The tutorial walks through creating a CLI tool that can autonomously read, write, and execute Python files within a working directory. It covers essential concepts like LLM function calling, system prompts, token management, and building feedback loops that allow the agent to iteratively solve coding tasks. The project demonstrates how AI code editors like Cursor and Claude Code work under the hood by implementing file operations, Python execution, and conversational context management. ## Full article daily.dev links to this article rather than hosting it.
