Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is only 50%: deviceId is documented in the schema, but pid is a bare number with no schema description. The description only repeats that a PID is used, without clarifying format, whether it must be local to the selected device, or what happens when the PID is invalid, so it does not compensate for the coverage gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
