Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so reason, account_id and redirect_path are already documented in the schema, including the account-authorization caveat and example redirect paths. The description adds nothing about parameters, which is acceptable at this coverage level and matches the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
