Mini Coding Agent

What is Mini Coding Agent?

Mini Coding Agent is a small, standalone coding agent written in Python by Sebastian Raschka and published on GitHub as rasbt/mini-coding-agent. It accompanies his article Components of A Coding Agent, which explains how tools, memory and repository context turn a language model into something that can work on code, the way harnesses such as Claude Code and Codex CLI do. The project implements a minimal agent loop: it collects a snapshot of your workspace, builds a stable prompt with turn state, exposes structured tools, asks for approval before risky ones, saves a transcript and memory, and supports bounded delegation to sub-agents. The model backend is currently based on Ollama, so it runs against local models on your own machine. It is meant as a readable teaching reference rather than a production tool, and it is free and open source under the Apache-2.0 license. There is no pricing, and model costs are limited to your own hardware and electricity.

Use cases

• Learn how a coding agent harness works
• Read a minimal agent loop in Python
• Run a coding agent on local models
• Experiment with tools and approvals
• Prototype your own agent harness
• Study memory and transcript handling

Who it's for

• Developers learning about agents
• AI and machine learning students
• Researchers and educators
• Hobbyists running local models

Why use Mini Coding Agent

• The code is small enough to read end to end, which makes agent internals easier to understand.
• It pairs with a detailed article that explains each building block of a coding agent.
• Running against local models through Ollama means no per-token API fees and no code leaving your machine.
• Because it is Apache-2.0 licensed, you can fork it and change the harness however you like.
• Risky tools require approval, so you can see how permission handling fits into the loop.

Mini Coding Agent features

• Minimal local agent loop written in Python
• Workspace snapshot collection for repo context
• Stable prompt with turn state
• Structured tools for reading and editing
• Approval step before risky tools run
• Saved transcript and memory
• Bounded delegation to sub-agents
• Ollama model backend for local models
• Apache-2.0 license

How to get started with Mini Coding Agent

1. Clone the rasbt/mini-coding-agent repository from GitHub and read the accompanying article.
2. Install and run Ollama with a local model of your choice.
3. Start the agent in a project folder so it can collect a snapshot of the workspace.
4. Give it a coding task; it calls structured tools and asks approval before risky ones.
5. Review the saved transcript and memory, and modify the Python code to experiment.

Mini Coding Agent limitations

• Educational scale rather than a full production agent
• Model backend is currently based on Ollama
• Not a replacement for full tools such as Claude Code or Codex CLI
• Small local models can limit quality
