# ai-agent-book vs skypilot

ai-agent-book and skypilot share 5 technologies: FastAPI, psycopg2-binary, Postgres, lxml, and Tailwind CSS. Both are written in Python.

- [bojieli/ai-agent-book](https://seerepo.com/r/bojieli/ai-agent-book): 《深入理解 AI Agent：设计原理与工程实践》（李博杰 著）开源主仓库：全书正文、编译版 PDF 与按章配套代码
- [skypilot-org/skypilot](https://seerepo.com/r/skypilot-org/skypilot): The AI Compute Platform for frontier teams. SkyPilot turns fragmented AI compute into one AI supercomputer, so frontier AI teams build custom intelligence faster.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
