"""Fetch GitHub repo stats using Codex inside a sandbox.

Demonstrates the return_type feature: Codex searches the web for repo
stats and returns structured JSON that is automatically parsed into a
Pydantic model.

Prerequisites:
    - OPENAI_API_KEY set in your environment

Usage:
    OPENAI_API_KEY=sk-... python examples/github_stats.py
    OPENAI_API_KEY=sk-... python examples/github_stats.py --repo pytorch/pytorch
