Tools & Capabilities

Map and routing tools: driving/transit/walking/bicycling route planning, geocoding and POI search via free OSM/OSRM data by default, with an optional Amap (高德) key for better China coverage.

PDF parsing tools for DSH: pdf_info, pdf_extract_text, and pdf_render_page with dual pdfjs and built-in rendering engines, including system-font rendering for PDFs with non-embedded CJK fonts.

Overleaf-style LaTeX paper workbench: annotate any text in the rendered PDF and let a dsh agent revise the sources with compile checks and git history.

Chinese localization for DeepSeek Harness: translates all system prompts, tool descriptions, and runtime contexts into Chinese at runtime via the system-prompt/assemble waterfall (1788 entries, zero source modification, uninstall restores English).

Database tools for agents: list/query/exec/schema/stats/health across SQLite/MySQL/PostgreSQL, with lexer-grade read-only protection, row caps, CSV/JSON query output and an approval-gated write path.

SearXNG search and Crawl4AI fetch providers for DeepSeek Harness

US stock quotes, price history, financial statements, analyst consensus and news via yahoo-finance2.

Safe math expression evaluator, zero-dependency recursive-descent parser.

Antu diagrams inside DeepSeek Harness: Host tools (antu_validate / antu_layout / antu_render) and an interactive chat card.

Academic tools in TypeScript, no Python or MCP server: the Zotero library through its local API or zotero.org (search, annotations, full text, citation export; add by DOI / arXiv id, notes and tags when writing is turned on), starting Zotero when it is closed; paper search across arXiv, OpenAlex, Crossref, Semantic Scholar, PubMed and Europe PMC, plus CNKI and Google Scholar through a browser window; open-access full text, citations from the DOI registry, reference checking; 11 bundled skills.

Chat-operated multi-database admin plugin for DeepSeek Harness: query and manage MySQL, PostgreSQL, GaussDB, MongoDB, Redis, Oracle, DM and SQLite from the conversation with project-scoped ro/rw grants, a sidebar management panel, schema browsing and data preview, and confirmation-gated dangerous operations.

AX-first macOS computer use for DeepSeek Harness: accessibility snapshots with stable refs, background input, Unicode typing, menus and apps, set-of-mark screenshots, on-device OCR and verified actions — 11 tools bridged to the macos-cu CLI.

Shell tool with four Windows backends (PowerShell / Git Bash / WSL / MSYS2) plus an interactive PTY terminal; the MSYS2 backend starts bash.exe with -lc so /etc/profile puts /usr/bin and /mingw64/bin on PATH, and injects MSYSTEM=MINGW64 into the PTY environment. Written in TypeScript, targets DSH 0.1.2+.

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.

Layered token-optimization pipeline for DeepSeek Harness: output ladder, MCP lazy loading,compaction driver, cache-hit reporting. Built on real DSH plugin APIs; ~40-60% input saved in long sessions.

Adds a subagent_codex tool that delegates tasks to the local OpenAI Codex CLI, running the work in an isolated external process.

Self-contained literature library for DSH with optional Zotero export: full-text PDF fetching (Unpaywall/arXiv/custom URL templates), loose Crossref-backed search, APA/GB-T 7714/MLA/Chicago citation generation, a side-panel PDF reader with highlights and notes, and AI-assisted Q&A/translation steered into the current conversation.

Visible Electron browser for DSH with one shared BrowserWindow, isolated task views, explicit human-Agent handoff, snapshot-reference and native navigation tools, operation trails, demand-driven page thumbnails, keyed session recovery for reliable tab switching and closing, and site-scoped cookie clearing for login maintenance.

Enhances data visualization in DeepSeek Harness by automatically selecting chart types from user input and generating images for trends, comparisons, proportions, relationships, and flows.

Package and install code-server (the web version of VSCode) as a plugin within dsh to quickly achieve professional file editing.

Embedded MCP server letting external agents (Hermes, Claude Code, etc.) drive DeepSeek Harness over StreamableHTTP: sync/async task execution, a three-tier file sandbox, a Web-backed approval bridge, session management and search, and path-jailed file tools.
