Product Overview: Butterfish Shell
Introduction
Butterfish Shell is an innovative command-line tool designed to integrate AI capabilities, specifically using Large Language Models (LLMs), into your existing shell environment. This tool is particularly useful for individuals who work extensively from the command line, such as developers, system administrators, and power users.
What it Does
Butterfish Shell enhances your bash or zsh shell by adding AI-powered prompting, automation, and contextual assistance. It acts as a “shell wrapper,” meaning it runs alongside your existing shell without requiring any changes to your current setup. This integration allows users to leverage the capabilities of LLMs, such as OpenAI’s GPT models, directly within their terminal.
Key Features and Functionality
Shell Integration
- Butterfish Shell wraps around your existing shell (bash or zsh), intercepting input and output to provide AI-driven features without disrupting your normal workflow.
Contextual AI Assistance
- Users can trigger AI assistance by starting a command with a capital letter. For example, typing “How do I recursively find local .py files?” will send the prompt to the LLM, which then provides a response based on the shell history and context.
Goal Mode
- The tool includes a “Goal Mode” where the AI acts as an agent to execute commands to achieve a specified goal. This can be activated by starting a command with “, and it allows the AI to execute commands and debug problems without user confirmation if prefixed with `!!`.
Autocomplete and Suggestions
- Butterfish Shell offers AI-powered autocomplete for shell commands. As you type, the AI can suggest complete commands based on your shell history and current context, which can be applied by pressing the `Tab` key.
Debugging and Error Resolution
- Users can ask contextual questions like “Why did that command fail?” and the AI will analyze the previous commands and errors to provide an explanation.
Customizable Prompts
- The tool allows for transparent and configurable prompts. Users can view and edit the raw AI requests and responses, and customize prompts in the `~/.config/butterfish/prompts.yaml` file.
Model Selection
- Butterfish Shell supports multiple LLM models, including GPT-3.5-turbo and GPT-4, allowing users to select the model that best suits their needs.
Additional Utilities
- Beyond shell integration, Butterfish also includes CLI utilities for prompting, generating commands, summarizing text, and managing embeddings of local files.
User Experience
Butterfish Shell provides a seamless and intuitive user experience by integrating AI assistance directly into the command line. This approach eliminates the need for copy-pasting or switching between different applications, making it a powerful tool for enhancing productivity and efficiency.
Conclusion
Butterfish Shell is a groundbreaking tool that brings the power of AI to the command line, making it an indispensable asset for anyone who relies heavily on shell commands. Its ability to provide contextual assistance, automate tasks, and offer customizable prompts makes it a versatile and user-friendly solution for integrating AI into daily workflows.
