This comment - and many others - misses the OP's original point: what are tools? Do you mean my laptop, and a pen and paper? What's an agent? I.D.E.? none of this is part of the vocabulary or context of someone who has never built things with a computer, let alone AI. Years ago I had a neighbor who was trying to learn how to use their computer; they complained that the book they were using was only telling them all the DOS and none of the DON'TS. This is were most people start.
