GitHub Actions Generator

Generate production-ready GitHub Actions workflows and custom actions following current best practices, security standards, and naming conventions. All generated resources are automatically validated using the devops-skills:github-actions-validator skill.

Quick Reference

Capability	When to Use	Reference
Workflows	CI/CD, automation, testing	`references/best-practices.md`
Composite Actions	Reusable step combinations	`references/custom-actions.md`
Docker Actions	Custom environments/tools	`references/custom-actions.md`
JavaScript Actions	API interactions, complex logic	`references/custom-actions.md`
Reusable Workflows	Shared patterns across repos	`references/advanced-triggers.md`
Security Scanning	Dependency review, SBOM	`references/best-practices.md`
Modern Features	Summaries, environments	`references/modern-features.md`

Core Capabilities

1. Generate Workflows

Triggers: "Create a workflow for...", "Build a CI/CD pipeline..."

Process:

Understand requirements (triggers, runners, dependencies)
Reference
```
references/best-practices.md
```
for patterns
Reference
```
references/common-actions.md
```
for action versions
Generate workflow with:
- Semantic names, pinned actions (SHA), proper permissions
- Concurrency controls, caching, matrix strategies
Validate with devops-skills:github-actions-validator skill
Fix issues and re-validate if needed

Minimal Example:

yaml

name: CI Pipeline

on:
  push:
    branches: [main]
  pull_request:

permissions:
  contents: read

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@08c6903cd8c0fde910a37f88322edcfb5dd907a8 # v5.0.0
      - uses: actions/setup-node@2028fbc5c25fe9cf00d9f06a71cc4710d4507903 # v6.0.0
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm test

2. Generate Custom Actions

Triggers: "Create a composite action...", "Build a Docker action...", "Create a JavaScript action..."

Types:

Composite: Combine multiple steps → Fast startup
Docker: Custom environment/tools → Isolated
JavaScript: API access, complex logic → Fastest

Process:

Use templates from
```
assets/templates/action/
```
Follow structure in
```
references/custom-actions.md
```
Include branding, inputs/outputs, documentation
Validate with devops-skills:github-actions-validator skill

See

references/custom-actions.md

for:

Action metadata and branding
Directory structure patterns
Versioning and release workflows

3. Generate Reusable Workflows

Triggers: "Create a reusable workflow...", "Make this workflow callable..."

Key Elements:

```
workflow_call
```
trigger with typed inputs
Explicit secrets (avoid
```
secrets: inherit
```
)
Outputs mapped from job outputs
Minimal permissions

yaml

on:
  workflow_call:
    inputs:
      environment:
        required: true
        type: string
    secrets:
      deploy-token:
        required: true
    outputs:
      result:
        value: ${{ jobs.build.outputs.result }}

See

references/advanced-triggers.md

for complete patterns.

4. Generate Security Workflows

Triggers: "Add security scanning...", "Add dependency review...", "Generate SBOM..."

Components:

Dependency Review:
```
actions/dependency-review-action@v4
```
SBOM Attestations:
```
actions/attest-sbom@v2
```
CodeQL Analysis:
```
github/codeql-action
```

Required Permissions:

yaml

permissions:
  contents: read
  security-events: write  # For CodeQL
  id-token: write         # For attestations
  attestations: write     # For attestations

See

references/best-practices.md

section on security.

5. Modern Features

Triggers: "Add job summaries...", "Use environments...", "Run in container..."

See

references/modern-features.md

for:

Job summaries (
```
$GITHUB_STEP_SUMMARY
```
)
Deployment environments with approvals
Container jobs with services
Workflow annotations

6. Public Action Documentation

When using public actions:

Search for documentation:

"[owner/repo] [version] github action documentation"

Or use Context7 MCP:

```
mcp__context7__resolve-library-id
```
to find action
```
mcp__context7__get-library-docs
```
for documentation

Pin to SHA with version comment:

yaml

- uses: actions/checkout@08c6903cd8c0fde910a37f88322edcfb5dd907a8 # v5.0.0

See

references/common-actions.md

for pre-verified action versions.

Validation Workflow

CRITICAL: Every generated resource MUST be validated.

Generate workflow/action file
Invoke
```
devops-skills:github-actions-validator
```
skill
If errors: fix and re-validate
If success: present with usage instructions

Skip validation only for:

Partial code snippets
Documentation examples
User explicitly requests skip

Mandatory Standards

All generated resources must follow:

Standard	Implementation
Security	Pin to SHA, minimal permissions, mask secrets
Performance	Caching, concurrency, shallow checkout
Naming	Descriptive names, lowercase-hyphen files
Error Handling	Timeouts, cleanup with `if: always()`

See

references/best-practices.md

for complete guidelines.

Resources

Reference Documents

Document	Content	When to Use
`references/best-practices.md`	Security, performance, patterns	Every workflow
`references/common-actions.md`	Action versions, inputs, outputs	Public action usage
`references/expressions-and-contexts.md`	`${{ }}` syntax, contexts, functions	Complex conditionals
`references/advanced-triggers.md`	workflow_run, dispatch, ChatOps	Workflow orchestration
`references/custom-actions.md`	Metadata, structure, versioning	Custom action creation
`references/modern-features.md`	Summaries, environments, containers	Enhanced workflows

Templates

Template	Location

Common Patterns

Matrix Testing

yaml

strategy:
  matrix:
    os: [ubuntu-latest, windows-latest]
    node: [18, 20, 22]
  fail-fast: false

Conditional Deployment

yaml

deploy:
  if: github.event_name == 'push' && github.ref == 'refs/heads/main'

Artifact Sharing

yaml

# Upload
- uses: actions/upload-artifact@v4
  with:
    name: build-${{ github.sha }}
    path: dist/

# Download (in dependent job)
- uses: actions/download-artifact@v4
  with:
    name: build-${{ github.sha }}
