Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all four parameters (limit, cursor, status, projectId) are already fully documented in the schema, including the keyset-vs-offset cursor warning. The description restates the filter intent and the cursor-copy rule but adds no semantics beyond the schema, so the baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
