title: Client Integrations

## Claude Desktop Integration
To use with Claude Desktop, add an entry to your Claude Desktop configuration (`claude_desktop_config.json`, typically found in `~/.config/claude-desktop/`):
For more information on MCP with Claude Desktop, see the [official MCP User Guide](https://modelcontextprotocol.io/quickstart/user).
## Cursor Integration
To use with Cursor, add an MCP configuration file in one of these locations:
- **Project-specific**: Create `.cursor/mcp.json` in your project directory
- **Global**: Create `~/.cursor/mcp.json` in your home directory
After configuration, you can simply tell Cursor's Agent to perform computer tasks by explicitly mentioning the CUA agent, such as "Use the computer control tools to open Safari."
For more information on MCP with Cursor, see the [official Cursor MCP documentation](https://docs.cursor.com/context/model-context-protocol).

title: Benchmarks
description: Computer Agent SDK benchmarks for agentic GUI tasks
---
The benchmark system evaluates models on GUI grounding tasks, specifically agent loop success rate and click prediction accuracy. It supports both:
- **Computer Agent SDK providers** (using model strings like `"huggingface-local/HelloKKMe/GTA1-7B"`)
- **Reference agent implementations** (custom model classes implementing the `ModelProtocol`)
## Available Benchmarks
- **[ScreenSpot-v2](./benchmarks/screenspot-v2)** - Standard resolution GUI grounding
- **[ScreenSpot-Pro](./benchmarks/screenspot-pro)** - High-resolution GUI grounding
- **[Interactive Testing](./benchmarks/interactive)** - Real-time testing and visualization
## Quick Start
```bash
# Clone the benchmark repository
git clone https://github.com/trycua/cua
cd libs/python/agent/benchmarks
# Install dependencies
pip install "cua-agent[all]"
# Run a benchmark
python ss-v2.py

You can also use Docker Compose to run Lumier with a simple configuration file. Create a `docker-compose.yml` file with the following content:
```yaml
version: '3'
services:
lumier:
image: trycua/lumier:latest
container_name: lumier-vm
restart: unless-stopped
ports:
- "8006:8006" # Port for VNC access
volumes:
- ./storage:/storage # VM persistent storage
- ./shared:/shared # Shared folder accessible in the VM
environment:
- VM_NAME=lumier-vm

- RAM_SIZE=8192
- HOST_STORAGE_PATH=${PWD}/storage
- HOST_SHARED_PATH=${PWD}/shared
stop_signal: SIGINT
stop_grace_period: 2m
```
Then run Lumier using:
```bash
# First create the required directories
mkdir -p storage shared
# Start the container
docker-compose up -d
# View the logs
docker-compose logs -f
# Stop the container when done
docker-compose down

title: Running Models Locally
---
You can run open-source LLMs and vision models on your own machine using cua, without relying on cloud APIs. This is ideal for development, privacy, or running on air-gapped systems.
## Hugging Face (transformers)
Use the `huggingface-local/` prefix to run any Hugging Face model locally via the `transformers` library. This supports most text and vision models from the Hugging Face Hub.
**Example:**
```python
model = "huggingface-local/ByteDance-Seed/UI-TARS-1.5-7B"
```
## MLX (Apple Silicon)
Use the `mlx/` prefix to run models using the `mlx-vlm` library, optimized for Apple Silicon (M1/M2/M3). This allows fast, local inference for many open-source models.
**Example:**
```python
model = "mlx/mlx-community/UI-TARS-1.5-7B-6bit"
```
## Ollama
Use the `ollama_chat/` prefix to run models using the `ollama` library. This allows fast, local inference for many open-source models.
**Example:**
```python
model = "omniparser+ollama_chat/llama3.2:latest"
```
```

title: Custom Tools
slug: custom-tools
---
The Agent SDK supports defining custom Python tools that run securely in sandboxed environments on remote Cua Computers. This enables safe execution of user-defined functions, isolation of dependencies, and robust automation workflows.
## Custom Tools
Define a custom tool for an agent:
```python
def calculate(a: int, b: int) -> int:
"""Calculate the sum of two integers"""
return a + b
# Use with agent
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer, calculate]
)
```
## Sandboxed Tools
Define a sandboxed tool:
```python
from computer.helpers import sandboxed
@sandboxed()
def read_file(location: str) -> str:
"""Read contents of a file"""
with open(location, 'r') as f:
return f.read()
```
You can then register this as a tool for your agent:
```python
from agent import ComputerAgent
from computer import Computer
computer = Computer(...)
