gcpspectre — GCP resource waste auditor with cost estimates. Part of SpectreHub.

• Scans Compute Engine instances, persistent disks, static IPs, snapshots, instance groups, Cloud SQL, and firewall rules
• Detects idle, orphaned, and oversized resources using Cloud Monitoring metrics
• Estimates monthly waste in USD per finding
• Supports configurable thresholds and exclusions
• Outputs text, JSON, SARIF, and SpectreHub formats

• Not a real-time monitor — point-in-time scanner
• Not a remediation tool — reports only, never modifies resources
• Not a security scanner — checks utilization, not vulnerabilities
• Not a billing replacement — uses embedded on-demand pricing
