Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains 'competitor' via 'optionally narrowed to a single competitor name' and implies time from 'recent', but does not explain 'to', 'from', or 'limit' parameters. The limit parameter is not mentioned, and the date-range semantics are left vague.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
