Mini pi

A minimal coding agent in python.

For the past month I have been exploring how to create an agent from scratch without frameworks, and I have also been digging into how to do evaluations. You can see the experiment artifacts here: https://gitlab.com/nik-55/llm-systems

Based on what I learned there, I want to build a harness that works and stays small. The goal is to keep it readable. Currently it follows the tau architecture

The current state:

No AI slop, and around 1700 lines of code
Streaming responses
4 tools (read, write, bash, edit)
Sandboxing using bwrap on Linux
Interruption handling
Session persistence
A few basic commands (/clear, /session, /resume, /exit)
REPL only for now

Setup

clone the repo
install the tool using uv tool install .
export the environment variables:

export OPENAI_API_KEY=
export OPENAI_BASE_URL=
export MODEL=

run minipi from any of your project
