Plugins

Text-to-image and image-to-image for a model that cannot draw, through any OpenAI-compatible image API, with multiple providers and an automatic fallback model.

Time-based model routing: a settings panel defines weekday peak and off-peak windows and the provider/model each one uses, the choices are read from the harness registry (API keys and subscription logins alike), and a global switch decides whether that policy sets the model and reasoning effort of every request. The switch is independent per session, each session row carries a light showing its own state, and the settings panel names the model in force right now and why. A day no window matches — every weekend and holiday — uses the primary model of the first plan; the advanced thinking model is a separate axis, used only when a session itself asks for max reasoning.

Deep-space theme for the Harness Web GUI: two fully designed light and dark palettes over a seamless cross-dissolve nebula wallpaper, plus a model probe that reports which configured models actually answer and their real context window.

iOS 26 liquid-glass skin: one white-grey-blue fog field behind the whole window, a single 40px frost on top of it, a floating glass sidebar and reply bubbles. Light and dark palettes, no photo wallpaper, no dependencies (33 KB).

Adds a Matrix-inspired digital-rain startup animation for DeepSeek Harness, a rectangular light portal that opens to both sides, optional replay when the desktop window reopens, and a green UI theme with adjustable hue.

Session budget gate for DeepSeek Harness: prices every turn against the official price table, warns at 80%, stops the task at 100%, and writes a handoff snapshot so the next session can continue the work.

Extreme LLM-call compression for DeepSeek Harness: title short-circuit, in-flight dedup, 24h replay cache, and batch-merging N parallel requests into 1 upstream call via a `[[TASK n]]`/`[[ANSWER n]]` delimiter protocol - fewer API calls, less spend, same answers.

Auto-expand reasoning and tool cards, tune code-block font size and line spacing, and choose the model output language (auto, Chinese or English).

A composer switch between running always and running only in off-peak hours, set per session: a task is judged by the session that owns it, so changing one session no longer changes the others, and a session without its own choice follows a default. In off-peak mode every task, including one already running, is held at its next agent step or tool dispatch when a Beijing peak window starts (Monday to Friday 09:00-12:00 and 14:00-18:00, statutory holidays excluded), and one timer releases it at the boundary; weekends and holidays are idle all day. The holiday calendar lists every statutory day off in 2025 and 2026 from the State Council notices, and a year with no data is reported as unknown rather than assumed to be a workday.

Read-only clinic for DSH session logs: 22 named diagnostics (token waste, retry and failure loops, context bloat, cross-session amnesia, idle MCP servers and skills), each reported with a replayable evidence locator such as session.v4.jsonl.zstd#L101-L110, and each finding turned into an executable prescription — a profile-patch YAML snippet or a command with current to suggested values, risk, verification and source — plus a feedback command that retires a prescription you reject, after which the report states it was removed by your feedback. Zero dependencies, default zero egress, session files are never written.

Draws circles, arrows, boxes and text on the DSH image preview, keeps every mark selectable so it can be dragged, scaled or re-edited later, and attaches the flattened PNG to the composer at the original image resolution.

Set the DSH Harness conversation flow's font, font size and line spacing, plus the padding between the conversation text and the window edges.

Tired of going fullscreen by hand every time you open Harness? This plugin fills the screen for you - auto-maximize (keeps the window buttons) or true fullscreen on launch, then maximize / restore / minimize / always-on-top anytime. It quits only after a native confirmation dialog - Esc, double Esc, or Ctrl+Q; in fullscreen, Esc leaves fullscreen first. The window channel installs itself, so no script or Python is needed; the first install takes effect after two DSH restarts.

Enhanced right-sidebar files panel: rename, create, upload, download (a directory is zipped on the fly), copy the full path and delete from the tree; an editable document renderer for 128 text extensions with Ctrl/Cmd+S save and conflict detection; plus an independent bottom terminal panel with tabs and a quick-command library persisted under the DSH home.

A prompt optimizer in the composer input tool row: pick a category and a template, then ✨ rewrites the draft in place with one-click undo. Pick from the Basic, Context and Image categories; you can cancel a run, and it shows elapsed time and token usage. Ships 15 templates covering task-instruction rewriting, step planning, safety-research framing, system-prompt role cards, and text-to-image / image-to-image prompts; context templates read the recent turns of the session for coreference resolution. Calls go through the host model service, and a settings section exposes the model and the budgets. Output guards check that user-written constraints survive, warning rather than auto-retrying. Adapted for dsh 0.1.7 and 0.2.

Select foreign text in a DSH conversation and a Simplified Chinese translation card appears right below the selection.

Adds a manim_card tool that renders Manim Python into a playable animation card in the chat stream; the code runs in the browser on a bundled runtime, so no local Python is needed, and video export goes through the local Manim CLI when installed or frame by frame in the browser otherwise.

Select text in any Windows app and read the translation in an always-on-top card next to the cursor: streaming text follows the newest line, up to 15000 characters per request. Windows only.

Auto-pairs brackets and quotes in the DSH chat composer, inserting the closing half with the caret in between; it also wraps selected text with the typed pair and handles brackets committed by an IME.

Composer prompt enhancement for DeepSeek Harness: a button beside the model selector rewrites the draft through one auxiliary LLM call and writes the result back in place, with composer undo left intact; a /prompt-enhance slash command returns the rewritten prompt as a command result line without touching the draft; the enhancement call can be pinned to its own fast provider and model in the profile patch; the rewrite policy is faithful - original intent, language and information are kept, code, commands and paths are preserved verbatim, and nothing is invented or padded with placeholder text.

Hermes in the DSH sidebar: start and stop the gateway and dashboard, watch the dashboard beside the chat, and bridge DSH to Hermes. Windows only; requires an existing Hermes install.

Quote text selected in a DSH Web conversation, then either attach it to the current composer or dispatch it to a subagent session: the quote sits on a bar above the composer, or opens that subagent in a new pane on the right. When the target has no subagent yet, the quote is held and the composer is seeded with a spawn request, then picked up automatically once the new session appears. Client-only.

Input prediction: the likely continuation of your draft appears as grey ghost text after the caret and Tab accepts it, and after each assistant turn 1-3 clickable follow-up suggestions appear above the input box and send on click. Ghost completion, suggestions and the suggestion count can be toggled in Settings, Built-in plugins.

A 3×3 pad of saved phrases sitting to the left of the composer and tracking the input box's height: clicking a cell inserts its text at the caret as one undoable edit. Presets are editable in place, 9 cells per page up to 12 pages, and the UI follows the DSH language setting. Falls back to a panel above the composer when the window leaves no room.
