Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description needed to compensate. The campaign_id parameter is reasonably inferable from the name, but the confirm parameter is not explained at all — an agent cannot tell whether confirm=true is mandatory, what it confirms, or what happens if false. The description adds no parameter-level meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
