Visual setup and architecture guide for Huashu Design

01 // How It Works & Runtime Architecture

By leveraging Python SDK / OpenAI API, the application isolates runtime dependencies while maintaining low-latency execution traces across multi-step LLM operations.

Deterministic Execution Pipeline Local Stdio Protocol
AI Client (Claude / Cursor)

Sanitized Agent Memory

02 // Real-World Workflows & Use Cases

01

Deterministic AST code analysis, symbol indexing, and cross-file reference discovery

02

Autonomous test generation, test execution feedback loops, and automated patch creation

03

Safe repository refactoring and automated codebase modernization without context leakage

03 // Prerequisites & Compatibility

✓
Runtime Environment
Python 3.10+ installed and available in system PATH
✓
Compatible Client
Claude Desktop, Cursor, Windsurf, Claude Code CLI, or OpenCode
✓
Directory Permissions
Explicit filesystem read/write access to designated directories
✓
License Compliance
Verified permissive MIT open-source license

04 // Client Configuration (claude_desktop_config.json) 

{
  "mcpServers": {
    "huashu-design": {
      "command": "python",
      "args": [
        "-m",
        "huashu_design"
      ]
    }
  }
}

Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).

05 // Step-by-Step Installation

Verified Process
  1. 1

    Clone alchaincyf/huashu-design from GitHub

  2. 2

    Install dependencies with pip install -r requirements.txt (or uv sync)

  3. 3

    Copy .env.example to .env and add your API keys

  4. 4

    Run the skill server and connect your AI client via stdio or HTTP

06 // Execution Boundaries & Security Safeguards

● Context Protection

Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.

● Directory Allowlisting

Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.

● Process Isolation

Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.

07 // Frequently Asked Questions

FAQ Schema Included

What is Huashu Design and how does it empower AI agents?

Huashu Design is an open-source coding capability designed for AI clients and autonomous agents. Huashu Design 3.0 · 在 agent 里打一句话，拿回能交付的设计：网页 / App 原型 / 可编辑 PPTX / 动画 / 信息图 · 六个候选挑三个方向 · 84 种带样张的风格库 · 越用越懂你的外观账本与设计体检 · HTML-native design skill for Claude Code, Codex, Cursor & any agent.

How do I install and configure Huashu Design?

Follow the step-by-step installation: 1) Verify your runtime (Python 3.10+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.

Which AI clients and developer harnesses support Huashu Design?

Huashu Design is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.

What security boundaries and sandboxing safeguards does Huashu Design enforce?

Huashu Design executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.

Is Huashu Design free and open source?

Yes, Huashu Design is published under the MIT open-source license. You can inspect the source code and contribute on GitHub at https://github.com/alchaincyf/huashu-design.
