Frequently asked questions about Butterfish

What is Butterfish and what does it do?

Butterfish is a command-line shell tool that integrates AI assistance into your terminal using OpenAI models. It allows users to ask contextual questions, debug commands, generate shell commands, and perform tasks directly from the command line without leaving their workflow.

Who is Butterfish designed for?

Butterfish is designed for developers, system administrators, and users who work extensively in the command line and want AI-powered assistance without disrupting their workflow. It is particularly useful for those familiar with shells like bash or zsh.

How does Butterfish integrate with my existing shell?

Butterfish wraps your existing shell (tested with zsh and bash) rather than replacing it. You invoke it with a command like 'butterfish shell' or a configured alias, and it adds AI prompting capabilities while preserving your usual shell behavior.

What kind of AI assistance does Butterfish provide?

Butterfish allows you to start commands with a capital letter to prompt the AI, such as asking for explanations, debugging failed commands, generating shell commands, or even general questions like recipes. It uses your shell history as context for more relevant responses.

Can I customize the AI prompts in Butterfish?

Yes, Butterfish offers prompt transparency and configurability. You can view raw AI requests and responses in verbose mode and edit the prompts by modifying the configuration file located at ~/.config/butterfish/prompts.yaml.

How do I get started with Butterfish?

To get started, install Butterfish via Homebrew on macOS or using Go on Linux. The first run will prompt you to paste an OpenAI API key, which is stored securely in a configuration file. You can then use it by running 'butterfish shell' or a configured alias.
