Nanocode is a minimal Claude Code alternative in a single Python file that provides an agentic coding loop with file and shell tools. It runs with zero external dependencies and is easy to inspect, customize, and extend for AI-assisted development workflows.

What to expect from an ideal product
- Drop the single Python file into your project folder and run it directly without installing any packages or dependencies
- Connect to Claude's API by adding your credentials and let the AI agent automatically read, write, and modify files in your codebase
- Enable shell command execution so the agent can run tests, install packages, git operations, and other terminal tasks during development
- Customize the coding loop by editing the Python file to add your own tools, prompts, or workflow steps that match your project needs
- Set up continuous iteration where the agent analyzes code, makes changes, runs tests, and refines based on results until tasks are complete
