From the creator

Download the FREE Claude Code for Marketing Guide from HubSpot! https://clickhubspot.com/4388d4 Everyone uses Claude Code, but almost nobody knows what's actually happening under the hood. So I built my own version of it from scratch to find out. In this video I break down how coding agents like Claude Code really work: the agent loop, how the model decides which tools to call, how it reads and edits your files, runs terminal commands, and manages context so it doesn't forget what it's doing. Then I put the pieces together into a working mini Claude Code you can build yourself. Want to make real money with coding?
