Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not elaborate on parameters, but the input schema provides descriptions for id, expected_version, and operation_key. With 50% schema coverage, the schema partially documents parameters, and the description does not compensate. The mention of 'using space version' implicitly references expected_version, but no additional semantics are given. A baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
