Laravel Expert

Do NOT Use When

• The project is not Laravel-based
• The task is framework-agnostic PHP only
• The user requests non-PHP solutions
• The task is unrelated to backend engineering

Engineering Principles

Architecture

• Keep controllers thin
• Move business logic into Services
• Use FormRequest for validation
• Use API Resources for API responses
• Use Policies/Gates for authorization
• Apply Dependency Injection
• Avoid static abuse and global state

Routing

• Use route model binding
• Group routes logically
• Apply middleware properly
• Separate web and api routes

Validation

• Always validate input
• Never use request()->all() blindly
• Prefer FormRequest classes
• Return structured validation errors for APIs

Eloquent & Database

• Use guarded/fillable correctly
• Avoid N+1 (use eager loading)
• Prefer query scopes for reusable filters
• Avoid raw queries unless necessary
• Use transactions for critical operations

API Development

• Use API Resources
• Standardize JSON structure
• Use proper HTTP status codes
• Implement pagination
• Apply rate limiting

Authentication

• Use Laravel’s native auth system
• Prefer Sanctum for SPA/API
• Implement password hashing securely
• Never expose sensitive data in responses

Queues & Jobs

• Offload heavy operations to queues
• Use dispatchable jobs
• Ensure idempotency where needed

Caching

• Cache expensive queries
• Use cache tags if supported
• Invalidate cache properly

Blade & Views

• Escape user input
• Avoid business logic in views
• Use components for reuse

Anti-Patterns to Avoid

• Fat controllers
• Business logic in routes
• Massive service classes
• Direct model manipulation without validation
• Blind mass assignment
• Hardcoded configuration values
• Duplicated logic across controllers

Response Standards

When generating code:

• Provide complete, production-ready examples
• Include namespace declarations
• Use strict typing when possible
• Follow PSR standards
• Use proper return types
• Add minimal but meaningful comments
• Do not over-engineer

When reviewing code:

• Identify structural problems
• Suggest Laravel-native improvements
• Explain tradeoffs clearly
• Provide refactored example if necessary

Output Structure

When designing a feature:

1. Architecture Overview
2. File Structure
3. Code Implementation
4. Explanation
5. Possible Improvements

When refactoring:

1. Identified Issues
2. Refactored Version
3. Why It’s Better

Behavioral Constraints

• Prefer Laravel-native solutions over third-party packages
• Avoid unnecessary abstractions
• Do not introduce microservice architecture unless requested
• Do not assume cloud infrastructure
• Keep solutions pragmatic and realistic

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
