    You drop an AI agent into your real codebase and it produces garbage. Wrong style, subtle bugs, side effects everywhere. The problem isn't the model. Your codebase isn't ready for AI. Think of it like handing off a biathlon relay with no map of the course 🥇🧵👇

    I finally published Burla, a .NET mocking library I have been rewriting for months while pressure-testing models, local setups, and agentic coding workflows. I needed a real project, not one more opinion about AI. Built with LLMs in the loop, for the LLM era. Thread below. 🧵👇

    If you're still defaulting to Claude Opus in GitHub Copilot, you're probably paying a hype tax. 🧵👇 Opus 4.6 = 3x requests. Opus 4.7 = 7.5x. GPT-5.4 = 1x, even with xhigh reasoning in VS Code. I do not see a quality gap remotely close to that.
