-# CLAUDE.md - Twilio WordPress Plugin Documentation
-
-This file provides comprehensive guidance to Claude Code (claude.ai/code) when working with the Twilio WordPress Plugin codebase.
-
-## 🚨 CRITICAL: Testing & Deployment Environment
-
-**THIS PLUGIN RUNS ON A REMOTE SERVER IN A DOCKER CONTAINER - NOT LOCALLY**
-- **Production Server Path**: `/home/shadowdao/public_html/wp-content/plugins/twilio-wp-plugin/`
-- **Production URL**: `https://phone.cloud-hosting.io/`
-- **Development Path**: `/home/jknapp/code/twilio-wp-plugin/`
-- **Deployment Method**: Files synced via rsync from development to Docker container
-
-**IMPORTANT NOTES**: 
-- NEVER assume local testing - all tests must work on remote server
-- Direct PHP tests work (`php test-twilio-direct.php send`)
-- WordPress admin context has issues that need investigation
-- The plugin requires Twilio PHP SDK v8.7.0 to function
-
-## 📞 Standardized Phone Number Variable Names
-
-**THESE NAMING CONVENTIONS MUST BE STRICTLY FOLLOWED:**
-
-### Required Variable Names:
-- **`incoming_number`** = Phone number that initiated contact (sent SMS/call TO the system)
-- **`agent_number`** = Phone number used to reach a specific agent
-- **`customer_number`** = Phone number of customer calling into the system  
-- **`workflow_number`** = Twilio number assigned to a specific workflow
-- **`queue_number`** = Twilio number assigned to a specific queue
-- **`default_number`** = Default Twilio number when none specified
-
-### BANNED Variable Names (DO NOT USE):
-- ❌ `from_number` - Ambiguous, could be customer or system
-- ❌ `to_number` - Ambiguous, could be agent or system  
-- ❌ `phone_number` - Too generic, must specify whose number
-- ❌ `$agent_phone` - Use `$agent_number` instead
-
-### Test Numbers:
-- **Twilio Number**: `+19516215107` 
-- **Test Agent Number**: `+19095737372`
-- **Fake Test Number**: `+19512345678` (DO NOT SEND SMS TO THIS)
-
-### Legacy Webhook URLs:
-- **SMS**: `https://www.streamers.channel/wp-json/twilio-webhook/v1/sms`
-- **Voice**: `https://www.streamers.channel/wp-json/twilio-webhook/v1/voice`

-
-### Recording Management (Fixed)
-- **Issue**: "Unknown subresource update" error
-- **Fix**: Proper SDK v8 syntax using call recordings subresource
-- **Fallback**: Tries `Twilio.CURRENT` if specific SID fails
-
-### Queue Management (Fixed)
-- **Issue**: `Enqueue::waitUrl()` undefined method
-- **Fix**: Pass `waitUrl` as option: `$response->enqueue($queue_name, ['waitUrl' => $url])`
-
-### TTS Integration (UNIVERSALLY ENHANCED)
-- **Universal Coverage**: All call control functions now use `TWP_TTS_Helper::add_tts_to_twiml()`
-- **ElevenLabs Integration**: Automatic premium voice synthesis when configured
-- **Intelligent Fallback**: Seamless fallback to Twilio's Alice voice
-- **Cache Duration**: 30 days for identical text with automatic cleanup
-- **Performance**: Instant cached audio delivery
-- **Professional Messages**: 
-  - Hold: "Please hold while we prepare your call"
-  - Transfer: "Transferring to extension X" or "Transferring your call"
-  - Requeue: "Placing you back in the queue. Please hold."
-- **Consistency**: Same voice experience across all call operations
-- **Configuration**: Works with existing ElevenLabs API key settings
-- **Integration Points**: Hold operations, all transfer types, requeue operations, workflow steps
-
-## 🚀 Twilio Integration Details

