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

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

Usage​

/tsh-analyze-gcp-costs <GCP Project ID, Region, or 'all'> <focus: specific service or 'everything'>

What It Does​

1. IaC Analysis​

  • Scans Terraform templates for GCP resource configurations.
  • Identifies over-provisioned instances, missing committed use discounts, and inefficient storage classes.
  • Checks labeling compliance against organizational policies.

2. Live Infrastructure Validation​

  • Queries GCP infrastructure via GCP Gcloud MCP to validate actual resource usage.
  • Identifies orphaned resources, unused persistent disks, and idle load balancers.
  • Checks for committed use discount coverage gaps.

3. Cost Report​

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