KAgent OpenAI Agents SDK Integration

OpenAI Agents SDK integration for KAgent with A2A (Agent-to-Agent) protocol support, session management, and optional skills integration.

Quick Start

from kagent.openai import KAgentApp
from agents.agent import Agent

# Create your OpenAI agent
agent = Agent(
    name="Assistant",
    instructions="You are a helpful assistant.",
    tools=[my_tool],  # Optional
)

# Create KAgent app
app = KAgentApp(
    agent=agent,
    agent_card={
        "name": "my-openai-agent",
        "description": "My OpenAI agent",
        "version": "0.1.0",
        "capabilities": {"streaming": True},
        "defaultInputModes": ["text"],
        "defaultOutputModes": ["text"]
    },
    kagent_url="http://localhost:8083",
    app_name="my-agent"
)

# Run
fastapi_app = app.build()
# uvicorn run_me:fastapi_app

Agent with Skills

Skills provide domain expertise through filesystem-based instruction files and helper tools (read/write/edit files, bash execution). We provide a function to load all skill-related tools. Otherwise, you can select the ones you need by importing from kagent.openai.tools.

from agents.agent import Agent
from kagent.openai import get_skill_tools

tools = [my_custom_tool]
tools.extend(get_skill_tools("./skills"))

agent = Agent(
    name="SkillfulAgent",
    instructions="Use skills and tools when appropriate.",
    tools=tools,
)

See skills README for skill format and structure.

Session Management

Sessions persist conversation history in KAgent backend:

from agents.agent import Agent
from agents.run import Runner
from kagent.openai._session_service import KAgentSession
import httpx

client = httpx.AsyncClient(base_url="http://localhost:8083")
session = KAgentSession(
    session_id="conversation_123",
    client=client,
    app_name="my-agent",
)

agent = Agent(name="Assistant", instructions="Be helpful")
result = await Runner.run(agent, "Hello!", session=session)

Local Development

Test without KAgent backend using in-memory mode:

app = KAgentApp(
    agent=agent,
    agent_card=agent_card,
    kagent_url="http://localhost:8083",
    app_name="test-agent"
)

fastapi_app = app.build_local()  # In-memory, no persistence

Deployment

Standard Docker deployment:

FROM python:3.13-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY agent.py .
CMD ["uvicorn", "agent:fastapi_app", "--host", "0.0.0.0", "--port", "8000"]

Set KAGENT_API_URL and KAGENT_GATEWAY_URL to connect to kagent.

Architecture

Component	Purpose
KAgentApp	FastAPI application builder with A2A support
KAgentSession	Session persistence via KAgent REST API
OpenAIAgentExecutor	Executes agents with event streaming

Environment Variables

KAGENT_API_URL - KAgent control-plane API URL
KAGENT_GATEWAY_URL - KAgent A2A and MCP gateway URL
LOG_LEVEL - Logging level (default: INFO)
