Pydantic AI is now a supported agent in AgentEnv Framework

Scale AI's open source AgentEnv Framework, which builds reproducible environments with realistic apps, data and multi-step tasks for testing agents, now supports Pydantic AI as an agent that runs in process with the Coder capability from Pydantic AI Harness. The post explains configuration via an OpenAI-compatible endpoint, a mail-mcp example bundle with a task that deploys the environment, prompts the agent and runs a verifier, and notes that swapping a2a_agent_id to claude-code lets you compare agents on the same task.
