Sessions & Messages

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.

Git-style conversation branching that mirrors how real programmers collaborate: a secretary root branch dispatches tasks to child branches with their own contexts, merging back only compressed summaries via squash or rebase; ships /branch commands, a branch tab, branch-to-branch messaging, and a governance baseline pairing each session branch with a git worktree.

Manage conversation records from the DSH web GUI settings page: delete a whole session (archive plus physical log removal) or a single message (deleting a user message cascades to its assistant replies and tool results). Running and current sessions are protected.

Context Assembler plugin for DeepSeek Harness: topic-block context assembly, water-pressure topic splitting, tool trace/rewrite, reality recall injection and handoff planning.

Adds per-Workspace category trees to the Web sidebar, with nested categories, drag-and-drop session assignment, category-scoped session creation, and category deletion that archives contained sessions.

Browser-local prompt library with a composer picker for injecting multiple session-scoped system prompts, branch inheritance, bilingual UI, favorites, and JSON backups.

Move a session to another folder from the Web UI via drag & drop or a menu picker, permanently delete a session with a risk-consent dialog, and AI-rename a session by summarizing the whole conversation (typo-aware). Each action also ships as an agent tool.

Pause / resume / cancel the in-flight conversation task from the composer area: forced pause interrupts immediately and remembers the interrupted tool, safe pause lands after the tool or reasoning finishes, resume asks for confirmation, and the default pause granularity is configurable in the settings.

Cross-session agent messaging for DeepSeek Harness with session discovery, offline delivery, delivery receipts, and sender-session navigation.

File claim/release protection for parallel DSH sessions on the same workspace (heartbeat stale takeover, pending 3-way merge area).

Two-way sync of DSH sessions, workspace mappings, settings and patches between machines through your own private GitHub repo (API keys stay machine-local).

Move, archive, restore, portable backup/export and import sessions across workspaces in the DeepSeek Harness web UI.

Piano-key style in-conversation navigation bar: one key per user message, hover preview tooltip, click-to-jump across full history. Official dual-face dsh plugin, no dsh source changes.

Archived-conversation manager for DeepSeek Harness: view archived conversations grouped by workspace, restore them, and reveal their transcript folders.

Off-peak message scheduler: turn on valley mode and the composer queues your messages until DeepSeek off-peak hours (half price), then auto-injects them into the session and gets replies. Native-look composer, hotkeys (Enter queue / ⌘+Enter send now / Esc exit), per-session toggle persisted across restarts.

Browses checkpoints produced by dsh-checkpoint-rewind as a timeline of time nodes and shows per-file line diffs between any two of them, with trace replay from session logs (no snapshot producer needed) and preview-first workspace rollback with single-shot undo, via /diff and /rollback commands, a JSON HTTP API, and a GUI panel.

Import pi / opencode / codex / claude-code sessions, chat history, and agents into DeepSeek Harness — one-click Sync button, slash commands, session-start migration prompt

归档对话查看 (archived-conversation-viewer)：在 DSH 设置页查看、恢复与删除归档会话的 Cordis 插件

DSH Session Manager: manage conversations, archive/restore, delete safely, open record folders.

DSH web client plugin: open a session directly from the URL (?session=<id>).

DeepSeek Harness 多电脑同步：通过自己的 GitHub 仓库同步会话、附件、设置和工作区文件。Sync DSH sessions, settings and workspace files across computers.

Session deep links, full session export (markdown/JSON), approved cross-session messaging with pairing, and team roster, rotation and recovery tools for multi-session work.

Smart session titles for DSH: after each conversation turn an independent auxiliary LLM call summarizes the full user+assistant transcript into a title that follows the session's real topic instead of echoing the first message; the first message is titled instantly, failed built-in titles auto-retry on later turns, manual renames are never overwritten, and subagent/fork sessions are skipped.

Switch the language of the agent's thinking/reasoning process (chain-of-thought): 简体中文, English, Русский, Français, Deutsch, Español, 日本語, 한국어 and more, or auto-follow the system locale. Adds a Settings → General row, a system-prompt instruction (per-prompt assembly, applies to new sessions), and the /thinking-language command.
