AWS Cost Saver

Claude Code plugin for AWS cost optimization with ML-powered recommendations

AWS Cost Saver is a specialized DevOps automation agent that scans AWS accounts for cost optimization opportunities. It runs 173 automated checks across 11 service domains and integrates with AWS Compute Optimizer ML for intelligent rightsizing recommendations.

Key Features

• 173 automated checks across 11 domains:

  • Compute (EC2, EBS, AMIs) - 27 checks
  • Storage (S3, CloudWatch, Secrets) - 24 checks
  • Database (RDS, DynamoDB) - 15 checks
  • Networking (NAT, ELB, VPC, Route 53) - 18 checks
  • Serverless (Lambda, API Gateway) - 10 checks
  • Reservations (RI/SP coverage) - 12 checks

  • Storage Advanced (FSx, Backup) - 6 checks

• Zero Hallucination Pricing - 21 anti-hallucination rules ensure accurate savings estimates

• AWS Compute Optimizer ML - Free ML-powered rightsizing and idle detection

• Multi-Signal Detection - Avoids false positives with dependency checks and batch workload detection

• Confidence Scoring - Filters findings with 2-factor scoring (resource age, environment)

• Parallel Scanning - 11 domain agents run simultaneously for fast analysis

• Read-only - Never modifies or deletes anything in AWS accounts

Real Results

• 60% cost reduction - Real AWS account went from $105/day to $42/day
• Typical findings: idle EC2 instances, unattached EBS volumes, unused Elastic IPs, over-provisioned RDS, S3 lifecycle opportunities
