-## 🔍 Trace Auditor
+## 🧪 Eval - Automated Testing
+
+AGK provides a comprehensive **evaluation framework** for testing AI workflows with semantic matching, confidence scoring, and professional reports.
+
+### Features
+- **Semantic Matching**: Embedding similarity, LLM-as-judge, or hybrid strategies
+- **Confidence Scoring**: Quantify how well outputs match expectations (0.0 - 1.0)
+- **Professional Reports**: Auto-generated markdown with collapsible sections and visualizations
+- **EvalServer Integration**: HTTP server mode for automated testing
+- **Multiple Strategies**: Choose the right evaluation approach for your use case
+
+### Quick Example
+
+```yaml
+# semantic-tests.yaml
+name: "My Workflow Tests"
+description: "Evaluate AI workflow outputs"
+
+evalserver:
+  url: "http://localhost:8787"
+  workflow_name: "story"
+  timeout: "180s"
+
+semantic:
+  strategy: "llm-judge"  # or "embedding" or "hybrid"
+  threshold: 0.70
+  llm:
+    provider: "ollama"
+    model: "llama3.2"
+
+tests:
+  - name: "Generate Report Test"
+    input: "artificial intelligence"
+    expected_output: |
+      A comprehensive technical report with structured sections
+```
+
+```bash
+# Run evaluations
+agk eval semantic-tests.yaml --timeout 200
+
+# View report
+cat .agk/reports/eval-report-*.md
