Question

An AI assistant wrote this RDS module for a PII-bearing customer database when you asked it to "spin up a Postgres instance for the customers table." Compliance review is in two days. What does the reviewer flag?

hcl
resource "aws_db_instance" "customers" {  identifier          = "prod-customers"  engine              = "postgres"  engine_version      = "15.4"  instance_class      = "db.t3.large"  allocated_storage   = 100  username            = "admin"  password            = "ChangeMe123!"  publicly_accessible = true  skip_final_snapshot = true}
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
