What get_cached_design does on Kiln

Why get_cached_design is rated Low
This tool retrieves stored design data without modifying, deleting, or executing operations. The verb 'Retrieve' and the read-only nature of accessing a cached item by identifier places it squarely in the Read category. The severity is low because retrieval of design data poses minimal risk even if misused by an agent—it does not alter state, execute code, or cause financial impact.
From the tool's definition Tool name 'get_cached_design' and description 'Retrieve a cached design by ID' indicate a query/retrieval operation with no side effects.
