🎯 Why This Framework?

Before vs After: The Transformation

# 1️⃣ Manually create tools
from azure.ai.projects.agentic import FunctionTool

def weather_tool():
    """Hard-coded tool definition"""
    pass

weather = FunctionTool(weather_tool, ...)

# 2️⃣ Manually register in __init__.py
from .weather import weather_tool
from .stock import stock_tool
# ... repeat for every tool

# 3️⃣ Hard-code agent configuration
agent = ChatAgent(
    name="Weather Agent",
    instructions="Long prompt...",
    tools=[weather, forecast, ...]  # Manual list
)

# 4️⃣ Edit Python for every change
# Want to add a tool? Edit 3+ files
# Want to change prompt? Edit Python
# Want new agent? Write more Python

# 1️⃣ Drop a tool file - auto-discovered!
# tools/weather/humidity.py
@tool(domain="weather", description="...")
def get_humidity(location: str) -> str:
    return f"Humidity: 65%"

# Done! ✨ Automatically registered

# 2️⃣ Drop a YAML file - instant agent!
# agents/weather_agent.yaml
name: "Weather Assistant"
tool_domains: ["weather"]
instructions: |
  You are a weather assistant...

# Done! ✨ Automatically created

# 3️⃣ Launch DevUI
python run_devui.py
# All agents & tools auto-discovered! 🚀

💡 Core Concepts

1. Tools

Tools are Python functions decorated with @tool that provide specific capabilities to agents.

Key Features:

• Automatic discovery via filesystem scanning
• Domain-based organization (weather, stock, email, etc.)
• Tag-based filtering for fine-grained control
• Mock vs real API support

2. Agents

Agents are AI assistants configured via YAML files that automatically discover and use tools.

Key Features:

• Declarative YAML configuration
• Automatic tool attachment based on domains/tags
• Editable prompts without code changes
• Azure OpenAI integration

3. Workflows

Workflows orchestrate multiple agents to solve complex tasks.

Types:

• Sequential: Agents run one after another
• Parallel: Agents run concurrently (fan-out/fan-in)
• Custom: Build complex routing and conditional logic

🛠 Creating Tools

Step 1: Create a Tool File

Create a Python file in the appropriate domain folder:

# tools/weather/humidity.py
from typing import Annotated
from tools._decorators import tool

@tool(
    domain="weather",
    description="Get humidity levels for a location",
    tags=["weather", "humidity", "conditions"],
    mock=True,  # Set to False when using real APIs
)
def get_humidity(
    location: Annotated[str, "The location to check humidity for"]
) -> str:
    """Get humidity percentage for a given location.

    Args:
        location: City name or location string

    Returns:
        Formatted string with humidity information
    """
    # Mock implementation
    return f"Humidity in {location}: 65%"

Step 2: That's It!

The tool is now:

• ✅ Automatically discovered at startup
• ✅ Registered in the tool registry
• ✅ Available to all agents with tool_domains: ["weather"]

No code editing, imports, or registration needed!

Tool Decorator Parameters

@tool(
    domain: str,              # Required: Tool domain (weather, stock, email, etc.)
    name: Optional[str],      # Optional: Tool name (defaults to function name)
    description: Optional[str], # Optional: Description (defaults to docstring)
    tags: Optional[list],     # Optional: Additional tags for filtering
    mock: bool = False,       # Optional: Is this a mock implementation?
    requires_api_key: Optional[str], # Optional: API key environment variable
)

🤖 Creating Agents

Step 1: Create a YAML Configuration

Create a YAML file in the agents/ directory:

# agents/news_agent.yaml
name: "News Assistant"
description: "Provides latest news headlines and articles"

# Tool Discovery - automatically finds matching tools
tool_domains:
  - news

tool_tags:
  - news
  - headlines
  - articles

# Optional: Exclude specific tools
# exclude_tools:
#   - news.experimental_feature

# Agent Instructions (the "prompt")
instructions: |
  You are a news assistant. Provide latest news headlines
  and articles when asked. Always cite your sources and
  present information objectively.

  When users ask about news:
  1. Use the appropriate tool to fetch articles
  2. Summarize key points clearly
  3. Provide source attribution

# Model Configuration - Multi-Provider with Automatic Fallback
model:
  # Provider list (will try in order until one succeeds)
  providers:
    - "openrouter"  # Try OpenRouter first (easiest, no auth issues)
    - "azure"       # Fall back to Azure if available
    - "openai"      # Fall back to OpenAI if available

  # Azure configuration (used if azure provider succeeds)
  endpoint: "https://your-azure-openai.openai.azure.com/"
  deployment: "gpt-4o"
  credential_type: "azure_cli"

  # OpenRouter/OpenAI config loaded from environment:
  # OPENROUTER_API_KEY, OPENROUTER_MODEL, OPENAI_API_KEY

Step 2: Create Domain Tools (if needed)

If the domain doesn't exist, create tools for it:

# tools/news/get_headlines.py
from tools._decorators import tool

@tool(domain="news", description="Get latest news headlines")
def get_headlines(category: str = "general") -> str:
    """Fetch latest news headlines."""
    # Implementation here
    return "Latest headlines..."