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer, read_file],
)
```

title: Building Lumier
---
If you want to customize the Lumier container or build it from source, you can follow these steps:
```bash
# 1. Navigate to the Lumier directory
cd libs/lumier
# 2. Build the Docker image locally
docker build -t lumier-custom:latest .
# 3. Run your custom build
docker run -it --rm \
--name lumier-vm \
-p 8006:8006 \
-e VM_NAME=lumier-vm \
-e VERSION=ghcr.io/trycua/macos-sequoia-cua:latest \
-e CPU_CORES=4 \
-e RAM_SIZE=8192 \
lumier-custom:latest
```
### Customization Options
The Dockerfile provides several customization points:
1. **Base image**: The container uses Debian Bullseye Slim as the base. You can modify this if needed.
2. **Installed packages**: You can add or remove packages in the apt-get install list.
3. **Hooks**: Check the `/run/hooks/` directory for scripts that run at specific points during VM lifecycle.
4. **Configuration**: Review `/run/config/constants.sh` for default settings.
After making your modifications, you can build and push your custom image to your own Docker Hub repository:
```bash
# Build with a custom tag
docker build -t yourusername/lumier:custom .
# Push to Docker Hub (after docker login)
docker push yourusername/lumier:custom
```
```

title: Lumier
description: Reference for the current version of the Lumier library.
github:
- https://github.com/trycua/cua/tree/main/libs/lumier
---
**Lumier** is an interface for running macOS virtual machines with minimal setup. It uses Docker as a packaging system to deliver a pre-configured environment that connects to the `lume` virtualization service running on your host machine. With Lumier, you get:
- A ready-to-use macOS or Linux virtual machine in minutes
- Browser-based VNC access to your VM
- Easy file sharing between your host and VM
- Simple configuration through environment variables
## How It Works
<Callout title="Note">
We're using Docker primarily as a convenient delivery mechanism, not as an isolation layer. Unlike traditional Docker containers, Lumier leverages the Apple Virtualization Framework (Apple Vz) through the `lume` CLI to create true virtual machines.
</Callout>
Here's what's happening behind the scenes:
1. The Docker container provides a consistent environment to run the Lumier interface
2. Lumier connects to the Lume service running on your host Mac
3. Lume uses Apple's Virtualization Framework to create a true macOS virtual machine
4. The VM runs with hardware acceleration using your Mac's native virtualization capabilities

--------------------------------------------------------------------------------
```markdown
---
title: Installation
---
Install the package from PyPI:
```bash
pip install cua-mcp-server
```
This will install:
- The MCP server
- CUA agent and computer dependencies
- An executable `cua-mcp-server` script in your PATH
## Easy Setup Script
If you want to simplify installation, you can use this one-liner to download and run the installation script:
```bash
curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/python/mcp-server/scripts/install_mcp_server.sh | bash
```
This script will:
- Create the ~/.cua directory if it doesn't exist
- Generate a startup script at ~/.cua/start_mcp_server.sh
- Make the script executable
- The startup script automatically manages Python virtual environments and installs/updates the cua-mcp-server package
You can then use the script in your MCP configuration like this:
```json
{
"mcpServers": {
"cua-agent": {
"command": "/bin/bash",
"args": ["~/.cua/start_mcp_server.sh"],
"env": {
"CUA_MODEL_NAME": "anthropic/claude-3-5-sonnet-20241022"
}
}
}
}
```
### Troubleshooting
If you get a `/bin/bash: ~/cua/libs/python/mcp-server/scripts/start_mcp_server.sh: No such file or directory` error, try changing the path to the script to be absolute instead of relative.
To see the logs:
```
tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
```
```

# Trajectory Saving Callback
The TrajectorySaverCallback records complete agent conversations including messages, actions, and screenshots for debugging and analysis.
