Shell scripts in Arduino tooling projects are formatted according to the style implemented by the shfmt formatting tool.
In addition to standalone script files, significant quantities of complex shell code is also found in the asset tasks and workflows. shfmt can not be used to format this code (both due to the fact it is in the form of strings in YAML documents, and due to the fact that it is actually templates of shell code (making use of the templating features of Task and GitHub Actions) rather than complete shell code). However, it still makes sense to align the formatting of this code with the standardized shell code style where doing so is feasible.
