Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so every parameter (tags, topic, status, project, max_sessions) is already documented in the schema with examples and a default. The description adds no syntax, format, or interaction detail beyond what the schema provides, making the baseline 3 correct.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
