CI Pipeline Generator

Analyze the current project and generate a production-ready GitHub Actions CI/CD workflow.

Process

1. Detect Project Stack

Scan for:

• Language and framework (same detection as dockerfile-generator)
• Test framework (jest.config.*, pytest.ini, *_test.go, etc.)
• Linter config (.eslintrc*, .flake8, golangci-lint, clippy)
• Formatter config (.prettierrc*, black, gofmt)
• Build output (dist/, build/, target/)
• Existing CI files (.github/workflows/, .gitlab-ci.yml, Jenkinsfile)
• Docker presence (Dockerfile, docker-compose.yml)
• Deploy targets (vercel.json, netlify.toml, fly.toml, Procfile, Kubernetes manifests)

2. Generate Workflow

Create .github/workflows/ci.yml with these stages:

Lint & Format Check

• Run linter (ESLint, Flake8, golangci-lint, etc.)
• Check formatting (Prettier, Black, gofmt)
• Fail fast on style issues

Test

• Run unit tests with coverage
• Use matrix strategy for multiple versions if applicable (e.g., Node 18/20, Python 3.10/3.12)
• Cache dependencies for speed (npm cache, pip cache, Go module cache)
• Upload coverage report as artifact

Build

• Compile/build the project
• Verify build succeeds
• Upload build artifacts

Security (optional)

• Run npm audit / pip-audit / govulncheck
• Run CodeQL analysis for supported languages

Deploy (if deploy target detected)

• Deploy to detected platform (Vercel, Netlify, Fly.io, etc.)
• Only on push to main branch
• Use environment secrets

3. Best Practices

Always:

• Use specific action versions with SHA pins or major version tags (e.g., actions/checkout@v4)
• Cache dependencies (actions/cache or built-in caching)
• Set concurrency to cancel in-progress runs on same branch
• Use permissions block with least privilege
• Separate jobs for lint/test/build (parallel execution)
• Add paths-ignore for docs-only changes
• Use matrix strategy for multi-version testing when relevant

Triggers:

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

Concurrency:

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

Templates by Stack

Node.js

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm
      - run: npm ci
      - run: npm run lint

  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [18, 20]
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}
          cache: npm
      - run: npm ci
      - run: npm test -- --coverage

  build:
    needs: [lint, test]
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm
      - run: npm ci
      - run: npm run build

Python

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"
          cache: pip
      - run: pip install flake8 black
      - run: flake8 .
      - run: black --check .

  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.10", "3.12"]
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}
          cache: pip
      - run: pip install -r requirements.txt
      - run: pytest --cov

Java (Maven)

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-java@v4
        with:
          distribution: temurin
          java-version: 21
          cache: maven
      - run: mvn verify

Go

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: stable
      - uses: golangci/golangci-lint-action@v4

  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: stable
      - run: go test -race -coverprofile=coverage.out ./...

Output

1. Write .github/workflows/ci.yml
2. Print summary of what was generated:

``` ## CI Pipeline Generated

Stack: Node.js 20 (Next.js) File: .github/workflows/ci.yml

### Stages

1. Lint — ESLint + Prettier check
2. Test — Jest with coverage (Node 18, 20 matrix)
3. Build — Next.js production build
4. Deploy — Vercel (on push to main)

### Next Steps

• Add required secrets in GitHub Settings > Secrets
• Merge this workflow to main to activate

```

Notes

• If $ARGUMENTS specifies a deploy target, include deploy stage for that platform.
• If existing CI exists, read it first and offer to improve rather than overwrite.
• For monorepos, generate path-filtered workflows for each service.
