Purpose

This tool is a Claude Code plugin that scans your AWS infrastructure to identify potential cost savings. It runs 163 checks across over 30 AWS services to detect idle resources and over-provisioned infrastructure.

Security Assessment

The tool requires local AWS credentials to read your infrastructure data, meaning it inherently accesses sensitive account and billing information. However, the documentation explicitly states it is read-only and will never modify or delete resources. The automated code scan of 12 files found no dangerous patterns, hardcoded secrets, or requests for risky permissions. The plugin runs locally and primarily interacts with the AWS API. Overall risk: Low.

Quality Assessment

The project is actively maintained, with the most recent code push occurring today. It uses the highly permissive MIT license, making it safe for both personal and commercial use. While the community is currently small at 17 GitHub stars, the project actively welcomes outside contributions. The repository is well-documented, offering clear installation steps, usage commands, and visual examples of expected outputs.

Verdict

Safe to use, provided your local AWS credentials are securely managed.

Quick Start

/aws-cost-saver:scan

Or just ask: Scan my AWS account for cost savings

Requirements: AWS credentials configured (aws configure or SSO), uv installed.

This tool only reads data — it never modifies or deletes anything.

Features

  • 163 checks across EC2, RDS, S3, Lambda, ECS, EKS, Aurora, SageMaker, and 30+ services
  • Parallel scanning - 11 domain agents run simultaneously
  • Confidence scoring - filters false positives
  • Real pricing - uses AWS Cost Explorer
  • Markdown reports - clean, actionable output

Commands

Command Description
/aws-cost-saver:scan Full cost optimization scan
/aws-cost-saver:reviewing-findings Review with confidence scoring
/aws-cost-saver:validating-aws-pricing Validate against AWS Pricing API

Results

Scan results - findings and savings

Before & After

60% cost reduction - $105/day to $42/day
Real AWS account: $105/day → $42/day after running the scanner
