Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has no description for the 'row_id' parameter, so the description's 'by id' provides some meaning by indicating that 'row_id' is the product's identifier. However, it does not add constraints or clarifications beyond what the schema already implies from the property name, and coverage is 0%, so the compensation is minimal.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
