connectonion 0.0.1b4

A simple Python framework for creating AI agents with behavior tracking

ConnectOnion

🚧 Private Beta - ConnectOnion is currently in private beta. Join our waitlist to get early access!

A simple Python framework for creating AI agents that can use tools and track their behavior.

✨ What's New

• 🎯 Function-Based Tools: Just write regular Python functions - no classes needed!
• 🎭 System Prompts: Define your agent's personality and role
• 🔄 Automatic Conversion: Functions become OpenAI-compatible tools automatically
• 📝 Smart Schema Generation: Type hints become function schemas

🚀 Quick Start

Installation

pip install -r requirements.txt

Basic Usage

import os  
from connectonion import Agent

# Set your OpenAI API key
os.environ["OPENAI_API_KEY"] = "your-api-key-here"

# 1. Define tools as simple functions
def search(query: str) -> str:
    """Search for information."""
    return f"Found information about {query}"

def calculate(expression: str) -> float:
    """Perform mathematical calculations."""
    return eval(expression)  # Use safely in production

# 2. Create an agent with tools and personality
agent = Agent(
    name="my_assistant",
    system_prompt="You are a helpful and friendly assistant.",
    tools=[search, calculate]
    # max_iterations=10 is the default - agent will try up to 10 tool calls per task
)

# 3. Use the agent
result = agent.input("What is 25 * 4?")
print(result)  # Agent will use the calculate function

result = agent.input("Search for Python tutorials") 
print(result)  # Agent will use the search function

# 4. View behavior history (automatic!)
print(agent.history.summary())

🔧 Core Concepts

Agent

The main class that orchestrates LLM calls and tool usage. Each agent:

• Has a unique name for tracking purposes
• Can be given a custom personality via system_prompt
• Automatically converts functions to tools
• Records all behavior to JSON files

Function-Based Tools

NEW: Just write regular Python functions! ConnectOnion automatically converts them to tools:

def my_tool(param: str, optional_param: int = 10) -> str:
    """This docstring becomes the tool description."""
    return f"Processed {param} with value {optional_param}"

# Use it directly - no wrapping needed!
agent = Agent("assistant", tools=[my_tool])

Key features:

• Automatic Schema Generation: Type hints become OpenAI function schemas
• Docstring Integration: First line becomes tool description
• Parameter Handling: Supports required and optional parameters
• Type Conversion: Handles different return types automatically

System Prompts

Define your agent's personality and behavior with flexible input options:

# 1. Direct string prompt
agent = Agent(
    name="helpful_tutor",
    system_prompt="You are an enthusiastic teacher who loves to educate.",
    tools=[my_tools]
)

# 2. Load from file (any text file, no extension restrictions)
agent = Agent(
    name="support_agent",
    system_prompt="prompts/customer_support.md"  # Automatically loads file content
)

# 3. Using Path object
from pathlib import Path
agent = Agent(
    name="coder",
    system_prompt=Path("prompts") / "senior_developer.txt"
)

# 4. None for default prompt
agent = Agent("basic_agent")  # Uses default: "You are a helpful assistant..."

Example prompt file (prompts/customer_support.md):

# Customer Support Agent

You are a senior customer support specialist with expertise in:
- Empathetic communication
- Problem-solving
- Technical troubleshooting

## Guidelines
- Always acknowledge the customer's concern first
- Look for root causes, not just symptoms
- Provide clear, actionable solutions

History

Automatic tracking of all agent behaviors including:

• Tasks executed
• Tools called with parameters and results
• Agent responses and execution time
• Persistent storage in ~/.connectonion/agents/{name}/behavior.json

🎯 Example Tools

You can still use the traditional Tool class approach, but the new functional approach is much simpler:

Traditional Tool Classes (Still Supported)

from connectonion.tools import Calculator, CurrentTime, ReadFile

agent = Agent("assistant", tools=[Calculator(), CurrentTime(), ReadFile()])

New Function-Based Approach (Recommended)

def calculate(expression: str) -> float:
    """Perform mathematical calculations."""
    return eval(expression)  # Use safely in production

def get_time(format: str = "%Y-%m-%d %H:%M:%S") -> str:
    """Get current date and time."""
    from datetime import datetime
    return datetime.now().strftime(format)

def read_file(filepath: str) -> str:
    """Read contents of a text file."""
    with open(filepath, 'r') as f:
        return f.read()

# Use them directly!
agent = Agent("assistant", tools=[calculate, get_time, read_file])

The function-based approach is simpler, more Pythonic, and easier to test!

