This feels like a pretty deceptive article title. At the end, he does say:

"What We Built vs. Production Tools This is about 200 lines. Production tools like Claude Code add:

Better error handling and fallback behaviors Streaming responses for better UX Smarter context management (summarizing long files, etc.) More tools (run commands, search codebase, etc.) Approval workflows for destructive operations

But the core loop? It’s exactly what we built here. The LLM decides what to do, your code executes it, results flow back. That’s the whole architecture."

But where's the actual test cases of the performance of his little bit of code vs. Claude Code? Is the core of Claude Code really just what he wrote (he boldly asserts 'exactly what we built here')? Where's the empirical proof?
