From castai-pack
Integrates CAST AI cost checks and policy validation into GitHub Actions CI/CD pipelines. Verifies Kubernetes savings thresholds, agent health, and Terraform plans before deployment.
npx claudepluginhub jeremylongshore/claude-code-plugins-plus-skills --plugin castai-packThis skill is limited to using the following tools:
Add CAST AI cost validation to CI/CD pipelines: verify savings thresholds, validate Terraform plans before apply, and gate deployments on autoscaler health.
Sets up local Kubernetes dev loop with CAST AI cost monitoring for testing autoscaler policies and iterating Terraform configs.
Provides production DevOps patterns for GitHub Actions CI/CD, Docker multi-stage builds, Kubernetes, Terraform IaC, OpenTelemetry observability, GitOps, security scanning, and cost optimization.
Audits Linux kernel patches for memory vulnerabilities like UAF, Terraform plans for cost drifts, and Kubernetes manifests for compliance using Gemini 3 Flash.
Share bugs, ideas, or general feedback.

| Issue | Cause | Solution |
|---|---|---|
| Secret not found | Missing gh secret set | Add secrets to repo |
| Savings check fails | Cluster not onboarded | Verify cluster ID is correct |
| Terraform init fails | State backend misconfigured | Check backend config |
| Agent offline in CI | Key scope mismatch | Use production API key |
