[ ] Service status properly updated on failures (setProvisionStatus('failed'))

Logging

[ ] $this->logInfo() for successful operations with context

Common Pitfalls to Avoid

❌ Don't Do This

[ ] ❌ Store API keys in code or config files (use .env variables)
[ ] ❌ Skip input validation "for internal use"
[ ] ❌ Use direct SQL queries instead of Eloquent ORM or Query Builder
[ ] ❌ Ignore error handling in background jobs (always try-catch)
[ ] ❌ Log sensitive information (passwords, API keys, personal data)
[ ] ❌ Skip database indexes for frequently queried columns
[ ] ❌ Use synchronous operations for long-running tasks (use Task::add())
[ ] ❌ Hardcode configuration values (use config() method)
[ ] ❌ Skip permission checks in controllers
[ ] ❌ Ignore rate limiting for external APIs
[ ] ❌ Use non-existent methods like queueTask() (use Task::add() directly)
[ ] ❌ Use incorrect Task::add() parameters (no 'uuid' parameter needed)
[ ] ❌ Call non-existent helper methods like getJobParameter()

✅ Best Practices

[ ] ✅ Use environment variables for sensitive configuration (.env file)
[ ] ✅ Validate all inputs with Laravel Validator rules
[ ] ✅ Use Laravel's built-in security features (CSRF, XSS protection)
[ ] ✅ Implement comprehensive error handling with try-catch blocks
[ ] ✅ Use structured logging with context (service_uuid, action, data)
[ ] ✅ Optimize database queries and add indexes on foreign keys
[ ] ✅ Use Task::add('ModuleJob', 'Module', $data, $tags) with correct parameters
[ ] ✅ Make configuration flexible using config.php and .env
[ ] ✅ Implement proper authorization checks in all controller methods
[ ] ✅ Handle external service failures gracefully with retries
[ ] ✅ Follow the real API methods from actual module classes
[ ] ✅ Use correct Task::add() parameters: $data must contain 'module' and 'method' only, no 'uuid'
[ ] ✅ Always call setProvisionStatus('processing') before queueing tasks
[ ] ✅ Store service data using setProvisionData() method

Remember: A well-designed module is secure, performant, maintainable, and provides excellent user experience. Take time to plan, implement best practices, and thoroughly test before deployment.
