Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema description coverage at 0%, the description must compensate but fails to explain any parameter. The description only names the action, not the required IDs for volume and server, nor the optional region. The schema itself provides minimal info (no descriptions), so more parameter context is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
