In your config example you have the URL of the pre-commit github repo instead of your repo. Shouldn't this part: "Add a .pre-commit-config.yaml file to your repository, with the following syntax: .pre-commit-config.yaml repos: - repo: https://github.com/pre-commit/pre-commit-hooks" Be "repo: https://github.com/softwaremill/scala-pre-commit-hooks"? The https://github.com/pre-commit/pre-commit-hooks repo does not have your hooks.
