LLM Integration Skill

Integrate Large Language Models (OpenAI, Anthropic) into applications with proper streaming, structured outputs, tool calling, prompt engineering, token management, and error handling.

API Configuration and Client Setup

BAD: Hardcoded credentials, no validation

const openai = new OpenAI({
  apiKey: "sk-proj-abc123" // Hardcoded key
});

const anthropic = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY // No validation
});

GOOD: Environment validation, typed configuration
