A comprehensive Chinese technical guide ("御舆") that deconstructs AI Agent architecture, specifically analyzing Claude Code's design patterns including conversation loops, tool permission pipelines, context compression, and the Agent Harness runtime framework. Provides a transferable mental model for building production-grade agent systems across different frameworks without relying on prompt engineering tutorials.

In-depth technical analysis of Claude Code's source architecture, covering the agent loop, context engineering, tool system, and production-grade error recovery strategies. Includes a companion project (Claude Code From Scratch) with ~4000 lines of TypeScript/Python and 11-chapter tutorial for building your own AI programming agent from scratch.
