This module writes one working custom tool + stack/tools.md updated, which 4 later modules read. It is part of the paid course.
You give your agent one capability it did not have yesterday, and you use it on your real task today. First you work out which of three problems you actually have, because a missing fact, a missing reach, and a missing permission look identical from the outside and have completely different answers. Then you build the smallest thing that closes the gap, describe it so it gets picked at the right moment, and write down what it says when it cannot do the job.
Twelve modules, thirteen files. From typing into a box to a working setup you own — no technical background assumed.
Build AI that acts. Sixteen modules, fourteen files, two tracks, and the rules written down before anything runs.
Twenty-eight modules end to end, in the order they were meant to be read.
After you pay: a sign-in link lands in that inbox and the first paid module opens. Usually under a minute.
