A tutorial project that walks through building a minimal 600-line TypeScript coding agent (nano-pi) modeled on the production-grade pi agent. It pairs an article with an interactive website showing source code and execution traces, covering the LLM streaming layer, agent loop, and file/bash tools.

Use cases

• learn how to build an AI coding agent from scratch
• understand agent loops and tool calling in TypeScript
• study how the pi agent architecture works
• build a minimal LLM agent that reads files and runs bash
• teach myself LLM streaming and SSE parsing
• follow a step-by-step coding agent tutorial

When to choose

• you want to understand agent internals rather than use a production tool
• you prefer learning by building a tiny implementation
• you want a readable TypeScript codebase for agent loops and tool calling

When to avoid

• you need a production-ready coding agent with multi-provider support
• you need extensions, session branching, or token compaction features
• you want a framework to build applications on rather than a teaching resource
