dsh-chat-plus is a DeepSeek Harness session-operations plugin. It brings WorkBuddy-style in-session regeneration and reply-version switching to DSH, with message editing, rollback, soft deletion, and a session recycle bin.

Why it exists

DSH sessions use an append-only log. The plugin uses the official surface-replacement contract to remove inactive content from the model context while retaining the raw history. Switching a version appends the selected historical surface nodes back to the active session, avoiding sidebar fork sessions and core-source changes.

Features

In-session reply versions

• Regenerate the latest reply without creating a new sidebar session.
• Switch versions with < 1/2 > buttons or the left/right arrow keys.
• Show the active model name and generation time.
• Warn before regenerating a tool-using reply because tools may run again.
• Continue from the selected version with only that version visible to the model.

Questions, replies, and rollback

• Select user questions and assistant replies for batch deletion.
• Delete a reply with its reasoning and tool calls while keeping the question.
• Delete a question together with all reply versions in that turn.
• Edit any historical question in the official composer; later turns require confirmation before removal.
• Roll back from a node and restore the original question to the composer.
• Paste images/files into the inline editor; DSH validates/stores pasted images, and historical attachments can be retained.

Session recycle bin

• Add Delete session after Archive session in the session menu.
• Running sessions show a stop-and-delete confirmation.
• Open the recycle bin from the workspace sidebar footer.
• Restore, permanently delete one session, or empty the bin.
• Cascade archive, restore, and permanent deletion to child subagent sessions.

Names

• Project: dsh-chat-plus
• GitHub repository: whoishuhu/dsh-chat-plus
• DSH plugin ID / bundle: dsh-chat-plus
• Display name: Chat plus / 对话增强
• npm package name: the manifest name is also dsh-chat-plus, but it is not published. That npm registry name is occupied by another project, so install through the GitHub repository, DSH plugin indexes, or a local bundle.

Architecture

See ARCHITECTURE.md for the Host projection, operation route, Client slots, version switching, and deletion model.

Important boundaries

• Message deletion is soft deletion: the model context and chat view hide the content, while the append-only raw log remains unchanged.
• Version switching appends the selected version back into the log, so logs can grow.
• Regeneration may execute tools again; external side effects are not automatically undone.
• Permanent recycle-bin deletion is irreversible and removes session logs, projection-cache records, and child sessions.
• The plugin owns the user-message renderer to provide its action row; DSH UI changes may require an adapter update.
