Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides only the name and type for memory_id, with no description (0% coverage). The description compensates by defining it as 'The ID of the memory' and supplying a concrete example ('mem_73'), and the usage text explains where such IDs come from ([ID: mem_XXX] in search results). This is adequate for a single parameter, though the semantic definition is mostly a restatement of the parameter name.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
