Plugins

DeepSeek Harness (DSH) plugin: an Overview tab beside Chat/Trajectory plus a right-sidebar page summarizing session progress (goal, todos, key steps), artifacts, and references, with per-turn scoping, OpenViking memory preview, and quick-nav linkage.

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.

Gives the agent 14 tools to create and edit DingTalk Yida apps (apps, forms, pages, schema, data) through the OpenYida CLI, plus a right-sidebar workbench that opens them in the built-in browser.

Tree-style questioning for DSH: click "Ask in tree" on a selection to add a node to the right-sidebar tree and ask inline under it; clicking another node makes it the current parent, so later selections nest there, Alt+click opens a root node, Ctrl+click appends another passage to the same node, double-click jumps back to the quoted text, a red/green dot marks each node as understood or not, and the panel switches between a list view and a horizontal branch graph. "Add to composer" instead puts the quote into the input box as a reference chip, without creating a node. Nodes live in localStorage and nothing is injected into the prompt.

Shares one right-sidebar across every conversation in the same workspace, so you don't have to reopen it when creating or switching conversations, with a switch in Settings → General.

Open STL meshes in the right-Sidebar document preview: browser-side binary/ASCII parsing, a WebGL viewport, and size/volume/surface-area/watertightness statistics.

Play video and audio in the right-Sidebar document preview, streamed over an authenticated HTTP Range route with desktop seek.

Open .blend files in the right-Sidebar document preview: cached Blender headless GLB export plus a dependency-free WebGL viewport and scene statistics. Requires Blender 3.6 or later installed locally.

Meta's Muse Code CLI inside DSH: a composer switch starts muse serve, a right-sidebar panel and five chat tools (muse_open, muse_prompt, muse_read, muse_status, muse_interrupt) share one Muse session, approvals are decided only in the panel, and a local spend guard hard-stops at $10 by default. Windows only; needs the Muse Code CLI installed and signed in. The $10 cap is a local estimate for the muse serve this plugin starts.

Plain-language trust dashboard for the dsh trust family: aggregates the nine channels (injection interception, write denials, egress blocks, custody-chain verification, tool-surface and prompt drift, leftover scans, forgotten compaction constraints, profile composition) into one right-sidebar panel with a single status light and event cards that translate engine jargon into sentences a non-security user can act on; the read and egress engines run from the package's own npm dependencies so those channels work even without the sibling plugins, and absent plugins simply show as not installed.

Sorts every loaded skill into one or more user-owned workspaces in a right-sidebar tab: each workspace is its own category list plus where every skill sits, categories are created, renamed, reordered and deleted in place, and skills are dragged or picked between them. A first run can let the profile model build the first classification, or place skills into categories the user built first; clicking a row copies its /skill-name and hovering unfolds the description the skill ships.

Session-scoped checklists the agent maintains, with a tree per session, a token-budgeted prompt digest and a right-sidebar tab where item titles can be edited.

Task details sidebar for DeepSeek Harness: a "View task details" button under every finished turn opens a resizable right-sidebar panel showing that task's input files, intermediate artifacts, output files, tools and skills used, inferred languages, a step-by-step flow timeline, and the model provider with token usage and cache hit rate.

Right-Sidebar tab menu enhancement for DeepSeek Harness: adds a 'Close other tabs' item that closes every content tab of the session except the one whose menu is open and the docked guide.

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.

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.

Opens STL meshes in the right-Sidebar document preview: binary/ASCII parsing in the browser, a WebGL viewport, and size, volume, surface-area and watertightness statistics.

Opens .blend files in the right-Sidebar document preview: Blender headless exports a cached GLB with scene statistics, rendered by a dependency-free WebGL viewport. Requires Blender 3.6+ on PATH (or set blenderPath).

Adds a four-pointed-star button left of the composer's model selector that rewrites the unsent draft in place — grammar, wording, punctuation and execution order — preserving code, commands, paths, identifiers, numbers and URLs byte-for-byte, answering nothing and never overwriting text typed while it runs. A pencil under every user message reopens that message for editing without touching the draft; because the Harness session log is append-only, an edit forks the conversation before that message rather than rewriting it. A circular restart icon under every reply asks that one question again in a fresh conversation that carries none of the earlier turns. Both are refused while a turn is still answering, and disabled when the reply used a tool that can leave a trace or when the files the message named have since changed. A right-sidebar memory tree draws the conversation as turns, showing what was actually asked and answered, every answer to one question on its own line labelled original, edited or memory-free, newest first, with arrows that re-read an answer in place; right-clicking jumps to a branch or removes it from the plugin's own history.

In-place Markdown editing for the right-sidebar document preview: a file keeps the shipped renderer's look, clicking a paragraph, heading, list, fence, or table cell puts the caret exactly where you clicked, and only the edited range is written back through ctx.fs.writeText, optionally guarded by the version it read.

A right-sidebar session panel that lists every Skill, MCP tool call and file read or write by turn and step, with per-failure error detail.

A browser that lives inside the DSH host: every session gets its own tab, the AI drives it with lazily published browser_embedded_* tools, and a human watches or takes over that same tab in an on-demand right-Sidebar tab — no GUI, no external browser, log

Enhances the native right-sidebar Files tab rather than replacing it: each row gets an @ reference button that inserts the canonical path mention into the composer, plus a size column, a sortable modification-time column, and a status dot for untracked, unstaged and staged files. Below the tree a git bar shows the branch with ahead/behind counts and expands upward into the 20 most recent commits, with a repository selector when a workspace has independent repositories in subdirectories. A header search box walks the workspace recursively and can open a result or expand the tree at it, preview tabs offer reveal-in-tree and one-click @, the tree is keyboard navigable with ARIA tree semantics, and a right-click entry on the Files tab switches back to the native tree at runtime.

SDD task progress (todos) and progress ledger (sdd/progress.md) as a right-sidebar tab bound to the current session, rendered with the official MarkdownText, auto-refresh every 5s.
