aws-review

aws-review is a skill for Claude Code from UnitOneAI/SecuritySkills. It costs 83 tokens per session (2,541 once invoked), scanned B, original, MIT.

A security review of Amazon Web Services (AWS) setups using the Center for Internet Security (CIS) AWS Foundations Benchmark, a published checklist for common cloud security controls.

In plain words
What is it for?
Use it to review Terraform, CloudFormation, CDK, AWS CLI output, IAM policies, S3 buckets, CloudTrail, VPC security groups, and RDS encryption.
Why use it?
It helps find weaknesses in identity access, storage, logging, monitoring, and network settings before they become security or audit problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

aws-review scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

**/.aws/credentials

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

AWS Security Posture Review

Overview

This skill performs a structured security assessment of AWS environments against the CIS Amazon Web Services Foundations Benchmark v3.0.0. The benchmark is organized into five sections covering identity management, storage, logging, monitoring, and networking. Each recommendation is evaluated by inspecting infrastructure-as-code definitions (Terraform, CloudFormation, CDK), AWS CLI output, or configuration files available in the repository.

The CIS AWS Foundations Benchmark v3.0.0 contains 62 recommendations across five domains. This skill evaluates each applicable control against the codebase and produces a findings report with CIS recommendation IDs, severity ratings, and actionable remediation steps.


When to Use

If a target is provided via arguments, focus the review on: $ARGUMENTS

  • Reviewing AWS infrastructure-as-code before deployment
  • Assessing an existing AWS environment's security posture against CIS benchmarks
  • Preparing for a CIS benchmark audit or compliance assessment
  • Evaluating IAM policies, S3 bucket configurations, CloudTrail settings, VPC security groups, or RDS encryption configurations
  • Onboarding a new AWS account into a security program

Context

The CIS Amazon Web Services Foundations Benchmark v3.0.0 is a consensus-driven security configuration guide developed by the Center for Internet Security. It provides prescriptive guidance for configuring AWS accounts to a hardened baseline. Organizations use it as the foundation for AWS security assessments, compliance programs (PCI DSS, HIPAA, SOC 2), and continuous monitoring.

Prerequisites

  • Access to AWS infrastructure-as-code files (Terraform .tf, CloudFormation .yaml/.json, CDK source)
  • AWS CLI output or configuration exports (if reviewing a live environment)
  • IAM policy documents (JSON)
  • S3 bucket policies and ACL configurations
  • VPC, security group, and NACL definitions
  • CloudTrail and CloudWatch configuration files

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
