Tools are mostly distinct: read_sensor, get_alarms, get_status, get_setpoints, and write_setpoint each target a specific domain area. The main overlap is get_all, which subsumes the individual getters, potentially confusing an agent about whether to call it or individual tools, though descriptions make the distinction reasonably clear.

Naming follows a consistent verb_noun pattern: read_sensor, get_alarms, get_status, get_setpoints, write_setpoint, get_all. Minor inconsistency exists with 'read' vs 'get' for data retrieval (read_sensor uses read while others use get), but this is a small deviation and the pattern is otherwise uniform.

Six tools is a well-scoped set for a PLC control server, covering the essential read and write operations without bloat. Each tool serves a clear purpose, and the count is appropriate for the domain.

The surface covers reading sensors, alarms, status, and setpoints, plus writing setpoints with safety validation. Notably missing are operations for controlling outputs (writing discrete/analog output values) and acknowledging alarms, which are common PLC tasks. However, get_all consolidates reads, and setpoint writing is the safety-relevant write path.
