# Evaluation - Foundry Quality

This sample demonstrates agent evaluation using MEAI quality evaluators (Relevance, Coherence) via `FoundryEvals`.

## What this sample demonstrates

- Setting up `ChatConfiguration` for MEAI quality evaluators
- Using `FoundryEvals` with `Relevance` and `Coherence` evaluators
- Pattern 1: Running the agent first, then evaluating pre-existing responses
- Pattern 2: Running and evaluating in a single `agent.EvaluateAsync()` call
- Reading numeric quality scores from evaluation results
