Laravel CMS uses one write path for admin, API, AI agent and mobile app

The author describes kitloom, a Laravel content management system whose admin panel, REST API, AI agent and new phone app all share a single write path. Instead of duplicating business rules in separate controllers for each interface, every entry point calls the same writer classes, which handle validation, permissions, slugs and events for the acting user. Shop logic such as checkout and cart pricing follows the same pattern, so coupons and shipping rules are defined once. Modules register their capabilities as tagged tools for the AI agent, each acting as a thin door into the shared writers. The approach, the authors say, let them build a 200-plus-tool agent with safe-by-construction permissions and a mobile backend in about two days.
