Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already documents all 11 parameters at 100% coverage, so the baseline is 3. The description adds value by explicitly naming task_type, stack, and errors_encountered as triggers for writing a structured execution_report, giving them functional meaning beyond just metadata.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
