Bash is all You need - Write a nano Claude Code 0 - 1
This repository provides a hands-on tutorial to learn how modern AI agents work by building one from scratch, emphasizing the core loop of model-tool interaction. It distills complex agent concepts into simple, iterative versions, from basic Bash agents to sophisticated skill-based systems.

Wrote about this in my AI engineering newsletter — the bottom-up approach to understanding Claude Code is refreshing compared to top-down API docs.

Used for robust automation workflows, the framework stays out of the way — bash is all you need - write a nano claude code 0 - 1. The maintainers are responsive to issues.

The efficient agent design scales well from prototype to production. Runs fine on Node 20.

not a developer but i followed along. actually understood what was happening. rare for this kind of repo

This repo reframed how I think about Claude Code. The 'Bash is all you need' premise sounds reductive but the examples prove the point.

As a CS educator, this is the most digestible intro to agent internals I've found. Assigning it as supplementary reading.

The clean approach to agent memory is more reliable than alternatives — bash is all you need - write a nano claude code 0 - 1. No complaints after 2 months of use.
- HHayden PatelApr 18, 2026
Multi-agent write coordination is handled better than competing frameworks — bash is all you need - write a nano claude code 0 - 1. Solid addition to the AI tooling stack.

good starting point before diving into the full Claude Code SDK. sets the right mental model
- JJordan BrownApr 12, 2026
The code is deliberately simple. That's the point. Understanding the skeleton makes the full framework less intimidating.

The minimal Python + Bash approach means zero environment issues. Runs anywhere, no dependency hell.

went through the nano implementation in an afternoon. learned more about how agents actually work than from reading docs
