Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, but the description fully compensates by documenting every parameter: issue_id, comment_id, content, project, work_item_type, and user_key. It explains defaults, environment variable fallback, and optionality, providing meaning well beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
