Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so form_id, updates, context and every nested field are already documented in the schema, setting the baseline at 3. The description only adds the provenance of node IDs and a pointer to clipform_get_guide, both of which the schema's own config description already mentions, so it adds little semantic value beyond structured fields.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
