Sessions & Messages

Move sessions across workspaces by drag-and-drop with true in-place migration; recover orphaned or unregistered sessions; re-point stale workspaces after folder renames. IDs and history stay intact, with per-step backup and rollback.

Recall, edit-and-resend and regenerate, plus in-conversation versioning: a timeline of every rewind, artifact rollback (git-first, snapshot fallback), a fork map of explored paths, session lineage, and a real-time watchdog that snapshots the log at the first sign of concurrent writes. Edits auto-stop the running agent (official cancel/whenIdle) so rewinds never corrupt the durable log or break /compact.

DeepSeek Harness plugin that manages archived sessions and the trash from the settings panel.

Consolidated toolkit for session identity, global & workspace prompts with referenced files, session auto-resume, UAC-free web restart, and peer-session messaging.

Diagnose and safely repair corrupted DSH session history: raw zstd/JSONL validation, tool-call ID repair, single-slot pre-repair backup, restore, and an audit trail.

Inline preview for \[图片: path] image bridge markers: after the marker renders, the image shows in chat automatically, keeping long instructions out of the conversation.

Conversation history rail on the left edge of the chat: each tick is one real user request, hover to preview its text, click to jump to that turn.

Requires DSH 0.1.6-alpha.2. Annotate completed assistant replies, submit multiple drafts with official composer text and attachments as one Session message, navigate linked model replies, and use Settings to hide selected reasoning or tool details without changing stored events.

Provides Codex-style session message folding for DeepSeek Harness.

Cross-session reference (mention) plugin — paste @[label](dsh-session:…) into any session, including one in another workspace, and the host injects the referenced session snapshot for the model to read; includes a one-click copy-reference button.

Cross-session archive: overview workbench, folded timeline, subagent lineage, full-text search, rule+LLM summaries, ZIP export, live tracking. Native session-page embeds: turn rail, docked right panel (live mode, pinned to original session on switch), rename (official-synced), conclusion digest, health monitoring + persistent header chip (idle / active / tool-wait / stalled). dsh v0.1.2+: fuses with the official TurnNavigatorRail — vector-icon info chips (duration, tool calls, errors, thinking) plus lazy tool distribution inside the official preview card, right-click opens the workbench; the classic piano-key strip is on by default and delegates unloaded-turn jumps to the official auto-load engine; the official rail can be hidden entirely. Settings dialog section with 10 tunable behavior params.

Session row menu extras for DeepSeek Harness: pin sessions, copy session id, export structured Markdown, and permanently delete sessions.

Imports chat.deepseek.com web conversations into DeepSeek Harness as resumable sessions, from a settings-page UI.

Project and session organization with multi-folder groups, attention summaries, grouped chat search, native folder picking, pinning, favorites, ordering, and an archive center.

Auto-repairs the messages array after a tool-dispatch crash (orphaned tool_calls / tool messages), preventing 400 INVALID_REQUEST session lock-ups.

Take over the system input shortcuts for the chat input box and configure behavior independently for each shortcut.

Four-module session companion: smart conversation export (Markdown/PDF/JSON/PNG long-image with privacy redaction and batch ZIP), context handoff summaries with template save/import, API cost optimization (live official pricing, peak/off-peak scheduling, daily/monthly budgets, model routing), and global conversation search with in-chat find (Ctrl+F, CSS Custom Highlight API).

Archived-session manager for the DSH Web GUI: search titles and message content, tag/filter sessions, read logs, restore sessions, and export ZIP archives.

Message recall (撤回) plugin for the DSH Web UI: one undo button on each user message that removes the turn and everything after it, durably, without reverting code changes.

Cross-session agent-to-agent messaging for DeepSeek Harness — address another session by name and deliver a message into its inbox.

DSH Web 输入历史插件：Ctrl+Up / Ctrl+Down 像终端一样召回与切换已发送消息，零核心改动

DeepSeek Harness 的跨会话引用(cue)插件

Search, list and read past and current sessions through the harness's own `sessionQuery` service: uses the SQLite FTS5 index where a deployment enables it, and falls back to a bounded newest-first scan where it does not.