Step 3: Restart and Use!

python run_devui.py

The news agent is now automatically:

• ✅ Discovered from the YAML file
• ✅ Created with matching tools attached
• ✅ Available in the DevUI

No Python code editing required!

🏃 Running the System

DevUI (Web Interface)

Launch the development web interface:

python run_devui.py

Features:

• Chat with individual agents
• Test workflows
• View agent capabilities
• Debug tool calls

Python API

Use agents programmatically:

from agents import get_all_agents
import asyncio

async def main():
    # Get all auto-discovered agents
    agents = get_all_agents()

    # Use weather agent
    weather_agent = agents['weather_agent']
    response = await weather_agent.run("What's the weather in Tokyo?")
    print(response)

asyncio.run(main())

Testing

Run the test suites:

# Test tool discovery
python -c "from tools import ToolRegistry; print(ToolRegistry().get_summary())"

# Test agent creation
python test_agent_factory.py

# Test automatic discovery
python test_auto_discovery.py

📚 Examples

Example 1: Simple Agent Query

from agents import get_all_agents
import asyncio

async def main():
    agents = get_all_agents()
    weather_agent = agents['weather_agent']

    response = await weather_agent.run(
        "What's the weather forecast for Seattle this week?"
    )
    print(response)

asyncio.run(main())

Example 2: Sequential Workflow

from agent_framework import SequentialBuilder
from agents import get_all_agents

agents = get_all_agents()
stock_agent = agents['stock_agent']
weather_agent = agents['weather_agent']

workflow = (
    SequentialBuilder()
    .add_agent(stock_agent)
    .add_agent(weather_agent)
    .build()
)

# Execute: stock analysis → weather check
result = await workflow.run("Analyze AAPL and check weather in Cupertino")

Example 3: Parallel Workflow

from agent_framework import ConcurrentBuilder
from agents import get_all_agents

agents = get_all_agents()

workflow = (
    ConcurrentBuilder()
    .participants([agents['stock_agent'], agents['weather_agent']])
    .build()
)

# Both agents run simultaneously
result = await workflow.run("Get AAPL price and Seattle weather")

Example 4: Creating a Custom Tool

# tools/news/search_articles.py
from typing import Annotated
from tools._decorators import tool

@tool(
    domain="news",
    description="Search news articles by keyword",
    tags=["news", "search", "articles"],
    mock=True
)
def search_articles(
    query: Annotated[str, "Search query"],
    days: Annotated[int, "Days to look back"] = 7
) -> str:
    """Search for news articles matching the query."""
    return f"Found 10 articles about '{query}' from last {days} days"

Tool Registry Operations

The ToolRegistry maintains a central registry of all discovered tools with powerful query capabilities:

Core Operations:

• get_tools_by_domain(domain) - Filter by domain (weather, calendar, etc.)
• get_tools_by_tags(tags) - Filter by tags (forecast, event, etc.)
• get_tool(tool_id) - Get specific tool by ID
• list_domains() - Get all available domains
• get_summary() - Get registry statistics

Example:

from tools import ToolRegistry

registry = ToolRegistry()

# Get all weather tools
weather_tools = registry.get_tools_by_domain("weather")
# Returns: [current_weather, forecast]

# Get all tools tagged with "event"
event_tools = registry.get_tools_by_tags(["event"])
# Returns: [create_event, delete_event, list_events]

# Get summary
summary = registry.get_summary()
# {
#   'total_tools': 11,
#   'domains': ['weather', 'calendar', 'stock', 'email'],
#   'tools_by_domain': {...}
# }

⚙️ Configuration

Multi-Provider Support with Automatic Fallback

All agents now support automatic provider fallback - if one provider fails (e.g., Azure auth issues), the system automatically tries the next provider in the list.

How it works:

1. Agent YAML specifies a list of providers to try
2. System attempts each provider in order
3. First successful provider is used
4. If all fail, error is reported

Example configuration:

model:
  providers:
    - "openrouter"  # Try first (easiest, no Azure auth needed)
    - "azure"       # Try second (if Azure CLI is authenticated)
    - "openai"      # Try third (if OpenAI API key is set)

Benefits:

• ✅ No more agent failures due to Azure auth issues
• ✅ Seamless switching between providers
• ✅ Development-friendly (OpenRouter) with production Azure support
• ✅ Zero code changes needed

Supported Providers:

• OpenRouter: Access 100+ models via single API key
• Azure OpenAI: Enterprise-grade Azure integration
• OpenAI: Direct OpenAI API access
