WHY IT NEEDS A POLICY

Why sorted_set_range_by_lex needs a policy

The description is empty, making classification difficult. The tool name 'sorted_set_range_by_lex' resembles a Redis sorted set lexicographic range query (a Read operation), but its presence on a SageMaker server is anomalous. With no description to confirm behavior, confidence is very low. Defaulting to Other due to insufficient information and contextual mismatch.

From the tool's definition Tool name 'sorted_set_range_by_lex' and empty description. The name suggests a Redis-style sorted set range query by lexicographic order, which would be a Read operation, but this is on an Amazon SageMaker AI MCP server where such a tool seems out of place.
