Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description compensates by explaining account_id format ('act_XXXXXXXXX'), access_token optionality with cached token note, limit default, and campaign_id optionality. This adds value beyond the schema, though it could detail limit behavior or filter semantics more.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
