<objective> Covers Laravel application architecture end to end: project structure (Actions, Contracts, DTOs, Services, Repositories layout), the service container and dependency injection, service providers and facades, environment/configuration, development environments (Sail, Valet, Homestead, Octane), Artisan CLI, filesystem/processes/context, feature flags (Pennant), MCP servers, concurrency, and production deployment (including Envoy, logging, error handling, and package authoring). </objective>

Laravel Architecture Patterns

Agent Workflow (MANDATORY)

Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`:

1. **fuse-ai-pilot:explore-codebase** - Analyze existing architecture 2. **fuse-ai-pilot:research-expert** - Verify Laravel patterns via Context7 3. **mcp__context7__query-docs** - Check service container and DI patterns

After implementation, run **fuse-ai-pilot:sniper** for validation.

Overview

Laravel architecture focuses on clean separation of concerns, dependency injection, and maintainable code organization. This skill covers everything from project structure to production deployment.

When to Use

• Structuring new Laravel projects
• Implementing services, repositories, actions
• Setting up dependency injection
• Configuring development environments
• Deploying to production

---

Critical Rules

1. **Thin controllers** - Delegate business logic to services 2. **Interfaces in app/Contracts/** - Never alongside implementations 3. **DI over facades** - Constructor injection for testability 4. **Files within `FUSE_SOLID_MAX_LINES`** - Split larger files per SOLID 5. **Environment separation** - .env never committed
