Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description needs to compensate, and it partially does: 'active offer' maps to offer_id and 'exact immutable revision' clarifies revision_digest. However, it does not explicitly explain which parameter is required, that revision_digest is optional, or how the two parameters interact when both are present.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
