Cookbook 06 — Auto-Configure Your Entire Testing Pipeline

SCENARIO:
    You're launching a new AI product — a RAG-powered healthcare chatbot.
    Your PM asks: "What should we test?" You don't want to manually pick
    from 50+ metrics. Instead, describe your app and let AutoEval build
    the right pipeline for you.

    This cookbook shows how to:
    1. Generate a pipeline from a plain-English description
    2. Use pre-built templates for common app categories
    3. Run the pipeline against real inputs
    4. Export configs for CI/CD integration
    5. Customize and iterate on the auto-generated config

Usage:
    cd python && uv run python -m examples.06_autoeval
