"""
Continuous AI Example - CI/CD Integration for Agent Evaluation

This demonstrates how to integrate ACP-Evals into your CI/CD pipeline
for automated agent testing and quality assurance.

Supports multiple CI platforms:
- GitHub Actions (with GitHub Models)
- GitLab CI
- Jenkins
- Any CI that supports Python

Based on GitHub's Continuous AI initiative.
