Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema coverage at 50%, the description compensates well: it explains that `fields` is attribute name→human value, that special field types are resolved, that Blocking/Blocked By accept titles, Index notation, or ids, and that document fields take markdown. Only `sheetId` receives no added meaning, but its purpose is self-evident.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
