Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description only hints at the 'prompt' parameter ('just by using text') and does not mention the critical mask requirement or the choice between file URLs and uploaded file IDs. While the schema provides detailed descriptions for these parameters, the overall schema coverage is only 50%, and the description fails to compensate by clarifying the union request structure or how to supply inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