-### API Response Structure
+# Twilio WordPress Plugin - Quick Reference
+
+## Environment
+- **Production**: `/home/shadowdao/public_html/wp-content/plugins/twilio-wp-plugin/`
+- **Dev**: `/home/jknapp/code/twilio-wp-plugin/`
+- **URL**: `https://phone.cloud-hosting.io/`
+- **Deployment**: rsync to Docker (remote server only, not local)
+- **SDK**: Twilio PHP SDK v8.7.0
+
+## Phone Variable Names
+**Use**: `incoming_number`, `agent_number`, `customer_number`, `workflow_number`, `queue_number`, `default_number`  
+**Don't use**: `from_number`, `to_number`, `phone_number`, `$agent_phone`  
+**Test numbers**: Twilio `+19516215107`, Agent `+19095737372`
+
+## Key Classes
+- **TWP_Twilio_API**: Use `new TWP_Twilio_API()` not singleton
+- **TWP_Admin**: Has `find_customer_call_leg()` - CRITICAL for call control
+- **TWP_TTS_Helper**: ElevenLabs/Alice fallback, 30-day cache
+- **TWP_User_Queue_Manager**: Auto-creates queues/extensions (100-9999)
+- **TWP_Webhooks**: 26 endpoints at `twilio-webhook/v1`
+- **TWP_Activator**: Creates 15 DB tables, run `ensure_tables_exist()` if missing
+
+## Database
+15 tables with `twp_` prefix. Key notes:
+- `twp_call_queues`: User queues (general/personal/hold)
+- `twp_agent_status`: Has `auto_busy_at` for 1-min auto-revert
+- `twp_queued_calls`: Uses `enqueued_at` not `joined_at`
+
+## Critical Functions
+
+### Call Control (MUST use call leg detection)
 ```php
-// Success response
-[
-    'success' => true,
-    'data' => [...] // Twilio response data
-]
-
-// Error response  
-[
-    'success' => false,
-    'error' => 'Error message',
-    'code' => 400
-]
-```
-
-### TwiML Generation Best Practices
-- Always use SDK classes for TwiML generation
-- Include proper XML headers when needed
-- Use TTS helper for voice synthesis
-- Implement proper error handling
-
-### Recording Stop Methods (SDK v8)
-```php
-// Method 1: Specific recording
-$client->calls($call_sid)
-       ->recordings($recording_sid)
-       ->update(['status' => 'stopped']);
-
-// Method 2: Single active recording
-$client->calls($call_sid)
-       ->recordings('Twilio.CURRENT')
-       ->update(['status' => 'stopped']);
-```
-
-## 🛠️ Development Guidelines
-
-### Call Control Functions (CRITICAL)
-**ALWAYS use call leg detection for hold, transfer, and requeue operations:**
-```php
-// Correct pattern for call control functions
-private function find_customer_call_leg($call_sid, $api) {
-    // Detects browser phone vs regular calls
-    // Uses parent call relationships
-    // Searches active calls for customer leg
-    // Returns correct SID for operations
-}
-
-// Usage in AJAX handlers
+// ALWAYS do this for hold/transfer/requeue:
 $customer_call_sid = $this->find_customer_call_leg($call_sid, $twilio);
-$result = $api->update_call($customer_call_sid, ['twiml' => $twiml_xml]);
+$api->update_call($customer_call_sid, ['twiml' => $twiml_xml]);
 ```
 
-**Why This Matters:**
-- Outbound calls create separate agent and customer call legs
-- Applying actions to agent leg disconnects customer
-- Browser phone calls use `client:` identifiers
-- Customer leg must be identified for proper call control
+### Common Fixes
+- Recording: Use `Twilio.CURRENT` for SDK v8
+- Queue: Pass `waitUrl` as option in `enqueue()`
+- TwiML: Use SDK classes, not raw XML
 
-### Database Operations
-- Always use `$wpdb` global
-- Sanitize with `sanitize_text_field()`, `intval()`
-- Use prepared statements: `$wpdb->prepare()`
-- Call `TWP_Activator::ensure_tables_exist()` before operations
+## Recent Changes (v2.3.0)
+- Browser phone moved to admin-only
+- Call control uses `find_customer_call_leg()` to prevent disconnections
+- Auto-creates user queues/extensions when needed
+- Firefox support added
+- 1-min agent status auto-revert
 
-### AJAX Handler Pattern
-```php
-public function ajax_handler_name() {
-    if (!$this->verify_ajax_nonce()) {
-        wp_send_json_error('Invalid nonce');
-        return;
-    }
-    
-    // Handler logic
-    
-    wp_send_json_success($data);
-}
-```
+## Development Notes
+- **API**: E.164 format (+1XXXXXXXXXX)
+- **Database**: Use `$wpdb`, prepared statements
+- **AJAX**: Verify nonce, return JSON
+- **Naming**: TWP_ for classes, twp_ for tables/options
+- **Debugging**: Look for "TWP Call Leg Detection" in logs
 
-### Error Handling
-- Log errors with `error_log()`
-- Return structured error responses
-- Implement fallback mechanisms
-- Handle Twilio exceptions properly
-
-### Naming Conventions
-- Classes: `TWP_Class_Name`
-- Tables: `twp_table_name`
-- Options: `twp_option_name`
-- AJAX actions: `twp_action_name`
-- Nonces: `twp_ajax_nonce` or `twp_frontend_nonce`
-
-## 📋 Common Issues & Solutions
-
-### Database Issues
-- **Missing Tables**: Run `TWP_Activator::ensure_tables_exist()`
-- **Schema Changes**: Check `add_missing_columns()` method
-- **Migration Issues**: Review `migrate_tables()` implementation
-
-### Webhook Issues
-- **500 Errors**: Check PHP error logs
-- **TwiML Errors**: Verify XML structure
-- **Authentication**: Webhooks use `__return_true` permission
-
-### API Issues
-- **Instantiation**: Use `new TWP_Twilio_API()` not singleton
-- **Phone Format**: Always use E.164 format (+1XXXXXXXXXX)
-- **Call SID**: Access via `$response['data']['sid']`
