🚀 Key Features

Zero-config development environment with type safety built in.

✨ Features TLDR

• 🛠️ Dev Tools: Ruff (linting/formatting), ty (type checking, Astral), lefthook (hooks), commitlint
• 🔒 Security: gitleaks (commit/push), TruffleHog (CI), bandit (pre-push + CI), CodeQL
• 🧠 AI Ready: AGENTS.md + CLAUDE.md, default configs for Cursor, Windsurf, Claude Code
• 💪 Production: Python 3.12+, uv + uv_build, PEP 735 dependency-groups, static version
• 🚀 DX - Developer Experience: VS Code DevContainer, sensible defaults, quality documentation
• 🔄 CI/CD: GitHub Actions workflows, release-please version bumps, OIDC trusted publishing

Quick start

git clone https://github.com/smorinlabs/py-launch-blueprint.git
cd py-launch-blueprint
make hook-check          # verify toolchain (lefthook/gitleaks/bun/uv/...)
scripts/install-bun.sh
scripts/install-lefthook.sh
scripts/install-gitleaks.sh
uv sync --group dev      # PEP 735 dev tools
bun install              # commitlint deps
just check               # full quality pipeline

Install as a tool: uvx --from py-launch-blueprint py-projects (uvx needs --from because the distribution name differs from the console-script name) or pip install py-launch-blueprint && py-projects.

See AGENTS.md for the canonical command set, .github/CONTRIBUTING.md for the daily workflow, and RELEASE.md for the release flow.

Starting a new project from this template? If you use Claude Code or any agent that reads AGENTS.md, just say "create a new Python project from py-launch-blueprint" — the skill/ skill will walk you through gh repo create --template, identity collection, just init rebrand with preview, and an optional handoff to just post-init for publishing/Codecov/ReadTheDocs setup. For humans without an agent: the skill is also a copy-pasteable runbook.

🎯 Perfect For

Teams and professionals needing maintainable, type-safe Python projects following best practices.

Complete Feature List

Development Tools

• Bootstrap dependency check and install with make: Execute common development tasks with simple commands, standardizing workflows across team members.

• Command running with just: Define and run project-specific commands with a modern Make alternative, simplifying complex operations with clear syntax.

• Linting with ruff: Catch errors and enforce code style at lightning speed (10-100x faster than traditional linters), reducing waiting time and improving developer productivity.

• Type checking with mypy: Prevent type-related bugs before they occur, making your codebase more robust and easier to maintain as it grows.

• Formatting with ruff: Ensure consistent code style across your project automatically, eliminating style debates and pull request revision cycles.

• Pre-commit hooks with pre-commit: Enforce quality standards before code enters your repository, preventing bad code from ever being committed and reducing technical debt.

• TOML formatting and validation with taplo: Verify Toml files for syntax correctness, maintain consistent configuration files, ensuring readability and avoiding syntax errors in critical project settings.

• YAML validation with yamllint: Verify YAML files for syntax correctness, preventing configuration errors and deployment failures.

Project Structure & Management

• Project configuration with pyproject.toml: Organize all project settings in one standardized location, simplifying maintenance and configuration.

• Dependency groups separation: Organize dependencies into main, dev, and doc categories, preventing bloated installations and clarifying requirements as part of pyproject.toml configuration.

• Dependency management with uv: Install and manage packages at blazing speed (100x faster than pip/poetry), dramatically reducing environment setup time.

• Build system with uv_build: Build wheel and source distributions with uv's build backend and uv build.

• Versioning with explicit project metadata: Keep release tags aligned with the static version in pyproject.toml for predictable package metadata.
