I let Google's Jules AI agent into my code repo and it did four hours of work in an instant

I just added an entire new feature to my software, including UI and functionality, just by typing four paragraphs of instructions. I have screenshots, and I'll try to make sense of it in this article. I can't tell if we're living in the future or we've just descended to a new plane of hell (or both). Let's take a step back. Google's Jules is the latest in a flood of new coding agents released just this week. I wrote about OpenAI Codex and Microsoft's GitHub Copilot Coding Agent at the beginning of the week, and ZDNET's Webb Wright wrote about Google's Jules. All of these coding agents will perform coding operations on a GitHub repository.
