Sessions & Messages

Branch-based message editing, reroll, retry, and a version timeline.

Keep branching from any completed answer at any depth while the main session stays untouched.

Branch-based message editing / reroll / retry / version timeline.

Session Workbench: full-text search past sessions, recall up to 3 as @references, and manage conversation-view tabs (show/hide + drag reorder).

Real session deletion with trash and restore, archived cleanup, and batch delete from settings.

Session-level superagent: watch one GitHub repository and wake this session when an issue or pull request changes; requires a logged-in gh CLI, and the credential never reaches the model.

Configurable deterministic session titles for DeepSeek Harness from semantic prompt fields and templates.

Manages archived DSH chats with conversation search, restore, and confirmed safe permanent deletion.

Share your conversations with one click.

Rewind a DeepSeek Harness conversation and its workspace together, without touching Git: every rewind is a fork, /redo reverses it, and a Rust engine snapshots in milliseconds.

Select text in a committed DSH response to open an independent, persistent, read-only multi-turn Topic bound to source-session evidence and project files while the source Agent keeps running.

Permanently delete DSH conversations with optional recursive deletion of forked and subagent sessions.

Cross-instance message and event handoff between DSH instances via an interconnect server.

One-click prompt enhancement in the composer — rewrites the draft into a structured prompt (role and goal, executable steps, output format, acceptance criteria, edge cases) with before/after preview, fill-back, and undo. Never changes intent, never fabricates requirements.

Archive, restore, permanently delete, and move DeepSeek Harness sessions across workspaces from one unified settings panel.

Share DSH conversations.

Cross-device session sync for DeepSeek Harness — syncs sessions and settings between machines through git.

Four-source migration wizard: move Claude Code, Codex, OpenCode and Hermes sessions, memories, skills, instructions and slash commands into DSH (/move wizard with approval gate and idempotent move.json, resumable sessions).

Workspace-based archive management with scoped content search, conversation previews, tags and notes, ZIP backups, lineage graphs, confirmed permanent deletion and retries, and official Host updates.

Edit a sent message to rewind and branch the conversation from that turn, switch versions with a counter under the bubble, and browse every branch in a turn-level version tree.

DeepSeek Harness Default System Prompt Management Plugin: Browse, search, and override the final system prompt assembled into each session round within the Web GUI "Settings".

Search and manage archived and unarchived chats with read-only previews, tags and notes, workspace archiving, ZIP backups, origins and branches, manual residual-chat checks and automatic update checks. Retains legacy Recycle Bin recovery without automatic cleanup.

Reference workspace files, DSH sessions, and historical ChatGPT, Claude, Gemini, DeepSeek, Grok, and Kimi conversations from the unified DSH @ menu.

While vibe coding, save an answer you may need later, use Side Chat for a question that suddenly comes up, or open a related conversation for deeper work without losing focus on the current task.
