"""Minimal local Temporal SandboxAgent workflow example.

This example is intentionally smaller than ``temporal_sandbox_agent.py``. It starts a local
Temporal test server through the Temporal Python SDK, runs a ``SandboxAgent`` workflow against
the local Unix sandbox backend, and then shuts everything down.

It does not require the Temporal CLI, a long-running Temporal server, or cloud sandbox backend
credentials. It does require ``OPENAI_API_KEY`` because the model call runs through the Temporal
OpenAI Agents plugin as an activity.

Usage:
    uv run --extra temporal python -m examples.sandbox.extensions.temporal.local_hello_workflow
