Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description fully compensates by explaining each parameter: username (optional, defaults to current user), access_token (optional), and limit (1-100, default 100). This clarifies semantics that the schema alone does not convey, such as the range and default for limit.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
