Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3; the description adds meaning by explaining the no-argument retrieval mode and the preview-then-confirm sequence. It restates some of the schema's `answers` type guidance, and it does not fully spell out how to discover question `id`s beyond the initial survey response, so it falls just short of a 5.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
