To Reproduce

mypy is my last pre-commit hook and it fails.

poetry run pre-commit run --all-files

Your Environment

# `pre-commit install` (no flags) installs both the pre-commit and commit-msg git
# hooks, so the file checks/linters and the conventional-commit message check both run.
default_install_hook_types: [pre-commit, commit-msg]
