Validate use when validating GitHub Actions workflows for Google Cloud and Vertex AI deployments. Trigger with phrases like "validate github actions", "setup workload identity federation", "github actions security", "deploy agent with ci/cd", or "automate vertex ai deployment". Enforces Workload Identity Federation (WIF), validates OIDC permissions, ensures least privilege IAM, and implements security best practices.

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

Audit Existing Workflows: Scan .github/workflows/ for security issues
Validate WIF Usage: Ensure no JSON service account keys are used
Check OIDC Permissions: Verify id-token: write is present
Review IAM Roles: Confirm least privilege (no owner/editor roles)
Add Security Scans: Include secret detection and vulnerability scanning
Validate Deployments: Add post-deployment health checks
Configure Monitoring: Set up alerts for deployment failures
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.GCP_PROJECT_ID }} \
        --region=us-central1
  - name: Validate Deployment
