Google engineer with 11 years of experience automated 80% of his work using Claude Code and a simple dotnet app.
Now he works 2-3 hours a day instead of 8 and chills the rest of the time while the system runs itself making $28,000 in passive income.
Here's what he knows that you don't.
## Part 1 - CLAUDE.md by Karpathy's rules
Andrej Karpathy - one of the most influential AI researchers in the world - documented the most common mistakes LLMs make when writing code: over-engineering, ignoring existing patterns, adding dependencies nobody asked for.
Someone took these observations and turned them into a single CLAUDE.md file.

The idea is simple: if mistakes are predictable — they can be prevented with the right instructions. One markdown file in the repo gives Claude Code a structured set of behavioral rules for the entire project.
Four principles inside:
Think Before Coding → stops wrong assumptions and missed tradeoffs
Simplicity First → stops over-engineering and bloated abstractions
Surgical Changes → stops touching code nobody asked to touch
Goal-Driven Execution → tests first, verified success criteriaNo frameworks. No complex tooling. One file that changes Claude's behavior at the project level.
Real difference:
Without CLAUDE.md: Claude breaks conventions in ~40% of cases
With Karpathy CLAUDE.md: violations drop to ~3%
Setup time: 5 minutesCommand that auto-generates your own CLAUDE.md:
claude -p "Read the entire project and create a CLAUDE.md based on:
Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution.
Adapt to the real architecture you see." --allowedTools Bash,Write,ReadReplaces: Claude that over-engineers simple tasks, adds dependencies nobody asked for and touches files it shouldn't.
