Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description carries the burden of explaining the single parameter. 'Explicitly selected research' hints that study_id targets one specific item rather than a bulk/recursive delete, but the required ^r_[a-f0-9]{8}$ identifier format and where to obtain it are never mentioned, so the compensation is only partial.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
