Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 33%, so the description should compensate, but it merely repeats that approval_ref and expected_plan_digest are required without explaining their meaning. The optional entity_count parameter is not mentioned at all, and the digest's role in verification is left implicit.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
