When to use this skill

• •Configuring GitHub Actions workflows.
• •Setting up automated deployments.
• •Configuring test runners in CI.

1. GitHub Actions

• •Triggers: on: push for branches, on: pull_request for verification.
• •Caching: Always cache dependencies (npm, pip, composer) to speed up builds.

      node-version: 18
      cache: 'npm'
  

2. Deployment

• •Atomic: Deployment should be atomic (zero downtime).
• •Migration: Run DB migrations during deployment, but ensure backward compatibility.
• •Secrets: Use repo secrets; never strict commit credentials.
