+# 🔧 Fix for Reuben OS Quiz & File Saving Issues
+
+## The Problem
+Your Hugging Face Space is using the OLD API structure. The quiz and file saving appear to work in Claude but don't actually save because the Hugging Face deployment doesn't have the new `/api/mcp-handler` route.
+
+## Quick Solution
+
+### Option 1: Deploy to Hugging Face (Recommended)
+
+1. **Push these files to your Hugging Face Space:**
+   ```bash
+   # In your Hugging Face Space repository
+   cp /Users/reubenfernandes/Desktop/Mcp-hackathon-winter25/pages/api/mcp-handler.js pages/api/
+   git add pages/api/mcp-handler.js
+   git commit -m "Add new MCP handler with session prefix strategy"
+   git push
+   ```
+
+2. **Restart Claude Desktop** with the new configuration
+
+3. **Test with your session ID:**
+   - Session: `session_1763722877048_527d6bb8b7473568`
+   - Tell Claude: "Save a test file to my session"
+
+### Option 2: Test Locally First
+
+1. **Start your local Next.js server:**
+   ```bash
+   cd /Users/reubenfernandes/Desktop/Mcp-hackathon-winter25
+   npm run dev
+   ```
+
+2. **Update Claude Desktop config to use local URL:**
+   ```json
+   {
+     "mcpServers": {
+       "reubenos": {
+         "command": "node",
+         "args": ["/Users/reubenfernandes/Desktop/Mcp-hackathon-winter25/mcp-server.js"],
+         "env": {
+           "REUBENOS_URL": "http://localhost:3000"
+         }
+       }
+     }
+   }
+   ```
+
+3. **Test the functionality locally**
+
+## What We Fixed
+
+### ✅ Simplified Architecture
+- Only 2 MCP tools: `manage_files` and `deploy_quiz`
+- Stateless prefix strategy: `{sessionId}_{filename}`
+- No complex session management
+
+### ✅ New Features
+- Save to public folder: `action: "save_public"`
+- Automatic quiz detection
+- Clean file names (prefixes hidden from users)
+
+### ✅ File Structure
+```
+/tmp/
+  session_1763722877048_527d6bb8b7473568_quiz.json
+  session_1763722877048_527d6bb8b7473568_main.dart
+  session_1763722877048_527d6bb8b7473568_japanese_song.txt
+
+/public/uploads/
+  public_files_here.txt (no session prefix)
+```
+
+## Testing Your Fix
+
+Run this command to verify everything works:
+```bash
+node test-api.js
+```
+
+You should see:
+- ✅ File save: SUCCESS
+- ✅ Quiz deploy: SUCCESS
+- ✅ File retrieval: SUCCESS
+- ✅ Public save: SUCCESS
+
+## Current Status
+
+✅ **MCP Server**: Updated and ready
+✅ **API Route**: Created but needs deployment
+❌ **Hugging Face**: Still using old API
+⏳ **Quiz Display**: Will work after deployment
+
+## Next Steps
+
+1. Deploy the new API route to Hugging Face
+2. Your quiz and file saving will work immediately
+3. No changes needed to the frontend (it already polls correctly)
+
+The Japanese song and quiz you tried to save will work as soon as you deploy the new API route!
