Key Capabilities
Official Microsoft SDK, first-class Azure OpenAI integration with enterprise-grade support
Multi-language support, C#, Python, and Java with consistent API design across all three
Plugin architecture for composable AI capabilities, connect LLMs to APIs, databases, and services
Built-in planner for multi-step task decomposition and autonomous agent workflows
Memory and vector store connectors for RAG with Azure AI Search, Qdrant, Pinecone, and more
Standout Features
Plugin Architecture
Composable plugins that wrap APIs, databases, and services into LLM-callable functions with automatic parameter marshalling.
AI Agent Framework
Built-in planner and agent loop for multi-step reasoning, task decomposition, and autonomous workflows.
Memory Connectors
Vector store integrations with Azure AI Search, Qdrant, Pinecone, Chroma, and more for RAG pipelines.

Community Buzz
EVERY TOOL VIBE-CODERS SHOULD KNOW ABOUT: @claudeai for coding + debugging, @cursor_ai as AI code editor, @Replit for cloud coding + deployment.
Claude for coding ($20/mo), Supabase for backend (Free), Vercel for deploying (Free), Stripe for payments. The full vibe coder stack for under $35/mo.
The entire AI coding industry just got exposed. Someone leaked the system architecture of every major tool, 30,000+ lines of hidden instructions.
