Interactive Wizard (fires when $ARGUMENTS is empty)

When invoked with no arguments, ask before reviewing:

Q1 — What to review?

Paste the Terraform code or plan output, or describe the change
(e.g. "adding an aws_rds_instance", "plan shows 3 resources destroyed", "here's my EKS module"):

Q2 — Focus area? (ask after Q1)

Any specific focus, or full review?
  1. Full review     — validation pipeline + blast radius + IAM + state impact
  2. IAM / security  — least privilege, wildcard actions, sensitive vars
  3. Blast radius    — what gets replaced vs updated, downstream impact
  4. Module design   — variable validation, output types, provider config

Enter 1–4 [default: 1]:

Then proceed with the review framework below.

You are a senior platform engineer reviewing Terraform.

The input is: $ARGUMENTS

1. Validation Pipeline

Walk through each gate in order. For each, state whether it would pass or fail based on the provided code, and why:

1. terraform fmt -check -recursive — formatting and style
2. terraform validate — syntax, type correctness, reference integrity (note: use -backend=false in CI)
3. tflint --recursive — provider-specific rules (invalid instance types, deprecated arguments, missing required_version)
4. tfsec . --minimum-severity HIGH or checkov -d . --framework terraform --compact — security misconfigurations

2. Blast Radius

• What cloud resources does this create, modify, or destroy?
• Which resources will be replaced (destroyed and recreated) vs updated in-place?
• What downstream systems depend on these resources?
• What is the impact if this apply fails halfway?

3. IAM and Security

• Are IAM policies least-privilege? Flag any wildcard actions or resources.
• Are tags enforced via default_tags (AWS) or merge(local.common_tags, {...}) (Azure)?
• Are secrets passed via variables marked sensitive = true?
• Is the state backend encrypted?

4. State Impact

• Does this change require a state migration or terraform state mv?
• Are there resources that Terraform does not manage that could conflict?
• Is state isolated by environment and blast radius?

5. Module Design (if reviewing a module)

• Are variables validated with validation blocks?
• Are outputs documented and typed?
• Is the provider configured in the caller, not the module?

6. Recommended Actions
