Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It explains 'key' (api name with allowed characters), 'label', and 'fields' (JSON array of field definitions). However, it omits 'module', 'account', and 'display_field', which are not described anywhere. This partial coverage adds meaning for the most important parameters but leaves three unexplained, so it's adequate but not comprehensive.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
