Overview

thndrs is a minimal, LLM powered pair programmer.

It provides a terminal UI for chatting with an LLM and tools to read and modify code based on context/project guidance you provide. Like pi, it’s meant to stay focused on reading and writing code with the essentials. You provide it with the command-line tools you need for your projects.
