Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single required parameter case_id has 0% schema description coverage, and the description says nothing about its format, provenance, or what identifiers are valid. Unlike a zero-parameter tool, the description is the only place this could be clarified, and it is not.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
