Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema description coverage at 0%, the description was required to compensate but contains no parameter information whatsoever — script_path, code_content, and response_format are entirely unexplained by 'Parse and validate GDScript code for syntax and type errors.' Fortuitously, the input schema's own property descriptions are strong (mutual exclusivity note, example paths, format enum), so the practical harm is limited, but the description itself contributes nothing to parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
