Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents tenant, domain, query, location, limit and offset. The description restates required vs. optional roles and the page cap, which is largely duplicative of the schema's own limit note, so it adds only marginal semantic value. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
