Claude Code Prompt Engineer

# Claude Code Prompt Engineer MCP Server An advanced Model Context Protocol (MCP) server that intelligently engineers and optimizes prompts for Claude Code, with interactive refinement capabilities and automatic optimization. ## Features ### 🚀 **Intelligent Prompt Engineering** - Automatically detects programming language and task type - Optimizes prompts specifically for Claude Code's capabilities - Leverages knowledge of Claude Code's tools and workflows ### 🤖 **Interactive Refinement** - Q&A-based prompt clarification system - Context-aware question generation - Session-based refinement process ### ⚡ **Automatic Optimization** - Language-specific prompt enhancement - Task complexity detection - Claude Code capability awareness - **No external API dependencies** - works entirely with built-in capabilities ## Installation & Setup ### 1. Install Dependencies ```bash npm install ``` ### 2. Configure Claude Code Create or update your `.mcp.json` configuration file: ```json { "mcpServers": { "prompt-engineer": { "command": "node", "args": ["/absolute/path/to/cc_peng_mcp/index.ts"], "env": {} } } } ``` ### 3. Restart Claude Code ```bash # Exit current session and start new one claude ``` ### 4. Verify Installation ```bash /mcp ``` You should see `prompt-engineer` listed as connected. ## Usage with Claude Code ### 🎯 **Auto-Optimization (Primary Usage)** Simply use the tools directly - no setup required: ``` Use the auto_optimize tool to analyze: "fix my React app performance issues" ``` ### **Interactive Mode for Complex Requests** ``` Use the engineer_prompt tool with interactive=true for: "create a new authentication system" ``` ### **Direct Prompt Engineering** ``` Use the engineer_prompt tool with prompt="optimize my database queries" and language="python" ``` ## Available Tools ### `auto_optimize` ⭐ **Primary Tool** Automatically detects and optimizes natural language text: - `text` (required): Your natural language text/request - `context` (optional): Additional project context - `interactive` (optional): Force interactive questioning ### `engineer_prompt` Manual prompt engineering with specific parameters: - `prompt` (required): The raw user prompt that needs engineering - `language` (optional): Programming language (auto-detected if not provided) - `context` (optional): Additional project context - `interactive` (optional): Enable Q&A refinement process ### `answer_questions` Used to provide answers during interactive sessions: - `sessionId` (required): Session ID from interactive mode - `answers` (required): Array of answers to the questions ## How It Works ### 1. **Natural Language Detection** The system automatically identifies when your text is natural language that needs optimization by detecting: - **Request patterns**: "help me", "can you", "i need", "i want" - **Problem descriptions**: "issue", "bug", "not working", "broken" - **Task indicators**: "create", "build", "fix", "optimize" - **Questions**: "how do", "what is", "why is" - **Conversational markers**: "i'm", "i think", "not sure" ### 2. **Built-in Intelligence** - **No API calls required** - uses pattern matching and rule-based optimization - **Language detection** via regex patterns for 10+ programming languages - **Task type detection** (debug, test, refactor, explain, architecture) - **Complexity analysis** based on text length and technical indicators ### 3. **Claude Code Optimization** Prompts are optimized knowing Claude Code's capabilities: - File system operations (Read, Write, Edit) - Code search (Grep, Glob patterns) - Git operations and workflow management - Todo list management for complex tasks - Browser automation via Playwright MCP - GitHub integration ### 4. **Interactive Refinement** When needed, the system: - Generates clarifying questions based on your prompt - Creates a session to track the conversation - Refines the prompt based on your answers - Delivers a highly optimized final prompt ## Example Workflows ### 🎯 **Auto-Optimization Example** **Input:** ``` "my website is slow and users are complaining" ``` **Auto-Optimized Output:** ``` **Task:** Debug and fix the following issue: my website is slow and users are complaining **Requirements:** - Use file search tools (Grep/Glob) to locate relevant code - Read and analyze the problematic files - Identify the root cause and implement a fix - Test the solution if possible **Ready to proceed with this task?** ``` ### 🤖 **Interactive Mode Example** **Input:** "make my app better" **Questions Generated:** 1. What specific aspect needs improvement (performance, readability, maintainability)? 2. What technology stack or programming language are you using? 3. Are there any constraints or requirements I should know about? **After Answers:** Creates detailed, structured prompt with your specific requirements. ## Benefits ✅ **No Setup Required**: Works immediately after MCP configuration ✅ **No API Keys**: Uses only built-in Claude Code capabilities ✅ **Context Aware**: Understands your project and requirements ✅ **Interactive**: Asks clarifying questions when needed ✅ **Systematic**: Structures complex requests properly ✅ **Fast**: No external API calls for instant optimization ## Requirements - Node.js 16+ - TypeScript support (tsx recommended) - Claude Code CLI - **No external API keys required** ## Technical Details ### Supported Languages - JavaScript/Node.js, TypeScript, Python, Java, C++, Rust, Go, PHP, Ruby, C#/.NET ### Task Types - **Debug**: Bug fixing and error resolution - **Test**: Unit testing and test creation - **Refactor**: Code improvement and restructuring - **Explain**: Code explanation and documentation - **Architecture**: System design and patterns - **Code**: General coding tasks (default) ### Architecture - **Pure pattern matching** - no machine learning models - **Rule-based optimization** - deterministic and fast - **Session management** - for interactive conversations - **Built-in language detection** - regex-based patterns ## License MIT License - feel free to modify and distribute. ## Installation Guide See [INSTALL.md](INSTALL.md) for detailed installation instructions, troubleshooting, and advanced configuration options.
