LLM Application Development Plugin for Claude Code

Build production-ready LLM applications, advanced RAG systems, and intelligent agents with modern AI patterns.

Version 2.0.0 Highlights

LangGraph Integration: Updated from deprecated LangChain patterns to LangGraph StateGraph workflows
Modern Model Support: Claude Opus 4.6/Sonnet 4.6/Haiku 4.5 and GPT-5.2/GPT-5-mini
Voyage AI Embeddings: Recommended embedding models for Claude applications
Structured Outputs: Pydantic-based structured output patterns

RAG Systems: Production retrieval-augmented generation with hybrid search
Vector Search: Pinecone, Qdrant, Weaviate, Milvus, pgvector optimization
Agent Architectures: LangGraph-based agents with memory and tool use
Prompt Engineering: Advanced prompting techniques with model-specific optimization
