agent framework designed to make AI agent development simple

EzyAgent: A Modern, Simple, and Powerful BaseAgent Framework

Overview

EzyAgent is a next-generation agent framework designed to make AI agent development simple, observable, and reliable. By learning from the limitations of existing frameworks, we've created a solution that prioritizes developer experience while providing enterprise-grade features.

🌟 Key Features

Simple Yet Powerful

from ezyagentsdf import BaseAgent

# Create an agent in one line
agent = BaseAgent("gpt-4")

# Start chatting
response = await agent.chat("Explain quantum computing")


# Add tools easily
@agent.tool
async def search(query: str) -> str:
    """Search the web."""
    return await web_search(query)

First-Class Async Support

# Stream responses
async with BaseAgent() as agent:
    async for message in agent.stream_chat("Write a long story"):
        print(message)
        
# Parallel operations
async def process_queries(queries: List[str]):
    async with BaseAgent() as agent:
        tasks = [agent.chat(q) for q in queries]
        responses = await asyncio.gather(*tasks)

Advanced Logging & Observability

# Comprehensive logging setup
agent.logger.configure(
    format="json",
    outputs={
        "console": {"level": "INFO"},
        "file": {
            "path": "agent.log",
            "level": "DEBUG"
        },
        "cloudwatch": {
            "group": "agents",
            "stream": "production"
        }
    },
    metrics=["tokens", "latency", "costs"],
    trace_requests=True
)

# Access logs and metrics
print(agent.logger.get_metrics())
print(agent.logger.get_recent_traces())

Robust Error Handling

try:
    response = await agent.chat("Complex query")
except AgentError as e:
    print(f"Error Type: {e.error_type}")
    print(f"Provider Error: {e.provider_error}")
    print(f"Context: {e.context}")
    print(f"How to fix: {e.remediation}")
    print(f"Debug trace: {e.debug_info}")

Intelligent State Management

# Built-in memory and state management
agent.memory.save_state("user_preferences", preferences)
agent.memory.add_context("User is a developer")

# Access conversation history
history = agent.memory.get_chat_history()
context = agent.memory.get_relevant_context("query")

# Persistent storage
await agent.memory.save_to_disk("agent_state.json")
await agent.memory.load_from_disk("agent_state.json")

Universal Provider Support

# Easy provider switching
agent = BaseAgent(provider="openai")
agent = BaseAgent(provider="anthropic")
agent = BaseAgent(provider="ollama")

# Multiple providers with fallback
agent = BaseAgent(
    providers=["anthropic", "openai"],
    fallback_strategy="sequential"
)

# Custom provider configuration
agent = BaseAgent(
    provider="openai",
    config={
        "max_retries": 3,
        "timeout": 30,
        "rate_limit": 100
    }
)
