fellow 0.1.0

Fellow CLI tool is a command line development assistant

Project Description

Fellow is a command-line AI assistant built by developers, for developers.

Unlike most AI tools that just suggest code, Fellow goes further: it executes tasks for you. It reasons step-by-step, picks commands from a plugin system, and performs actions like editing files, generating content, or writing tests — all autonomously.

Fellow was born from a simple insight: copy-pasting between ChatGPT and your editor breaks flow. What if the AI could access your codebase directly and decide what to do?

It’s a lightweight but powerful sandbox for building the tools you wish existed — and it's still evolving. If you're a developer who wants more doing and less prompting, Fellow might just be the tool you’ve been waiting for.

Installation

Make sure you have Python installed on your system. Then install Fellow via pip:

pip install fellow

Quick Start

Fellow can use the OpenAI API, so you need to provide your API key. The easiest way is:

fellow add-secret OPENAI_API_KEY your_openai_api_key

Then you're ready to go. For example, to ask Fellow to write a README file:

fellow --task "write a readme file for this Python project"

Customization

Fellow is built to be extensible. You can customize:

• Commands – add your own automation logic or override existing ones. Learn more in the Custom Commands documentation

• Clients – integrate with different AI backends like built-in OpenAI or Gemini. Or create your own client. Learn more in the Custom Clients documentation

• Policies – control Fellow’s behavior in specific situations to ensure safe and predictable AI use. Custom Policies documentation
