    from agentle.agents.agent import Agent
    from agentle.generations.providers.google import GoogleGenerationProvider

    # Create a simple agent
    agent = Agent(
        name="Quick Start Agent",
        generation_provider=GoogleGenerationProvider(),
        model="gemini-2.5-flash",
        instructions="You are a helpful assistant."

    # Run the agent
    response = agent.run("What are the three laws of robotics?")

    # Print the response
    print(response.text)

## Features

Everything you need for AI agents

Built with developer productivity and type safety in mind, Agentle provides a clean, intuitive API.

### Simple Agent Creation

Build powerful AI agents with minimal code using a clean, intuitive API.

### Composable Architecture

Create sequential pipelines or dynamic teams of specialized agents for complex tasks.

### Tool Integration

Seamlessly connect agents to external tools and functions to perform actions beyond text generation.

### Structured Outputs

Get strongly-typed responses with Pydantic integration for predictable data handling.

### Built-in Observability

Automatic tracing via Langfuse with extensible interfaces for monitoring agent performance.

### Ready for Production

Deploy as APIs (BlackSheep), UIs (Streamlit), or embedded in applications.

### Agent-to-Agent (A2A)

Support for Google's standardized A2A protocol for seamless agent communication.

### Prompt Management

Flexible system for organizing and managing prompts for consistent agent behavior.

### Knowledge Integration

Seamlessly incorporate static knowledge from documents, URLs, or text.

## Examples

See Agentle in action

Here are some examples of what you can build with Agentle.

### Tool Integration

weather_agent.py

    def get_weather(location: str) -> str:
        """
        Get the current weather for a location.

        Args:
            location: The city or location to get weather for

        Returns:
            A string describing the weather
        """
        weather_data = {
            "New York": "Sunny, 75°F",
            "London": "Rainy, 60°F",
            "Tokyo": "Cloudy, 65°F",
            "Sydney": "Clear, 80°F",
        }
        return weather_data.get(location, f"Weather data not available for {location}")

    # Create an agent with a tool
    weather_agent = Agent(
        name="Weather Assistant",
        generation_provider=GoogleGenerationProvider(),
        model="gemini-2.5-flash",
        instructions="You are a helpful assistant that can answer questions about the weather.",
        tools=[get_weather]  # Pass the function as a tool
    )

    # The agent will automatically use the tool when appropriate
    response = weather_agent.run("What's the weather like in Tokyo?")

### Structured Outputs

structured_outputs.py

    from pydantic import BaseModel
    from typing import List, Optional
    from agentle.agents.agent import Agent
    from agentle.generations.providers.google import GoogleGenerationProvider

    # Define your output schema with Pydantic
    class WeatherForecast(BaseModel):
        location: str
        current_temperature: float
        conditions: str
        forecast: List[str]
        humidity: Optional[int] = None

    # Create an agent with structured output
    structured_agent = Agent(
        name="Weather Agent",
        generation_provider=GoogleGenerationProvider(),
        model="gemini-2.5-flash",
        instructions="You are a weather forecasting assistant. Provide accurate forecasts.",
        response_schema=WeatherForecast  # Define the expected response structure
    )

    # Run the agent
    response = structured_agent.run("What's the weather like in San Francisco?")

    # Access structured data with type hints
    weather = response.parsed
    print(f"Weather for: {weather.location}")
    print(f"Temperature: {weather.current_temperature}°C")
    print(f"Conditions: {weather.conditions}")
    print(f"Forecast: {', '.join(weather.forecast)}")
    if weather.humidity:
        print(f"Humidity: {weather.humidity}%")

### Agent Pipelines

agent_pipeline.py

    from agentle.agents.agent import Agent
    from agentle.agents.agent_pipeline import AgentPipeline

    # Create specialized agents
    research_agent = Agent(
        name="Research Agent",
        generation_provider=provider,
        model="gemini-2.5-flash",
        instructions="""You are a research agent focused on gathering information.
        Be thorough and prioritize accuracy over speculation."""
    )

    analysis_agent = Agent(
        name="Analysis Agent",
        generation_provider=provider,
        model="gemini-2.5-flash",
        instructions="""You are an analysis agent that identifies patterns.
        Highlight meaningful relationships and insights from the data."""
    )

    summary_agent = Agent(
        name="Summary Agent",
        generation_provider=provider,
        model="gemini-2.5-flash",
        instructions="""You are a summary agent that creates concise summaries.
        Present key findings in a logical order with accessible language."""
    )

    # Create a pipeline
    pipeline = AgentPipeline(
        agents=[research_agent, analysis_agent, summary_agent],
        debug_mode=True  # Enable to see intermediate steps
    )

    # Run the pipeline
    result = pipeline.run("Research the impact of artificial intelligence on healthcare")
