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 does help by listing the three formats, which map exactly to the enum values for the 'format' parameter. It also provides context for 'sessionId' by referencing 'research session', but does not elaborate on what constitutes a valid session or the required nature of the ID.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
