About the author, Guo Li (leeguoo), and these bilingual field notes.
I'm Guo Li (郭立, English name Leo, online as leeguoo), a full-stack developer.
I've written code at Qunar (去哪儿网) and Zhihu (知乎), and these days I spend most of my time on open-source tools and writing — mostly small CLIs and AI-agent skills that plug into Claude Code / Codex / your terminal. A few of them: claude-code-usage-bar, chatgpt-imagegen, wechat-use, and Mailbox.
This site is my technical blog: reverse engineering, AI agents, building things on the web, and notes from everyday hacking. Bilingual, written for people who also like to build.
