Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero description coverage, so the description must compensate. It explains that 'crypto pair' corresponds to from_symbol and to_symbol, and specifies the date format for the 'date' parameter. However, it does not address the 'limit' parameter, nor does it clarify symbol ordering or formatting (e.g., base/quote convention). This partial compensation yields a middle score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
