This organization is dedicated to filling extra developer tooling & application utilities for ROS 2. The definition of "tooling" is very broad here, but its scope excludes the core functionality of ROS as a middleware framework.
The "Rosbag2 & Tooling Working Group" uses this org as a home base for work outside the core.
For a sense of the type of tooling maintained here:
- GitHub Actions for CI of ROS projects
- ROS 2 Graph Monitor: observes and reports overall state and health of your application, including complete topic statistics
topic_tools: nodes for manipulating topics in your application- Rosbag2 B-Roll extension for dealing with encoded video streams
