Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema documents all five parameters. The description adds a bit of meaning to the `type` parameter ('choose the appropriate result type'), but contributes nothing about `topics`, `featured`, or `page` beyond what the schema already states, so the baseline 3 holds.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
