Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must explain parameters. It partially covers 'report_url' by specifying the exact URL format, but completely omits the 'usage' parameter (enum with 7 values and a default). The agent has no guidance on what 'usage' controls or how to set it, leaving a significant gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
