Q: A developer keeps merging code to the `main` branch that breaks the build because they forgot to run the code formatter (`black` or `prettier`) locally. How do you force this compliance automatically?
The SRE/DevOps approach is to "Shift Left" and employ automation before the code ever leaves the developer's laptop.

Production Solution & Architecture
The SRE/DevOps approach is to "Shift Left" and employ automation before the code ever leaves the developer's laptop. I would implement a Pre-commit Hook. Using a framework like pre-commit (Python) or husky (Node), I configure a .pre-commit-config.yaml in the repo. When the developer types git commit, the hook automatically intercepts the action and runs the code formatter. If the format violates rules, the commit is rejected locally before it can even be pushed to the remote repository.
