Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must add meaning. It explains the query parameter's time-range syntax with an example, adding value. However, it does not elaborate on the other four parameters (limit, cursor, sort_by, group_by), leaving gaps. The baseline is 3 due to zero coverage, and partial compensation yields a 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
