Quick Start

GitHub Actions uses YAML workflows defined in .github/workflows/ to automatically run tests, build images, and deploy code upon pushes or pull requests.

on: [push]
jobs:
  build:
    runs-on: ubuntu-latest

Production Patterns

Reusable Workflows

Do not duplicate CI steps across 50 repositories. Create a centralized repository containing reusable workflows (workflow_call), and have individual repositories reference them. This allows updating CI standards globally.

Architecture & Scaling

Dependency Caching

Always cache node_modules or ~/.cache/pip using the actions/cache action or built-in caching via actions/setup-node. This can reduce CI pipeline times by 50% or more.

Error Recovery

If a flaky test fails the pipeline, you can use the continue-on-error: true flag for that specific step, though it is highly recommended to fix the test rather than masking it.

Security Notes

Never use pull_request_target unless absolutely necessary, as it grants actions access to repository secrets even from forked PRs, leading to easy secret exfiltration attacks. Use OpenID Connect (OIDC) instead of storing long-lived AWS/GCP credentials in GitHub Secrets.

Why use this skill

Use this when your agent works with github-actions — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

• Referencing CLI flags or config keys that do not exist
• Using outdated major versions of tools
• Skipping lockfile or version pinning in examples

Production checklist

• [ ] Secrets in environment variables, not source code
• [ ] Error handling and logging in place
• [ ] Rate limits and timeouts configured
