Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description thoroughly explains messages (last is current, rest are earlier), samples (re-runs for stability), and expect (pass true/false to get matched). Agent is the only parameter not directly explained, but it is obvious from context and the schema title.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
