WHAT IT DOES

What identity_update_workload_identity does on Awslabs Valkey

AI agents use identity_update_workload_identity 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 identity_update_workload_identity needs a policy

The 'update' action implies writing or modifying identity/IAM-related configuration. This is categorized as Write rather than Execute because it appears to modify identity state rather than trigger arbitrary code execution. Severity is medium because misconfiguration of workload identity could impact access control but is typically reversible.

From the tool's definition Tool name 'identity_update_workload_identity' indicates modification of identity configuration. The description is empty, limiting precision, but 'update' in the name suggests reversible changes to workload identity settings.
