Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and the description only refers to 'given batch session' without defining batch_id semantics. It does not clarify that batch_id is the identifier returned by begin_batch, nor does it specify format, validity, or required state. The description adds minimal meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
