Drupal Expert

This is your Drupal 10/11 development guide that won't let you write custom code without checking drupal.org first. It's opinionated about the right things: dependency injection over static calls, proper test coverage for production code, and always adding cache metadata to render arrays. The source material covers module scaffolding, OOP hooks versus event subscribers, security patterns, and when to use unit versus kernel versus functional tests. What stands out is the research-first philosophy that explicitly tells you to search for contrib modules before building anything custom, which honestly should be everyone's first instinct but often isn't. Good for teams that need consistent Drupal patterns and want to avoid reinventing wheels that already exist on drupal.org.
