Goose

Goose is an open-source AI agent that automates software development tasks by directly interacting with your local shell, filesystem, and editor.

Goose turns LLMs into active contributors. Built by Block, this Rust-based CLI executes complex engineering workflows (like migrating a legacy Python 2 codebase to Python 3.12 or refactoring React components) by managing its own environment. It uses the Model Context Protocol (MCP) to extend its capabilities, allowing it to browse documentation, run unit tests, and commit code changes autonomously. You provide the objective: Goose handles the execution.