🔨 Creating Custom Tools

from connectonion.tools import Tool

class WeatherTool(Tool):
    def __init__(self):
        super().__init__(
            name="weather",
            description="Get current weather for a city"
        )
    
    def run(self, city: str) -> str:
        # Your weather API logic here
        return f"Weather in {city}: Sunny, 22°C"
    
    def get_parameters_schema(self):
        return {
            "type": "object",
            "properties": {
                "city": {
                    "type": "string",
                    "description": "Name of the city"
                }
            },
            "required": ["city"]
        }

# Use with agent
agent = Agent(name="weather_agent", tools=[WeatherTool()])

🧪 Running Tests

python -m pytest tests/

Or run individual test files:

python -m unittest tests.test_agent

📊 Behavior Tracking

All agent behaviors are automatically tracked and saved to:

~/.connectonion/agents/{agent_name}/behavior.json

Each record includes:

• Timestamp
• Task description
• Tool calls with parameters and results
• Final result
• Execution duration

View behavior summary:

print(agent.history.summary())
# Agent: my_assistant
# Total tasks completed: 5
# Total tool calls: 8
# Total execution time: 12.34 seconds
# History file: ~/.connectonion/agents/my_assistant/behavior.json
# 
# Tool usage:
#   calculator: 5 calls
#   current_time: 3 calls

🔑 Configuration

OpenAI API Key

Set your API key via environment variable:

export OPENAI_API_KEY="your-api-key-here"

Or pass directly to agent:

agent = Agent(name="test", api_key="your-api-key-here")

Model Selection

agent = Agent(name="test", model="gpt-5")  # Default: gpt-5-mini

Iteration Control

Control how many tool calling iterations an agent can perform:

# Default: 10 iterations (good for most tasks)
agent = Agent(name="assistant", tools=[...])

# Complex tasks may need more iterations
research_agent = Agent(
    name="researcher", 
    tools=[search, analyze, summarize, write_file],
    max_iterations=25  # Allow more steps for complex workflows
)

# Simple agents can use fewer iterations for safety
calculator = Agent(
    name="calc", 
    tools=[calculate],
    max_iterations=5  # Prevent runaway calculations
)

# Per-request override for specific complex tasks
result = agent.input(
    "Analyze all project files and generate comprehensive report",
    max_iterations=50  # Override for this specific task
)

When an agent reaches its iteration limit, it returns:

"Task incomplete: Maximum iterations (10) reached."

Choosing the Right Limit:

• Simple tasks (1-3 tools): 5-10 iterations
• Standard workflows: 10-15 iterations (default: 10)
• Complex analysis: 20-30 iterations
• Research/multi-step: 30+ iterations

🛠️ Advanced Usage

Multiple Tool Calls

Agents can chain multiple tool calls automatically:

result = agent.input(
    "Calculate 15 * 8, then tell me what time you did this calculation"
)
# Agent will use calculator first, then current_time tool

Custom LLM Providers

from connectonion.llm import LLM

class CustomLLM(LLM):
    def complete(self, messages, tools=None):
        # Your custom LLM implementation
        pass

agent = Agent(name="test", llm=CustomLLM())

🚧 Current Limitations (MVP)

This is an MVP version with intentional limitations:

• Single LLM provider (OpenAI)
• Synchronous execution only
• JSON file storage only
• Basic error handling
• No multi-agent collaboration

🗺️ Future Roadmap

• Multiple LLM provider support (Anthropic, Local models)
• Async/await support
• Database storage options
• Advanced memory systems
• Multi-agent collaboration
• Web interface for behavior monitoring
• Plugin system for tools
