WHAT IT DOES

What modify-replication-group-shard-configuration does on Awslabs Valkey

AI agents use modify-replication-group-shard-configuration to create or update resources in Awslabs Valkey — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Awslabs Valkey environment.

WHY IT NEEDS A POLICY

Why modify-replication-group-shard-configuration needs a policy

This tool modifies replication group shard configuration, which is a reversible write operation that restructures the cluster. While it can impact availability and performance, it does not delete data (not Destructive) and does not directly execute arbitrary code (not Execute). The modification of sharding configuration could affect data distribution and cluster availability, justifying high severity.

From the tool's definition Tool name 'modify-replication-group-shard-configuration' indicates modification of ElastiCache/MemoryDB replication group configuration, which changes cluster sharding structure. The verb 'modify' indicates write/update action.
