Hermes Book

What Hermes Book does

Hermes Book, titled Hermes Agent 源码与设计, is a Chinese-language book based on the v0.8.0 source of Hermes Agent. Its organizing question is what engineering problems a self-improving personal agent has to solve, and it weaves product ideas, architecture choices and source implementation together. Four design bets frame the analysis: a learning loop that creates skills and persists knowledge, a CLI-first approach, personal long-term memory and user modeling, and the ability to run anywhere from a $5 VPS to a GPU cluster.

The 23 chapters and four appendices are grouped into seven parts covering the request journey, the AIAgent core, the prompt system, the tool system, skills, subagent delegation, SessionDB, memory providers, context compression, CLI and TUI, gateway, scheduling, execution backends, configuration, model abstraction, concurrency, fault tolerance and testing. The README suggests four reading paths: full-stack understanding, building a similar product, stability engineering, and memory and learning. It assumes a reader with Python, LLM agent and CLI or server engineering background, and the book can be read online or built locally with mdbook.
