What I mean is if I were to add dependency or simply update the dependency

What type do I choose (feat,fix,refactor,etc)?

Esp since commitizen default list of choices does not contain "chore"

First, you don't need to use cz commit, you can just do git commit -am "chore: add new dependency", but it will be ignored by the bump`.

For choosing a type, is up to you, there are 2 philosophies:

1. Bump always: this means you'd use something like fix and feat all the time. When you install a new dependency it could be a dependency that fixes something. This is just simpler to think about: new commits -> new bump
2. Bump sometimes: some dependencies may introduce fixes, or security updates, others might be just dev dependencies, so it's not necessary. In this case, you choose to ignore some changes, because they don't require a bump, but at the risk of making a mistake of pushing something that should've been a bump. I've had this a lot of times, specially with dependabot, which pushes a build for dependencies, and then people ask me if I can release the version manually, because they need either that new dep, or because the constrain in dependencies is a problem for them

I agree that I don't always have to use cz commit

But I like how cz makes it clear with a menu for me to choose

So as much as I can, I like to keep within the menu

That's my motivation for this discussion thread

No problem, also don't be too rigid, if with time this doesn't work for you, evaluate again, and create new guidelines.

Good luck!
