Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description thoroughly explains every parameter: `api_key` is required, `file_path` is for mode B, and `skill_md`, `files`, `requirements`, `author_agent` are for mode A with examples. It also clarifies the mutual exclusivity and precedence, fully compensating for the schema's lack of descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
