Plugins

Markdown display enhancements for the DSH Web chat, applied on top of the host renderer rather than replacing it: code blocks become cards with a language label and icon-only wrap and copy buttons, long code blocks, tables and Mermaid diagrams fold behind an expand control, Mermaid fences render as SVG with a diagram and code toggle, a fullscreen viewer with wheel zoom, drag and double-click to fit, and SVG or PNG export, tables get a sticky header and CSV or Markdown copy buttons, and a settings panel adjusts the diagram palette, code font size, the default diagram view and the three fold thresholds.

Action cards: the agent proposes a concrete action (create a file, edit a value, run a command), you edit it and apply it in one click, and the Host executes it and reports back.

DeepSeek Harness (DSH) plugin — connects DSH to MATLAB and Simulink through the official MathWorks MATLAB MCP Server, injects MATLAB/Simulink Agentic Toolkit skills, and provisions everything with one click.

DeepSeek Harness conversation polish: message and step folding, composer and sidebar sizing, folded-content search, turn timing, and confirmed local conversation history deletion.

Devin CLI inside DeepSeek Harness: a `devin` delegation tool, a /devin command, and a `devin` LLM provider route — all over the ctx.subprocess seam.

Adds a Restart card to the harness settings: one click hands the restart to the DeepSeek Harness launcher (`Launch-DeepSeekHarness.ps1`), which replaces the running web process, and the page reconnects itself once the new instance answers. Windows only; without that launcher the button reports an error instead of restarting.

The composer predicts what you are about to type. Inline ghost text sits on the caret, measured against the editor's own font and line box, and Tab turns it into real text (Esc ignores it). The prediction is one short call through the session's own model router, seeded with your draft and the last few turns of the conversation, so an empty composer also gets a next-prompt guess written in the user's voice; suggestions that merely restate the assistant are dropped. Host side is one HTTP route with sub-path endpoints (loopback-only, 64 KB body cap, 2-minute result cache, 20-second miss cache, one in-flight call per session); client side is one 0-height overlay registered on conversation.input.overlay, with insertion guarded by the composer's draftRev CAS and a setDraft fallback. IME composition and slash commands are skipped. 16 node:test cases, zero runtime dependencies, real screenshots in docs/.

A simplified version of the Plan/Act feature in the RooCode and Cline VS Code extensions, binding one provider, model and reasoning effort to plan mode and another to act mode, with per-workspace overrides.

Adds an AIignore tab to the right sidebar: scores the open conversation and its folder across five dimensions, blocks reads of build output, lockfiles and logs before they reach the model, and writes the .aiignore rules for them one button at a time.

Session board in the left sidebar: every chat session's current work, todos and progress, with a searchable overview heatmap and one-click navigation back to the session.

Polish button in the composer that rewrites the draft with the model the current conversation already uses: four styles, a fidelity guard that keeps every concrete fact verbatim, one-click revert, and no API key of its own.

Folders for the DSH Plugins page: group installed plugins, toggle a whole group, batch move with undo, search across groups, long-press drag to reorder, reinstall removed plugins from their record, and restart Harness with one click.

AI Book Shelf: read EPUB, PDF, TXT, Markdown, HTML, FB2 and DOCX; select text for one-click background and explanations, then follow up without leaving the page; full-book search, online book search and custom sources; paper mode with translation, bilingu

Code-generated math and science animation for DSH: six tools cover environment checks and dependency self-repair, Manim/manimgx scene rendering to storyboard frames or MP4, contact-sheet probing of finished clips for black or overexposed frames, and formula identity checks with SymPy, together with three skills (topic routing, design spec, QA rubric), a project scaffold with timeline and narration, requirement approvals before rendering, and five animation styles.

DSH-Search-Contrl: a DSH skill/plugin for scoped web search and Chinese daily reports, with a settings GUI for custom search sources, arbitrary topics (not only tech), creator-link scoped search, and one-click rollback.

Turns a phone into a personal assistant for the DeepSeek Harness on your computer — pair once by QR code, then chat, send photos and files, watch replies stream, and collaborate from several phones at once over LAN, Tailscale or a public tunnel. Ships an Android app, an iOS build pipeline and a zero-install web/PWA client for HarmonyOS and iOS browsers.

For DSH plugin AUTHORS: run this after you finish writing a plugin and it audits the entire publish path, then hands you the exact GitHub + npm + market commands. Pre-publish gate for DSH plugins. Turns every silent failure in the publish path into a deterministic check: package.json completeness (missing exports\["."], files omitting lib/ so the tarball is empty, no "type": "module", client declared without a ./client export), UTF-8 BOM, JSON/YAML parse errors, cordis.patch.yml insert rows written at the wrong indent (the bug that makes a plugin install and never mount), insert name mismatches, missing entry exports, require() inside ESM, missing LICENSE or README install line, missing tests, unscoped npm names that return a 403 no granular token can diagnose, versions already on the registry, and missing GitHub repos. Six agent tools; every finding carries its fix. Read-only, no LLM.

Mobile-viewport preview tab for the right sidebar, with nine preset sizes covering phones, tablets and a laptop plus a custom width/height, one-click URL copy, and the page URL inserted into the composer through an @ button or the /url command.

Reads your past DSH conversations and surfaces recurring prompt gaps — missing paths or versions, an unstated output format, missing preconditions that break tool calls — each with a paste-ready rewrite. Adds a one-click rewrite next to the composer that applies those constraints to the draft in a shorter form.

Adds Meta's Muse Code subscription as a DSH model provider: the bundle declares the shipped Meta route under Settings > Models, syncs the account chat catalog (Muse Wonder included) into the model picker, and adds a Sign in card plus the /muse-login command that run DSH's built-in Meta device-code flow, keep the minted key renewed, and show a red or green credential dot. Needs an active Muse Code subscription and no Meta CLI.

Per-turn and per-step cost ledger for DeepSeek Harness: a Turns tab beside Chat and Trajectory with tokens, estimated cost, cache savings, and an inspector for tool arguments, raw results, and source. Client-only; prices are estimated from recorded model usage.

Split the DSH sidebar workspace list into Active, Session tasks and Inactive sections with manual pins and an activity threshold, keeping the official search, archive filters, row menus and drag and drop, with a one-click switch back to the shipped list. The Session tasks section uses a fixed Windows workspace at D:\files\history-tasks; other platforms must create that directory manually.

Opens chat.deepseek.com inside DSH Desktop from a conversation view tab (next to Chat / Trajectory / Context, scoped to the open conversation) and from a left-rail globe button — all entries share one embedded page, so switching between them never reloads it. Keeps you signed in across restarts by replaying a localStorage plus readable-cookie snapshot before the page's own scripts run, strips only the Electron/<version> token from the user agent, and keeps navigation inside deepseek.com while sending everything else to the system browser. Pure client code: no host-side script, no file access, no credential service, no server route.

rulemux rules inside DeepSeek Harness (dsh): asks the rulemux CLI for the rules it renders for this workspace and injects them into the session once, on the first turn (nothing written to disk for rules). Also syncs skills into the native skills dirs (.ds
