Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents 'row', 'col', 'text', and 'style'. The description adds the zero-index note, which is already present in the schema parameter descriptions. It adds no additional meaning about parameter usage, values, or format. Baseline 3 applies because the schema handles parameter semantics sufficiently.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
