Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description carries the full burden of explaining parameters. It mentions 'Fill' but does not map any of the five parameters (name, values, uiLanguage, inputLanguage, outputLanguage) to their purpose or format. The agent is left guessing what 'values' or the language parameters mean, and the description does not compensate for the lack of schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
