Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% — 'seq' is an undocumented number. The description partially compensates by stating it is a 'sequence number' identifying a single reveal, giving the parameter meaning beyond the bare schema. It does not define the numbering scheme, valid range, or uniqueness, so the compensation is only partial.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
