Butterfish: AI-Enhanced Command Line Shell with GPT Integration and Goal Mode
Overview
Butterfish is an open-source CLI tool that enhances shell interaction by integrating GPT models, primarily GPT-4 Turbo, into your command line environment. It wraps your existing shell (bash, zsh) to provide AI prompting directly from the terminal, enabling features like contextual command suggestions, autocomplete, and chat-like interactions without copying and pasting. Users can start prompts with a capital letter to ask questions, debug commands, or generate new commands based on shell history and context. A standout feature is Goal Mode, which allows GPT to act as an agent executing commands autonomously to reach user-defined goals, such as debugging or file management tasks. The tool transparently displays prompts sent to the AI, supports customization of prompts, and allows switching models or pointing to local servers. It also offers a Neovim plugin for seamless prompting within code editing. Installation is straightforward on MacOS and Linux, with configuration options for API keys, models, and other parameters. Butterfish aims to streamline workflows, improve productivity, and make shell tasks more intelligent and conversational, all while maintaining transparency and user control.
