Is this closer to an early AI OS, or just an AI agent?

Hello. I am writing because I want to hear opinions. I am a non-English speaker, so I got help from AI for the English expression. I am building a personal AI system only with my phone (Android) and Termux, without a PC. I open several AI chat windows and make them collaborate indirectly by copy and paste, and almost every day I keep growing the structure little by little. Before, I just called it “garlic-agent.” But as the project became bigger, I started to think maybe this is getting closer to an early AI OS rather than only a simple AI agent. Of course, I do not mean OS in the same sense as a normal operating system. But inside, it is moving more and more like one small operating environment. The rough structure is like this. It runs on a phone (Android) with Termux. There is a web UI for conversation. I connect several LLM providers. There is a tool calling structure such as read, search, exec, write, patch, garlic, and others. There is knowledge.db with RAG search for documents.
