Attach files and folders in the composer via clipboard paste, a native file/folder picker, and @-mention path search; folders are converted to paged Markdown for the agent to read page by page. macOS only (clipboard and picker go through osascript).

Folder time machine for DeepSeek Harness: snapshot any folder, browse its timeline, roll back with one click — Git-like history without needing Git, for folders that never had a repo (game saves, app config dirs, loose documents). Snapshots are content-addressed and deduplicated, and unchanged files are not re-hashed. Automatic snapshots come in two modes: realtime (fs.watch — one version ~8s after the last change, so a save-all or a build counts once) and timed (checks every N minutes, stores only when something actually changed; identical content never adds an empty version). Empty folders are recorded and recreated on restore. Every restore takes a safety snapshot first, so a rollback is itself undoable, and exact-mode cleanup only removes files and empty folders — a non-empty folder is never deleted. Ships a folder_timemachine model tool (status/history/diff need no approval; writes ask first) plus a floating panel with the timeline, one-click restore and mode switching. Pure JS, zero runtime dependencies, 110 tests included.

Session map: a fork-tree canvas over DSH sessions, and a Settings page that clones a Git repository into a new workspace. The canvas is reachable from a session-header toggle and two right-side tabs, and from a conversation tab that is off by default; it starts on the current session's own tree, growing downward, with wheel pan, Ctrl/⌘-wheel zoom, a subagent-session filter and a per-session overview of turns, steps, model time, tool time, output tokens and running state. The clone page takes a repository address and a remembered parent directory with a native folder picker, offers a per-clone shallow switch (off by default), runs git clone on the host, and registers the cloned directory as a workspace.

Archives the sessions of a workspace when its folder is deleted or moved away, or when its registration is removed, and restores them when it returns: unarchives only the sessions it archived itself, re-attaches every member its ledger recorded (including sessions you archived manually, whose archived state is left unchanged), and adopts ungrouped sessions whose working directory is that workspace path.

Cross-agent session relay: a compact "Relay" chip in the composer toolbar unfolds a floating workbench to browse recent sessions of eight external agents (Claude Code, Codex, OpenCode, ZCode, Pi, WorkBuddy, Cursor, Grok); one click spawns a DSH session with the takeover command delivered and auto-switches to it. handoff: 1 protocol inbox cards are consume-once with a four-state evidence ledger; patches ride with cards; cross-machine relay via a synced folder. Settings keeps the command reference and reader toggles.

Local-folder wallpaper for the DSH Web UI: it defaults to your Pictures library (C:\Users\<you>\Pictures) and the host serves those images over same-origin HTTP, rotating one every N minutes (0-1440, default 5) in a shuffled pass with no repeats; the settings page under Plugins picks a different folder through the native system dialog, and tunes image opacity (100%), darkening scrim (25%) and panel opacity (15%) with changes applied live. Dialogs, modals and menus keep the default opaque background so text stays readable. Reads .jpg .jpeg .png .webp .gif .avif .bmp straight from disk, and keeps per-user settings under $DSH_HOME so upgrades never ship your folder path.

ChatGPT-like conversation layout for the DeepSeek Harness Web client: a 768px centered column, right-aligned neutral bubbles for user turns, full-width assistant text at 16/28, and rounded code blocks with their own copy banner. Adds semantic inline markup (`==confirmed==`, `!!risk!!`, `++key word++`, with bare 4xx/5xx codes highlighted automatically) and line-start check/warn/tip callouts; a fast/thinking chip in the composer that switches the model reasoning effort through ctx.modelDirectories; and sidebar contrast, where the selected session gets a tinted row with an accent bar and workspace folder icons are colored.

Token statistics for every stored DSH session: a Host service folds the durable session logs into a persisted checkpoint and serves them over one read-only HTTP route, and the Usage settings page paints the saved aggregate immediately, then updates it in the background. Days are bucketed by hour behind a date picker, next to a trailing window with per-model breakdowns, request and web-search counts; no cost or pricing model.

Multi-select clear (archive) workspace conversations and bulk-delete empty workspaces in the DSH sidebar. Workspace-level selection (tri-state), select-all, progress and failure reporting; delete keeps folders and session logs (sessions move to Ungrouped).

Orders and folds the DSH left sidebar by what is actually running — a workspace floats to the top when one of its sessions starts and keeps that place when the session finishes, only the N most recently active workspaces stay expanded, and six switches plus one count control each rule.

