UniAgent

UniAgent provides a unified agent SDK that normalizes LLM inputs/outputs to a Claude-compatible canonical protocol, with driver adapters for multiple model providers and built-in middleware/observability hooks.

Installation

pip install -e .

Optional observability support:

pip install -e .[otel]

Quick Start

import os

from uniagent import UniAgent

agent = UniAgent(
    provider="claude",
    model="claude-sonnet-4-5-20250929",
    api_key=os.getenv("ANTHROPIC_API_KEY"),
)

response = await agent.run([agent.user("Hello")])

print(response)

Tool Registration

from uniagent import UniAgent

@UniAgent.tool
def get_weather(city: str) -> str:
    """Get weather for a city."""
    return f"Sunny in {city}"

agent = UniAgent(
    provider="claude",
    model="claude-sonnet-4-5-20250929",
    api_key="YOUR_ANTHROPIC_API_KEY",
    tools=[get_weather],
)

Streaming

async for event in agent.stream(messages):
    print(event.event, event.data)
