Plugins

One-click restart for the DSH desktop client, from five entries you can toggle individually: a sidebar panel, the sidebar footer, the conversation header, a Settings → General row, or the /restart slash command. The app is closed gracefully (only the main process is signalled, so the host can flush session logs) and relaunched by a detached helper that survives the shutdown; optional guards wait for running tasks or an in-progress plugin install, results land in a receipt, requests are fenced to loopback same-origin, and every switch is persisted in the profile config file. Only the four UI entries can be switched off; the slash command is always available.

A governed registry for MCP connectors (stdio and streamable-http): four-level fail-closed authorization, mcpServers JSON import that rejects malformed args, credential redaction at every output boundary, an agent bridge that returns an honest review verdict instead of a fake approval, and a /mcp-reg operator console plus a settings page.

DSH hardware sandbox plugin: assemble a 3D scene of ESP32 / BME280 / PIR / LED components with protocol- and voltage-checked port wiring, run real Python project code in the loop against simulated I2C/GPIO hardware with fault injection, let networked device simulators report over HTTP to a real backend (validated end-to-end against a live seat-reservation system), observe a real device read-only and map its state onto the scene, and add support for new boards through data-driven pin definitions. Ships 16 hw_* agent tools plus a bundled SKILL.md.

Safe, resumable automation and analysis tools for CST Studio Suite, with task planning, solve-budget control, persistent runs, result extraction, far-field analysis, and parameter sweeps.

A daily journal the agent keeps: the journal_record tool appends dated todos and memories, with optional detail and tags, to one JSON file per day under the DSH home; the right sidebar draws those files as a month calendar marked per day by open todos, finished todos or memories, with checkable todos and the selected day's entries below; and the duty sentence it adds to the system prompt is editable from the calendar itself.

Model picker dialog with routing groups: a model that keeps failing hands the turn to the next usable model in its group, and the dialog also carries a metrics dashboard and a free-channel tab. That tab installs six channel plugins — Our Free Model (the only one that needs no login or API key), CodeArts, WorkBuddy, Trae, Qoder and Providers Hub — whose providers cover 23 platforms: Huawei Cloud CodeArts, Tencent CodeBuddy, WorkBuddy, Youdao LobsterAI, Qoder, TRAE, Cline, iFlytek Loomy, SenseTime Raccoon, MiniMax, Zhipu ZCode, Gemini Code Assist, Alibaba Accio, iFlytek AStudio, OpenCode, OfficeAce, AutoClaw, ModelScope, Qiniu, Codely, MonkeyCode, Baizhi Cloud and MagiCrew.

Runs a local OpenAI-compatible gateway so DSH can use the model quota of a logged-in Tencent CodeBuddy (WorkBuddy) account: one-shot installer with SHA256 verification, logon scheduled task with duplicate-launch guard, manage.ps1 for status/start/stop/restart/logs/update/uninstall, and an agent skill that drives setup and troubleshooting.

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).

A configurable Liquid Glass theme for DeepSeek Harness with translucent surfaces, wallpaper, desktop transparency, window blur, custom cursors, click ripples, and per-side conversation contrast controls.

Full-screen video boot splash — play an mp4 at startup, skip with a click, import your own clip, and non-playable codecs are transcoded to H.264 automatically.

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.

Local TXT novel reader in the DSH right sidebar: bookshelf with file, directory and path import, chapter table of contents with jump, click-to-turn or vertical-scroll paging, reading progress restored across restarts, and font, line-spacing, background and night themes.

System-level desktop floating-window plugin for DeepSeek Harness (DSH): a global hotkey opens a floating window; the plugin supports workspace and session switching, approval and follow-up handling, and export of its own diagnostic logs for plugin troubleshooting.

Claude Code-style workbench in DSH: workspace/session sidebar, streaming document-style transcript with unified tool cards and thinking, Markdown and Mermaid rendering, dark theme, and a draggable overlay panel backed by an in-host HTTP/WebSocket service.

Skill manager for DSH with a pack system. Installs skills as versioned packs and never overwrites files you have edited - upgrades skip your changes and report them. Also ships 6 built-in skills, a problem-grouped settings panel, and tools that let the agent read and write the skill library in conversation.

Verifies letters signed by other agents: a canonical field order, digest and HMAC checks, and fail-closed handling of missing or unregistered fields. Off by default; when enabled, a letter that fails any check is refused rather than delivered.

Sounds and notifications when a task completes or waits for your approval or answer; notification sounds are configurable in the settings page (synth styles or your own audio file), with built-in cat hachimi sounds, just for fun. An optional Windows patch adds a taskbar digit, flashing and native toasts.

Makes the built-in web_fetch tool work when Clash / mihomo runs in TUN mode with fake-ip: it lets the fake-ip address ranges (198.18.0.0/15, fdfe:dcba:9876::/64, 2001:2::/48) past the public-address check that otherwise rejects them, while loopback, private and link-local addresses stay blocked as before. Works with no proxy environment variables and no Clash changes.

Trip-planning agent preset for mainland China that answers in Chinese: queries 12306 train availability, Fliggy and Tuniu flight and hotel prices, and real Amap transit routes, checks closures and weather, and delivers a single offline HTML roadbook with draggable maps, three hotel price tiers and an itemized budget. Ships 9 skills, an environment doctor that walks users through missing API keys, and a patch for the 12306 MCP server; it plans and queries but never books or pays.

File-backed post office between DeepSeek Harness sessions: every letter is sealed with an HMAC and a body digest, recipients are resolved through a roster interface, and delivery is offline-first, so an undeliverable letter waits in the mailbox instead of being lost.

A Herta theme for DeepSeek Harness: an ASCII boot opening ported from the upstream Herta project, a violet palette of design tokens, swappable wallpapers (four bundled, plus image URL, local import, solid colour or off) and a "Herta Appearance" page in DSH settings. Doubles as the theme that dsh-herta ships with.

Daily sending quotas and quiet hours for agent mailboxes: letters are counted in named buckets that each carry a per-day limit, the day boundary is configurable, and a quiet window tells the core to hold online letters rather than deliver them.

Sidebar panel for the announcement file and the ticket status table. It lists the announcements together with how many sessions have seen each one, shows the delivery status, and lets the user post, edit and delete entries. Requires the third-party dsh-better-sidebar plugin.

Project-level memory built around a ledger whose structure the AI designs per project; the plugin only handles detection, injection, write-back, archiving and git. Memories are split by meaning: the active ledger holds current state, the turn journal is append-only, and decisions, the goal tree and lessons are one-card-per-file (with a multi-dimension index over the card folders); the fundamental principles file can be changed only by the user. There is a single compaction mode: before compacting, the AI sorts the work into three buckets - what must stay in context and is re-injected verbatim, what is written to the project's _stash/ for later lookup, and what is dropped. When a conversation is opened in a container workspace holding several projects, it can be locked to one sub-project (the lock lives in the plugin's own home and survives restarts; it leaves no marker in your project). Also an activity log with five levels, where L4 stores the user's own words verbatim (never injected, queryable on demand). Before each compaction a verbatim capsule (user quotes, raw errors, changed files) is written to disk, and both the capsule and its source material survive a restart; a handoff document lets a new conversation resume the previous one. 21 tools, 12 subcommands, 39 settings (one of them switches whether the settings panel or each project's manifest wins). Runs locally, no runtime dependencies.
