A FULL CODE AGENT IN 200 LINES—HERE'S HOW

Summary from the TLDR Web Dev newsletter

A minimal code agent, dubbed "nano-claude-code" in this article, can be built in just 200 lines of code using JavaScript and Bun. The agent uses tools like reading and writing files and executing bash commands to interact with the local filesystem. The core of the agent is a while loop that interacts with a large language model to plan and execute coding tasks based on user prompts and tool availability.
