Plugins

Replaces the new-session hero with a combined picker: role cards for the agent presets and a workspace card, collapsed into capsule buttons that expand into two scrollable rows.

Sparkle button immediately left of the model selector that rewrites the composer draft into an executable prompt in place, modelled on WorkBuddy: the host calls the conversation LLM with a prompt-engineering system prompt, multi-level undo keeps up to 8 previous drafts, and a token-level diff card shows added and removed spans, the number of changed spots and the net character delta. Runs on the session model, is disabled while the draft is empty, and keeps the browser-session cookie fence in front of the LLM call.

Live decode speed (tok/s) pill in the composer status bar that tracks the currently streaming response.

Adds an installed-plugin picker beside the composer: drag a plugin name into the prompt at the drop point, open a draggable plugin rail in the right sidebar by double-clicking the entry, and choose which plugins (and remarks) appear in Settings.

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.

Adds a composer button that rewrites the current draft into a precise prompt in place, in one click, with a revert action.

Renders model answers as interactive cards inside DeepSeek Harness chat, with 24 whitelisted components and persistent turn cards.

Grouped skill picker for the composer. A button beside the input box opens a panel that browses every installed skill by scene (research, office, data, writing, media, dev), with auto-classification for new skills, Chinese annotations, search and drill-down; picking one inserts the /skill-name gesture.

Publishes the desktop shell's file-path bridge as the host-path seam the composer reads, so files and folders dropped into the composer become @path references instead of uploaded copies (images still upload through the native image channel).

Copies selected assistant text to the clipboard and shows a Comment chip that opens the inline comment box in DeepSeek Harness; the right-click quote menu and Cmd+L still work.

Predicts your next message after each completed turn and shows it as ghost text in the composer: press → to accept, or keep typing and finish it word by word with Ctrl+→, Esc to dismiss. The prediction model follows the session by default or can be picked in the settings card, which also has an on/off switch and a speed test.

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.

Codex-style paste collapse for the DeepSeek Harness composer: a paste of more than 1000 characters becomes a `[Pasted Content N chars]` placeholder, a second paste of the same size is numbered `#2`, and the host expands it back to the full text before the model reads it, so the model still receives every character. A pill on the top edge of the composer shows the preview, the sent message shows the same pill, and clicking either opens the whole paste in a side panel with a copy button. Pure in memory: nothing is written to disk and no token is saved.

Codex-style reasoning-effort card for the composer: takes over the model selector and shows the current level, the model row and a segmented slider over the model's own adapter-provided levels, with a model list, a reset, and a purple aurora with twinkling particles at the maximum level.

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.

Composer model selector grouped by provider: pick a provider card, then drill into that provider to choose a model, with cross-provider search and Reasoning Effort kept.

Makes the provider groups in the composer model menu collapsible, keeping only the provider of the current model expanded.

Native, instant region-screenshot button for the DeepSeek Harness composer: one click freezes the screen, a WeChat-style overlay (gray mask, green selection) appears, and the cropped PNG is inserted into the current draft. An optional eye toggle hides the whole DSH window before capturing, then restores it. No ms-screenclip, about 10 ms per drag frame, coexists with voice input. Windows 10/11 x64 only; the first capture compiles a helper with the built-in .NET Framework csc.exe.

Visible terminal panel that streams the agent's shell commands into an in-app terminal and lets the agent capture the terminal screen as text.

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.

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.

Composer prompt enhancement for DSH Web: a ✨ button rewrites the current draft in place after asking only about genuine ambiguity, and an empty composer shows a grey next-message ghost that Tab or a click fills into the draft without sending.

Adds a sticky effort slider inside the composer model menu to select reasoning levels, with generic stops for custom models.

Personal task board for the DSH Web GUI with a two-month calendar of colored timeline bars and day tasks, a daily checklist, a seven-day week view with completion checkboxes and drag-to-reschedule, a draggable 24-hour day timeline, ordered subtasks, per-day completion for long-term tasks, and AI extraction of tasks from natural language.
