Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaningful semantics beyond the input schema, which has 0% coverage (no descriptions for parameters). It explains 'include_notes' controls note inclusion, 'mode' defines detail levels with examples ('full', 'content', 'text'), and 'turbo_mode' enables text-only output. This compensates well for the schema's lack of documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
