Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It lists the five updatable fields and clarifies that omitting a field means it should not change, which adds real meaning beyond the nullable schema properties. However, it does not explain the allowed values or semantics of 'state', 'priority', or 'plan_status', leaving some burden on the agent to infer valid inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
