Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 50%: `reference` is well documented in-schema, while `share_id` is bare. The description adds that the link is named by both share_id and the reference it was minted on, reinforcing the schema but giving no format or lookup detail for share_id.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
