Motivation for Writing As an active user of AI development tools, I have seamlessly integrated Agent Skills into my daily workflows using Claude Code, Gemini CLI, and Antigravity. However, despite leveraging them regularly, I realized that I had been treating them somewhat as a black box. I lacked a deep, granular understanding of their internal working principles—specifically, the internal execution steps and orchestration occurring within the Generative AI models. To bridge this gap, I decided to thoroughly investigate the architecture of Agent Skills. I believe that documenting and sharing these insights will not only solidify my own understanding but also provide immense value to other developers navigating the complexities of scalable AI agents. Abstract As Large Language Models evolve into autonomous agents, developers encounter Tool Space Interference (TSI)—context bloat caused by excessive tools that degrades reasoning.…
