+  - Content: Simple text description
+
+- Odd numbered resources:
+  - Binary blob format
+  - URI pattern: `test://static/resource/{odd_number}`  
+  - Content: Base64 encoded binary data
+
+Resource features:

+- Demonstrates resource templates
+- Auto-updates subscribed resources every 5 seconds
+
+### Prompts
+
+1. `simple_prompt`
