pydantic-ai — Claude Code plugin: Pydantic AI agent code
A Claude plugin that steers Claude toward correct Pydantic AI code: patterns, decision trees and notes on common pitfalls.
/plugin install pydantic-ai@claude-plugins-official
/plugin marketplace add anthropics/claude-plugins-community
/plugin install pydantic-ai@claude-community
/plugin marketplace add anthropics/claude-plugins-officialWhat pydantic-ai does
The plugin ships a skill for Pydantic AI. SKILL.md covers the basics: agents, tools, structured output, testing and multi-agent setups. Companion references go into hooks, specs, streaming, fallback models and delegation.
Migration skills sit alongside, one per source framework: LangChain and LangGraph, Anthropic Agents SDK, Google ADK, Mastra, Agno, Pi, Claude Agent SDK, Vercel AI SDK and Eve. That suits a codebase you want to port rather than rewrite by hand.
It targets Claude only. Pydantic does not list it as a Claude plugin, yet Claude users can pick up a standalone cross-agent skill under skills/building-pydantic-ai-agents/.
What it helps with
- write Pydantic AI agents without guessing at patterns
- wire up tools and structured output correctly
- handle streaming and fallback models
- port an existing LangChain app to Pydantic AI
- build and test a multi-agent system
Example prompts for the agent
- Build a Pydantic AI agent with two tools and structured output
- Show me how to set up streaming responses in Pydantic AI
- Port this LangGraph app over to Pydantic AI
