Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 80%, so the schema already documents taskId, observed, evidence, nextTest, testMode, and the rest. The description adds no parameter-level detail (e.g., expected taskId origin or evidence format) beyond what the schema provides, so the baseline of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
