Graded relative to schema coverage. If schemaDescriptionCoverage is above 80%, the baseline is 3 even when the description says nothing about parameters, because the schema already does the work. If coverage is below 50%, the description must compensate. Either channel earns the credit: what is graded is whether an agent can fill the parameter in.

baseline when schema description coverage is above 80%, even if the description says nothing about parameters

• Document every parameter, in the schema or in the description. Either channel earns the credit; what is graded is whether an agent can fill the parameter in.
• Per-property descriptions and enums raise schemaDescriptionCoverage, which lifts your baseline to 3 on its own.
