Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description uses 'metadata-assisted' to hint at filtering, but does not add significant meaning beyond the schema's parameter descriptions. It does not explain how parameters combine or prioritize them, so marginal value is added.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
