What is the @CrewBase decorator used for?

The @CrewBase decorator provides a declarative, class-based way to define a crew's structure in Python, working alongside YAML configuration files for agents and tasks.

Lets a project keep agent and task definitions in clean, maintainable YAML files
Paired with @agent, @task, and @crew method annotations inside the decorated class
Reduces boilerplate compared to fully manual, direct instantiation of Agent, Task, and Crew objects

This pattern is one of three supported ways to configure a crew, alongside YAML/JSONC configuration and direct instantiation, and is commonly recommended for keeping larger projects organized.
