Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema only provides an enum of H/M with no descriptions. The description compensates by linking the pool class to 'Trial or Full round' configuration, implying what the parameter selects. Though it does not explicitly map H/M to Trial/Full, it adds meaningful context for a single parameter with zero schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
