This is my definitive Claude Code Advanced Course for people who already understand the foundations and want to level up fast—no fluff. I use Claude Code and AI agents in my own business every day (we’re talking $4M+/year profit), and in this course I show you the exact systems I use to build bigger projects, save tokens, and get higher-quality outputs with less back-and-forth. We start with an advanced breakdown of CLAUDE.md and system prompts—how to structure them so they actually improve quality (it’s simpler than you think). I explain CLAUDE.md as four things: knowledge compression, your preferences/conventions, a declaration of capabilities (so Claude stops pretending it “can’t” do things), and a log of failures/successes that cuts out wasted solution space. Then I show how to split prompts into global vs local scope, and the workflow loops I use to continuously update both. From there, we move into agent harnesses, agent teams for extreme task parallelization, skills/subagents for organization, Karpathy-style autoresearch, browser automation (computer use vs browser use), performance fluctuations + alternatives, workspace organization for client work, security (including auto-mode and OAuth), and where I think Claude Code is going next.
