Pydantic just shipped a troubleshooting guide that walks you through reading validation failures in Logfire traces, cutting your debugging time in half.
The new guide [1] lands in the docs and hooks directly into the error reference pages, so you'll find it when you need it most. It's also wired into the docstrings for model_validate, TypeAdapter, and validate_call, meaning the guidance surfaces right where you're working. This matters because validation errors are often the hardest part of debugging Pydantic schemas in production. You get concrete examples of how to read a failed validation from a trace, plus setup instructions to get Logfire instrumented. Nothing groundbreaking, but it fills a gap that's been costing teams hours of Slack conversations.
