Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description covers the only parameter (version_ids) with 'One or more inactive version ids to delete', achieving 100% coverage. The tool description adds no extra parameter detail beyond restating the inactive version constraint, so the baseline of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
