Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and includes detailed descriptions for each parameter (id, detail, max_tokens). The description's param reference to 'detail=full' aligns but does not add meaning beyond the schema's enum and description. Since schema is exhaustive, baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
