Plugins

Drives the DSH right-sidebar built-in browser from the agent side with 38 tools (open, navigate, read page text and interactive elements, accessibility tree, click, fill, select, check, key press, scroll, resize the browser frame by dragging its corner, with the page inside reflowing responsively so a narrowed frame shows the mobile layout, screenshot, full-page screenshot, PDF, markdown export, scrape to JSON, download, cookies, per-step operation records with replay and action whitelisting), serves the built-in web_search from a self-hosted SearXNG over an SSH tunnel with Tavily and a real-browser fallback, and registers a fetch provider that retries blocked GitHub URLs through measured mirrors and sniffs charset from the response header so GBK and GB2312 pages decode correctly.

Use ChatGPT Dots in a full-width DSH page with Desktop startup preload and page retention across panel switches within the same DSH session, Chinese/English theme-aware controls, reload and external-browser fallback; includes a separately applied login-persistence companion for Windows DSH 0.2.1-rc.3. After upgrading to DSH 0.2.1-rc.5, the embedded Dots page may require signing in again after restarting DSH. The current host browser does not provide login persistence across restarts, and a host upgrade may overwrite the earlier additional persistence treatment; this Dots update did not remove login-saving functionality.

Loopback relay as DSH's process-wide proxy route: web_fetch works under TUN fake-ip; a dead proxy gets same-request direct fallback, and a probe switches back.

Optional Decision API tool discovery and search-source prefetch, with per-session controls and ordinary-discovery fallback.

模型故障转移队列：P1 限额/限流/不可用时自动切到队列下一个模型继续，全部图形界面配置 | Model fallback queue for DeepSeek Harness: auto-switch to the next model when the current one hits quota or rate limits

Hybrid model router for DeepSeek Harness: declarative rules, user-configurable cost control (cost-first / quality-first / balanced), optional LLM task classifier, and failure fallback chains.

Hot-reloads DSH plugin modules without restarting the app (module-cache purge, junction-path matching, bust fallback) and registers a refresh button in the session header so the browser page loads the new plugin bundles.

Moves a DSH profile to another machine with its plugins, not only its files: packs the plugin bundle selection and the whole settings layer into one JSON file, then on restore writes the configuration back, restores local plugin sources and plugin-owned data, and installs the plugin bundles the backup recorded that the new machine is missing (plugin manager first, pnpm as a fallback).

Speaks a cue for DeepSeek Harness on Windows: a configurable phrase when an agent turn completes normally, a second phrase when the agent needs you to choose — a question, a plan approval, or a permission request — and a time-of-day greeting when a new conversation starts. A small bubble in the lower-left corner mutes and unmutes every cue with one click, with its own toggle chime. Phrases are synthesized with a Microsoft Edge neural voice (skipping aborted and errored turns, subagent turns, and rounds that a goal is still driving), cached under the DSH home directory and replayed locally, with the desktop SAPI voice as the offline fallback.

Test work framework for DSH that scaffolds a product, module and version directory tree, registers seven test_framework_* tools and four runtime skills, and adds a prompt-level gate that reports which requirement-document splits, versions, related documents and environment credentials are still unrecorded before testing starts. Requires the playwright MCP server (no fallback).

Keeps an unattended DeepSeek Harness session moving when nobody answers ask_user_question: it fronts the question waterfall, leaves a human answer untouched, and after a configurable window (120 s by default) submits the option marked (Recommended)/（推荐）, or the configured first/last fallback; plan reviews stay with the human unless explicitly enabled.

Extract Bilibili platform/AI subtitles or external/embedded/ASR/OCR fallback and render Markdown, Word, PDF, TXT, SRT or JSON with timestamps, bilingual alignment and a quality report. Requires Python 3.10+; platform/AI subtitles need a Bilibili SESSDATA cookie; OCR/ASR/PDF need ffmpeg, faster-whisper and LibreOffice or reportlab.

Windows x64 translator with a dedicated sidebar entry and Workbench / Chat interface, side-by-side text and document translation, screen-region translation, recent history, and host model selection, voice input and preview. CUDA document OCR with CPU fallback; screen OCR uses CPU. Do not enable the CPU and CUDA packages at the same time.

