Ci Scaffolding

CI/CD Scaffolding

Generate and configure CI/CD pipelines following project conventions. Supports Python (ruff + pytest + coverage) and TypeScript/JavaScript (biome + bun test) stacks, with templates for testing, documentation, and release workflows.

When to Use

• Adding CI/CD to a new project
• Updating existing GitHub Actions workflows
• Setting up pre-commit hooks for linting
• Configuring coverage reporting
• Adding release automation (tag-based)

Pipeline Templates

Python Project Pipeline

Standard Python CI pipeline:

# .github/workflows/test.yml
name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: astral-sh/setup-uv@v5
      - run: uv sync --dev
      - run: uv run ruff check .
      - run: uv run ruff format --check .
      - run: uv run pytest --cov --cov-report=xml

Key conventions:

• Use astral-sh/setup-uv (not pip)
• Ruff for both linting and formatting
• pytest with coverage (XML report for CI integration)
• No mocks in test configuration

TypeScript/JavaScript Project Pipeline

# .github/workflows/test.yml
name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: oven-sh/setup-bun@v2
      - run: bun install
      - run: bun run biome check .
      - run: bun test

Key conventions:

• Use oven-sh/setup-bun (not npm/node)
• Biome for linting and formatting
• bun test for testing

Release Workflow

Tag-based release automation:

# .github/workflows/release.yml
name: Release
on:
  push:
    tags: ['v*']
jobs:
  release:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
      - uses: actions/checkout@v4
      - uses: softprops/action-gh-release@v2
        with:
          generate_release_notes: true

Documentation Workflow

MkDocs deployment to GitHub Pages:

# .github/workflows/docs.yml
name: Docs
on:
  push:
    branches: [main]
permissions:
  contents: write
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: astral-sh/setup-uv@v5
      - run: uv sync --group docs
      - run: uv run mkdocs gh-deploy --force

Typo Checking

Add typo checking to any project:

# In existing test.yml or standalone
- uses: crate-ci/typos@master

Pre-commit Hook Setup

Python (ruff)

#!/bin/sh
# .git/hooks/pre-commit
STAGED=$(git diff --cached --name-only --diff-filter=d -- '*.py')
[ -z "$STAGED" ] && exit 0
echo "$STAGED" | xargs uv run ruff check --fix --unsafe-fixes
echo "$STAGED" | xargs uv run ruff format
git add $STAGED

TypeScript (biome)

#!/bin/sh
# .git/hooks/pre-commit
STAGED=$(git diff --cached --name-only --diff-filter=d -- '*.ts' '*.tsx' '*.js' '*.jsx')
[ -z "$STAGED" ] && exit 0
echo "$STAGED" | xargs bunx biome check --write
git add $STAGED

Scaffolding Workflow

Step 1: Detect project type

Scan for language markers (pyproject.toml, package.json, Cargo.toml, go.mod) and existing CI configuration.

Step 2: Select pipelines

Based on detection:

• Always: test workflow
• If Python with docs: docs workflow
• If releases needed: release workflow
• If no pre-commit hook: install one

Step 3: Generate files

Create .github/workflows/ directory and write workflow files. Never overwrite existing workflows without asking.

Step 4: Verify

Run act locally if available to validate workflows, or do a dry-run check of YAML syntax.
