Plugins

Chrome and Edge browser control that drives the real logged-in profile, tabs and cookies through an MV3 extension and a loopback Bridge, exposing browser_* tools, a Skill and /chrome commands.

Website cloning methodology skill: a real-source-first decision tree covering static sites, React/Vue/Next content sites and WebGL/Canvas-heavy fronts, mandatory verification of executable code quoted from second-hand AI analyses, and 13 zero-dependency Node scripts for CDP browser recon, asset/font harvesting, route crawling, sourcemap hunting and pixel-diff auditing.

Exposes OpenCode Zen free models to DeepSeek Harness with no API key, tracking Zen gateway changes.

Plan-usage pet for the DSH web GUI: a floating skeletal-animated character reports quota in a speech bubble, auto-matching the configured provider (OpenCode Go, Command Code, DeepSeek) to show a plan percentage or an account balance, and falling back to local token stats when the provider API is unavailable; draggable, wheel-scalable (90-260px), synthesized click sounds, loopback-only routes.

Multi-agent orchestration agent preset for DeepSeek Harness: one chief orchestrator that never implements itself — it triages every request, has a PM expert plan the work, and delegates implementation to domain experts via a merged expert roster (list and summon tools), scheduling parallel work through a dependency-DAG taskboard and a file-based message bus, with delivery gated by an independent review. Ships 11 core experts; more expert teams (Agency agents EN/ZH, classic collections) are one-click downloads from the settings page over dual GitHub/CDN channels with sha256 verification. Published on npm as dsh-expert-orchestrator (requires DSH >= 0.1.7-alpha.2).

Ultra-lightweight Moli (Rust headless browser) web-fetch provider for DeepSeek Harness: renders complex SPAs, micro-frontends, and dynamic pages with ~60MB memory.

Zero-dependency static and sandbox smoke detector for DSH plugins: package-structure gates, cordis contract scans, keyless headless smoke, and ecosystem-listing checks.

Sanitizes leaked DeepSeek DSML closing tags from model text streams.

Tripo 3D generation skills driving the tripo-cli through the shell: text-to-3D, image-to-3D, rigging with locomotion clips, decimation and LOD chains, and export to GLB/FBX/OBJ/STL/USDZ/3MF, with headless device login for both China-mainland and international accounts; installable as `tripo-dsh`.

Hot-switches in-process DSH fetch traffic among direct, manual HTTP(S)/SOCKS5 proxy, and ambient system-proxy modes, with no-proxy rules and optional proxy-environment export for newly spawned child processes.

Web search with Exa, Firecrawl, Tavily and Tinyfish, per-session search connection and freshness preferences, and a chat-toolbar selector.

Office document preview, editing, and DOCX generation for DeepSeek Harness, powered by Fylar Office SDK.

Remote development over SSH: pick a directory on a registered machine as the session workspace and the file, shell, bash, and search tools run on the remote host — the agent works there with the same local tools, and no extra model-facing tools are added.

Fills missing context window, max tokens, thinking levels, and image input on custom DSH models from models.dev, and lists unmatched models for manual edits.

A draggable character companion for the DeepSeek Harness web profile with six visual and expression levels, four task modes, current-session chat, public reasoning summaries and browser speech synthesis.

Installs a Web-profile helper that diagnoses and writes MCP config so Codex, Cursor, or Claude Code can spawn dsh --profile codex.

Plugin governance: new/updated plugins stage in a candidate area first, then hot-mount after startup — success promotes, failure auto-disables, repeated failures freeze, one-click safe mode, sidebar diagnostics panel (npm: `bsfeng-dsh-guardian`).

Browser notifications and a beep when a session turn ends, the agent asks a question or approval is pending; clicking the notification jumps to the session; remote trigger endpoint and SSE channel (npm: `bsfeng-dsh-notify`).

Markdown conversation theme plugin — 4 built-in themes with light and dark variants, user-editable CSS themes, system-aware auto-switching, an in-browser editor with syntax highlighting and save-time validation, and a theme selection that persists across reloads and tabs. Also ships a version-history panel. Windows and DSH Desktop supported.

Read-only trajectory review in a resizable conversation sidebar, with rule analysis, optional model explanations, evidence navigation, and same-range run comparison.

Renders image, video, and audio paths and URLs from DSH conversations inline, with workspace-confined local reads and an optional ComfyUI proxy.

Math Agent Framework for DeepSeek Harness: symbolic derivation engine (CES / quadratic forms / ODE / PDE), SymPy verification, Lean 4 compiler-verified formal proofs, and QED-style multi-agent adversarial verification, exposed as native DSH tools through a TS shell bridging a Python engine. Requires cloning the math-agent-framework repo and `pip install -r requirements.txt`, with MATH_AGENT_HOME pointing at the repo root. Every result carries provenance (engine versions, seed, tolerances) and is marked untrusted data.

Image previews for DSH sessions: read_image thumbnails plus user, assistant, Markdown and present images in a lightbox with zoom, rotate, pan, download, sidebar and native file actions.
