Tools & Capabilities

Registers a keyless search provider for the built-in web_search tool so it works without an API key, failing over between the documented no-key tiers of Tavily and Firecrawl; a TAVILY_API_KEY or FIRECRAWL_API_KEY is picked up automatically when present. Two Bing scrape backends are included but off by default.

Windows-native computer use for DeepSeek Harness: two tools drive and read any desktop app. One batch call runs find, click, type, key, read, wait and screenshot steps in a single engine pass, so a task whose steps are known up front costs one model round trip; reading returns window text rather than an image, and input and capture prefer UI Automation patterns, Win32 messages and offscreen PrintWindow so the user's focus and pointer stay untouched.

Manage frequently used file bookmarks in DeepSeek Harness, supporting bookmark saving, listing and navigation. It also allows creation of frequently used projects, including management projects, code projects and more.

Semantic tool routing, skill discovery, and typed System One decisions for DeepSeek Harness powered by TypeSafe Jev.

Mounts the mcptoon MCP gateway as one stdio server, so the agent discovers the tools of every MCP server you have configured through mcptoon's compressed view instead of full JSON schemas on each turn. Ships a doctor CLI that checks the mcptoon executable resolves and prints the exact command/args override when it does not.

Cindy 手机客户端连接 DSH 的 Host 侧插件：会话/消息/审批/todo/goal 的手机通道，以及配套的设置卡片

Prompt-polish template injector for DSH: click ✨ in the composer to inject a "polish my prompt" template (current draft auto-embedded), no send, no network, no model — the main agent rewrites with full context. Replaces narrative-prompt-polish (2026-09-14 migration).

Indexes the current workspace into a relation graph and exposes one agent tool, codegraph_explore, for reachability, callers, and impact, plus a Web sidebar graph pane.

Figma design context for the agent: reads a frame's node tree, auto-layout, paints and typography, resolves the variables it is bound to, and renders a screenshot to compare code against — plus four bundled design-to-code skills. Connect with one button against Figma's own consent page; the plugin ships its own OAuth app, refreshes tokens automatically, and never asks for or displays a token.

Appends actionable hints to failed tool results, such as the nearest existing directory when a path does not exist.

Hard stop for runaway turns: blocks repeated identical tool calls and ends the turn when per-turn step or time budgets are exceeded.

End-of-chat visual storyboard: a storyboard tool renders a self-contained HTML card (inline SVG diagram, numbered flow, facts grid, timeline) from a JSON spec, writes it under ~/.dsh/storyboard/<session>/ and opens it in the sidebar; a system-prompt section and a /storyboard command trigger generation. Server-only, zero runtime dependencies.

Consistency guard for long-form writing: scans conversation prose for character, timeline and numeric setting conflicts across chapters, then jumps straight to the conflicting message.

Registers any set of HTTP APIs as paired doc-query and request tools for the agent.

9router-backed web search + fetch providers for DeepSeek Harness (ctx.web). Wires the native web_search/web_fetch tools to 9router's /v1/search and /v1/web/fetch endpoints.

DSH right-sidebar plugin that compares two git commits, builds a manual-test checklist from the impact scope, and supports fail notes, screenshots, task attachments, and defect submission to Yunxiao, GitHub, GitLab, or a webhook.

Dead-loop brake for DSH agent sessions: detects repeated identical tool calls, repeating call sequences, and duplicate text, then reminds the agent or refuses the call before it runs.

Adds configurable HTTP header profiles that can be selected per model.

Controlled browser automation for DeepSeek Harness: the agent_browser tool and BrowserAutomationService drive a real Chromium or Chrome page (or an explicit CDP endpoint) through the agent-browser CLI, with allowedDomains containment and per-call output limits.

Exa-backed web search provider for the ctx.web seam, with Exa Dynamic Highlights on by default and the Exa-Beta header that setting requires; exposes all eight Exa retrieval types, adds an /exa command to change highlights, search type and result count at runtime, and registers an exa_search tool that takes its own result count.

Generates 3Blue1Brown-style Manim animations to explain answers, with a right-column gallery and inline multi-modal file publishing.

Computer Use for macOS desktop applications: reads any app's accessibility tree as text with element indices, then clicks, types, pastes, scrolls, drags, selects text and sets values through it, plus screenshots read back as images. Driven by a persistent JavaScript REPL — the agent gets two tools (`js`, `js_reset`) and calls an `sky` API inside them, so state survives between calls and the tool schema stays fixed as capabilities grow. Accessibility trees come back as diffs after the first read; actions address elements by index and indices from a stale read are refused rather than misapplied; typing waits for keyboard focus and reads the field back; paste restores the clipboard. Requires macOS 14.4+, Accessibility permission (Screen Recording only for screenshots) and Node 20+; ships a prebuilt native module, so nothing compiles at install time.
