Radar Collision Warning

This skill appears coherent with its stated goal, but review the following before installing: - Network exposure: the skill uses rosbridge over an unsecured ws:// connection (default port 8080). By default rosbridge accepts unauthenticated requests on the network. Only run this with the Raspberry Pi on a trusted LAN or protect rosbridge (firewall, VPN, or authentication) to avoid unauthorized access. - Physical-safety risk: the ROS node publishes (commented-out) flight control commands and exposes a service that could be extended to issue control messages. Before deploying on any robot or vehicle, inspect and test the code in a safe environment and ensure control topics are appropriately restricted. - Local deployment: you must install and run the Python ROS2 node and rosbridge on the Pi (the SKILL.md explains how). The Node.js client runs locally and only connects to the Pi IP you supply (RADAR_HOST / RADAR_PORT). Confirm you control that Pi and network. - Minor code issues: there are small non-security bugs (e.g., a -d test where -f was intended in the start script) and the service uses response.success to indicate a collision state (true == danger), which is a semantic choice to be aware of. If you understand and accept the network and physical-safety implications, the skill is coherent and implementable. If you plan to expose the Pi to broader networks, add authentication and firewalling for rosbridge first.
