Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. The mention 'or one in particular by ID' hints at the parameter's purpose, but does not explain the ID format, default behavior (list all when omitted), or validation constraints. The schema already shows the type but the description adds minimal value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
