GitHub Actions Scaffolder

You are scaffolding a traditional GitHub Actions YAML workflow — deterministic CI/CD automation with no AI at runtime. This is different from agentic workflows.

When to Use This Skill vs Others

Task Use This Skill Use create-agentic-workflow
Run tests on every PR
Build and publish a Docker image
Deploy to GitHub Pages
Check if PR matches the spec
Daily repo health report
Code review with AI judgment

Execution Steps

1. Gather Requirements

Ask the user for the following context:

  1. Workflow Category: What does this workflow need to do?

    • Test — run unit/integration tests on PR/push (pytest, jest, go test, etc.)
    • Build — compile, bundle, or build Docker images
    • Lint — run linters or formatters (ruff, eslint, markdownlint, etc.)
    • Deploy — publish to GitHub Pages, Vercel, AWS, etc.
    • Release — create GitHub releases, publish npm/PyPI packages
    • Security — dependency audits, SAST, secret scanning (CodeQL, trivy, etc.)
    • Maintenance — scheduled jobs, stale issue cleanup, dependency updates
    • Custom — describe the steps manually
  2. Platform/Language: What stack? (Python, Node.js, Go, Docker, .NET, etc.)

  3. Trigger Events: When should this fire?

    • pull_request — on PR open/update (most quality gates)
    • push to main — on merge to main (post-merge validation, deploys)
    • workflow_dispatch — manual run
    • schedule — cron schedule (maintenance jobs)
    • release — on GitHub Release published

2. Generate the Workflow

Run the scaffold script:

python ./scripts/scaffold_github_action.py \
  --skill-dir <path-to-skill-directory> \
  --category <test|build|lint|deploy|release|security|maintenance|custom> \
  --platform <python|nodejs|go|docker|dotnet|generic> \
  [--triggers pull_request push schedule workflow_dispatch] \
  [--name "My Workflow Name"] \
  [--branch main]

The script outputs a ready-to-use .yml file in .github/workflows/.

3. Post-Scaffold Guidance

After generating, advise the user:

  • Platform-specific secrets: Some steps require repository secrets (e.g., PYPI_TOKEN, NPM_TOKEN, DOCKER_PASSWORD, DEPLOY_KEY).
  • Pinned action versions: All generated steps use pinned @v4/@v3 action refs for security.
  • Permissions: Generated workflows declare minimal permissions (contents: read by default, elevated only when needed).
  • Review before committing: Treat workflow YAML as code — review it before merging.

4. Optional Optimization Loop (Autoresearch-Compatible)

If the workflow prompt/instructions need iterative calibration:

  1. Capture a baseline eval first.
  2. Change one dominant variable per iteration.
  3. Label each attempt as keep/discard.
  4. Log crashes/timeouts explicitly.
  5. Preserve an iteration ledger in evals/results.tsv.

GitHub Actions Key Reference

Available Trigger Events

Trigger Fires when Common for
pull_request PR opened/updated Tests, lint, security
push Branch pushed Deploy, release checks
schedule (cron) On a time schedule Maintenance, reports
workflow_dispatch Manual button click Deploys, one-off jobs
release Release published Package publishing
issues Issue opened/labeled Triage, notifications
workflow_call Called by another workflow Reusable sub-workflows

Permissions Model

permissions:
  contents: read      # Read repo files
  contents: write     # Commit files, push
  pull-requests: write # Comment on PRs
  issues: write       # Create/update issues
  packages: write     # Publish packages
  id-token: write     # OIDC (for cloud deploys)

Always declare minimum required permissions. The GITHUB_TOKEN grants no permissions by default unless declared.

Common Action Patterns

# Checkout
- uses: actions/checkout@v4

# Setup language
- uses: actions/setup-python@v5
  with:
    python-version: "3.12"

# Cache dependencies
- uses: actions/cache@v4
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements*.txt') }}

# Upload artifacts
- uses: actions/upload-artifact@v4
  with:
    name: report
    path: output/

# Publish GitHub Release
- uses: softprops/action-gh-release@v2
  with:
    files: dist/*

Next Actions

  • Continuous Improvement: Run ./scripts/benchmarking/run_loop.py --results-dir evals/experiments for controlled trigger optimization.
  • Review Loop: Run ./scripts/eval-viewer/generate_review.py to inspect quality across iterations.
  • Audit: Offer to run audit-plugin to validate the generated artifacts.
