@cadcamfun/ai-service\n\nAdvanced AI service package with Claude MCP integration, Zustand stores, and React components for CAD/CAM applications.\n\n## āœØ Features\n\n- šŸ¤– **Multi-provider AI support** - Anthropic Claude & OpenAI GPT\n- šŸ” **Secure API key management** - Client-side configuration required\n- šŸŽ›ļø **Zustand state management** - Type-safe stores for React apps\n- āš›ļø **React components & hooks** - Ready-to-use UI components\n- šŸ”§ **TypeScript support** - Full type safety and IntelliSense\n- šŸŒ **MCP integration** - Model Context Protocol support\n- šŸ§  **Memory system** - AI memory with Mem0 integration\n- šŸŽÆ **CAD/CAM specialized** - Purpose-built for engineering applications\n\n## šŸ“¦ Installation\n\n```bash\nnpm install @cadcamfun/ai-service\n# or\nyarn add @cadcamfun/ai-service\n```\n\n### Peer Dependencies\n\n```bash\n# Required for React features\nnpm install react react-dom zustand\n\n# Required for Next.js features\nnpm install next\n\n# Required for icons\nnpm install react-feather\n```\n\n## šŸš€ Quick Start\n\n### 1. React App Setup\n\n```tsx\nimport React from 'react';\nimport { \n AIConfigProvider, \n AIAssistant, \n createQuickConfig \n} from '@cadcamfun/ai-service';\n\nfunction App() {\n return (\n \n
\n

My CAD/CAM App

\n \n {/* AI Assistant with configuration UI */}\n {\n console.log('Generated CAD elements:', elements);\n }}\n showConfigButton={true}\n />\n
\n \n );\n}\n\nexport default App;\n```\n\n### 2. API Key Configuration\n\nThe package requires you to provide your own API keys. Users will see a configuration UI:\n\n```tsx\nimport { APIKeyConfig } from '@cadcamfun/ai-service';\n\n {\n console.log('āœ… AI Service configured');\n }}\n onConfigError={(error) => {\n console.error('āŒ Configuration failed:', error);\n }}\n showAdvanced={true}\n/>\n```\n\n### 3. Programmatic Usage\n\n```tsx\nimport { aiService, aiConfigService } from '@cadcamfun/ai-service';\n\n// Configure the service\naiConfigService.setConfig({\n anthropic: {\n apiKey: 'sk-ant-your-key-here',\n defaultModel: 'claude-sonnet-4-20250514'\n },\n openai: {\n apiKey: 'sk-your-key-here',\n defaultModel: 'gpt-4.1'\n }\n});\n\n// Generate CAD elements from text\nconst result = await aiService.textToCADElements({\n description: 'Create a mechanical bearing with 20mm inner diameter',\n style: 'engineering',\n complexity: 'moderate'\n});\n\nif (result.success) {\n console.log('Generated elements:', result.data);\n}\n```\n\n## šŸ”‘ API Keys Setup\n\n### Get Your API Keys\n\n1. **Anthropic Claude**: Visit [console.anthropic.com](https://console.anthropic.com)\n2. **OpenAI GPT**: Visit [platform.openai.com/api-keys](https://platform.openai.com/api-keys)\n3. **Mem0 (optional)**: Visit [app.mem0.ai](https://app.mem0.ai)\n\n### Security Best Practices\n\nāš ļø **Important**: This package requires client-side API key configuration. For production apps:\n\n1. **Never commit API keys** to version control\n2. **Use environment variables** for development\n3. **Consider server-side API routes** for sensitive operations\n4. **Implement proper API key validation** in your app\n\n## šŸ“š Examples\n\n### Basic React Component\n\n```tsx\nimport { useAIConversation } from '@cadcamfun/ai-service';\n\nfunction ChatComponent() {\n const { messages, sendMessage, isProcessing } = useAIConversation();\n \n const handleSend = async () => {\n await sendMessage('Create a simple cube');\n };\n\n return (\n
\n {messages.map(msg => (\n
{msg.content}
\n ))}\n \n

execution:\n\n```typescript\nimport { batchProcessor } from '@cadcamfun/ai-service';\n\n// Process CAD elements in parallel\nconst result = await batchProcessor.processCADElements(\n cadElements,\n 'optimize', // 'validate' | 'transform' | 'optimize' | 'render'\n { maxConcurrency: 10 }\n);\n\nconsole.log(`Processed: ${result.successful.length}, Failed: ${result.failed.length}`);\n\n// Custom batch processing\nconst customResult = await batchProcessor.processBatch(\n items,\n async (item) => await processItem(item),\n {\n priority: 'high',\n onProgress: (completed, total) => {\n console.log(`Progress: ${completed}/${total}`);\n }\n }\n);\n```\n\n**Features:**\n- **Parallel processing** with concurrency control\n- **Backpressure handling** for large queues\n- **Priority-based

alerts\nresourceMonitor.onAlert((alert) => {\n if (alert.severity === 'critical') {\n console.error('Critical resource alert:', alert.message);\n // Trigger emergency cleanup\n memoryManager.optimizeMemory();\n }\n});\n\n// Protected AI service calls\nasync function safeAICall(prompt: string) {\n return aiServiceCircuitBreaker.executeWithCircuitBreaker(\n 'anthropic-claude',\n () => aiService.generateResponse(prompt),\n () => ({ content: 'Service temporarily unavailable' })\n );\n}\n```\n\n### CAD Processing Pipeline\n\n```typescript\n// Batch process CAD elements with monitoring\nasync function processCADProject(elements: CADElement[]) {\n const startTime = Date.now();\n \n try {\n // Validate all elements first\n const validationResult = await batchProcessor.processCADElements(\n elements, \n 'validate',\n { priority: 'high' }\n );\n \n // Filter valid elements\n const validElements = validationResult.successful\n .filter(result => result.isValid)\n .map(result => result.element);\n \n // Optimize valid elements\n const optimizationResult = await batchProcessor.processCADElements(\n validElements,\n 'optimize',\n {\n priority: 'medium',\n onProgress: (completed, total) => {\n console.log(`Optimization: ${Math.round(completed/total*100)}%`);\n }\n }\n );\n \n // Record metrics\n const processingTime = Date.now() -
