Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and the enum values are individually explained in the schema (confirmed, reported, estimate, usd, unlisted, none). The description only says 'Optional filter by status' and 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.
