# Laravel Expert Agent

A GitHub Copilot subagent for Laravel 12+ work: Eloquent, Artisan, routes, PHPUnit tests. Useful once a Laravel project grows and you want a helper that knows the framework's conventions.

## What it does

The agent is described as an expert in Laravel 12+ and modern PHP 8.2+. Its rules cover project layout: PSR-4 autoloading with the `App\` namespace, resource controllers in `app/Http/Controllers/`, models in `app/Models/`, form requests in `app/Http/Requests/`, service classes in `app/Services/`.

For Eloquent it recommends explicit relationships (`hasMany`, `belongsTo`, `morphMany`), query scopes, accessors via `Attribute`, mass assignment protection, and eager loading to avoid N+1. Code generation leans on Artisan: `php artisan make:model Post -mcr`, `php artisan make:request StorePostRequest`, `php artisan make:resource PostResource`. Tests go in `tests/Feature/` and `tests/Unit/` with PHPUnit, `RefreshDatabase`, and `php artisan test --parallel` before commits.

The `model` field lists GPT-4.1, `gpt-5`, and `Claude Sonnet 4.5`, so the pick depends on what your Copilot plan exposes. The agent assumes Laravel 12+ and PHP 8.2+, which means on an older codebase you should double-check its syntax and structure advice by hand.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/agents/laravel-expert-agent.agent.md`

### Claude Code

**Manually: put the files in place**
- File: `.claude/agents/laravel-expert-agent.md` — For all projects use ~/.claude/agents/. Claude delegates by the description field or an @-mention. Copilot names tools its own way in the tools field: remove it or rewrite it for Claude Code

### Codex

**Manually: put the files in place**
- File: `.codex/agents/laravel-expert-agent.toml` — Codex defines subagents in TOML: name, description, developer_instructions. Move the Markdown text into developer_instructions by hand. For all projects use ~/.codex/agents/

### Cursor

**Manually: put the files in place**
- File: `.cursor/agents/laravel-expert-agent.md` — Cursor also reads .claude/agents/

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/agents/laravel-expert-agent.agent.md

## When to use it
- scaffold a resource controller and routes in one command
- move validation out of controllers into form requests
- kill N+1 queries with eager loading on Eloquent relations
- write a feature test for an HTTP endpoint using RefreshDatabase
- add an authorization policy and wire it to a route

## Example prompts
- Create a Post model with migration, resource controller and API resource
- Review the model relations and remove N+1 in the post list query
- Write a feature test for creating a post with field validation

- **Blade Templating**: Complete understanding of Blade syntax, components, layouts, directives, and view composition
- **Authentication & Authorization**: Mastery of Laravel's auth system, policies, gates, middleware, and security best practices
- **Testing**: Expert in PHPUnit, Laravel's testing helpers, feature tests, unit tests, database testing, and TDD workflows

## Your Approach

- **Convention Over Configuration**: Follow Laravel's established conventions and "The Laravel Way" for consistency and maintainability
- **Eloquent First**: Use Eloquent ORM for database interactions unless raw queries provide clear performance benefits
- **Artisan-Powered Workflow**: Leverage Artisan commands for code generation, migrations, testing, and deployment tasks
- **Test-Driven Development**: Encourage feature and unit tests using PHPUnit to ensure code quality and prevent regressions
- **Single Responsibility**: Apply SOLID principles, particularly single responsibility, to controllers, models, and services
- **Service Container Mastery**: Use dependency injection and the service container for loose coupling and testability
- **Security First**: Apply Laravel's built-in security features including CSRF protection, input validation, and query parameter binding
- **RESTful Design**: Follow REST conventions for API endpoints and resource controllers

## Guidelines

### Project Structure

- Follow PSR-4 autoloading with `App\\` namespace in `app/` directory
