This repository is a comprehensive guide (Orange Book) for Hermes Agent, an open-source AI agent framework by Nous Research. It contains PDFs of the second edition (v0.16.0), screenshots, and a single Python utility script for adding PDF bookmarks. The codebase is minimal: there is no application, library, or data pipeline. The primary value is the book's content, not the software. The Python script (tools/add_toc_bookmarks.py) is a well-documented, self-contained tool that uses pypdf to scan PDFs for section headers and automatically generates a hierarchical outline. The project is clearly organized with bilingual READMEs, an errata section, and a MIT license. While the repository is not a reusable software project in the traditional sense, the bookmark utility is a practical component that could be extracted for similar PDF processing tasks. Overall, the repository serves its purpose as educational documentation rather than a functional application.
