Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate for missing parameter explanations. The phrase 'a user's rating for a release' loosely maps to username and releaseId, but it does not clarify that releaseId is required, whether username is optional, or provide any additional semantic detail beyond the schema's raw types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
