Question 1
The article compares an API to what?
The article describes an API as a door. Every service has one. You knock on it with a structured request and get a structured response back.
Question 2
What are the two raw materials that go into every AI system?
Intent (what you want) and context (the background that shapes the output). These two inputs drive everything downstream.
Question 3
Why does the article say a spec should NOT name specific tools or vendors?
Tools change. The system design persists. A spec describes what the system does, not which vendor runs it. That's the whole point.
Question 4
What does the article call the pattern of "draft, review, revise"?
That's a loop. Draft, review, revise. The article calls loops the most important concept in the whole piece.
Question 5
According to the article, what does a human always provide that AI cannot?
The human provides the intent. Always. AI is good at how. It is terrible at what.
