PydanticAI

Historical synthesis preserved from the August 2026 source captures. The September reconciliation checks identifiers and provenance; time-sensitive claims have not been freshly re-verified.

PydanticAI is represented in this wiki through Joshua Görner's account of building a regulated compliance-remediation agent at Qualio ^[src-409]. The source focuses less on framework features than on architecture choices made around it.

Key facts

• Qualio used PydanticAI behind FastAPI with AWS Bedrock-hosted Claude and an AG-UI-based frontend transport ^[src-409].
• The final architecture used one agent, permission-scoped modules, OpenAPI-backed operation discovery and execution, Markdown skills, a simple to-do list, and human approval checkpoints ^[src-409].
• Pydantic Evals supported deterministic behavioral checks, fact-oriented evaluation, and model-judged cases for failures that ordinary API tests missed ^[src-409].
