Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only the id parameter has a schema description ('ID'); name, color, order, and is_closed are undocumented. With schema description coverage at 20%, the description should compensate but instead names no parameters or expected formats. An agent cannot infer the meaning or constraints of the optional fields.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
