Plugins

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.

Bridges the Codebase Memory MCP code knowledge graph into DSH and keeps indexed repositories fresh with a debounced filesystem watcher. Windows-only MCP bridge (the watcher half is cross-platform); auto-installs its npm CLI via npx on first start.

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.

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`).

Modular execution discipline and autonomous steward for DSH: evidence-first routing across 44 canonical skills, durable state planning, verification gates, fail-streak recovery, and interactive web dashboard.

AST-based context compression, test log filtering, and token budget guard for DeepSeek Harness: strips redundant syntax, prunes noisy log lines, and enforces a token ceiling so the context window never overflows.

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.

A-share market dashboard for DeepSeek Harness (DSH): realtime quotes and indices, full-market search, intraday and forward-adjusted candlestick K-line with F10 fundamentals, stock/ETF/convertible-bond/LOF boards, watchlist with position P/L and price alerts, 13-signal screener with 7 preset strategies, limit-up sentiment thermometer, dragon-tiger list, three-source 7x24 news, and AI stock analysis.

Provides the see_image tool for DSH: send an image file to a configurable OpenAI-compatible vision model and relay its description back to a text-only model.

A customizable widget rail for the right side of DeepSeek Harness: 61 cards covering session stats, tokens and cache, context, background jobs, subagents, machine metrics, OpenCode Go and Command Code quota, session cost, peak pricing and the GitHub review queue. Cards install from an in-rail market into 1-4 column grids and 2x2 or 2x4 tiles, with per-instance settings, a magnification wave under the pointer and a one-click hide. Works on DSH 0.1.x and 0.2.x, web UI and desktop app.

Adds a Compact context button and a New session button to the context meter panel; compact submits /compact through the same command channel, and new session starts a fresh session in the same workspace.

Claim-verification skill that checks design documents and plans against codebase facts, escalating behavioral claims to executable logic-primitive verification for state machines and data models, with before/after regression, domain constraints, and concurrency risk mining.

Prompt library above the DSH composer — a 📚 button expands a searchable panel to insert saved prompts into the draft with one click (appends, never overwrites), persisted in a host-side JSON file.

Large-image recognition for vision-exp models: lossless 800×800 tile recognition (smart/pipeline/full), local OCR with preprocessing & handwriting routing, optional multi-vendor GPU (DirectML/CUDA/OpenVINO) with auto CPU fallback.

Free web search for DSH: anonymous Parallel default plus Exa fallback, a Settings toggle, and an MCP server compatible with Claude Code and Codex.

Free web search with 10 engines (Bing/DuckDuckGo/SearXNG/AnySearch free + Exa/Tavily/Keenable/Perplexity/DeepSeek paid), automatic fallback chain, time-filtered advanced search, platform search (GitHub/Reddit), web page fetching, LRU caching, and a settings UI. No API keys required for basic use.
