Goose

Goose is an open-source AI developer agent created by Block (the company formerly known as Square) that operates from your terminal to automate a wide range of engineering tasks, including writing code, managing files, running shell commands, and interacting with external services through an extensible toolkit system. It is designed to be a general-purpose development assistant that fits naturally into command-line workflows. The standout feature of Goose is its extensible toolkit architecture. Rather than being limited to a fixed set of capabilities, Goose supports toolkits that can be added to extend its abilities. The default toolkits handle common tasks like file operations, shell commands, and code editing, but you can add toolkits for interacting with specific services, databases, APIs, or internal tools. This extensibility makes Goose adaptable to a wide variety of development workflows and organizational contexts. Goose also maintains session memory across multi-turn interactions, so you can have an extended working session where the agent builds on previous context and instructions. Goose supports multiple LLM providers, allowing developers to connect it to Anthropic's Claude, OpenAI's models, or other compatible providers. It operates directly in your terminal, which means it integrates naturally with existing development workflows -- you can use it alongside your regular terminal commands, pipe output to and from it, and incorporate it into scripts. The agent takes a conversational approach where you describe what you want to accomplish and it plans and executes the steps, asking for clarification when needed. Goose is best suited for developers who are comfortable working in the terminal and want an AI agent that can be customized to their specific workflow through the toolkit system. It is particularly appealing to teams at organizations that use Block's other open-source tools or that need an agent they can extend with custom integrations. Being backed by Block, a major technology company, provides some confidence in the project's longevity and maintenance. Goose is free and open-source, with costs limited to API usage from your chosen LLM provider. Developers who prefer graphical interfaces or IDE integration may find terminal-only operation limiting, and the documentation is still evolving as the project matures.
