Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 20%, so the description must carry the load, and it does name all five inputs: row, column, an optional layer ('if not your own'), a person, and a direction. It maps the parameter kinds to the target types, though it doesn't specify that row/column must be supplied together or how they interact with person/direction.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
