Show HN: Sentinel – open-source QA agent that reads your code before it clicks

Hey guys, we built something interesting that we're using for testing / QA with our own products and it's proving to be quite helpful. MIT License - https://github.com/Simbastack-hq/sentinel Blog announcement - https://blog.simbastack.com/announcing-sentinel/ PS - Resubmitting this ShowHN since when I posted this yesterday, I completely forgot to make the repo visibility public.
