memory_delete_record
AI agents call memory_delete_record to permanently remove resources in Awslabs Valkey — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs deletion of data records from ElastiCache/MemoryDB, which is an irreversible operation that cannot be undone. This matches the 'Destructive' category definition. Severity is high because deletion of cached data can impact application availability and data consistency, though the blast radius depends on what data is stored and how critical it is to operations.
From the tool's definition Tool name 'memory_delete_record' contains 'delete' combined with 'record', indicating irreversible data removal from a cache/memory store. Description is empty, which lowers confidence slightly but the naming convention is unambiguous.