## Callbacks Example
```python
from agent.callbacks import TrajectorySaverCallback
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
callbacks=[
TrajectorySaverCallback(
trajectory_dir="my_trajectories",
save_screenshots=True
)
]
)
```
## Shorthand
```python
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
trajectory_dir="trajectories", # Auto-save trajectories
tools=[computer]
)
```
## View Trajectories Online
View trajectories in the browser at:
**[trycua.com/trajectory-viewer](http://trycua.com/trajectory-viewer)**
The viewer provides:
- Interactive conversation replay
- Screenshot galleries
- No data collection
## Trajectory Structure
Trajectories are saved with:
- Complete conversation history
- Usage statistics and costs
- Timestamps and metadata
- Screenshots and computer actions
Each trajectory contains:
- **metadata.json**: Run info, timestamps, usage stats (`total_tokens`, `response_cost`)
- **turn_000/**: Turn-by-turn conversation history (api calls, responses, computer calls, screenshots)

# Development Guide
This guide will help you set up your development environment and understand the process for contributing code to lume.
## Environment Setup
Lume development requires:
- Swift 6 or higher
- Xcode 15 or higher
- macOS Sequoia 15.2 or higher
- (Optional) VS Code with Swift extension
If you're working on Lume in the context of the Cua monorepo, we recommend using the dedicated VS Code workspace configuration:
```bash
# Open VS Code workspace from the root of the monorepo
code .vscode/lume.code-workspace
```
This workspace is preconfigured with Swift language support, build tasks, and debug configurations.
## Setting Up the Repository Locally
1. **Fork the Repository**: Create your own fork of lume
2. **Clone the Repository**:
```bash
git clone https://github.com/trycua/lume.git
cd lume
```
3. **Install Dependencies**:
```bash
swift package resolve
```
4. **Build the Project**:
```bash
swift build
```
## Development Workflow
1. Create a new branch for your changes
2. Make your changes
3. Run the tests: `swift test`
4. Build and test your changes locally
5. Commit your changes with clear commit messages
## Submitting Pull Requests
1. Push your changes to your fork
2. Open a Pull Request with:
- A clear title and description
- Reference to any related issues
- Screenshots or logs if relevant
3. Respond to any feedback from maintainers
```

# REST API Reference
The Computer Server exposes a single REST endpoint for command execution:
- `http://localhost:8000/cmd`
- `https://your-container.containers.cloud.trycua.com:8443/cmd` (cloud)
## POST /cmd
- Accepts commands as JSON in the request body
- Returns results as a streaming response (text/event-stream)
### Request Format
```json
{
"command": "<command_name>",
"params": { ... }
}
```
### Required Headers (for cloud containers)
- `X-Container-Name`: Name of the container (cloud only)
- `X-API-Key`: API key for authentication (cloud only)
### Example Request (Python)
```python
import requests
url = "http://localhost:8000/cmd"
body = {"command": "screenshot", "params": {}}
resp = requests.post(url, json=body)
print(resp.text)
```
### Example Request (Cloud)
```python
import requests
url = "https://your-container.containers.cloud.trycua.com:8443/cmd"
headers = {
"X-Container-Name": "your-container",
"X-API-Key": "your-api-key"
}
body = {"command": "screenshot", "params": {}}
resp = requests.post(url, json=body, headers=headers)
print(resp.text)
```
### Response Format
Streaming text/event-stream with JSON objects, e.g.:
```
data: {"success": true, "content": "..."}
data: {"success": false, "error": "..."}
```
### Supported Commands
See [Commands Reference](./Commands) for the full list of commands and parameters.

title: Agent Lifecycle
description: Agent callback lifecycle and hooks
---
# Callbacks
Callbacks provide hooks into the agent lifecycle for extensibility. They're called in a specific order during agent execution.
## Callback Lifecycle
### 1. `on_run_start(kwargs, old_items)`
Called once when agent run begins. Initialize tracking, logging, or state.
### 2. `on_run_continue(kwargs, old_items, new_items)` → bool
Called before each iteration. Return `False` to stop execution (e.g., budget limits).
### 3. `on_llm_start(messages)` → messages
Preprocess messages before LLM call. Use for PII anonymization, image retention.
### 4. `on_api_start(kwargs)`
Called before each LLM API call.
### 5. `on_api_end(kwargs, result)`
Called after each LLM API call completes.
### 6. `on_usage(usage)`
Called when usage information is received from LLM.
