Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema lacks any parameter descriptions, so the description must compensate. It explains how to obtain item_id (via list_roadmap), but does not explain project_id. Given the low schema coverage, this is a partial gap. The parameter list is simple, so it is adequate but not comprehensive.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
