Add GitHub Actions workflow examples repository with reusable workflows, composite actions, and bash-based actions

[Copilot]

Creates a reference repository demonstrating GitHub Actions extensibility patterns: reusable workflows, composite actions, and bash-based actions.

Reusable Workflows

• CI workflow - Configurable Node.js version, optional tests, outputs results
• Deployment workflow - Multi-environment support (staging/prod), artifact handling, secret management

jobs:
  ci:
    uses: ./.github/workflows/reusable-ci.yml
    with:
      node-version: '20'
      run-tests: true

Composite Actions

• Setup action - Node.js installation, built-in caching, optional dependency install
• Build-test action - Configurable commands, coverage upload, status outputs

- uses: ./.github/actions/composite-setup
  with:
    node-version: '18'
    install-dependencies: 'true'

Bash Actions

• Simple inline - Greeting action demonstrating outputs and step summaries
• Script-based - File processor (count/list/size) with cross-platform stat compatibility

- uses: ./.github/actions/bash-script
  with:
    path: './'
    pattern: '*.md'
    operation: 'count'

Demo Workflows

Three workflows demonstrate practical usage: chained reusable workflows with deployments, composite action composition, and bash action patterns.

Documentation

• README.md - Architecture overview, usage examples, best practices
• CONTRIBUTING.md - Contribution workflow, code style, PR template
• EXAMPLES.md - Advanced patterns (matrix strategies, conditional execution, chaining)

Security

All workflows use explicit permissions (contents: read) per CodeQL requirements. Bash scripts prioritize Linux syntax for GitHub Actions compatibility.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com//advisories
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Create a repository with examples of reuseable workflows, composites and bash based actions.
