If you’re looking to empower your AI agents to converse and collaborate with humans effectively, look no further than HumanLayer. This Python toolkit not only facilitates interaction between AI agents and human users, but it also incorporates human oversight for critical tasks, making it a safe choice for integrating AI in tool-based and asynchronous workflows. In this guide, we’ll walk you through how to get started with HumanLayer, explore its key features, and provide troubleshooting tips to ensure a smooth experience.

Getting Started

To begin your journey with HumanLayer, follow these steps:

• Install the HumanLayer Python package:

  pip install humanlayer

• Import and initialize HumanLayer in your project:

  from humanlayer import HumanLayer
  hl = HumanLayer()

• Explore various calling functions. For instance, you can utilize the @hl.require_approval() decorator to ensure that tasks are approved by human operators before execution.

For more detailed instructions, refer to the Getting Started Guide.

Understanding the Code: A Culinary Analogy

The core functionality of HumanLayer can be likened to a culinary process where you follow a recipe to create a dish.

• Ingredients (Functions and Tools): Just like a recipe requires specific ingredients, your HumanLayer setup requires well-defined functions (like sending an email) to perform actions.
• Recipe Steps (Workflows): The steps in a recipe outline how to combine these ingredients in sequence to achieve the end dish, similar to how you would use HumanLayer’s decorators and functions to construct workflows that ensure human oversight.
• Chef’s Approval (Human Oversight): Just as a chef might taste a dish at various stages, your setup allows for human approval before moving forward with potentially impactful actions like sending emails on behalf of users.

Why HumanLayer?

HumanLayer integrates human oversight into AI functions, particularly for high-stakes tasks. Here’s a quick breakdown:

• Low Stakes: Reading public data or sending notifications without sensitive implications.
• Medium Stakes: Tasks like accessing private data or sending structured messages that require defined interactions.
• High Stakes: Functions involving critical operations like sending emails on behalf of users or making changes to important data records. Accurate function calling here is essential.

Key Features

• Require Human Approval for Function Calls: The @hl.require_approval() decorator allows specific functions to wait for human consultation before execution.
• Human as Tool: With hl.human_as_tool(), you can involve a human for advice, feedback, or to resolve uncertainties during the operation.
• OmniChannel Contact: Contact individuals and gather responses from various platforms such as Slack, Email, and Discord.
• Bring your own LLM + Framework: HumanLayer is adaptable and designed to work with any LLM and most tool-calling frameworks.

Troubleshooting Tips

If you encounter any issues while using HumanLayer, here are some common troubleshooting ideas:

• Make sure that all required libraries are installed correctly. Any missing dependencies may cause unexpected errors.
• If you’re facing issues with approval processes, double-check the configurations related to human notification settings.
• For problems with function calls, ensure that your decorators are set up correctly and that there are no typos in your function definitions.
• Utilize the Documentation for detailed instructions on specific functionalities.
