Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents each parameter, including the optional project slug, required proposal uuid, and leave_out flags. The description reinforces that the proposal id comes from the preview, but it does not add meaning for the leave_out parameters beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