Built for DSH 0.2.1-rc.2 (engines.dsh pins it exactly). Technical support for Dragonfly 3D World using 2027.1 help documents and read-only searches of a detected local installation, with an explicit help-only fallback.

Registers /compact_queue, a compaction command that does not drop the request when the session is busy: it compacts immediately when idle, otherwise queues the request in that session and runs it at the session's next idle window, with a 2-second fallback tick beside the agent status event so the trigger is not missed, a 30-minute wait cap, and /compact_queue cancel to withdraw a queued request or abort a running one. Each session keeps its own queue state from a single command registration, completion and failure arrive as a collapsed notice that does not wake the model, and every ManualCompactionError code except busy is terminal so a failure is not retried. Host half only; the core /compact command is left untouched.

Tiers free-channel models into three 1M fallback chains plus a custom chain; orders them by measured throughput, drops models below throughput or error-rate thresholds, and rotates accounts. Requires an OpenAI-compatible gateway (default :8326).

Registers local Qoder, QoderCN, OpenCode, Pi and CodeBuddy CLIs as DSH subagent backends, with ordered model fallback, live progress, per-run credit display, a settings page, and slash commands. Requires the corresponding CLI installed and logged in.

Rewrites agent-issued delete commands (PowerShell `Remove-Item` and its aliases, Bash `rm`/`unlink`/`rmdir`, CMD `del`/`erase`/`rd`/`rmdir`) into system recycle-bin operations on Windows, Linux and macOS, best-effort checks scripts for the same operations before they run, and keeps no permanent-delete fallback.

DSH Cordis computer-use provider for the ZTE Nde desktop. npm install auto-fetches the musl binary built by computer-use-linux-zte-nde (v0.7.7-nde.3) into the package's own bin/ via postinstall; resolveCommand() resolves the cordis command path against import.meta.url so the mount works regardless of dsh web's cwd. Reserves the shared computer-use slot via ctx.computerUse.register and exposes MCP tools under mcp__computer-use-linux-nde-mcp__* (screenshot, list_windows, click, type_text, doctor, etc.). Two notable Nde fixes upstream of this provider: KWin caption+coords fallback for window targeting, and SnapshotCache that keeps AT-SPI single-wake per (app, pid) so Chrome is not repeatedly disturbed.

Injects your existing markdown documents (notes, rules, knowledge-base files) into every dsh session's system prompt as read-only memory — list file or directory paths in `files`; no database, no service, no write path; UTF-8 byte-budgeted truncation with line-boundary fallback, total budget, YAML front-matter stripping, and freshness timestamps.

Speaker button left of the model selector in the composer tool row — one click scrolls to the start of your newest question, marks it with a blinking caret and reads from there through the newest agent reply (dsh-tts, browser voice as fallback); press-and-hold the icon and then click anywhere on the page to pick another reading start position; press-and-drag-up opens a vertical mixer for in-page media volume and system output volume.

Low-token web search that returns only {title, url, snippet} per hit — vendor extras such as answer, score and raw_content never enter the context. Five interchangeable backends (Tavily, Brave, SearXNG, Google CSE, Exa) with automatic failover to the next usable one in fallback / chain order when the primary fails, deduplicating repeated providers. Returned URLs and snippets are sanitized of tracking parameters.

DeepSeek Harness 的模型fallback链插件：以更智能、更人性化的方式配置fallback链。当主模型撞限流、额度耗尽，或者5xx超时的时候自动向下改派模型，回合不中断。设置页可视化编排：拖拽排序、按计费或者上下文窗口排序候选模型、失败模型自动冷却、管理多条链的停用和启用。零依赖、无构建步骤、默认不介入任何请求。

Compaction backend that replaces the default compaction-basic: it summarizes the conversation with a configurable pool of low-cost models, sizes each chunk to the chosen model's context window, and merges all digests in one call, with per-route cooldown and session-model fallback.
