Use the plugin when a project already has a Pylint command and configuration.
Add the plugin to pyproject.toml:
[tool.pylint]
load-plugins = ["pylint_pypy_shim"]
Then run Pylint under PyPy as usual:
uv tool run --python pypy --from 'pylint==4.*' pylint your_package
The plugin entry point calls install_patch(...) and returns. It does not add
messages, disable checkers, or alter Pylint configuration.
