The Complete Guide to Goose: Block’s Open-Source AI Development Agent for 2026
Release Date: March 2026 · Version: v1.0+ · License: Apache 2.0 · Execution Mode: Local
In early 2026, Block (formerly Square) officially open-sourced Goose—an AI agent capable of autonomously executing complex software development tasks. Unlike traditional code-completion tools, Goose does more than generate code: it independently runs commands, debugs errors, orchestrates multi-step workflows, and can even build complete projects from scratch.
Goose’s core philosophy is the “on-machine AI agent”: all operations execute locally, ensuring code privacy and security. It supports any LLM provider, enables configurable multi-model strategies to optimize performance and cost, and seamlessly integrates external tools and services via the MCP (Model Context Protocol).

default_model: claude-3-5-sonnet
workspace: ~/projects
Core Feature Details
1. Autonomous Task Execution
Goose’s most powerful capability is autonomously completing multi-step tasks. For example, creating a complete API service:
# Tell Goose your requirements
goose run "Create a FastAPI project with user registration, login, and JWT authentication"
Goose will automatically:
1. Create the project structure and necessary files
2. Implement routes, data models, and authentication logic
3. Install required dependencies
4. Run tests to verify functionality
5. Generate API documentation
2. MCP Server Integration
Goose natively supports MCP (Model Context Protocol) and can connect to various external tools:
# Add MCP servers in the configuration file
mcp_servers:
- name: filesystem
command: npx
args: ["-y", "@modelcontextprotocol/server-filesystem", "~/projects"]
- name: github
command: npx
args: ["-y", "@modelcontextprotocol/server-github"]
env:
GITHUB_TOKEN: ${GITHUB_TOKEN}
- name: postgres
command: npx
args: ["-y", "@modelcontextprotocol/server-postgres"]
env:
DATABASE_URL: postgresql://localhost:5432/mydb
Commonly Used MCP Servers:
| Server | Functionality | Installation Command |
|---|---|---|
filesystem |
File system operations | @modelcontextprotocol/server-filesystem |
github |
GitHub API integration | @modelcontextprotocol/server-github |
postgres |
PostgreSQL database access | @modelcontextprotocol/server-postgres |
slack |
Slack messaging | @modelcontextprotocol/server-slack |
puppeteer |
Browser automation | @modelcontextprotocol/server-puppeteer |
3. Multi-Model Strategy
Goose supports assigning different models to different task types—optimizing both cost and performance:
routing:
# Use high-performance models for code generation
code_generation:
model: claude-3-5-sonnet
max_tokens: 4096
# Use local models for simple tasks
simple_tasks:
model: ollama/qwen3-coder:7b
max_tokens: 2048
# Use cost-efficient models for code review
code_review:
model: gpt-4o-mini
max_tokens: 1024
4. Extension System
Goose supports custom extensions to add domain-specific capabilities:
# extensions/my_extension.py
from goose.extensions import Extension
class MyExtension(Extension):
"""Example of a custom extension"""
def __init__(self):
self.name = "my-extension"
self.version = "1.0.0"
async def deploy_to_server(self, project_path: str):
"""Custom deployment logic"""
# Implement deployment logic here
pass
async def run_tests(self, project_path: str):
"""Custom test execution logic"""
# Implement test logic here
pass
Real-World Use Cases
Case 1: Automated Data Migration
# Create a migration task
goose run "
Migrate user data from a MySQL database to PostgreSQL:
1. Read the `users` table from MySQL
2. Transform the data structure to conform to PostgreSQL schema requirements
3. Write the transformed data into the PostgreSQL database
4. Verify data integrity
5. Generate a migration report
"
Case 2: Batch Code Refactoring
# Refactor error handling across the entire project
goose run "
Refactor error handling in all Python files within the project:
- Standardize `try-except` blocks to use custom exception classes
- Add appropriate logging statements
- Introduce retry logic for all API calls
- Update test cases to cover the new exceptions
"
Case 3: API Documentation Generation
# Generate comprehensive API documentation from source code
goose run "
Analyze the project’s API routes and generate:
1. An OpenAPI 3.0 specification file
2. Usage documentation in Markdown format
3. A Postman collection file
4. An interactive API testing page
"
Best Practices
1. Security Configuration
# Restrict Goose’s permission scope
security:
# Whitelist of allowed commands
allowed_commands:
- git
- npm
- pip
- python
- docker
# Directories prohibited from access
blocked_paths:
- ~/.ssh
- /etc/passwd
- /etc/shadow
# Dangerous operations requiring confirmation
require_confirmation:
- rm -rf
- DROP TABLE
- DELETE FROM
2. Performance Optimization
# Optimization settings
performance:
# Maximum number of concurrent tasks
max_concurrent_tasks: 4
# Timeout for individual tasks (in seconds)
task_timeout: 300
# Enable caching
cache:
enabled: true
ttl_hours: 24
# Enable streaming output (to reduce memory usage)
streaming: true
3. Logging and Debugging
# Enable verbose logging
goose run "Task description" --verbose
# View execution history
goose history --limit 10
# Export session report
goose report --format markdown --output session-report.md
Frequently Asked Questions (FAQ)

- qwen3-coder:32b
Q3: How are sensitive data protected?
A: Goose supports environment variables and encrypted configuration files:
# Using environment variables
export OPENAI_API_KEY="sk-..."
goose run "task"
# Or using an encrypted configuration file
goose config encrypt
Q4: Is Chinese supported?
