WHY IT NEEDS A POLICY

Why modify-replication-group needs a policy

The 'modify-' prefix indicates this tool creates or modifies configuration in a reversible manner (it does not delete or destroy). While the empty description reduces confidence, the naming pattern clearly suggests Write-class behavior. Severity is medium because misconfigured replication could impact data availability and consistency, but the action itself is reversible.

From the tool's definition Tool name 'modify-replication-group' indicates modification of a replication group, likely related to AWS ElastiCache or similar AWS service configuration.
