ci4

What problem does it solve?

This Skill eliminates the common errors and inefficiencies that arise when developers apply Laravel conventions or generic PHP framework guidance to CodeIgniter 4 projects, which leads to broken functionality, security vulnerabilities, and wasted development time due to CI4's unique MVC structure, CLI tools, and authentication patterns.

Core Features & Use Cases

• Comprehensive Core CI4 Coverage: Provides accurate, up-to-date guidance for all core CodeIgniter 4 components including routing, controllers, models, query builder, views, filters, database migrations, and the Spark CLI, with explicit documentation of common pitfalls and direct comparisons to Laravel to avoid cross-framework confusion.
• Integrated Auth & API Support: Seamlessly pairs with the ci4-api and ci4-shield skills to support building REST APIs and implementing robust authentication/authorization, including session auth, token auth, JWT, 2FA, and API rate limiting.
• Real-World Use Case: For example, if you are building a multi-user content management system with CodeIgniter 4, this Skill will guide you to correctly set up resource routes, create a model with soft deletes and timestamps, implement input validation, configure filters for access control, and use Spark CLI to generate scaffolding and run migrations without common errors.
