是什么让 Claude Code 如此出色（以及如何在你的 agent 中复现这种魔力）！？

Claude Code is the most delightful AI agent/workflow I have used so far. Not only does it make targeted edits or vibe coding throwaway tools less annoying, using Claude Code makes me happy. It has enough autonomy to do interesting things, while not inducing a jarring loss of control like some other tools do. Of course most of the heavy lifting is done by the new Claude 4 model (especially interleaved thinking). But I find Claude Code objectively less annoying to use compared to Cursor, or Github Copilot agents even with the same underlying model! What makes it so damn good? If you're reading this and nodding along, I'm going to try and provide some answers.

Claude Code 是我迄今为止用过最令人愉悦的 AI agent/workflow。它不仅让有针对性的编辑或 vibe coding 一次性工具变得不那么烦人，使用 Claude Code 本身也让我开心。它拥有足够的自主性去做有趣的事情，同时又不会像某些工具那样带来令人不适的失控感。当然，大部分重活都是由新的 Claude 4 模型（尤其是交错思考）完成的。但我发现，即使底层模型相同，Claude Code 客观上也比 Cursor 或 Github Copilot agents 更不烦人！它到底为什么这么棒？如果你读到这儿并频频点头，我将尝试给出一些答案。

Note: This is not a blogpost with Claude Code's architecture dump (there are some good ones out there). This blogpost is meant to be a guide for building delightful LLM agents, based on my own experience using and tinkering with Claude Code over the last few months (and all the logs we intercepted and analyzed). You can find prompts and tools in the Appendix section. This post is ~2k words long, so strap in! If you're looking for some quick takeaways, the TL;DR section is a good place to start.

注意：这不是一篇关于 Claude Code 架构详解的博客（网上已经有一些不错的文章）。这篇博客旨在基于我过去几个月使用和折腾 Claude Code 的经验（以及我们拦截和分析的所有日志），为你提供构建令人愉悦的 LLM agent 的指南。你可以在附录部分找到 prompts 和工具。这篇文章大约 2k 字，请系好安全带！如果你想快速了解要点，TL;DR 部分是个不错的起点。

Claude Code (CC) feels great to use, because it just simply works. CC has been crafted with a fundamental understanding of what the LLM is good at and what it is terrible at. Its prompts and tools cover for the model's stupidity and help it shine in its wheelhouse. The control loop is extremely simple to follow an...
