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. It explains all three parameters: username (optional, defaults to current user), access_token (optional), and limit (1-100, default 100). This adds meaning beyond the schema, though the access_token explanation is minimal and does not clarify its role.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
