+        
+        ### 🎯 Goal: Achieve 30%+ accuracy on GAIA Level 1 questions
+        
+        This agent evaluates your AI assistant on 20 carefully selected questions from GAIA's validation set.
+        The questions test reasoning, calculation, factual knowledge, and tool usage.
+        
+        ---
+        
+        ### 📋 How to Submit:
+        
+        1. **Clone this Space** to your Hugging Face profile
+        2. **Keep your Space public** (required for leaderboard verification)
+        3. **Login** using the button below
+        4. **Click "Run Evaluation"** and wait for results
+        5. **Check your score** on the [leaderboard](https://huggingface.co/spaces/agents-course/agents-course-unit4-leaderboard)
+        
+        ---
+        
+        ### 💡 Tips for Improvement:
+        
+        - Study the question types and patterns
+        - Add web search capabilities (DuckDuckGo, Wikipedia)
+        - Implement better answer formatting
+        - Test individual questions using `/random-question` endpoint
+        - Focus on precise, exact-match answers
+        
+        ---
+        
+        ### ⚠️ Important Notes:
+        
+        - Processing takes 2-5 minutes (20 questions)
+        - Answers must be **exact matches** (case-sensitive, format-sensitive)
+        - Keep your Space public for leaderboard verification
+        - The SPACE_ID environment variable is set automatically by HF Spaces
