I watched someone build a full AI app in minutes. Then the API errored and they had no idea where to look. They had never seen a raw API response. They asked the AI to fix it, stacked patches until the errors eventually killed the app. They had built something they couldn't debug.

I used to be in the same spot. So I stripped it all down to raw API calls.

There's barely anything there.

Memory? A list you resend every time. Tool calling? The model returns JSON saying "call this function." You call it. That's "AI agents." RAG? Search docs, paste into prompt, ask.

Oversimplification? Maybe. But the fundamentals never stop being useful, no matter whatever advanced tool it's used.
