Phantasm offers open-source toolkits that allows you to create human-in-the-loop (HITL) workflows for modern AI agents. Phantasm comes with 3 main components that work together to create a seamless HITL experience:

• Server: Coordinating the HITL workflows between humans and AI agents.
• Dashboard: For the human team to monitor and manage the workflows.
• Client: A library to integrate the workflows into your AI agents.

Features

• ✅ Fully open-source and free to use
• ✅ Works out of the box with any AI framework or model
• ✅ Load balancer to distribute the requests to multiple approvers (Beta)
• ✅ Web-based dashboard to manage the approval workflows
• ✅ Easy-to-use client libraries for popular programming languages

How It Works

Phantasm allows you to have an approval layer on top of your AI agents. This means, you're free to use any AI framework or model you see fit. By using Phantasm, you can delay the execution of certain business critical actions by your AI agents until a human approves them.

This is particularly useful in scenarios where the AI agent is not 100% accurate or the cost of making a mistake is high. For example, an AI agent that can automate calendar scheduling. In this case, you can use Phantasm to make sure that the AI agent schedules the right meetings at the right time.

Here's how it works under the hood:

1. Your AI agent sends an approval request to Phantasm's server.
2. Phantasm relays the request to a human approver.
3. The approver reviews the request and either approves or rejects it.
4. Phantasm sends the decision back to the AI agent.

Phantasm can also relay the action parameters to the approvers. This parameters can be modified by the approvers before approving the action. This is useful if there is only a slight mistake in the action parameters that can be corrected by the approvers. This way the action can be approved with some modifications instead of rejected.

Getting Started

The easiest way to get started with Phantasm is by using Docker. There are 2 components that you need to run before you can start using Phantasm: Server and Dashboard. To run these components, first, you need to pull the Docker images of these components.

These Docker images are hosted on GitHub Container Registry: Packages

docker pull ghcr.io/phantasmlabs/phantasm/dashboard:latest
docker pull ghcr.io/phantasmlabs/phantasm/server:latest

After pulling the images, you can run the components with these commands:

docker run -d -p 2515:2515 ghcr.io/phantasmlabs/phantasm/dashboard:latest
docker run -d -p 2505:2505 -p 2510:2510 ghcr.io/phantasmlabs/phantasm/server:latest start

After running the components, you will have access to:

• Dashboard: localhost:2515
• Receiver Server: localhost:2505
• Coordinator Server: localhost:2510

You can use the dashboard to manage the approval workflows by adding a connection to Phantasm's Coordinator Server. The Receiver Server is used to receive the approval requests from the AI agents via Phantasm's client library. Depending on the programming language you use, you can choose the appropriate client library from the list below:

• Python

Best Practices

Error Handling & Fallback Mechanism

Phantasm is designed for real-time approval workflows for AI agents with some non-technical dependencies that could be unpredictable such as the availability of the approvers. Therefore, it is important to have good error handling and fallback mechanisms in place. Here are some edge cases that you should consider before using Phantasm in production:

• No approver is available to monitor and approve the action.
• The approver is not able to approve the action within a certain time frame.
• The approver rejects the action from being executed by the AI agent.

To handle these edge cases, you can use the following strategies:

• Set a timeout for the approval request based on the urgency of the action.
• Create fall-back actions for timed out or rejected approval requests.
• Retry the approval request method if the approver is not available.
• Notify an approver via email if no approver is available at the time.
• Other strategies that are specific to your use case...

Parameters & Context

When sending an approval request using Phantasm, you can also send the action parameters and context to be relayed to the approvers. Most of the time, you want to use this feature to help the approvers make an informed decision. Parameters are usually the input values of the action while the context is the additional information that can help the approvers understand the action better.

Here are some best practices when sending parameters and context:

• Send the parameters generated by the AI agent as an object or dictionary.
• When reviewing the action, make sure the parameters are correct and valid.
• Send the action documentation with parameters explanation in the context.
• Optionally, include context from the end-user such as messages or triggers.
