Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes all three parameters, including the important distinction between form_id and the short share_id, so the description does not need to repeat them. It adds no new parameter-level detail; node_id remains minimally described as 'The node ID,' but the schema has 100% coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
