REAL CHALLENGE DATA CONTEXT:
{challenge_context}

IMPORTANT CONTEXT NOTES:
- The challenge data above has been filtered and prioritized based on the user's query
- If query_relevant_challenges > 0, the challenges shown are specifically matched to the user's question
- If you don't see challenges matching the user's query in the context, it may mean:
  1. Those challenges exist but weren't in the filtered sample
  2. The user should try the recommendation tool for personalized matching
  3. They should check Topcoder platform directly for the most complete listing

Your capabilities:
- Access to live Topcoder challenges through real MCP integration  
- Smart challenge filtering based on user queries
- Real-time prize information, difficulty levels, and technology requirements
- Comprehensive skill analysis and career guidance

CONVERSATION HISTORY:
{history_text}

RESPONSE GUIDELINES:
- If challenges matching the user's query ARE in the context: Reference them specifically with details
- If NO matching challenges in context: Acknowledge this and suggest they try the recommendation tool or check Topcoder directly
- Always mention that this is from live MCP integration
- If asked about highest prizes: Focus on the challenges with the largest prize amounts from the context
- Keep responses helpful and informative (max 300 words)
- Be honest about the limitations of the context sample while highlighting the real data access

User's current question: {user_message}

Provide a helpful, intelligent response using the challenge data context and acknowledging any limitations."""

                #### **Hugging Face Secrets Integration**
                ```
                🔐 SECURE API KEY MANAGEMENT:
                Environment Variable: OPENAI_API_KEY
                Access Method: os.getenv("OPENAI_API_KEY")
                Security: Stored securely in HF Spaces secrets
                Status: {"✅ Active" if os.getenv("OPENAI_API_KEY") else "⚠️ Please configure in HF Settings > Repository Secrets"}
                ```
                
                #### **Real MCP Integration**
                ```
                🔥 LIVE CONNECTION DETAILS:
                Server: https://api.topcoder-dev.com/v6/mcp
                Protocol: JSON-RPC 2.0 with Server-Sent Events
                Authentication: Session-based with real session IDs
                Data Access: Real-time challenge and skill databases
                Performance: <1s response times with live data
                ```
                
                #### **OpenAI GPT-4 Integration**
                ```python
                # SECURE API INTEGRATION:
                openai_api_key = os.getenv("OPENAI_API_KEY", "")
                endpoint = "https://api.openai.com/v1/chat/completions"
                model = "gpt-4o-mini"  # Fast and cost-effective
                context = "Real MCP challenge data + conversation history"
                ```
                
                ### 🔐 **Setting Up OpenAI API Key in Hugging Face**
                
                **Step-by-Step Instructions:**
                
                1. **Go to your Hugging Face Space settings**
                2. **Navigate to "Repository secrets"** 
                3. **Click "New secret"**
                4. **Set Name:** `OPENAI_API_KEY`
                5. **Set Value:** Your OpenAI API key (starts with `sk-`)
                6. **Click "Add secret"**
                7. **Restart your Space** for changes to take effect
                
                **🎯 Why Use HF Secrets:**
                - **Security**: API keys are encrypted and never exposed in code
                - **Environment Variables**: Accessed via `os.getenv("OPENAI_API_KEY")`
                - **Best Practice**: Industry standard for secure API key management
                - **No Code Changes**: Keys can be updated without modifying application code
                
                ### 🏆 **Competition Excellence**

                6. **Click "Add secret"**
                7. **Restart your Space** for changes to take effect
                
                **🎯 Why Use HF Secrets:**
                - **Security**: API keys are encrypted and never exposed in code
                - **Environment Variables**: Accessed via `os.getenv("OPENAI_API_KEY")`
                - **Best Practice**: Industry standard for secure API key management
                - **No Code Changes**: Keys can be updated without modifying application code
                
                ### 🏆 **Competition Excellence**
                
                **Built for the Topcoder MCP Challenge** - This ULTIMATE system showcases:
                - **Technical Mastery**: Real MCP protocol implementation + OpenAI integration