### 7. `on_llm_end(messages)` → messages
Postprocess messages after LLM call. Use for PII deanonymization.
### 8. `on_responses(kwargs, responses)`
Called when responses are received from agent loop.
### 9. Response-specific hooks:
- `on_text(item)` - Text messages
- `on_computer_call_start(item)` - Before computer actions
- `on_computer_call_end(item, result)` - After computer actions
- `on_function_call_start(item)` - Before function calls
- `on_function_call_end(item, result)` - After function calls
- `on_screenshot(screenshot, name)` - When screenshots are taken
### 10. `on_run_end(kwargs, old_items, new_items)`

title: Prebuilt Images
---
Pre-built images are available in the registry [ghcr.io/trycua](https://github.com/orgs/trycua/packages). These images come with an SSH server pre-configured and auto-login enabled.
<Callout>
The default password on pre-built images is `lume`. For the security of your VM, change this password after your first login.
</Callout>
## Available Images
The following pre-built images are available to download via `lume pull`:
| Image | Tag | Description | Logical Size |
|-------|------------|-------------|------|
| `macos-sequoia-vanilla` | `latest`, `15.2` | macOS Sequoia 15.2 image | 20GB |
| `macos-sequoia-xcode` | `latest`, `15.2` | macOS Sequoia 15.2 image with Xcode command line tools | 22GB |
| `macos-sequoia-cua` | `latest`, `15.3` | macOS Sequoia 15.3 image compatible with the Computer interface | 24GB |
| `ubuntu-noble-vanilla` | `latest`, `24.04.1` | [Ubuntu Server for ARM 24.04.1 LTS](https://ubuntu.com/download/server/arm) with Ubuntu Desktop | 20GB |
## Disk Space
For additional disk space, resize the VM disk after pulling the image using the `lume set <name> --disk-size <size>` command. Note that the actual disk space used by sparse images will be much lower than the logical size listed.
<Callout>
**Important Note (v0.2.0+):** Images are being re-uploaded with sparse file system optimizations enabled, resulting in significantly lower actual disk usage. Older images (without the `-sparse` suffix) are now **deprecated**. The last version of `lume` fully supporting the non-sparse images was `v0.1.x`. Starting from `v0.2.0`, lume will automatically pull images optimized with sparse file system support.

title: Installation
description: Installation instructions for the current version of the Lume CLI.
---
## Quickstart
Install and run a prebuilt macOS VM in two commands:
```bash
# Install Lume
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/lume/scripts/install.sh)"
# Pull & start a macOS image
lume run macos-sequoia-vanilla:latest
```
<Callout title="Security Note">
All prebuilt images use the default password `lume`. Change this immediately after your first login using the `passwd` command.
</Callout>
**System Requirements**:
- Apple Silicon Mac (M1, M2, M3, etc.)
- macOS 13.0 or later
- At least 8GB of RAM (16GB recommended)
- At least 50GB of free disk space
## Install with Script
Install with a single command:
```bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/lume/scripts/install.sh)"
```
### Manual Start (No Background Service)
By default, Lume is installed as a background service that starts automatically on login. If you prefer to start the Lume API service manually when needed, you can use the `--no-background-service` option:
```bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/lume/scripts/install.sh) --no-background-service"
```
<Callout title="Note">
With this option, you'll need to manually start the Lume API service by running `lume serve` in your terminal whenever you need to use tools or libraries that rely on the Lume API (such as the Computer-Use Agent).
</Callout>
## Manual Download and Installation
You can also download the `lume.pkg.tar.gz` archive from the [latest release](https://github.com/trycua/cua/releases?q=lume&expanded=true), extract it, and install the package manually.

title: Usage Tracking
sidebar_position: 9
description: How to track token usage and cost in ComputerAgent and agent loops.
---
Tracking usage is important for monitoring costs and optimizing your agent workflows. The ComputerAgent API provides easy access to token and cost usage for every run.
