Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50%, with 'directory' documented as 'Project directory'. Adding api_key in the description beyond the bare schema would be valuable. The description does not clarify the role, format, or optionality of 'api_key', nor whether the directory must already exist or whether it will be created. Baseline 3 is fair because the schema does describe the 'directory' parameter, but meaningful parameter semantics are still missing.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
