Initial Checks

• I'm using the latest version of Pydantic AI
• I've searched for my issue in the issue tracker before opening this issue

Description

The Temporal documentation page (docs/durable_execution/temporal.md) is missing the pydantic-ai[temporal] / pydantic-ai-slim[temporal] installation instructions that the DBOS and Prefect documentation pages both include.

The DBOS docs (line 58-68) and Prefect docs (line 68-77) both show:

pip/uv-add pydantic-ai[dbos]

and:

pip/uv-add pydantic-ai-slim[dbos]

The Temporal docs jump straight to brew install temporal without mentioning the Python package installation step.

This is issue #3256 which is still open; filing a fresh one with a clearer description since I have a fix ready.

Suggested Fix

Add the same installation pattern before the Temporal server setup instructions.
