Plugins

Turns one plain-language request into a live workbench window: a sidebar panel asks a few clarifying questions, the model writes a single-file HTML artifact, and the plugin mounts it in a resizable floating window or a standalone browser tab. Declared window actions are recorded as info-level project journal entries (without their payloads), and workbenches can be imported, exported, or installed from a market index.

Interactive cards in replies, built from a fixed catalog of 31 components (sliders, inputs, sortable tables, charts, function plots, typeset formulas, tabs, checklists, flowcharts, quiz buttons, an animation player): controls recompute in the browser without another model call, and the model never writes HTML or JavaScript. Includes a calculus engine (integrals, derivatives, limits, sums, roots, Taylor polynomials) and a bundled skill that teaches the model when to use a card.

Moves Settings out of the sidebar footer account menu into its own row at the top of the sidebar, hides the 新会话 new-session button, and hides the sidebar footer: the account launcher, the footer settings cell, and the plugin-runtime badge. Cmd/Ctrl+N still starts a session and Settings is still reachable.

Windows floating status lamp outside the DSH window: a borderless always-on-top glowing orb on a fully transparent background — green with a breathing halo while tasks run, orange shaking for approval, blue floating for your input, dim grey idle, dark grey host offline; hovering lists each session's latest task, drag to move, and the lamp self-extinguishes within seconds when the plugin is switched off.

Sidebar workspace panel that switches between running tasks and all conversations, shown as one freely sortable card list with per-card pin, rename, copy ID, fork, stop, and archive actions.

Renders the open conversation's Mermaid diagrams as a right-sidebar page, one card per diagram, each clickable to open full screen with zoom and pan; the chat's own code block is left untouched, so copying or quoting the source still works.

Windows-only power card injected into the DSH page: the artwork carries two hit zones (left shuts down, right restarts), the first click only turns the card into a yes/no question and the second click fires, and the restart engine stops only this instance's process tree, waits for the port to free, relaunches outside the host's Job Object and confirms the new instance answers on the plugin's own status route.

Folder-scoped sidebar for DSH Web: by default only folders you load are listed with their sessions; unload a folder without deleting its registration, mark folders to load at startup, and opening a session loads its registered workspace so it does not fall into Ungrouped.

Split the DSH conversation area into unlimited native panes — side by side, stacked, 2×2 and an automatic grid — each a real session with its own composer, streaming and approvals.

Find bar in the sidebar text preview, with whole-file match counts for plain text and code, highlighted hits, and jumps between them.

Adds a session-scoped context window selector next to the reasoning-effort row in the DeepSeek Harness model popup: a pill showing the effective window opens a dropdown of presets below the model default, the choice applies to the next request of that session only, and a new session falls back to the profile default. It writes no config file and appends nothing to the session log.

Renders an Agent Teams swimlane canvas above the composer: lead centred with members below, tasks laid out in lanes by longest dependency path, and four SVG connector families drawn as dashed paths (task dependency as a cubic bezier from the upstream card edge to the downstream card edge, lead bus, peer bus, member-to-task tether). Cards are absolutely positioned DOM, connectors are one SVG layer sharing the same geometry constants. Layout constants and path algorithms are ported from cc-haha. Reads the live per-session agentTeam projection (roster, shared tasks, dependency edges, running state) and falls back to the session todo list when the session has no team; team messages are not part of the projection yet, so the communication panel shows an empty state. Body colours come from host theme tokens; the eight member identity colours are the deliberate exception — fixed hues mixed with the theme accent via color-mix, declared as CSS variables because the same values feed an SVG stroke attribute that rejects colour functions. Ships zh/en dictionaries with identical keys.

Live preview inside the sidebar session hover card: what the session is doing right now (running tool with elapsed time, thinking, last tool duration), an attachment thumbnail with click-to-enlarge, the latest user prompt and assistant reply with injected system scaffolding stripped out, a recent-tool icon strip, turn count plus token totals plus model name on one line, and a 12-item settings page (11 switches plus a slider) persisted to the profile.

Runs a chosen power action (shutdown / restart / hibernate / sleep / lock / logoff) once every Agent session and background job has gone idle: the plugin samples in-process sessions once per second, counts running sessions as always busy, checks running background jobs through a configurable option (considerJobs, on by default, shown with its live count in Settings), waits a confirm window and then a cancellable countdown, and shows a draggable bottom-right card with the current phase and remaining seconds; the enable toggle never survives a host restart, any newly started session or Cancel aborts the countdown, and if the agents service is unavailable the machine is treated as busy so nothing ever fires. Windows only (the built-in shutdown / rundll32 actions); every action except none degrades to none elsewhere.

Unofficial Claude UI-inspired model and reasoning-effort selector using the current model's available levels, with animated purple pixel effects.

macOS arm64 only; requires dsh-pet installed (the bundled binary is a closed prebuilt). Desktop switch for the dsh-pet pet: one click to show or hide it, and it can start DeepSeek Harness when that is closed.

One stylesheet plus two small DOM patches that line third-party sidebar entries up with the host: matching row height, padding and icon size, one consistent active background, and mutual exclusion so the cron panel and the host panels never overlap.

Windows only; needs PowerShell and the bundled install.ps1. Adds an interface menu to the left of the model selector with three actions that run immediately: reload the interface, restart DSH, and close DSH. The Windows build ships no built-in reload or restart entry, so this adds one.

One-click screenshot button that floats over every DSH page, with a second one in the composer tool row: it captures the DeepSeek Harness window (or the whole desktop with a modifier) using the host capture tooling and puts the PNG where it is useful — straight into the composer draft as an attachment, or on the clipboard when no composer is mounted. Windows-verified, with macOS and Linux backends; no dependencies and no build step.

Hold Ctrl and roll the mouse wheel to zoom the whole Harness Web UI around the pointer, 50-200% in 10% steps; Ctrl +/- and Ctrl 0 from the keyboard; a bottom-right chip and a Page zoom row in Settings → General show and reset the level.

Adds a Restart button beside the permission control in the composer toolbar that relaunches DSH in one click, so freshly installed plugins apply without closing and reopening the app.

Keeps the DSH desktop window the size you left it: records the last outer frame of the main window in physical pixels and restores it, centred on the work area, on the next start - and it acts before the window is ever shown, so the boot animation plays at the right size. The settings page offers 12 presets (1024x768 to 3840x2160), free-form custom width and height, a centre-on-restore switch and an apply-now action; a choice takes effect immediately and persists. Resizing goes through a small helper executable compiled on the user's own machine: the C# source ships inside the plugin, is built on first run with the in-box Windows csc.exe (measured ~110 ms once, cached next to the state file, ~90 ms to start), and falls back to a short-lived powershell.exe process when that is not possible. The package ships no binary, declares no npm dependencies and makes no outbound network request. Windows only.

Adds a Restart row to the desktop app's sidebar foot beside Settings that restarts the app and reloads the page onto the newly installed plugin bundle.

The writable half of the right-sidebar document preview: edit and save any text file in place. Every save carries the version that was opened, so when the file changed on disk during the edit it stops and asks instead of overwriting. The preview toolbar gains an edit button and a two-step delete button. A separate File editor sidebar tool brings its own file tree: create, rename or move, copy, cut and paste (including a file taken from the system clipboard), delete, and drag to reorganize. Two renderer bands cover 107 plain-text, config and source extensions; the second is offered only as an open-with choice, leaving the shipped Markdown and highlighted-code views as the default. Mutations run through the plugin own trusted host routes, behind the connection fence, the workspace containment check and the sandbox policy.
