laravel best practices rules
When reviewing or writing code, apply these guidelines:
- Use Eloquent ORM instead of raw SQL queries when possible.
- Implement Repository pattern for data access layer.
- Use Laravel's built-in authentication and authorization features.
- Utilize Laravel's caching mechanisms for improved performance.
- Implement job queues for long-running tasks.
- Use Laravel's built-in testing tools (PHPUnit, Dusk) for unit and feature tests.
- Implement API versioning for public APIs.
- Use Laravel's localization features for multi-language support.
- Implement proper CSRF protection and security measures.
- Use Laravel Mix for asset compilation.
- Implement proper database indexing for improved query performance.
- Use Laravel's built-in pagination features.
- Implement proper error logging and monitoring.
laravel package coding standards
When reviewing or writing code, apply these guidelines:
- File names: Use kebab-case (e.g., my-class-file.php)
- Class and Enum names: Use PascalCase (e.g., MyClass)
- Method names: Use camelCase (e.g., myMethod)
- Variable and Properties names: Use snake_case (e.g., my_variable)
- Constants and Enum Cases names: Use SCREAMING_SNAKE_CASE (e.g., MY_CONSTANT)
laravel package development guidelines
When reviewing or writing code, apply these guidelines:
- Use PHP 8.3+ features where appropriate
- Follow Laravel conventions and best practices
- Utilize the spatie/laravel-package-tools boilerplate as a starting point
- Implement a default Pint configuration for code styling
- Prefer using helpers over facades when possible
- Focus on creating code that provides excellent developer experience (DX), better autocompletion, type safety, and comprehensive docblocks
laravel package structure
When reviewing or writing code, apply these guidelines:
- Outline the directory structure for the package
- Describe the purpose of each main directory and key files
- Explain how the package will be integrated

Consolidated Skills

Iron Laws
- ALWAYS use parameterized queries or Eloquent ORM — raw SQL with string interpolation is the primary SQL injection vector in PHP; Eloquent's query builder parameterizes all values automatically.
- NEVER store passwords with or — these are fast hashes that GPUs crack in seconds; use with or for all password storage.
- ALWAYS declare at the top of every PHP file — without strict types, PHP silently coerces mismatched types, hiding bugs that only surface under unexpected inputs.
- NEVER catch generic without re-throwing or specific handling — swallowing all exceptions masks errors and allows corrupt state to propagate silently through the application.
- ALWAYS validate all user input at the controller boundary using Laravel's or Form Requests — never trust , , or directly in business logic.
Anti-Patterns
| Anti-Pattern | Why It Fails | Correct Approach |
|---|
| Raw SQL with string interpolation | Primary SQL injection vector; user input executed as SQL | Use Eloquent ORM or PDO parameterized queries for all database access |
| Passwords stored with md5() or sha1() | Fast hashes cracked in seconds by GPU rainbow tables | Use with or |
| Missing | PHP silently coerces types; bugs hide until unexpected inputs arrive | Declare <?php declare(strict_types=1);
at the top of every PHP file |
| Catching generic silently | Masks errors; corrupt state propagates; impossible to debug | Catch specific exceptions; log with context; re-throw or handle explicitly |
| Directly using / without validation | Enables injection, XSS, and business logic bypass | Validate at controller boundary using or Form Requests |
Memory Protocol (MANDATORY)
Before starting:
bash
cat .claude/context/memory/learnings.md
After completing: Record any new patterns or exceptions discovered.
ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
