Pydantic AI Updates: May 2, 2026

1. Pydantic AI v1.89.1 Adds Bundled Library Skills for Coding Agents

Pydantic AI. Pydantic AI v1.89.1 ships bundled Library Skills, a curated set of skill definitions intended to improve the coding-agent experience without requiring authors to assemble skill packs themselves. The patch also restores wrap_validation_errors on ToolManager function-tool methods, which had regressed, and defers anyio.Lock creation so that locks bind to the running event loop rather than capturing a stale loop reference at import time. The latter fix matters for anyone running Pydantic AI inside long-lived async services where event loops may be created after module import. Source
