Goose — Extensible AI Agent by Block

Overview

Goose is an open-source AI agent from Block (formerly Square) that operates as a full system agent — not just a code assistant. It can install packages, execute shell commands, edit files, run tests, browse the web, and interact with external services through extensions.
