✅ Simplified Priority System - IMPLEMENTED

🎯 Changes Made

Successfully removed Chrome environment user ID logic. The LiveKit agent now uses a simplified priority system:

✅ NEW Priority Order:

1. Participant Metadata (Highest Priority)
2. Room Metadata
3. Random Generation (Fallback)

🚫 REMOVED:

• ❌ Environment variable check (CHROME_USER_ID)
• ❌ Room name pattern extraction (mcp-chrome-user-{userId})
• ❌ All environment-based user ID logic

📋 What Works Now

✅ Your Kitt.generateToken Pattern (PRIORITY 1)

const token = await Kitt.generateToken(
    "APIGXhhv2vzWxmi", // LiveKit API key
    "FVXymMWIWSft2NNFtUDtIsR9Z7v8gJ7z97eaoPSSI3w", // LiveKit API secret
    `provider_onboarding_room_${randomRoom}`, // Room name
    `provider_onboarding_particpant_${randomPartipitant}`, // Participant identity
    { tagline: "provider-register", userId: userId || null } // ✅ This is detected!
);

Result:

✅ USER_ID [METADATA] Using user ID from metadata: user_1755117838_y76frrhg2258
User ID Source: METADATA

✅ Room Metadata (PRIORITY 2)

If no participant metadata, checks room metadata:

await livekit_api.room.create_room(
    api.CreateRoomRequest(
        name="room_name",
        metadata=json.dumps({"userId": "user_123"})
    )
)

✅ Random Generation (FALLBACK)

If no metadata found anywhere:

⚠️ USER_ID [FALLBACK] No user ID found in metadata, using random session: user_1755117838_xyz789
User ID Source: RANDOM_GENERATION

🧪 Test Results: ALL PASSED

🔧 SIMPLIFIED PRIORITY SYSTEM TESTS
================================================================================
Test 1 (test_simplified_priority_system): ✅ PASS
Test 2 (test_environment_variable_ignored): ✅ PASS
Test 3 (test_room_name_pattern_ignored): ✅ PASS
Test 4 (simulate_kitt_token_only): ✅ PASS

Overall: 4/4 tests passed
🎉 SUCCESS: Simplified priority system working perfectly!
📋 Priority order: Metadata → Random
🚫 Environment variables: IGNORED
🚫 Room name patterns: IGNORED
✅ Kitt.generateToken: WORKS

🔧 Files Modified

1. agent-livekit/livekit_agent.py

• ✅ Removed environment variable check (CHROME_USER_ID)
• ✅ Removed room name pattern extraction
• ✅ Simplified priority logic to metadata → random
• ✅ Updated initialization to not require environment user ID

2. Documentation Updated

• ✅ USER_ID_PRIORITY_GUIDE.md - Updated priority order
• ✅ PRODUCTION_READY_SUMMARY.md - Removed environment examples
• ✅ Created test_simplified_priority.py - Comprehensive tests

📊 Before vs After

❌ Before (Complex):

1. Participant Metadata
2. Room Metadata
3. Room Name Pattern
4. Environment Variable
5. Random Generation

✅ After (Simplified):

1. Participant Metadata
2. Room Metadata
3. Random Generation

🎯 Expected Behavior

With Your Kitt.generateToken:

🧑 PARTICIPANT #1
   📋 METADATA FOUND:
   🎯 USER ID FOUND: userId = user_1755117838_y76frrhg2258

✅ USER_ID [METADATA] Using user ID from metadata: user_1755117838_y76frrhg2258

============================================================
NEW USER SESSION CONNECTED
============================================================
User ID: user_1755117838_y76frrhg2258
User ID Source: METADATA
============================================================

Without Metadata (Fallback):

❌ NO USER ID FOUND IN METADATA

⚠️ USER_ID [FALLBACK] No user ID found in metadata, using random session: user_1755117838_abc123

============================================================
NEW USER SESSION CONNECTED
============================================================
User ID: user_1755117838_abc123
User ID Source: RANDOM_GENERATION
============================================================

🚀 Benefits

✅ Simplified Logic

• Cleaner, more predictable behavior
• Fewer potential failure points
• Easier to debug and maintain

✅ Metadata-First Approach

• Your Kitt.generateToken pattern works perfectly
• Participant metadata has highest priority
• Room metadata as backup

✅ Reliable Fallback

• Always generates a user ID if no metadata
• No dependency on environment setup
• Consistent behavior across deployments

✅ Environment Independent

• No need to set CHROME_USER_ID environment variables
• Works in any deployment environment
• Eliminates environment-related configuration issues

🎉 Status: READY FOR PRODUCTION

✅ Simplified priority system implemented ✅ All tests passing ✅ Kitt.generateToken pattern working ✅ Environment variables ignored ✅ Room name patterns ignored ✅ Reliable fallback to random generation

Your LiveKit agent now uses a clean, simple priority system that relies on your Kitt.generateToken metadata pattern as the primary source, with reliable random generation as fallback!
