🚀 Quick Start

Installation

# Create virtual environment
python3 -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install KubeAgentic
pip install kubeagentic

# Or install from source
git clone https://github.com/KubeAgentic-Community/kubeagenticpkg.git
cd kubeagenticpkg
pip install -e ".[dev]"

Create Your First Agent

1. Create a configuration file (my_agent.yaml):

version: "1.0"
agent:
  name: "customer_support_agent"
  description: "A helpful customer support agent"
  
  llm:
    provider: "openai"
    model: "gpt-4"
    temperature: 0.7
    max_tokens: 1000
  
  system_prompt: |
    You are a helpful customer support agent.
    Be friendly, professional, and concise.
  
  tools:
    - name: "search_knowledge_base"
      description: "Search the company knowledge base"
    - name: "create_ticket"
      description: "Create a support ticket"
  
  logging:
    level: "info"

2. Start the API server:

# Using CLI
kubeagentic serve --config my_agent.yaml --port 8000

# Or using Python
from kubeagentic import AgentServer

server = AgentServer.from_yaml("my_agent.yaml")
server.run(host="0.0.0.0", port=8000)

3. Use the API:

import openai

# Point to your KubeAgentic server
client = openai.OpenAI(
    api_key="your-api-key",
    base_url="http://localhost:8000/v1"
)

# Chat with your agent
response = client.chat.completions.create(
    model="customer_support_agent",
    messages=[
        {"role": "user", "content": "How do I reset my password?"}
    ]
)

print(response.choices[0].message.content)

API Endpoints

KubeAgentic provides OpenAI-compatible endpoints:

Chat Completions

POST /v1/chat/completions

{
  "model": "customer_support_agent",
  "messages": [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello!"}
  ],
  "temperature": 0.7,
  "stream": false
}

Streaming

response = client.chat.completions.create(
    model="my_agent",
    messages=[{"role": "user", "content": "Tell me a story"}],
    stream=True
)

for chunk in response:
    print(chunk.choices[0].delta.content, end="")

Health & Monitoring

GET /health          # Liveness check
GET /ready           # Readiness check
GET /metrics         # Prometheus metrics

🔧 Advanced Features

Custom Tools

Create custom tools for your agents:

from kubeagentic.tools import BaseTool
from pydantic import BaseModel, Field

class SearchInput(BaseModel):
    query: str = Field(..., description="Search query")

class SearchTool(BaseTool):
    name = "search"
    description = "Search the web"
    args_schema = SearchInput
    
    async def _arun(self, query: str) -> str:
        # Your search implementation
        results = await search_web(query)
        return results

Register in YAML:

tools:
  - type: "custom"
    class: "my_module.SearchTool"

Multiple Agents

Run multiple agents simultaneously:

from kubeagentic import AgentManager

manager = AgentManager()
manager.load_agent("agent1.yaml")
manager.load_agent("agent2.yaml")

# Access different agents
response = await manager.chat(
    agent_name="agent1",
    message="Hello!"
)

Session Management

Maintain conversation context:

# Create a session
session_id = await manager.create_session(
    agent_name="my_agent",
    user_id="user123"
)

# Continue conversation
response = await manager.chat(
    agent_name="my_agent",
    message="What did we discuss earlier?",
    session_id=session_id
)
