Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description for 'name' is misleading, calling it 'Highlight ID' despite the example 'Tom Hardy'. The tool description adds some clarity by mentioning 'name and surname', helping map the parameter to a person's name. With 100% schema coverage, the baseline is 3, and the description only partially compensates for the schema's poor semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
