Thanks for your work on this!

If we are going to merge this, we should create a dedicated travis-ci account for snapcraft-desktop-helpers, or maybe re-use an existing one used by other ubuntu projects (is there one?).

I'm not familiar with pre-commit, do we really need this framework to just run shellcheck on the shell scripts? Or do you envision that there are other useful existing pre-commit hooks that we could add to the CI logic in the future?

Oops I did not notice that the badge is actually bound with my forked repo, I've dropped the badge commit.

I once used manually crafted scripts to check the bash scripts, but pre-commit surpasses all my expectations so recently I dropped all of them in favor of pre-commit.

Please check out the Supported Hooks, I'm sure there are many hooks we can use with the project.
