Attached tools enable specific functionalities like internet browsing or code execution within the agent environment. These tools are created using the Superagent client library and can include functionality for browsing the web, executing code, or accessing third-party APIs. The system allows for structured outputs and supports multiple data types including structured CSV and JSON files, as well as unstructured PDF and text documents.
The platform's workflow structure allows for sequences of agents running in specific orders, with output from one agent passed to the next in the sequence. This modular approach enables the creation of sophisticated systems for various tasks, while the underlying architecture supports multiple vector databases and external tools through interfaces like Pinecone and Weaviate.
The Superagent framework constantly evolves based on community feedback, incorporating core principles of active learning, flexibility, and collaboration between humans and AI agents. This development approach aims to create more autonomous and adaptable AI systems that can scale with foundation model improvements while maintaining meaningful human collaboration.
Building an AI assistant with Superagent begins with configuring essential components through the framework's REST API. The setup process involves creating a language model instance and an agent configuration, then linking these elements together. Here's a detailed breakdown of the development workflow:
Superagent supports multiple programming languages via client libraries:
Python: superagent-py
Node/TypeScript: superagent-js (maintained by the community)
Swift: Maintained by the community
The development process starts with setting up environment variables for API keys and URLs. For example, in Python, you'll need:
import os
from superagent.client import Superagent
client = Superagent(
<pre><code>base_url="https://api.beta.superagent.sh",
token=os.environ["SUPERAGENT_API_KEY"]
</code></pre>
)
The framework requires a language model provider, typically OpenAI. Here's how to configure it:
llm = client.llm.create(request={
<pre><code>"provider": "OPENAI",
"apiKey": os.environ["OPENAI_API_KEY"]
</code></pre>
})
An assistant is created with specific attributes:
agent = client.agent.create(
<pre><code>name="Chat Assistant",
description="My first Assistant",
type="SUPERAGENT",
avatar="https://myavatar.com/homanp.png",
is_active=True,
initial_message="Hi there! How can I help you?",
llm_model="GPT_3_5_TURBO_16K_0613",
prompt="You are a helpful AI Assistant"
</code></pre>
)
Superagent supports various tools, including a browser tool:
client.agent.add_tool(agent_id=agent.data.id, tool_type="BROWSER", tool_metadata={"return_direct": True})
To process user input, you'll use the constructed agent:
client.agent.invoke(agent_id=agent.data.id, input_text="What's the weather like today?", stream=False, session_id="my_session")
For local development, follow these steps:
Clone the repository and navigate to /libs/ui
Install Supabase CLI and create a project
Start the local Supabase project
Run database migrations
Set authentication with passwordless methods or GitHub OAuth
The application can be accessed at http://localhost:3000. The environment requires specific variables including API keys and URLs. This local development environment mirrors the production deployment setup provided by Vercel, ensuring consistent development and staging experiences.
To deploy a Superagent application, the development team must set up Supabase UI and handle authentication through passwordless methods or GitHub OAuth. Development occurs in a structured environment that supports multiple vector databases and external tools, with the architecture designed for efficient agent execution through advanced techniques including Server-Sent Events (SSE), concurrency, and workflow orchestration.
Local development requires cloning the repository and navigating to the /libs/ui directory. The process includes creating an environment file by copying .env.example, setting mandatory environment variables, creating a virtual environment, installing dependencies with poetry, starting Supabase with supabase start, and generating the Prisma schema. The server runs on http://127.0.0.1:8000, accessible at http://127.0.0.1:8000/api/v1.
The Supabase project requires specific setup including authentication setup through passwordless methods or GitHub OAuth. Development involves creating a new GitHub OAuth app, copying the CLIENT_ID and CLIENT_SECRET, and configuring the callback URL. The frontend and backend environments require several environment variables including Supabase URL, anonymous key, storage name, segment write key, and API endpoints for various services.
For deployment, the application needs detailed configuration including database details, JWT secret, vector store configuration, and API keys for various services. The setup requires specific environment variables for operation, including details for OpenAI API, database connection, and third-party service integrations. The framework supports multiple architectures through its flexible deployment options, including Docker, Render, and Replit, while the underlying infrastructure leverages FastAPI, Prefect, and Vercel for efficient execution and management.
