Tools & Capabilities

HeartFlow (心虫) AGI layer-1 discriminator gate as a DSH plugin: 47-dimension rule-based text checking (heartflow_check tool) plus automatic output supervision at tools/post-execute, fail-closed when engine missing.

DSV4.1 reasoning support with multimodal context and bounded artifact acceptance for DeepSeek Harness

Runs the built-in web_search tool server-side on an OpenRouter-compatible gateway, so search uses the same endpoint and key as the chat models: three request protocols, every citation shape parsed (including snippets recovered from the cited span), and a settings card with a live connection test.

Mounts Microsoft's Playwright MCP through the official dsh-mcp-client, so the agent gets Playwright MCP's own browser tools over stdio and can attach over CDP to a browser you are already signed in to.

Universal Model Context Protocol (MCP) bridge for DeepSeek Harness: connects agents to stdio/sse/websocket MCP servers with a 10k dormant scale engine, sub-millisecond BM25 tool search, dynamic token budgeting, and a real-time web UI dashboard.

TypeSafe Jev (System One decision model) for DeepSeek Harness, end to end: jev_decision (choice/score/noul, parallel, typed answers + confidence), a Settings > Plugins card for the API key and switches, inline tool views showing every decision in the conversation (answer, confidence, latency, cost), an auto-guard (deterministic + Jev risk/loop checks), a local /jev dashboard, and an online verification benchmark (96.3% on 27 labeled questions, median ~283 ms on jev-latest, 2026-09-21). Honest by design: real API only, no mock fallback.

Business knowledge-network context for DeepSeek Harness: bind a session to an OpenBKN knowledge network, query its objects and metrics through managed MCP tools, and open trace-backed provenance (execution facts and a business graph) for each answer. Ships with the OpenBKN Runtime; the provenance views need an OpenBKN enterprise license.

AST-based structural code search and syntax outline tool powered by ast-grep.

LSP action surface for DeepSeek Harness providing diagnostics, formatting, rename, code actions, and symbols over real language servers.

模型可见的远程文件工具 read_remote、write_remote、edit_remote，经 ssh 读写远程主机文件。write_remote 只允许新建，绝无覆写分支；文件后端 RemoteFileSystem 不继承 FileSystem，仅借用 @deepseek-ai/dsh-fs 的类型词表与 FsError。标准可安装的 dsh host 插件。

Tavily-backed search provider for the DeepSeek Harness web capability seam (ctx.web) — replaces the official web search with multi-key balance-aware rotation, manageable from the DSH web settings (Plugins → Plugin configuration).

Cloud workspaces for DeepSeek Harness: pick "Cloud (SSH)" in the workspace chooser and the agent's bash/read/write/edit/glob/grep tools transparently run on your Linux server over SSH. Includes ssh_* agent tools, an SSH host settings card, jump-host suppo

Workspace drift awareness for DeepSeek Harness agents: detects external/user file changes and injects them into the agent context at step boundaries.

Per-project runtime environments for DeepSeek Harness: auto-adopt or create a project-local Python venv (.venv_local/python) and wire in the toolchains and env vars for the runtimes each project uses (python venv / node / go) — python & pip always resolve to the project, never silently to system Python.

AI form filling and spreadsheet autofill for XLSX in DeepSeek Harness, using authorized Qichacha MCP facts with cell previews, user confirmation and export to a new copy.

TickTick (Dida365) task bridge: a session-header task panel and curated agent tools over the official TickTick MCP endpoint.

Routes the DSH web_search tool through Ollama's web search API, reusing OLLAMA_API_KEY. No DeepSeek official key needed.
