This repository is a free downloadable book about Hermes Agent, an open-source AI Agent framework released by Nous Research in early 2026. The book is available in both English and Chinese as a PDF, and it is part of a series called the Orange Book series, which produces practical guides on AI tools. Hermes Agent is described in the book as taking a different approach from tools like Claude Code or Cursor. Its distinguishing features are a built-in self-improving learning loop, a three-layer memory system, and the ability to automatically create and update its own Skills over time. The book positions this as the first tool to turn a set of theoretical AI agent design principles (called Harness Engineering) into a working product. The book is organized into 17 chapters across 5 parts. The first two parts cover the concepts behind the framework and its core mechanisms, including how the learning loop, memory, and tool system work. The middle section is hands-on, walking through installation, having a first conversation, setting it up across different platforms, and customizing its behavior. The final sections cover real-world use cases such as building a personal knowledge assistant or automating development tasks, and close with a comparison against other agent tools and a discussion of the limits of self-improving systems. The intended audience is developers and AI enthusiasts who have already used tools like Cursor or Claude Code and want to understand how Hermes Agent compares. No prior experience with Hermes Agent is assumed. The author, known as HuaShu, is an independent developer and AI content creator who describes building products entirely using AI tools.
