📝

Plain-English Summary

What's actually changing, stated clearly. No parsing HCL diffs in your head.

"This plan creates a new production VPC
with 3 subnets, attaches an internet
gateway, and updates the route table
for public access."
⚠️

Risk Flags

Destructive changes, security implications, and cost impact flagged automatically.

HIGH - aws_db_instance.prod will be destroyed
MED - IAM policy scope widened to *
LOW - New CloudWatch log group
☑

Reviewer Checklist

Context-aware checks tailored to the specific changes. Not generic boilerplate.

☐ Confirm database backup before destroy
☐ Verify IAM wildcard is intentional
☐ Check subnet CIDR for overlap
📄
