name	debug-ros2
description	Diagnose ROS 2 systems with evidence-first checks across nodes, topics, lifecycle states, QoS, and pipeline data flow. Use when debugging ROS 2 node discovery, topic connectivity, lifecycle, message flow, QoS, or CUDA-related suspicions.

ROS2 Debug Skill

1. List all running nodes: ros2 node list
2. Check topic connections: ros2 topic list and ros2 topic info <topic>
3. Verify lifecycle states: ros2 lifecycle get <node>
4. Check data flow at each pipeline stage before diagnosing
5. Never assume QoS/CUDA issues without evidence
