Create sandboxes (Windows/Linux/Android)
List, get details, and delete sandboxes
Monitor sandbox state and lifecycle
Perform GUI Automation
Desktop (Windows/Linux): Mouse clicks, keyboard input, scrolling, dragging
Mobile (Android): Touch, swipe, long press, app management
Take screenshots for visual feedback
Execute Code and Commands
Run Python, Node.js, Go, Rust, Java code
Execute shell commands and scripts
Handle stdin/stdout/stderr with base64 encoding
Manage Files

Forward sandbox ports to public URLs
Enable external access to sandbox services
Project Management
Create and organize projects
Manage sandboxes within projects
Track organization usage

Prerequisites

The Lybic Python SDK must be installed:

bash

pip install lybic

Users need Lybic credentials set via environment variables:

LYBIC_ORG_ID - Organization ID
LYBIC_API_KEY - API key

Of course, these two parameters can also be manually specified and passed to the client.

python

import asyncio
from lybic import LybicClient, LybicAuth

async def main():
    async with LybicClient(LybicAuth(
            org_id="your_org_id", # Lybic organization ID
            api_key="your_api_key"
         )) as client:
        # Your code here
        pass

Code Guidelines

1. Always use async/await pattern

python

import asyncio
from lybic import LybicClient

async def main():
    async with LybicClient() as client:
        # Your code here
        pass

if __name__ == '__main__':
    asyncio.run(main())

2. Use proper error handling

python

try:
    result = await client.sandbox.create(name="test", shape="beijing-2c-4g-cpu-linux")
    print(f"Created: {result.id}")
except Exception as e:
    print(f"Error: {e}")

3. Handle base64 encoding for process I/O

python

import base64

# For stdin
code = "print('hello')"
stdin_b64 = base64.b64encode(code.encode()).decode()

# For stdout/stderr
result = await client.sandbox.execute_process(...)
output = base64.b64decode(result.stdoutBase64 or '').decode()

4. Use fractional coordinates for GUI actions

python

# Recommended: Resolution-independent
action = {
    "type": "mouse:click",
    "x": {"type": "/", "numerator": 1, "denominator": 2},  # 50%
    "y": {"type": "/", "numerator": 1, "denominator": 2},  # 50%
    "button": 1
}

# Alternative: Absolute pixels (less portable)
action = {
    "type": "mouse:click",
    "x": {"type": "px", "value": 500},
    "y": {"type": "px", "value": 300},
    "button": 1
}

Common Patterns

Pattern 1: Create sandbox and run code

python

import asyncio
import base64
from lybic import LybicClient

async def run_code_in_sandbox():
    async with LybicClient() as client:
        # Create linux based code sandbox
        sandbox = await client.sandbox.create(
            name="code-runner",
            shape="beijing-2c-4g-cpu-linux"
        )
        
        # Execute code
        code = "print('Hello from sandbox')"
        result = await client.sandbox.execute_process(
            sandbox.id,
            executable="python3",
            stdinBase64=base64.b64encode(code.encode()).decode()
        )
        
        print(base64.b64decode(result.stdoutBase64).decode())
        
        # Cleanup
        await client.sandbox.delete(sandbox.id)

asyncio.run(run_code_in_sandbox())

Pattern 2: GUI automation with screenshot

python

import asyncio
from lybic import LybicClient

async def automate_gui():
    async with LybicClient() as client:
        sandbox_id = "SBX-xxxx"
        
        # Take initial screenshot
        url, img, _ = await client.sandbox.get_screenshot(sandbox_id)
        img.show()
        
        # Click at center
        await client.sandbox.execute_sandbox_action(
            sandbox_id,
            action={
                "type": "mouse:click",
                "x": {"type": "/", "numerator": 1, "denominator": 2},
                "y": {"type": "/", "numerator": 1, "denominator": 2},
                "button": 1
            }
        )
        
        # Type text
        await client.sandbox.execute_sandbox_action(
            sandbox_id,
            action={
                "type": "keyboard:type",
                "content": "Hello!"
            }
        )
        
        # Press Enter
        await client.sandbox.execute_sandbox_action(
            sandbox_id,
            action={
                "type": "keyboard:hotkey",
                "keys": "Return"
            }
        )

asyncio.run(automate_gui())

