  "text": "Build an Express Agent with LlamaIndex TypeScript Workflows ⚡\n\nWe have new docs walking through a production-ready agent system that combines tool-calling capabilities with real-world deployment patterns using our TypeScript workflows framework.\n\n🤖 Create a workflow with a basic tool-calling agent loop that can execute tasks autonomously\n📊 Add state management to track agent progress and maintain context across interactions\n👤 Implement human-in-the-loop patterns for critical decisions that require human approval\n🚀 Deploy your agent to an Express server for real-world usage\n\nBuild a complete agent system from scratch, starting with basic tool calling and progressing to sophisticated state management and human oversight. You'll work with @OpenAI APIs and see how our workflow system handles complex agentic patterns with clean, readable TypeScript code.\n\nPerfect for developers who want to move beyond simple chatbots and build agents that can handle multi-step processes with proper oversight and deployment infrastructure.\n\nStart building: https://t.co/LGRtJIcmb3",
