Plugins

Adds a Continue button to the composer dock and resumes automatically when a turn is cut off by a network drop or an upstream output-limit cut. A resident link monitor asks every 10 seconds whether the network is back, because the link returning fires no event, and a turn that completes normally counts as proof the link works. The click goes through the host submission pipeline — beginSubmission plus session.prompt — so the message carries real user attribution instead of faking one, and a genuine refusal is reported rather than retried. On startup it also scans recent session logs for both fingerprints of a host that left mid-turn: an unclosed turn, and a turn closed as disposed, which is what a normal shutdown writes. A turn the user stopped by hand is never resumed.

Session board orb: live thinking and tool progress per session, task duration, context usage and 12h/30d usage stats; click through to any session.

Smart naming for sessions and workspaces: one click asks the profile model for short name candidates from the item's own content, then renames in place.

Pins the first prompt of the current session in a scroll-proof bar above the conversation: one-click copy, a panel listing every prompt you sent (click a row to jump straight to that message, paging back through history when needed), and ten switchable looks (four of them light) you pick from inside the panel.

Adds a management page for the official DeepSeek Harness ACP subagent provider, with one-click presets, a read-only connectivity check, live switches for all three entry points, and online preset updates.

Rewrites the composer draft into a tighter prompt in one click and restores the exact original in another, running on Harness's own models by default or any OpenAI-compatible endpoint, with an editable polishing prompt.

Adds a button to the composer that restates your draft, then asks a few questions with clickable options — every question offers an "I don't know, you decide" escape — and only then rewrites the draft into a request an agent can start on. The whole flow can be finished without typing, and it never sends for you.

Middle-click closes a session or a sidebar tab in the DeepSeek Harness Web UI. A session closes through the row's own archive action, so the confirmation for running work and the undo notice stay exactly as the Harness renders them; a tab closes through its own close control, leaving the rule that a lone guide tab cannot be closed untouched. The gesture settles on press-and-release on the same element, so a middle drag never closes anything. Two switches on the plugin's own Settings tab turn each half off, remembered per browser.

Windows only: a night-and-moon themed floating button (a sleepy DeepSeek-chan whale mascot, awake/sleeping artwork) in the bottom-right corner arms the plugin — click it to power the machine off once every root Agent session has gone idle, and click it again to disarm. The button is draggable (position remembered in localStorage), automatically dodges other plugins' corner popups, and survives the frontend re-rendering it away. When the batch finishes a 60 s cancellable countdown starts (configurable 10–600 s) with the remaining seconds on the button and a matching banner: clicking Cancel runs shutdown /a and disarms the mode, and any new session starting during the countdown aborts it. A right-click menu on the button switches the shutdown condition between only-on-success and shutdown-regardless, persisted across restarts in $DSH_HOME/deepseek-chan-sleep-shutdown.json. Zero runtime dependencies.

Prompt enhancement for the DSH Web GUI composer: pick a style before generating (logic-only, structured, or concise), or supply or clear a custom system prompt in settings; a sparkle button or Shift+Tab rewrites the current draft through the harness model, streams the result into an inline preview (original vs enhanced) with a live thinking timer, fills it back with one click, keeps an undo bar, and offers settings for model route, temperature, length limits, context awareness, undo-bar behavior and shortcuts.

Puts a More row at the end of the sidebar main panel list and lets you decide, entry by entry, which panels stay visible and which move into it: a menu lists every entry with a one-click switch in either direction, a search box filters long lists, and a single Restore all clears both kinds of key. Also hides the footer action buttons, keeps the plugins entry un-collapsible, and writes each choice to the profile config so it survives a restart.

Rewrites the composer draft into a precise prompt with a configurable model and a fully editable rewriting instruction; reads the content behind @file, @folder and @session references for context and keeps the reference chips intact; offers a one-click undo that restores the text you wrote yourself, and places the button in either composer toolbar with an adjustable colour and size.

Interactive HTML or flowchart cards inside the conversation: the tool blocks until the user submits, then returns the clicked action, fields, comments and card state.

Composer infinity switch: while the highest reasoning effort is selected, one click appends a configurable notice to the system prompt.

DeepSeek Harness 对话内容搜索插件：在 Web UI 内搜索当前与全部历史会话的消息文本，点击结果自动切换/滚动定位到命中消息并高亮，面板内展示命中消息的前后上下文。Conversation full-text search for DeepSeek Harness: search the current and all historical sessions, click a hit to auto-navigate, scroll to and highlight the matchi

Drive DSH's own built-in browser (the right-hand Sidebar's Browser tab) from the agent: list tabs, open, navigate, read the page, run JavaScript, click, fill forms, log in, and look at pictures or the pane itself with vision. No second Chromium process.

Model provider for DeepSeek Harness (DSH): WorkBuddy, Trae, Qoder, ZCode and your Claude / Codex subscriptions behind one OpenAI-compatible endpoint, with a lightweight settings panel and the full management interface one click away. · DSH 的模型提供方：设置页轻量管理，

Markdown display enhancements for the DSH Web chat, applied on top of the host renderer rather than replacing it: code blocks become cards with a language label and icon-only wrap and copy buttons, long code blocks, tables and Mermaid diagrams fold behind an expand control, Mermaid fences render as SVG with a diagram and code toggle, a fullscreen viewer with wheel zoom, drag and double-click to fit, and SVG or PNG export, tables get a sticky header and CSV or Markdown copy buttons, and a settings panel adjusts the diagram palette, code font size, the default diagram view and the three fold thresholds.

Action cards: the agent proposes a concrete action (create a file, edit a value, run a command), you edit it and apply it in one click, and the Host executes it and reports back.

DeepSeek Harness (DSH) plugin — connects DSH to MATLAB and Simulink through the official MathWorks MATLAB MCP Server, injects MATLAB/Simulink Agentic Toolkit skills, and provisions everything with one click.

Adds a Restart card to the harness settings: one click hands the restart to the DeepSeek Harness launcher (`Launch-DeepSeekHarness.ps1`), which replaces the running web process, and the page reconnects itself once the new instance answers. Windows only; without that launcher the button reports an error instead of restarting.

Session board in the left sidebar: every chat session's current work, todos and progress, with a searchable overview heatmap and one-click navigation back to the session.

Polish button in the composer that rewrites the draft with the model the current conversation already uses: four styles, a fidelity guard that keeps every concrete fact verbatim, one-click revert, and no API key of its own.

Folders for the DSH Plugins page: group installed plugins, toggle a whole group, batch move with undo, search across groups, long-press drag to reorder, reinstall removed plugins from their record, and restart Harness with one click.
