I am working on a development harness using AI agents. There are plenty on the market, but I wanted something that encourages builders to build commercial solutions, not small POCs. In my experience, most stop at demos and betas. The name is funny, I know, but it has a significant meaning for me. When I started using AI, even with excellent prompt design, it always took me down the happy path. Most AI is designed to satisfy the prompt without really questioning the quality of what it delivers. And then the bad surprises start showing up. A commercial application needs much more than a prompt can deliver: security, usability, deployment, maintenance, users management, cloud, web or native design, and of course quality. It takes a full stack to build one. After months of trial and error, I reached this verdict: -You need a watcher to keep the AI from hallucinating and drifting. And facilitating the route if issues appears during developments and tests. -Never let the developer agent test its own work and claim it's done. -Build a reviewer from a different company's AI to refute the developer's claims and build its own tests. -Let the user be manage the final delivery gate I also built the plumbing to keep the context small and make it easy for non-coders. You describe what you want and approve the requirements. Then the agents build and test it on the machine the software is meant for, with no one needed until you review the delivered solution and approve it. It builds web or native software for Linux, Windows and Mac. It's open source: https://github.com/nomorehappypath/nomorehappypath
