WHAT IT DOES

What manage_aws_emr_ec2_steps does on Awslabs Valkey

AI agents invoke manage_aws_emr_ec2_steps to trigger actions in Awslabs Valkey. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why manage_aws_emr_ec2_steps needs a policy

The description is empty, lowering confidence. However, AWS EMR 'steps' are units of work (e.g., Hadoop/Spark jobs) submitted to a cluster. 'Manage' implies adding, cancelling, or controlling these steps — which constitutes triggering external compute operations. This falls under Execute. Severity is high because misuse could trigger large-scale compute jobs with significant cost and resource implications.

From the tool's definition Tool name: manage_aws_emr_ec2_steps — 'manage' and 'steps' in EMR context implies submitting/running job steps on an EMR cluster
