What AI Agent Architectures Are Supported?

The ai-agents-for-beginners repository implements nine distinct architectural patterns across multiple code samples. Each pattern solves different orchestration challenges, from simple linear processing to complex multi-agent collaboration.

Sequential Orchestration

Sequential orchestration creates a linear pipeline where one agent's output becomes the next agent's input. This pattern works best for step-wise refinement tasks like content editing or multi-stage analysis.

In 14-microsoft-agent-framework/code-samples/14-sequential.ipynb, the SequentialBuilder class constructs these workflows:

from agent_framework import SequentialBuilder, ChatMessage

# Two simple agents (front-desk & concierge)

front_desk_agent = await provider.create_agent(
    instructions="Recommend attractions for a city."
)
concierge_agent = await provider.create_agent(
    instructions="Rate the front-desk recommendation."
)

# Build the linear pipeline

workflow = (
    SequentialBuilder()
    .participants([front_desk_agent, concierge_agent])
    .build()
)

# Run it

result = await workflow.run("I want a weekend in Barcelona")
print(result)   # → combined recommendation + expert rating

The sequential pattern ensures deterministic processing order, making it predictable and easy to debug.

Concurrent (Fan-Out/Fan-In) Orchestration

Concurrent orchestration runs multiple specialized agents in parallel and aggregates their results. This pattern dramatically improves performance when sub-tasks are independent, such as gathering travel information from different domains.

The 14-microsoft-agent-framework/code-samples/14-concurrent.ipynb notebook demonstrates the ConcurrentBuilder:

from agent_framework import ConcurrentBuilder

# Three specialized agents

attractions = await provider.create_agent(instructions="List attractions.")
dining = await provider.create_agent(instructions="Suggest restaurants.")
history = await provider.create_agent(instructions="Give historical context.")

workflow = (
    ConcurrentBuilder()
    .participants([attractions, dining, history])
    .build()
)

result = await workflow.run("Travel to Kyoto")
print(result)  # → list of parallel suggestions merged into one response

By executing agents simultaneously, concurrent workflows reduce latency from the sum of individual tasks to the duration of the slowest agent plus merge overhead.

Handoff Orchestration

Handoff orchestration enables dynamic routing where an agent transfers control to a specialist when requests exceed its scope. This pattern creates flexible systems that scale expertise without overwhelming primary agents.

The 14-microsoft-agent-framework/code-samples/14-handoff.ipynb notebook implements this with HandoffBuilder and HandoffUserInputRequest:

from agent_framework import HandoffBuilder, HandoffUserInputRequest

# Primary support agent

support = await provider.create_agent(
    instructions="Handle generic travel queries."
)

# Specialist agents

visa = await provider.create_agent(instructions="Answer visa questions.")
refund = await provider.create_agent(instructions="Process refunds.")

workflow = (
    HandoffBuilder()
    .initial_agent(support)
    .add_handoff(
        request=HandoffUserInputRequest(
            trigger="visa",  # keyword that triggers handoff

            target_agent=visa,
        )
    )
    .add_handoff(
        request=HandoffUserInputRequest(
            trigger="refund",
            target_agent=refund,
        )
    )
    .build()
)

print(await workflow.run("I need a refund for my flight"))

Handoff patterns excel in customer service scenarios where specialized knowledge is distributed across multiple agents.

Conditional Workflow

Conditional workflows branch execution paths based on runtime decisions, such as user intent classification. This pattern adds decision-making intelligence to agent systems.

The 14-microsoft-agent-framework/code-samples/14-conditional-workflow.ipynb notebook demonstrates condition-based routing.

Middleware Pattern

Middleware inserts reusable processing steps—logging, validation, transformation—around agent calls without modifying core agent logic.

The 14-microsoft-agent-framework/code-samples/14-middleware.ipynb notebook shows how to wrap agents with cross-cutting concerns.

Multi-Agent Workflow (Complex Pipelines)

Multi-agent workflows combine multiple orchestration primitives to model end-to-end production scenarios. The 08-multi-agent/code_samples/workflows-agent-framework/python/01.python-agent-framework-workflow-ghmodel-basic.ipynb notebook demonstrates content creation with quality gates, merging sequential, concurrent, and conditional patterns into unified pipelines.

Alternative Framework: Semantic Kernel

Beyond the Microsoft Agent Framework, ai-agents-for-beginners supports Semantic Kernel—a lightweight, prompt-engineered alternative for building AI agents.

The 02-explore-agentic-frameworks/code_samples/02-semantic-kernel.ipynb notebook demonstrates this approach:

import semantic_kernel as sk

kernel = sk.Kernel()
kernel.import_skill_from_prompt(
    skill_name="travel_planner",
    prompt="You are a travel planner. Provide a 3-day itinerary for {city}.",
)

result = kernel.run(
    skill_name="travel_planner",
    input="Paris"
)
print(result)

Semantic Kernel offers a simpler entry point for developers who prefer direct prompt engineering over the structured orchestration patterns of MAF.

Agentic Protocols: MCP and A2A

The repository extends beyond single-framework examples to demonstrate industry-standard protocols for agent interoperability:

• Model Context Protocol (MCP): Standardized context sharing between agents and tools
• Agent-to-Agent (A2A) Protocol: Direct communication patterns for multi-agent systems

These implementations appear in 11-agentic-protocols/code_samples/11-mcp-agent-framework.ipynb and 11-agentic-protocols/code_samples/11-a2a-agent-framework.ipynb, positioning ai-agents-for-beginners as a resource for building interoperable, future-proof agent systems.

Frequently Asked Questions

What is the Microsoft Agent Framework?

The Microsoft Agent Framework (MAF) is a Python and .NET library for building structured AI agent workflows. It provides builder classes like SequentialBuilder, ConcurrentBuilder, and HandoffBuilder that encapsulate common orchestration patterns. The framework integrates with Azure AI Foundry and supports both local development and cloud deployment.

How does Semantic Kernel differ from the Microsoft Agent Framework?

Semantic Kernel offers a lighter, more flexible approach focused on prompt engineering and skill composition. While MAF emphasizes structured orchestration patterns with explicit workflow builders, Semantic Kernel treats agents as modular skills that can be composed dynamically. Choose Semantic Kernel for rapid prototyping and MAF for production workflows requiring clear execution guarantees.

Can I combine multiple orchestration patterns in one workflow?

Yes. The 08-multi-agent samples demonstrate composite workflows that merge sequential, concurrent, and conditional patterns. For example, a content creation pipeline might use concurrent agents to research multiple topics, a conditional branch to apply quality gates, and sequential agents to refine and format the final output. The MultiAgentBuilder and pipeline composition APIs support this flexibility.

What are MCP and A2A protocols, and why do they matter?

MCP (Model Context Protocol) standardizes how agents share context with tools and services, while A2A (Agent-to-Agent Protocol) defines direct communication patterns between independent agents. These protocols matter because they enable interoperability: agents built with different frameworks or by different teams can collaborate without tight coupling. The 11-agentic-protocols samples show practical implementations using both standards.
