Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is well-structured with defaults, ranges, and descriptions for some parameters, so the schema carries most of the parameter semantics. The tool description does not add any explanation of how parameters like source, channels, durationMs, or sampleRate affect the encoding, but the high schema coverage keeps this at the baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
