Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, so the description's Args section fully compensates by explaining each parameter: account_id format (act_XXXXXXXXX), access_token optionality/caching, limit default, campaign_id filter, and fetch_all pagination behavior. This adds substantial meaning beyond the schema's bare titles and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
