## 📰 Custom Issue <!-- Provide a clear description of what the issue is, and we'll try our best to help 😀 --> Over at https://github.com/SciTools/cf-units/pull/364#discussion_r1501764951, @pelson suggested that the `test_coding_standards.py` module would be better as a pre-commit hook. I found this [insert-license](https://github.com/Lucas-C/pre-commit-hooks?tab=readme-ov-file#insert-license) is a [supported hook](https://pre-commit.com/hooks.html).
