ros2-custom-interfaces

Custom ROS 2 interfaces are defined using .msg files for messages and .srv files for services. This Skill generates pattern-accurate definitions with complete package scaffolding, CMakeLists.txt, and package.xml files ready for colcon build in ROS 2 Humble environments.

.msg files define message data types with field declarations. This Skill produces correctly formatted message definitions following ROS 2 conventions, enabling you to understand interface design patterns and build custom data types for robotics communication.

Yes. This Skill generates .msg and .srv definitions compatible with ROS 2 Humble and provides build-ready guidance for colcon compilation, ensuring your custom interfaces integrate properly with Humble's ecosystem and dependency resolution.

Building custom interfaces requires proper CMakeLists.txt configuration and package.xml dependency declarations. This Skill generates both files with correct ROS 2 build patterns, enabling colcon to compile your .msg and .srv definitions without manual configuration.

.msg files define data structures for published topics; .srv files define request-response pairs for services. This Skill demonstrates both patterns through worked examples, teaching interface design principles for different ROS 2 communication protocols.

While basic ROS 2 familiarity helps, this Skill targets educational contexts with worked examples and templates that teach interface design from the ground up, making it suitable for classroom exercises and learning robotics communication concepts.
