Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides almost no semantic coverage, so the description must compensate. It does give one-line explanations for both parameters: 'domain' is a filter with an example, and 'min_sharpe' is a minimum Sharpe ratio filter. This adds meaning beyond the bare schema, but details like defaults, null behavior, or filter format are not addressed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
