Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema already provides detailed descriptions for all parameters (80% coverage), including async, threshold, currentOutputs, baselineMetrics, and modelIdentifier. Description does not add new parameter semantics beyond mentioning 'model outputs or identifiers' which aligns with schema. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
