# Karpathy-Inspired Claude Code Guidelines > Check out my new project [Multica](https://github.com/multica-ai/multica) — an open-source platform for running and managing coding agents with reusable skills. > > Follow me on X: [https://x.com/jiayuan_jy](https://x.com/jiayuan_jy) A single `CLAUDE.md` file to improve Claude Code behavior, derived from [Andrej Karpathy's observations](https://x.com/karpathy/status/2015883857489522876) on LLM coding pitfalls. English | [简体中文](./README.zh.md) ## The Problems From Andrej's post: > "The models make wrong assumptions on your behalf and just run along with them without checking. They don't manage their confusion, don't seek clarifications, don't surface inconsistencies, don't present tradeoffs, don't push back when they should." > "They really like to overcomplicate code and APIs, bloat abstractions, don't clean up dead code... implement a bloated construction over 1000 lines when 100 would do." > "They still sometimes change/remove comments and code they don't sufficiently understand as side effects, even if orthogonal to the task."