## Accessing Usage Data
Whenever you run an agent loop, each result contains a `usage` dictionary with token and cost information:
```python
async for result in agent.run(...):
print(result["usage"])
# Example output:
# {
# "prompt_tokens": 150,
# "completion_tokens": 75,
# "total_tokens": 225,
# "response_cost": 0.01,
# }
```
- `prompt_tokens`: Number of tokens in the prompt
- `completion_tokens`: Number of tokens in the agent's response
- `total_tokens`: Total tokens used
- `response_cost`: Estimated cost (USD) for this turn
## Tracking Total Usage
You can accumulate usage across multiple turns:
```python
total_usage = {"prompt_tokens": 0, "completion_tokens": 0, "total_tokens": 0, "response_cost": 0.0}
async for result in agent.run(...):
for k in total_usage:
total_usage[k] += result["usage"].get(k, 0)
print("Total usage:", total_usage)
```
## Using Callbacks for Usage Tracking
You can also use a callback to automatically track usage. Implement the `on_usage` method in your callback class:
```python
from agent.callbacks import AsyncCallbackHandler
class UsageTrackerCallback(AsyncCallbackHandler):
async def on_usage(self, usage):
print("Usage update:", usage)
agent = ComputerAgent(
...,
callbacks=[UsageTrackerCallback()]
)
```

title: Human-In-The-Loop
description: Use humans as agents for evaluation, demonstrations, and interactive control
---
The Agent SDK provides a human tool, with native support for using a human-in-the-loop as a way to evaluate your environment, tools, or to create demonstrations. You can use it by doing `grounding_model+human/human` or `human/human` directly.
## Getting Started
To start the human agent tool, simply run:
```bash
python -m agent.human_tool
```
The UI will show you pending completions. Select a completion to take control of the agent.
## Usage Examples
### Direct Human Agent
```python
from agent import ComputerAgent
from agent.computer import computer
agent = ComputerAgent(
"human/human",
tools=[computer]
)
async for _ in agent.run("Take a screenshot, analyze the UI, and click on the most prominent button"):
pass
```
### Composed with Grounding Model
```python
agent = ComputerAgent(
"huggingface-local/HelloKKMe/GTA1-7B+human/human",
tools=[computer]
)
async for _ in agent.run("Navigate to the settings page and enable dark mode"):
pass
```
## Features
The human-in-the-loop interface provides:
- **Interactive UI**: Web-based interface for reviewing and responding to agent requests
- **Image Display**: Screenshots with click handlers for direct interaction
- **Action Accordions**: Support for various computer actions (click, type, keypress, etc.)
- **Tool Calls**: Full OpenAI-compatible tool call support
- **Real-time Updates**: Smart polling for responsive UI updates
## Use Cases
- **Evaluation**: Have humans evaluate agent performance and provide ground truth responses
- **Demonstrations**: Create training data by having humans demonstrate tasks
- **Interactive Control**: Take manual control when automated agents need human guidance
- **Testing**: Validate agent, tool, and environment behavior manually

title: Prompt Caching
sidebar_position: 8
description: How to use prompt caching in ComputerAgent and agent loops.
---
Prompt caching is a cost-saving feature offered by some LLM API providers that helps avoid reprocessing the same prompt, improving efficiency and reducing costs for repeated or long-running tasks.
## Usage
The `use_prompt_caching` argument is available for `ComputerAgent` and agent loops:
```python
agent = ComputerAgent(
...,
use_prompt_caching=True,
)
```
- **Type:** `bool`
- **Default:** `False`
- **Purpose:** Use prompt caching to avoid reprocessing the same prompt.
## Anthropic CUAs
When using Anthropic-based CUAs (Claude models), setting `use_prompt_caching=True` will automatically add `{ "cache_control": "ephemeral" }` to your messages. This enables prompt caching for the session and can speed up repeated runs with the same prompt.
<Callout title="Note">
This argument is only required for Anthropic CUAs. For other providers, it is ignored.
</Callout>
## OpenAI Provider
With the OpenAI provider, prompt caching is handled automatically for prompts of 1000+ tokens. You do **not** need to set `use_prompt_caching`—caching will occur for long prompts without any extra configuration.
## Example
```python
from agent import ComputerAgent
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
use_prompt_caching=True,
)
```
## Implementation Details
- For Anthropic: Adds `{ "cache_control": "ephemeral" }` to messages when enabled.
- For OpenAI: Caching is automatic for long prompts; the argument is ignored.
## When to Use
- Enable for Anthropic CUAs if you want to avoid reprocessing the same prompt in repeated or iterative tasks.
