Walking up to a cabinet with no register map is risky, because a wrong poll can fault live equipment. This tool stays in listen-only mode, infers baud rate, node IDs and register maps from traffic already on the wire, and hands the results to an agent.
For controls engineers doing brownfield surveys: map an undocumented Modbus, CAN or J1939 network before anyone touches it.
It gives an agent the robot's topics, maps and camera feeds, and a read-only mode removes every tool that can send a command. Look first, touch later is the right order for agents near moving equipment.
For automation engineers running inspection robots, crawlers or AMRs: let the agent read the robot's state before you ever let it publish a command.
Given only the model number, Claude Code found the TV on wifi, removed 25 Xiaomi packages and wrote a new launcher. The same move applies to locked-down devices on a plant network: an agent can find and reshape them fast, which cuts both ways for OT security.
A prototype walks kids through how a pump works, step by step. The same format could teach new hires how the equipment in front of them works.
