Agent: DevOps Engineer File: .github/prompts/tsh-analyze-aws-costs.prompt.md

Performs a comprehensive AWS cost optimization and tagging compliance audit using a hybrid approach — analyzes IaC code first, then validates against live AWS infrastructure via API.

Usage​

/tsh-analyze-aws-costs <AWS Account/Profile, Region, or 'all'> <focus: specific service or 'everything'>

What It Does​

1. IaC Analysis​

  • Scans Terraform and CloudFormation templates for resource configurations.
  • Identifies over-provisioned instances, missing reserved instance opportunities, and inefficient storage tiers.
  • Checks tagging compliance against organizational policies.

2. Live Infrastructure Validation​

  • Queries AWS API MCP to validate actual resource usage against IaC definitions.
  • Identifies orphaned resources, unused EBS volumes, idle load balancers.
  • Checks for savings plan and reserved instance coverage gaps.

3. Cost Report​

  • Produces a detailed cost optimization report with estimated savings.
  • Prioritizes findings by potential monthly cost reduction.
  • Includes specific AWS CLI or Terraform changes for each recommendation.