- Not needed for OpenAI models unless you want explicit ephemeral cache control (not required for most users).

description: Reference for the current version of the Set-of-Mark library.
pypi: cua-som
github:
- https://github.com/trycua/cua/tree/main/libs/python/som
---
<Callout>A corresponding <a href="https://github.com/trycua/cua/blob/main/examples/som_examples.py" target="_blank">Python example</a> is available for this documentation.</Callout>
## Overview
The SOM library provides visual element detection and interaction capabilities. It is based on the [Set-of-Mark](https://arxiv.org/abs/2310.11441) research paper and the [OmniParser](https://github.com/microsoft/OmniParser) model.
## API Documentation
### OmniParser Class
```python
class OmniParser:
def __init__(self, device: str = "auto"):
"""Initialize the parser with automatic device detection"""
def parse(
self,
image: PIL.Image,
box_threshold: float = 0.3,
iou_threshold: float = 0.1,
use_ocr: bool = True,
ocr_engine: str = "easyocr"
) -> ParseResult:
"""Parse UI elements from an image"""
```
### ParseResult Object
```python
@dataclass
class ParseResult:
elements: List[UIElement] # Detected elements
visualized_image: PIL.Image # Annotated image
processing_time: float # Time in seconds
def to_dict(self) -> dict:
"""Convert to JSON-serializable dictionary"""
def filter_by_type(self, elem_type: str) -> List[UIElement]:
"""Filter elements by type ('icon' or 'text')"""
```
### UIElement
```python
class UIElement(BaseModel):
id: Optional[int] = Field(None) # Element ID (1-indexed)
type: Literal["icon", "text"] # Element type
bbox: BoundingBox # Bounding box coordinates { x1, y1, x2, y2 }
interactivity: bool = Field(default=False) # Whether the element is interactive
confidence: float = Field(default=1.0) # Detection confidence
```

# WebSocket API Reference
The Computer Server exposes a WebSocket endpoint for real-time command execution and streaming results.
- `ws://localhost:8000/ws`
- `wss://your-container.containers.cloud.trycua.com:8443/ws` (cloud)
### Authentication (Cloud Only)
For cloud containers, you must authenticate immediately after connecting:
```json
{
"command": "authenticate",
"params": {
"container_name": "your-container",
"api_key": "your-api-key"
}
}
```
If authentication fails, the connection is closed.
### Command Format
Send JSON messages:
```json
{
"command": "<command_name>",
"params": { ... }
}
```
### Example (Python)
```python
import websockets
import asyncio
import json
async def main():
uri = "ws://localhost:8000/ws"
async with websockets.connect(uri) as ws:
await ws.send(json.dumps({"command": "version", "params": {}}))
response = await ws.recv()
print(response)
asyncio.run(main())
```
### Example (Cloud)
```python
import websockets
import asyncio
import json
async def main():
uri = "wss://your-container.containers.cloud.trycua.com:8443/ws"
async with websockets.connect(uri) as ws:
await ws.send(json.dumps({
"command": "authenticate",
"params": {
"container_name": "your-container",
"api_key": "your-api-key"
}
}))
auth_response = await ws.recv()
print(auth_response)
await ws.send(json.dumps({"command": "version", "params": {}}))
response = await ws.recv()
print(response)
asyncio.run(main())
```
### Response Format
Each response is a JSON object:
```json
{
"success": true,
...
}
```
### Supported Commands
See [Commands Reference](./Commands) for the full list of commands and parameters.

