Tools & Capabilities

A self-healing layer for tool calls: missing params, wrong fields and out-of-range paths are fixed before they reach the model. Measured visible error rate fell from 7.95% to 2.20%.

FormatForge: forge 30+ file formats (PDF, DOCX, PPTX, XLSX, EML, EPUB, TOML, archives) into AI-readable text via a drag-and-drop inbox, ff_translate/ff_formats/ff_result tools and a CLI; scanned PDFs fall back to local OCR or an enhance hint for the session model.

Playwright/CDP web-fetch provider for the built-in web_fetch tool: renders pages in a real browser, denoises them (Readability + DOMPurify) and returns markdown.

Content-aware tool-result reducer: 13 reducers cut oversized output by meaning at tools/post-execute (failing tests kept, diff context dropped, JSON and CSV sampled, lint problems grouped by rule, dependency stack frames collapsed, crowded directories counted), with full originals spilled to disk behind a locator.

Learning Mode agent preset: a coding agent that teaches while coding — concrete scenario-grounded explanations, Socratic guidance, and TODO(你) practice blanks, modeled on Claude Code's Learning output style; installable via dsh plugin add (dsh-learning-mode on npm).

Installs the browser4-cli runtime and registers the Browser4 skills (browser4-cli, browser4-experience, browser4-plugin, scent-miner) into the DSH skill registry, providing an AI-native browser engine for autonomous agents, intelligent extraction, and large-scale web automation.

AI-driven drawio: four agent tools (validate, render to SVG/PNG, edit, template) plus a sidebar live board — zero-dependency mxfile-to-SVG preview, embedded diagrams.net editor with save bridge, and auto-open whenever the agent draws.

Parse PDFs and documents into structured Markdown with MinerU. Uploads files to the MinerU cloud; no offline mode.

Local PDF, Office, image, and OCR document intelligence for DeepSeek Harness.

Batch-port official Codex plugins into DSH skills (codex_list/port/status/health; measured: 186 plugins / 583 skills, 577 ported, 0 failures).

MCP hub for 1C development: keeps 1C:EDT connected through EDT-MCP, starts BSL Language Server with workspace roots on demand, and adds per-project settings, a read-only documentation wiki, model rules and SonarQube/GitLab skills. Requires 1C:EDT 2026.1/2026.2 with EDT-MCP running (default 127.0.0.1:8765).

Registers the minas-webdav MCP server as one stdio row, giving the agent 14 tools for a Xiaomi Smart Storage (MINAS) NAS without mounting it: list, stat, tree, find, du, df, cat, upload, download, mkdir, move, copy, delete and a capability probe. The Python package behind it is installed separately with pipx.

Switchable backends behind the native web_search and web_fetch, chosen per session from a composer menu or /setup-search and /setup-fetch: DeepSeek, Exa, Firecrawl, Tavily, Tinyfish, OpenAlex, Semantic Scholar and server-side model search for search; local HTTP with a private-network allowlist, the DeepSeek Fetch API, Exa, Firecrawl, Tavily and Tinyfish for fetch.

Pinned-version REA for DeepSeek Harness: installs rea-agents locally, starts its MCP server from that pinned copy, and upgrades only when you press Update.

Routes model requests, web fetches/searches and spawned tools through the Windows system proxy or a custom address — idempotent kernel (reads never rebuild the dispatcher), header one-click toggle, per-URL route diagnosis and NTLM-aware 407 hints.

Tool-call discipline for DeepSeek Harness with behavior prompts, failure-driven concurrency reduction and retry guidance, post-write checks with backup rollback, high-risk command gates, change summaries and verification reminders, advisory project-memory checks, configurable project-discipline reminders after compaction or at intervals, and compliance statistics.

Local code intelligence for DSH: Impact X-Ray visualizes potential change impact with inspectable source evidence and uncertainty; also provides symbol navigation, bounded Context Packs and ArkTS support.

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.

Drives a real Chrome through a local MCP server so the agent can search Google/Bing/Sogou, read any page including JS-rendered and login-only content, automate click/scroll/type/key-press/select in a background window, and run platform search/detail/comment/download for Zhihu, Xiaohongshu, Douyin, Bilibili, X and Reddit; resumable comments, SHA-256-verified downloads, cookies never returned, localhost only.

Windows-only Computer Use plugin for DeepSeek Harness with UIA, cua-driver, and optional GLM vision.

Aggregated web search provider that fans one query out to 11 engines (Exa, Parallel, DuckDuckGo, SearXNG, Brave, Tavily, Serper, Mojeek, DeepSeek, Anthropic, OpenAI) concurrently, URL-dedupes and merges the results. Ships a settings card for toggling backends, storing API keys in the credential store, and tuning concurrency and timeouts.

Agent preset for DeepSeek Harness that layers the self-referential Cordis toolset (dynamic plugins, runtime inspection) and preset-authoring skills onto the PTC Code-Mode preset; materialized files carry per-file sha256 markers, so user-edited presets are never overwritten on upgrade or uninstall.

Cordis /hongtou command: two-phase pipeline (LLM structured JSON + deterministic Word 2003 XML template rendering)

AI interview practice for DeepSeek Harness Web: generates questions across four modes (concept review, mock interview, scenario, LeetCode Hot 100), scores answers, and provides explanations.
