Summary
This is a comprehensive reference for building production AI agents with Pydantic AI, covering everything from basic agent setup to multi-agent orchestration. You get working patterns for tools, structured outputs, dependency injection, streaming, lifecycle hooks, and the newer capabilities system that bundles reusable behaviors like web search and extended thinking. The skill includes a routing table that points you to specific references based on what you're building, plus TestModel examples for unit testing agent behavior. It's opinionated about when to use Pydantic AI versus other frameworks and clearly separates core validation library usage from agent work. If you're already comfortable with Pydantic models and want to build LLM applications without the ceremony of LangChain, this gives you the patterns and guardrails.
