My experiments so far indicate that modifying the verbosity significantly reduces the output quality. This isn't too surprising since a good commit message should be fairly concise.

Committing my work to the branch in case we decide to revisit this later.

Per conversation with @rahulmysore23, re-opening for further investigation. Maybe just a max_length flag?

@rahulmysore23 - Following up on our conversation, look at the branch for this ticket.

If you look in /magic-commit/templates, I was experimenting with using different few-shot prompting based on the user's requested verbosity. For example, examples_verb_1.jinja gives the shortest possible commit messages.
