First, install the package from PyPi or GitHub .

uv tool install toml-run

uv add --dev toml-run

pip install toml-run

pip install --group dev toml-run

brew install cssnr/tap/toml-run

Then, add some scripts to the pyproject.toml.

[tool.scripts]
clean = "rm -rf dist"
build = "run clean && uv run hatch build"
prelint = "echo always runs before lint"
lint = ["uv run ruff check .", "uv run ty check ."]
postlint = "echo always runs after lint"

Finally, run a script.

run build

Or, run without installing using astral-sh/uv .
