Thank you for opening a PR!

Here are a few important guidelines and requirements to check before your PR can be merged:

• [x] There is an informative high-level description of the changes.
• [x] The description and/or commit message(s) references the relevant GitHub issue(s).
• [x] pre-commit is installed and set up.
• [x] The commit messages follow these guidelines.
• [x] The commits correspond to relevant logical changes, and there are no commits that fix changes introduced by other commits in the same branch/BR. If your commit description starts with "Fix...", then you're probably making this mistake.
• [x] There are tests covering the changes introduced in the PR.

Don't worry, your PR doesn't need to be in perfect order to submit it. As development progresses and/or reviewers request changes, you can always rewrite the history of your feature/PR branches.

If your PR is an ongoing effort and you would like to involve us in the process, simply make it a draft PR.

We need to make it so that "Check code style" runs when the pre-commit config changes. Right now, the requisite check is being skipped.

Is this a hook specified somewhere? I dont see it in the config.

EDIT: nevermind I see you're referring to the github workflow.

@brandonwillard could you check this again. The test failure is the unrelated DisconnectedInputError that was mentioned earlier.
