Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but the parameter descriptions are generic and seem mismatched to fetching robots.txt (e.g., 'normalize or cite', 'JSON text to validate'). The tool description adds no clarification on how url, host, json, and zone relate to the task, so an agent cannot confidently select or fill parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
