an open source, extensible AI agent that goes beyond code suggestions - install, execute, edit, and test with any LLM
Goose is an open-source AI agent that runs on a computer as a desktop app, command-line tool, or API and can perform tasks beyond code completion. Developers and other users employ it for coding, research, writing, automation, and data analysis with different language-model providers and extensions. The catalogue add-ons define parts of its agent workflow and behavior.
