Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There is only one parameter, 'id', which is already named clearly in the schema. The description adds 'by id' but does not explain what kind of ID it is or any format expectations. With schema description coverage at 0%, the description barely compensates, but the parameter is self-explanatory enough to warrant a baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
