zero2Agent
A Chinese-language agent-engineering tutorial site for programmers, covering agent frameworks, coding-agent internals and production deployment, alongside a downloadable book of nearly 800 Agent interview questions for Chinese tech-company recruiting.
zero2Agent is a tutorial repository aimed at programmers who already write code and use AI tools but have not yet built agent systems from first principles, organized into modules covering agent fundamentals, LangGraph, the OpenAI, Google and Anthropic agent SDKs, framework surveys of tools such as AgentScope, Mastra and AutoGen, and deep dives into OpenClaw, Claude Code, DeepSeek Harness, Pi Coding Agent and Codex CLI internals, plus modules on agent training with supervised fine-tuning and reinforcement learning and applied deployment. A capstone project walks through building an interview-diagnosis agent end to end.
It includes a downloadable PDF book, licensed under Creative Commons BY-NC-SA 4.0, covering 17 assessment dimensions across nearly 760 Agent and AI interview questions drawn from real interviews at large Chinese technology companies, sorted by how often each topic appears and contrasting a novice answer with an expert answer for comparison.
The material is published as an online book on GitHub Pages, with 131 articles across 12 completed modules and one still being updated at the time of writing.
