PyGenKit

Professional Python project generator -- PyPI, APT, and Launchpad ready.

Inspect existing Python projects, validate version consistency and CI/CD security, and generate GitHub Actions pipelines, Dockerfiles, and deploy configs.

Installation

pip install pygenkit

Or via uv:

uv tool install pygenkit

Quick Start

# Scaffold a complete project with CI/CD
pygenkit new my-app
cd my-app

# Inspect project structure
pygenkit inspect

# Validate versions, workflows, security
pygenkit validate

# Generate CI/CD pipelines, Docker, deploy configs
pygenkit generate

# Check system requirements
pygenkit doctor

Commands

Command	Description
new	Scaffold a complete Python project with CI/CD
init	Create pygenkit.toml in an existing project
inspect	Analyze project structure, versions, metadata
validate	Check version consistency, workflows, security
generate	Generate CI/CD, Docker, and deploy files
health	Assess project health across 7 categories
review	Review a GitHub PR diff using AI
release-check	Verify release readiness (coming soon)
doctor	Check system for required tools

Usage

# Create config
pygenkit init my-project

# Inspect project
pygenkit inspect

# Validate
pygenkit validate

# Generate GitHub Actions CI/CD pipelines
pygenkit generate

# Dry-run to preview without writing
pygenkit generate --dry-run

# Overwrite existing files
pygenkit generate --force

# Enable Docker + deploy in config, then generate:
#   [docker]
#   enabled = true
#   base_image = "3.12"
#   port = 8000
#
#   [deploy]
#   enabled = true
#   fly = true
#   heroku = true
#   railway = true

Inspect

Scans your project and reports:

• Project name, version, module
• Build backend (setuptools, hatchling, poetry, etc.)
• Python version requirement
• License type (MIT, Apache, GPL, etc.)
• Version consistency between pyproject.toml, __init__.py, debian/changelog, and git tags
• CI/CD workflow detection
• Debian packaging status

Validate

Runs three categories of checks:

• Version: consistency across pyproject.toml, __init__.py, debian/changelog, git tags
• Workflow: YAML validity, missing metadata, outdated actions (checkout@v3), SHA pin warnings, script injection
• Security: missing permissions blocks, hardcoded secrets, PyPI publish without protected environment

Generate

Generates files from Jinja2 templates based on pygenkit.toml:

GitHub Actions

File	Description
.github/workflows/ci.yml	Ruff lint, MyPy type-check, Pytest
.github/workflows/release.yml	Build wheel, create GitHub Release
.github/workflows/publish-pypi.yml	Trusted PyPI publishing
.github/workflows/publish-launchpad.yml	dput to Launchpad PPA

Docker

File	Description
Dockerfile	Multi-stage build
docker-compose.yml	Service configuration

Deploy

File	Platform
fly.toml	Fly.io
Procfile	Heroku
railway.json	Railway

Configuration (pygenkit.toml)

[project]
name = "my-app"
version = "0.1.0"
extras = ""

[ci]
python_versions = ["3.12", "3.13"]
runner = "ubuntu-latest"
lint = true
type_check = true

[release]
branch = "main"
tag_prefix = "v"
changelog = "CHANGELOG.md"

[pypi]
enabled = true
environment = "pypi"
trusted_publishing = true

[debian]
enabled = true
email = ""

base_image = "3.12"
port = 8000
volumes = []

[deploy]
enabled = false
fly = true
heroku = true
railway = true
primary_region = "iad"
port = 8000

Doctor

pygenkit doctor

Checks for:

• Python 3.12+
• Git
• GitHub CLI (gh)
• GPG
• dput
• debhelper
• twine
• build

Publishing setup

PyPI publishing uses Trusted Publishing (OIDC), so it does not require a long-lived API token. Configure the pypi environment on GitHub and authorize release.yml as a Trusted Publisher for the pygenkit project on PyPI. Set the repository variable PYPI_ENABLED=true to enable the publish step.

Launchpad publishing requires a PPA and an OpenPGP key registered with the Launchpad account. Add these secrets to the launchpad GitHub environment:

• GPG_PRIVATE_KEY
• GPG_PASSPHRASE
• GPG_KEY_ID

Development Workflow

PyGenKit itself follows the professional workflow it generates for other projects.

feature branch → Pull Request → CI checks → merge to main → tag → release

Step by step

# 1. Create a feature branch
git checkout -b feat/my-feature

# 2. Code, commit, push
ruff check src/ tests/
mypy src/pygenkit/
pytest
git add . && git commit -m "feat: description"
git push -u origin feat/my-feature

# 3. Open a Pull Request on GitHub
#    CI runs automatically on PR

# 4. After merge, tag a release
git checkout main
git pull
pygenkit release-check    # verify readiness
git tag v0.x.x
git push origin v0.x.x     # triggers Release workflow

Branch naming

Prefix	Purpose
feat/*	New features
fix/*	Bug fixes
refactor/*	Code improvements
docs/*	Documentation
ci/*	CI/CD changes

Branch Protection

The main branch must be protected in the GitHub repository settings:

Required settings

Setting	Solo	Team
Require pull request before merging	Yes	Yes
Require status checks to pass (CI)	Yes	Yes
Block force pushes	Yes	Yes
Restrict deletions	Yes	Yes
Required approvals	0	1

When working alone, skip approval requirements. When adding maintainers, set Required approvals: 1.

How to configure

GitHub repo → Settings → Branches → Add branch protection rule
  Branch name pattern: main
  ☑ Require a pull request before merging
  ☑ Require status checks to pass
  ☑ Require CI
  ☑ Block force pushes
  ☑ Restrict deletions

Requirements

• Python 3.12+
