Special Token Magic in Transformers

A comprehensive technical book about special tokens in transformer architectures, created as a demonstration of AI-assisted book authoring using Claude CLI agents.

🤖 AI-Generated Content

This book is a demonstration of AI-powered technical writing using Claude CLI with the AGENTS.md framework. The entire content was generated with minimal human intervention - primarily high-level guidance and iterative refinement requests.

Creation Process

  1. Agent-Driven Architecture: Used specialized Claude CLI agents to generate structured, technical content
  2. Iterative Development: Book was built chapter by chapter through conversational prompts
  3. Technical Accuracy: AI agents maintained consistency across mathematical notation, code examples, and technical concepts
  4. Professional Formatting: Automated LaTeX formatting, bibliography management, and document structure

What Was AI-Generated

  • Complete manuscript (321 pages)
  • Technical content including algorithms, code examples, and mathematical formulations
  • Document structure with proper LaTeX formatting
  • Bibliography with proper citations
  • Figures and diagrams using TikZ
  • Professional typography with Times font and proper spacing

Human Input

  • 🎯 Topic direction: "Write a book about special tokens in transformers"
  • 🎯 Structural guidance: Chapter organization and content depth
  • 🎯 Quality control: Formatting adjustments and compilation fixes
  • 🎯 Publishing decisions: Font choices, layout preferences

📖 Book Content

  • Graphics: TikZ for technical diagrams and attention visualizations
  • Bibliography: BibLaTeX with author-year citation style
  • Build System: Standard LaTeX compilation pipeline

📊 Statistics

  • Pages: 321
  • Chapters: 10 complete + 4 planned
  • Code Examples: 50+ Python implementations
  • Figures: Custom TikZ diagrams and attention visualizations
  • Generation Time: ~2 hours of interactive AI assistance

🚀 Compilation

# Compile the book
pdflatex main.tex
biber main
pdflatex main.tex

# Or use the complete build process
make  # if Makefile exists

🎯 Demonstration Value

This project showcases:

  1. AI Capability: Complex technical content generation with consistency
  2. Agent Architecture: Structured approach to large document creation
  3. Minimal Supervision: Human role limited to high-level guidance
  4. Professional Quality: Publication-ready formatting and presentation
  5. Iterative Refinement: AI's ability to incorporate feedback and improve

📝 AGENTS.md Framework

This book was created using an AGENTS.md framework that defines specialized roles for different aspects of technical writing. The agent definitions are available at: https://github.com/hfgong/book-writer-agent

The framework includes specialized agents for:

  • Content Structuring Agent: Chapter organization and flow
  • Technical Writing Agent: Deep technical explanations and examples
  • Code Generation Agent: Python implementations and algorithms
  • LaTeX Formatting Agent: Professional document preparation
  • Quality Assurance Agent: Consistency and accuracy verification

🔍 Future Work

This demonstrates the potential for:

  • Automated Technical Documentation: Generate comprehensive guides from specifications
  • Educational Content Creation: Produce textbooks and learning materials at scale
  • Research Paper Assistance: Structure and draft technical papers
  • Corporate Documentation: Create training materials and technical manuals

⚠️ Disclaimer

This content is AI-generated for demonstration purposes. While technically accurate, readers should verify information for production use and consult primary sources for critical applications.
