Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and the description adds 'for a number of outcomes' which clarifies that num_outcomes is that number. This adds meaning beyond the schema's bare type definition, but does not specify range, integer vs float, or format. Baseline 3 due to low coverage and partial compensation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