Pattern 3: Download file and process

python

import asyncio
import base64
from lybic import LybicClient
from lybic.dto import FileCopyItem, HttpGetLocation, SandboxFileLocation

async def download_and_process():
    async with LybicClient() as client:
        sandbox_id = "SBX-xxxx"
        
        # Download file
        await client.sandbox.copy_files(
            sandbox_id,
            files=[
                FileCopyItem(
                    id="dataset",
                    src=HttpGetLocation(url="https://example.com/data.csv"),
                    dest=SandboxFileLocation(path="/tmp/data.csv")
                )
            ]
        )
        
        # Process with Python
        code = """
import pandas as pd
df = pd.read_csv('/tmp/data.csv')
print(df.describe())
"""
        result = await client.sandbox.execute_process(
            sandbox_id,
            executable="python3",
            stdinBase64=base64.b64encode(code.encode()).decode()
        )
        
        print(base64.b64decode(result.stdoutBase64).decode())

asyncio.run(download_and_process())

Action Reference

Mouse Actions (Computer Use)

python

# Click
{"type": "mouse:click", "x": {...}, "y": {...}, "button": 1}  # 1=left, 2=right

# Double-click
{"type": "mouse:doubleClick", "x": {...}, "y": {...}, "button": 1}

# Move
{"type": "mouse:move", "x": {...}, "y": {...}}

# Drag
{"type": "mouse:drag", "startX": {...}, "startY": {...}, "endX": {...}, "endY": {...}}

# Scroll
{"type": "mouse:scroll", "x": {...}, "y": {...}, "stepVertical": -5, "stepHorizontal": 0}

Keyboard Actions (Computer Use)

python

# Type text
{"type": "keyboard:type", "content": "Hello, World!"}

# Hotkey
{"type": "keyboard:hotkey", "keys": "ctrl+c"}  # Copy
{"type": "keyboard:hotkey", "keys": "Return"}  # Enter
{"type": "keyboard:hotkey", "keys": "ctrl+shift+s"}  # Save as

Touch Actions (Mobile Use)

python

# Tap
{"type": "touch:tap", "x": {...}, "y": {...}}

# Long press
{"type": "touch:longPress", "x": {...}, "y": {...}, "duration": 2000}

# Swipe
{"type": "touch:swipe", "x": {...}, "y": {...}, "direction": "up", "distance": {...}}

# Android buttons
{"type": "android:back"}
{"type": "android:home"}

App Management (Mobile Use)

python

# Start app
{"type": "os:startApp", "packageName": "com.android.chrome"}
{"type": "os:startAppByName", "name": "Chrome"}

# Close app
{"type": "os:closeApp", "packageName": "com.android.chrome"}
{"type": "os:closeAppByName", "name": "Chrome"}

# List apps
{"type": "os:listApps"}

Common Actions

python

# Screenshot
{"type": "screenshot"}

# Wait
{"type": "wait", "duration": 3000}  # milliseconds

# Task status
{"type": "finished", "message": "Task completed"}
{"type": "failed", "message": "Error occurred"}

Best Practices

Use fractional coordinates: More portable across different screen resolutions
Take screenshots: Help verify GUI state before and after actions
Handle errors: Always wrap API calls in try-except blocks
Clean up resources: Delete sandboxes when done to avoid charges
Base64 encode I/O: Remember stdin/stdout use base64 encoding
Check exit codes: Use exitCode to verify process success (0 = success)

Sandbox Shapes

Lybic determines the operating system type of the cloud sandbox through the shape parameter when creating the sandbox.

Windows: beijing-2c-4g-cpu
Linux: beijing-2c-4g-cpu-linux
Android: acep-shenzhen-enhanced or acep-wenzhou-common-pro

Troubleshooting

Sandbox not ready: Wait longer after creation, check status with get()
Action fails: Verify coordinates are within screen bounds
Process timeout: Long-running processes need special handling (see docs)
File not found: Ensure paths exist in sandbox before accessing
Import errors: Verify package is pre-installed or install with pip3 install

When to Use This Skill

Use this skill when users need to:

Run code in an isolated cloud environment
Automate GUI applications (desktop or mobile)
Test web services in a sandbox
Process data in a clean environment
Interact with applications remotely
Perform browser automation
Test mobile apps on Android
