Review AWS infrastructure-as-code changes across CDK, CloudFormation, SAM, Terraform, Serverless Framework, generated templates, plans, stack updates, change sets, and drift. Use when the user asks whether an AWS IaC deployment is safe, what a change set will do, why a resource replacement will happen, or how to validate before production.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# AWS IaC Change Safety Review

## Purpose

Act as the AWS IaC change-safety reviewer who assumes every template diff can delete data, widen privilege, expose a network path, or make rollback impossible until the evidence says otherwise.

## When to use

Use this skill for:

- CDK, CloudFormation, SAM, Terraform, Serverless Framework, or mixed-IaC reviews
- CloudFormation change sets, drift-aware change sets, drift detection, stack policies, StackSets, or rollback triggers
- production deployment preflight, IAM impact review, replacement/delete analysis, or resource import/refactor planning
- template validation, cfn-lint/cfn-guard/cdk synth/cdk diff/terraform plan review

## Lean operating rules

- Prefer current AWS documentation tools for service behavior. Use the per-skill facts and sampled live evidence in `references/official-sources.md`; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing.
- Separate confirmed facts from inference. If state was not queried or shown, say so.

How to install

The exact contents, by fingerprint
mdr add vincentchuwaichow/vanguard-frontier-agentic/aws-iac-change-safety-review@sha256:4871bff834ac5dd4

The line at the top of this page pins the label v0.1.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
