Error Handling & Fallbacks

Error Categories

Error Type	Detection	Recovery Strategy
MigrationError	Schema conflicts	Rollback guidance, fresh migration
RelationshipError	N+1 query detection	Suggest eager loading
RouteError	Route not found / method not allowed	Route list debug, binding check
QueueError	Failed job handling	Retry strategy, failed_jobs table
AuthError	Guard/middleware issues	Auth config review

Error Response Template

// Laravel-specific error handling
return [
    'error_type' => 'RelationshipError',
    'message' => 'N+1 query detected in User::posts relationship',
    'detection' => 'Laravel Debugbar / Telescope',
    'fix' => 'Use eager loading: User::with("posts")->get()',
    'artisan_commands' => [
        'php artisan model:show User',
        'php artisan route:list --name=users'
    ],
    'documentation' => 'https://laravel.com/docs/eloquent-relationships#eager-loading'
];

Token & Cost Optimization

Context Management

optimization:
  max_context_files: 8
  priority_loading:
    - composer.json           # Check Laravel version
    - .env.example            # Environment structure
    - routes/web.php          # Web routes
    - routes/api.php          # API routes
    - app/Models/*.php        # Eloquent models
    - config/app.php          # App configuration

Laravel-Specific Caching

cache_patterns:
  - artisan_commands: true    # Cache command output
  - route_list: true          # Cache route:list
  - model_relationships: true # Cache relationship structures

Usage Examples

Basic Invocation

Task(subagent_type="php:02-php-laravel")

Create CRUD Resource

Task(
  subagent_type="php:02-php-laravel",
  prompt="Create a complete CRUD for Post model with API endpoints"
)

Eloquent Optimization

Task(
  subagent_type="php:02-php-laravel",
  prompt="Optimize this query for N+1 prevention",
  context={"file": "app/Http/Controllers/PostController.php"}
)

Troubleshooting Guide

Common Issues

1. "Class not found" after creating model

Symptom: New model/controller not recognized
Debug Checklist:
  [ ] Run: composer dump-autoload
  [ ] Check namespace matches directory structure
  [ ] Verify PSR-4 autoloading in composer.json
  [ ] Clear caches: php artisan optimize:clear

2. Migration Errors

Symptom: Migration fails or foreign key issues
Debug Checklist:
  [ ] Check migration order (timestamps)
  [ ] Verify referenced tables exist
  [ ] Check column types match for foreign keys
  [ ] Run: php artisan migrate:status
Commands:
  php artisan migrate:rollback --step=1
  php artisan migrate:fresh --seed  # Development only!

3. Queue Jobs Not Processing

Symptom: Jobs stuck in queue
Debug Checklist:
  [ ] Check QUEUE_CONNECTION in .env
  [ ] Verify queue worker is running
  [ ] Check failed_jobs table
  [ ] Review job's handle() method
Commands:
  php artisan queue:work --tries=3
  php artisan queue:retry all
  php artisan queue:failed

4. Route Not Found (404)

Symptom: Route exists but returns 404
Debug Checklist:
  [ ] Run: php artisan route:list | grep <route>
  [ ] Check route caching: php artisan route:clear
  [ ] Verify HTTP method (GET vs POST)
  [ ] Check middleware groups
  [ ] Verify route model binding

Debug Mode

# Full Laravel debug
php artisan about

# Route debugging
php artisan route:list --path=api/users

# Model inspection
php artisan model:show User

# Config check
php artisan config:show database
