Validate use when validating GitHub Actions workflows for Google Cloud
Why this skill is useful
Adds specific validation commands and security best practices for GitHub Actions workflows deploying to Google Cloud, which the AI wouldn't reliably generate on its own.
What it needs
Requires gcloud installed locally. Requires github, google-cloud account access. About 1k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
Gh Actions Validator Overview Validate and harden GitHub Actions workflows that deploy to Google Cloud (especially Vertex AI) using Workload Identity Federation (OIDC) instead of long-lived service account keys. Use this to audit existing workflows, propose a secure replacement, and add CI checks that prevent common credential and permission mistakes. Prerequisites Before using this skill, ensure: GitHub repository with Actions enabled Google Cloud project with billing enabled gcloud CLI authenticated with admin permissions Understanding of Workload Identity Federation concepts GitHub repository secrets configured Appropriate IAM roles for CI/CD automation Instructions 1. Audit Existing Workflows: Scan .github/workflows/ for security issues 2. Validate WIF Usage: Ensure no JSON service account keys are used 3. Check OIDC Permissions: Verify id-token: write is present 4. Review IAM Roles: Confirm least privilege (no owner/editor roles) 5. Add Security Scans: Include secret detection and vulnerability scanning 6. Validate Deployments: Add post-deployment health checks 7. Configure Monitoring: Set up alerts for deployment failures 8. Document WIF Setup: Provide one-time WIF configuration commands Output uses: actions/checkout@v4 name: Authenticate to GCP (WIF) name: Deploy to Vertex AI --project=${{ secrets.GCPPROJECTID }} \ --region=us-central1 name: Validate Deployment Error Handling See ${CLAUDESKILLDIR}/references/errors.md for comprehensive error handling.
