Python Project Skel

Python Project Skeleton Generator

Trigger Phrases

Activate when user says:

• "create a Python project", "new Python package", "scaffold Python"
• "Python project template", "Python skeleton", "initialize Python"
• "src-layout project", "Python library setup", "Python application starter"
• "pyproject.toml setup", "modern Python project", "UV project"
• "Python boilerplate", "start Python project from scratch"
• "hatchling project", "Python with ruff and mypy"

Creates production-ready Python project structures following modern best practices.

Quick Start

Generate a project in the current directory:

Project name: my-awesome-project

The skill prompts for required info and generates a complete project structure.

Configuration Options

Included Tool Configurations

pyproject.toml sections:

• [build-system] - Hatchling backend
• [project] - Dynamic version, classifiers, URLs
• [project.optional-dependencies] - dev group
• [dependency-groups] - UV compatibility
• [tool.hatch.version] - Points to __init__.py
• [tool.ruff] - Format + lint (E, W, F, I, B, C4, UP, ARG, SIM)
• [tool.mypy] - Strict configuration
• [tool.pytest] - Native TOML (pytest 9.0+)
• [tool.coverage] - 80% threshold
• [tool.bandit] - Security scanning
• [tool.bumpversion] - Semantic versioning with bump-my-version

Makefile targets:

• help - Categorized target list
• install, install-dev - UV-based installation
• test, test-cov, coverage - Testing variants
• lint, typecheck, security - Quality tools
• format, format-check - Ruff formatting
• quality - All checks combined
• build, clean - Package building
• version - Show current version
• bump, bump-patch - Bump patch version (0.1.0 → 0.1.1)
• bump-minor - Bump minor version (0.1.0 → 0.2.0)
• bump-major - Bump major version (0.1.0 → 1.0.0)
• bump-dry - Preview version bump (dry run)
• release - Create and push release tag (auto-bumps if tag exists)

Output Modes

1. cwd (default) - Create project in current working directory
2. path - Create at specified absolute or relative path
3. tarball - Create .tar.gz archive (useful for distribution)

Usage

Run the generator script:

python scripts/generate_project.py \
    --name my-project \
    --python-version 3.14 \
    --output-mode cwd

Or invoke interactively - the skill will prompt for required values.

Post-Generation Steps

After generation:

cd {project-name}
uv sync                    # Install dependencies
make test                  # Run tests
make quality               # Run all quality checks

Version Management

The generated project includes bump-my-version for semantic versioning:

make version               # Show current version
make bump-dry              # Preview what would change
make bump-patch            # 0.1.0 → 0.1.1
make bump-minor            # 0.1.0 → 0.2.0
make bump-major            # 0.1.0 → 1.0.0
make release               # Create tag and push (auto-bumps if tag exists)

Version bumps automatically:

• Update __version__ in src/{package_name}/__init__.py
• Create a git commit with conventional message
• Create a git tag (e.g., v0.1.1)

Customization

The generated project is a starting point. Common modifications:

• Add dependencies to [project.dependencies]
• Adjust tool configs in pyproject.toml
• Add additional test files
• Extend Makefile with project-specific targets
