_setup_instrumentation imports posthog.ai.pydantic_ai.instrument_pydantic_ai and raises immediately if it is absent, but python/requirements.txt still pins posthog>=6.6.1, which does not ship that module (the commit text even calls it an “upcoming PR”). With the current dependency set, selecting provider 13 or running run_all_tests will hit this ImportError and the provider cannot be used at all. Pin PostHog to a release that contains the pydantic AI instrumentation or guard the provider until that version is available.

Summary
PydanticAIProviderusing Pydantic AI's native OpenTelemetry instrumentationinstrument_pydantic_ai()function (from upcoming PR)get_weatherandtell_joketool examplespydantic-aito requirements.txtHow it works
Pydantic AI has native OTel instrumentation via
Agent.instrument_all(). The posthog-python SDK provides a customSpanExporterthat translates these OTel spans into PostHog$ai_generationand$ai_spanevents.Dependencies
This PR depends on a corresponding posthog-python PR that adds the OTel exporter and
instrument_pydantic_ai()function.Test plan
