Goose
What is Goose?
Goose is an open-source, extensible AI agent framework designed to run natively on user machines (desktop app, CLI, and API). Built in Rust for performance and portability, it serves as a general-purpose agentic platform for code development, research, writing, automation, and data analysis. Unlike single-purpose AI tools, Goose implements a sophisticated architecture centered around protocol-based interoperability, particularly the Model Context Protocol (MCP) and Agent Client Protocol (ACP).
Core Technical Architecture
1. Multi-Interface Architecture
- Desktop Application: Native cross-platform application for macOS, Linux, and Windows with rich UI capabilities including MCP Apps (interactive UIs rendered directly in the desktop interface)
- Command-Line Interface (CLI): Full-featured terminal interface supporting scripting, automation, and integration into developer workflows
- API Layer: Embeddable API enabling integration into custom applications, CI/CD pipelines, and enterprise systems
2. Protocol-Based Extensibility Framework
- Model Context Protocol (MCP) Integration: Goose implements one of the deepest MCP integrations in the ecosystem, supporting over 70+ extensions that connect to databases, APIs, browsers, GitHub, Google Drive, and other external services
- Agent Client Protocol (ACP) Support: Functions as both an ACP server (enabling integration with editors like Zed, JetBrains, and VS Code) and supports ACP providers (Claude Code, Codex, Amp, Pi) to leverage existing AI subscriptions
- Extension Architecture: Built-in extension manager with security scanning for malware detection before activation
3. Context Management System
- Session Management: Persistent context-aware sessions that maintain conversation history and state across interactions
- Memory Extension: Persistent knowledge storage system with local (project-specific) and global (user-wide) scope, supporting category-based organization and tag-based retrieval
- Context Engineering: Comprehensive system for building background knowledge through .goosehints files, skills, persistent instructions, hooks, and prompt templates
4. Workflow Automation Capabilities
- Recipes: Reusable YAML-based workflow configurations that package extensions, prompts, and settings together for consistent, shareable automation
- Subagents: Isolated, parallelizable agent instances that can handle focused tasks while keeping the main conversation clean, supporting both sequential and concurrent execution patterns
- Slash Commands: Custom shortcuts for quickly executing reusable instructions in any chat session
5. Security Architecture
- Adversary Mode: Independent agent reviewer that monitors tool calls for potentially harmful actions
- Prompt Injection Detection: Built-in protection against malicious command injection
- Permission Controls: Configurable permission modes (autonomous, manual approval, smart approval) with granular tool-level access control
- Sandbox Mode: Isolated execution environment for enhanced security

FAQs
What is Goose?
goose is an on-machine AI agent, capable of automating complex development tasks from start to finish. More than just code suggestions, goose can build entire projects from scratch, write and execute code, debug failures, orchestrate workflows, and interact with external APIs autonomously.