An always-last, collapsible Recent tasks workspace group in the DSH sidebar: a sidebar entry and the Mod+Alt+N / Mod+Shift+N shortcut start a chat in a dedicated folder, so it lands in that group instead of 未分组. The group is a genuine workspace record rather than a plugin-drawn look-alike, so collapse, rename, search and drag order behave normally, and its folder, group name, pin-last and auto-repair are live settings.

Workspace file tree and code editor in the DSH right sidebar: browse the workspace of the session it belongs to, create, rename and delete files and folders (to a trash folder by default), edit in place with line numbers and syntax highlighting (Ctrl+S saves, Ctrl+D duplicates the current line), preview images and play audio or video, list and unpack archives or pack a folder into a .zip through the system tar, search by file name or jump by a pasted path, and draw file rows with the icons Windows itself uses (SHGetFileInfo, Windows only).

Right-click a file or folder in the right sidebar file tree to add it to the composer as an @ reference (⌘/Ctrl and Shift multi-select insert a whole batch), open it with the default application, or reveal it in the system file manager. Open and reveal go through the built-in open-in-app host capability, so those entries appear unless the host explicitly reports the capability as unsupported.

Aggregated status badges on collapsed sidebar groups in DSH: a folded folder row shows in-progress / awaiting-approval / done / scheduled / review-pending counts, with numbers and hover detail. (sidebar badge / group status / aggregate)

A small pet in the corner of the interface that reads the real event stream instead of guessing: it drifts when idle, speeds up while the agent is thinking, draws a flowing line per running tool call, turns red and shakes with the error summary on a failure, and celebrates a turn that ran longer than ten seconds. The same widget is the at-a-glance busy and error indicator, so there is no spinner to stare at. The host half folds real harness events into a snapshot and the client half only draws it; it performs no content recognition, and it positions itself away from the composer so it never sits over what you are typing.

Chinese summaries for the dsh-skill-mcp-panel skill cards: each expanded card gets a short Chinese overview, a category tag and a few bullet points, while the English description the panel already renders is folded behind a "原文" toggle. Skills missing from the bundled map are translated on demand by the host with your current default model and cached on disk, keyed by a hash of the original text, so a new skill needs no manual entry. Skills whose own description is already Chinese are skipped.

Task workspace convention: one folder per session, one PROGRESS.md per task overwritten on each update, and per-task git once the task runs long.

Skill browser and switchboard for the DSH web GUI: a sidebar entry lists skills from configurable source directories as cards, clicking a card opens the full SKILL.md, and the per-card switch writes disable-model-invocation and registers or removes that skill in the agent skill catalog, so the model can load exactly the skills that are switched on. It also recognises WorkBuddy expert-team folders and shows avatar, tags, quick prompts and members, registering its lead prompt as a skill when switched on. Source directories are editable in the panel.

Knowledge-point notebook for DeepSeek Harness: turns a Markdown notes folder into a card canvas — folder = chapter, file = section, body = knowledge points — with masked-answer questions for self-testing, KaTeX formulas, Mermaid flowcharts, a mind map view and in-panel editing.

Move a session to another folder, permanently delete it, or AI-rename it from the Web UI — by dragging a session row onto a folder title or from the session menu. Moving rewrites the session header cwd, relocates the persisted log and updates workspace accounting so history travels with it; deleting stops running agents and removes the log, projection-cache row and workspace accounting. The same three operations ship as agent tools: workbench_session_move, workbench_session_delete and workbench_session_rename_ai.

Adds a 最近 (Recent) section below the workspace list in the DSH web sidebar that flattens the newest sessions of every workspace into one timeline, reusing the session rows and hover cards the shell already renders, paging in earlier sessions as you scroll, and folding the workspace list itself to the five folders with the newest history. Requires DSH ^0.2.0-rc.1.

Replaces the shipped sidebar workspace browser with Recents, a project editor that adds extra source folders, and pin, rename, fork, and archive row actions.

SSH workspaces for Linux/macOS with SSH config import, remote folder selection, and file tools, Bash and persistent remote terminals following native DSH session permissions.

Plays a Windows system sound when the agent opens a question dialog, when a tool asks for permission, and when a conversation turn ends, plus a fish_beep tool to trigger a sound on demand. Custom audio folders are supported.
