "dependencies": {
    "@flow2dream/dsh-msg-rewind": "0.1.2"
  },
  "dsh": {
    "profile": {
      "bundles": ["@flow2dream/dsh-msg-rewind"]
    }
  }
}

Then install and restart the web profile:

cd ~/.dsh/profiles/web
pnpm install
dsh web

Usage

In any conversation:

  • Type /undo — the chat rolls back one turn.
  • Type /rewind — a dialog opens with every user message; the most recent one is preselected. Arrow keys navigate, Enter rewinds.
  • Hover a user message bubble — a small undo icon appears next to the copy button; click it to rewind to that message.

The rewind target is the real user message (system injections such as runtime-context and skill-catalog snapshots are never treated as user turns).

How it works

  • Host (lib/index.js) registers the /undo and /rewind commands. A rewind drains the persistence coordinator, splices the live session log, resets every derived cache, rewrites the JSONL artifact, resets the agent's request-header anchor, and broadcasts session/rewind.
  • Browser (lib/client.js) listens for session/rewind, resyncs the target session's window from the host, and injects the hover undo button into user bubbles.
  • The session/rewind event is allowlisted in dsh-api-remotes's forwarded events.

Development

# from your web profile
npm install /path/to/dsh-msg-rewind

Source lives in lib/:

  • lib/index.js — host half (commands + truncation)
  • lib/client.js — browser half (resync + visual rewind)
