Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all parameters (mapId, name, mapType, detailedMapList) are already documented in the schema. The description adds no parameter-specific meaning beyond this, which is acceptable given the high schema coverage. However, it does not clarify partial-update behavior or parameter dependencies, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