### Detection Parameters
#### Box Threshold (0.3)
Controls the confidence threshold for accepting detections:
<img src="/docs/img/som_box_threshold.png" alt="Illustration of confidence thresholds in object detection, with a high-confidence detection accepted and a low-confidence detection rejected." width="500px" />
- Higher values (0.3) yield more precise but fewer detections
- Lower values (0.01) catch more potential icons but increase false positives
- Default is 0.3 for optimal precision/recall balance
#### IOU Threshold (0.1)
Controls how overlapping detections are merged:
<img src="/docs/img/som_iou_threshold.png" alt="Diagram showing Intersection over Union (IOU) with low overlap between two boxes kept separate and high overlap leading to merging." width="500px" />
- Lower values (0.1) more aggressively remove overlapping boxes
- Higher values (0.5) allow more overlapping detections
- Default is 0.1 to handle densely packed UI elements
### OCR Configuration
- **Engine**: EasyOCR
- Primary choice for all platforms
- Fast initialization and processing
- Built-in English language support
- GPU acceleration when available
- **Settings**:
- Timeout: 5 seconds
- Confidence threshold: 0.5
- Paragraph mode: Disabled
- Language: English only
## Performance
### Hardware Acceleration
#### MPS (Metal Performance Shaders)
- Multi-scale detection (640px, 1280px, 1920px)
- Test-time augmentation enabled
- Half-precision (FP16)
- Average detection time: ~0.4s
- Best for production use when available
#### CPU
- Single-scale detection (1280px)
- Full-precision (FP32)
- Average detection time: ~1.3s
- Reliable fallback option

# Cost Optimization Callbacks
Optimize agent costs with budget management and image retention callbacks.
## Budget Manager Callbacks Example
```python
from agent.callbacks import BudgetManagerCallback
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
callbacks=[
BudgetManagerCallback(
max_budget=5.0, # $5 limit
reset_after_each_run=False,
raise_error=True
)
]
)
```
## Budget Manager Shorthand
```python
# Simple budget limit
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
max_trajectory_budget=5.0 # $5 limit
)
```
**Or with options:**
```python
# Advanced budget configuration
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
max_trajectory_budget={
"max_budget": 10.0,
"raise_error": True, # Raise error when exceeded
"reset_after_each_run": False # Persistent across runs
}
)
```
## Image Retention Callbacks Example
```python
from agent.callbacks import ImageRetentionCallback
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
callbacks=[
ImageRetentionCallback(only_n_most_recent_images=3)
]
)
```
## Image Retention Shorthand
```python
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
only_n_most_recent_images=3 # Auto-adds ImageRetentionCallback
)
```
## Combined Cost Optimization
```python
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
max_trajectory_budget=5.0, # Budget limit
only_n_most_recent_images=3, # Image retention
trajectory_dir="trajectories" # Track spending
)
```
## Budget Manager Options
- `max_budget`: Dollar limit for trajectory
- `reset_after_each_run`: Reset budget per run (default: True)
- `raise_error`: Raise exception vs. graceful stop (default: False)
```

title: Callbacks
---
Callbacks in the Agent SDK provide hooks into the agent's lifecycle, allowing for custom functionality to be executed at various stages of an agent's run. They enable extensibility by allowing developers to integrate their own logic for tasks such as logging, cost management, and data anonymization.
## Usage
You can add preprocessing and postprocessing hooks using callbacks, or write your own by subclassing `AsyncCallbackHandler`.
### Built-in Callbacks
Built-in callbacks can be used as follows:
```python
from agent.callbacks import (
ImageRetentionCallback,
TrajectorySaverCallback,
BudgetManagerCallback,
LoggingCallback
)
agent = ComputerAgent(
model="anthropic/claude-3-5-sonnet-20241022",
tools=[computer],
callbacks=[
ImageRetentionCallback(only_n_most_recent_images=3),
TrajectorySaverCallback(trajectory_dir="trajectories"),
BudgetManagerCallback(max_budget=10.0, raise_error=True),
LoggingCallback(level=logging.INFO)
]
)
```
The following built-in callbacks are available:
- [BudgetManagerCallback](callbacks/cost-saving): Stops execution when budget exceeded
- [LoggingCallback](callbacks/trajectories): Logs agent activities
- **ImageRetentionCallback**: Limits recent images in context
- **TrajectorySaverCallback**: Saves conversation trajectories
- [PII Anonymization](callbacks/pii-anonymization)
### Custom Callbacks
Create custom callbacks using knowlege of the callback lifecycle as described in [Agent Lifecycle](callbacks/agent-lifecycle).
```python
from agent.callbacks.base import AsyncCallbackHandler
class CustomCallback(AsyncCallbackHandler):
async def on_llm_start(self, messages):
"""Preprocess messages before LLM call"""
# Add custom preprocessing logic
return messages
async def on_llm_end(self, messages):
"""Postprocess messages after LLM call"""
# Add custom postprocessing logic
return messages
async def on_usage(self, usage):
"""Track usage information"""
print(f"Tokens used: {usage.total_tokens}")
```
```
