Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has only one parameter, 'input', with no description and 0% coverage. The tool description adds that the input is a 'raw user arXiv request', which gives meaningful context beyond the bare parameter name. However, it does not specify the expected format, structure, or example values, so it only partially compensates for the schema's lack of documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
