A tool like pre-commit really helps here: it'll run against the staged files, before committing. Your CI tool really ought to be testing the commit too, at which point having a clean commit locally isn't necessary for correctness, only for avoiding needing to re-do your work.

It's really important to catch bugs early, because it's a lot more expensive to fix them later -- even if only as late as in CI before merging.
