Builds production-grade Python agents using Pydantic for strict type validation and dependency injection.
The PydanticAI skill empowers developers to build robust, type-safe AI agents by leveraging Pydantic's powerful validation and Python's type hinting. It provides expert guidance on the single-orchestration Agent primitive, context-aware tool development, and clean dependency management via RunContext. Whether you are implementing complex model fallbacks, streaming partially-validated structured data, or bridging Python backends to Svelte frontends with the Vercel AI Adapter, this skill ensures your agent architecture is maintainable, testable, and production-ready.
