py-init

name	py-init
description	Bootstrap a new Python project with uv: pyproject.toml, ruff config, .python-version, and optional src layout. Use when starting a new Python package or script project.

Task

Bootstrap a production-ready Python project named $ARGUMENTS using uv.

Steps

1. Create and enter the project directory (skip if already in it):

   uv init $ARGUMENTS --no-readme
   cd $ARGUMENTS
   

2. Configure pyproject.toml — ensure these sections exist (merge, don't overwrite):

   [tool.ruff]
   line-length = 100
   target-version = "py312"
   
   [tool.ruff.lint]
   select = ["E", "F", "I", "UP", "B", "SIM"]
   ignore = ["E501"]
   
   [tool.ruff.format]
   quote-style = "double"
   
   [tool.pytest.ini_options]
   testpaths = ["tests"]
   

3. Add dev dependencies:

   uv add --dev ruff pytest
   

4. Create .python-version if missing (use the project's required version or default to 3.12).

5. Create tests/__init__.py and tests/test_placeholder.py with a single passing smoke test.

6. Run a quick sanity check:

   uv run ruff check .
   uv run pytest
   

Report what was created. If $ARGUMENTS is empty, apply the ruff/pytest config to the current directory instead.
