Engineering a Local-First Agentic Podcast Studio: A Deep Dive into Multi-Agent Orchestration
The transition from standalone Large Language Models (LLMs) to Agentic Orchestration marks the next frontier in AI development. We are moving away from simple "prompt-and-response" cycles toward a paradigm where specialized, autonomous units—AI Agents—collaborate to solve complex, multi-step problems. As a Technology Evangelist, my focus is on building these production-grade systems entirely on the edge, ensuring privacy, speed, and cost-efficiency. This technical guide explores the architecture and implementation of The AI Podcast Studio. This project demonstrates the seamless integration of the Microsoft Agent Framework, Local Small Language Models (SLMs), and VibeVoice to automate a complete tech podcast pipeline. I. The Strategic Intelligence Layer: Why Local-First? At the core of our studio is a Local-First philosophy. While cloud-based LLMs are powerful, they introduce friction in high-frequency, creative pipelines. By using Ollama as a model manager, we run SLMs like Qwen-3-8B directly on user hardware. 1. Architectural Comparison: Local vs. Cloud Choosing the deployment environment is a fundamental architectural decision. For an agentic podcasting workflow, the edge offers distinct advantages: Dimension Local Models (e.g., Qwen-3-8B) Cloud Models (e.g., GPT-5.2) Latency Zero/Ultra-low: Instant token generation without network "jitter". Variable: Dependent on network stability and API traffic. Privacy Total Sovereignty: Creative data and drafts never leave the local device. Shared Risk: Data is processed on third-party servers. Cost Zero API Fees: One-time hardware investment; free to run infinite tokens. Pay-as-you-go: Costs scale with token count and frequency of calls. Availability Offline: The studio remains functional without an internet connection. Online Only: Requires a stable, high-speed connection. 2. Reasoning and Tool-Calling on the Edge To move beyond simple chat, we implement Reasoning Mode, utilizing Chain-of-Thought (CoT) prompting. This allows our local agents to "think" through the podcast structure before writing. Furthermore, we grant them "superpowers" through Tool-Calling, allowing them to execute Python functions for real-time web searches to gather the latest news. II. The Orchestration Engine: Microsoft Agent Framework The true complexity of this project lies in Agent Orchestration—the coordination of specialized agents to work as a cohesive team. We distinguish between Agents, who act as "Jazz Musicians" making flexible decisions, and Workflows, which act as the "Orchestra" following a predefined score. 1. Advanced Orchestration Patterns Drawing from the WorkshopForAgentic architecture, the studio utilizes several sophisticated patterns: Sequential: A strict pipeline where the output of the Researcher flows into the Scriptwriter. Concurrent (Parallel): Multiple agents search different news sources simultaneously to speed up data gathering. Handoff: An agent dynamically "transfers" control to another specialist based on the context of the task. Magentic-One: A high-level "Manager" agent decides which specialist should handle the next task in real-time. III. Implementation: Code Analysis (Workshop Patterns) To maintain a production-grade codebase, we follow the modular structure found in the WorkshopForAgentic/code directory. This ensures that agents, clients, and workflows are decoupled and maintainable. 1. Configuration: Connecting to Local SLMs The first step is initializing the local model client using the framework's Ollama integration. # Based on WorkshopForAgentic/code/config.py from agent_framework.ollama import OllamaChatClient # Initialize the local client for Qwen-3-8B # Standard Ollama endpoint on localhost chat_client = OllamaChatClient( model_id="qwen3:8b", endpoint="http://localhost:11434" ) 2. Agent Definition: Specialized Roles Each agent is a ChatAgent instance defined by its persona and instructions. # Based on WorkshopForAgentic/code/agents.py from agent_framework import ChatAgent # The Researcher Agent: Responsible for web discovery researcher_agent = client.create_agent( name="SearchAgent", instructions="You are my assistant. Answer the questions based on the search engine.", tools=[web_search], ) # The Scriptwriter Agent: Responsible for conversational narrative generate_script_agent = client.create_agent( name="GenerateScriptAgent", instructions=""" You are my podcast script generation assistant. Please generate a 10-minute Chinese podcast script based on the provided content. The podcast script should be co-hosted by Lucy (the host) and Ken (the expert). The script content should be generated based on the input, and the final output format should be as follows: Speaker 1: …… Speaker 2: …… Speaker 1: …… Speaker 2: …… Speaker 1: …… Speaker 2: …… """ ) 3. Workflow Setup: The Sequential Pipeline For a deterministic production line, we use the WorkflowBuilder to connect our agents. # Based on WorkshopForAgentic/code/workflow_setup.py from agent_framework import WorkflowBuilder # Building the podcast pipeline search_executor = AgentExecutor(agent=search_agent, id="search_executor") gen_script_executor = AgentExecutor(agent=gen_script_agent, id="gen_script_executor") review_executor = ReviewExecutor(id="review_executor", genscript_agent_id="gen_script_executor") # Build workflow with approval loop # search_executor -> gen_script_executor -> review_executor # If not approved, review_executor -> gen_script_executor (loop back) workflow = ( WorkflowBuilder() .set_start_executor(search_executor) .add_edge(search_executor, gen_script_executor) .add_edge(gen_script_executor, review_executor) .add_edge(review_executor, gen_script_executor) # Loop back for regeneration .build() ) IV. Multimodal Synthesis: VibeVoice Technology The "Future Bytes" podcast is brought to life using VibeVoice, a specialized technology from Microsoft Research designed for natural conversational synthesis. Conversational Rhythm: It automatically handles natural turn-taking and speech cadences. High Efficiency: By operating at an ultra-low 7.5 Hz frame rate, it significantly reduces the compute power required for high-fidelity audio. Scalability: The system supports up to 4 distinct voices and can generate up to 90 minutes of continuous audio. V. Observability and Debugging: DevUI Building multi-agent systems requires deep visibility into the agentic "thinking" process. We leverage DevUI, a specialized web interface for testing and tracing: Interactive Tracing: Developers can watch the message flow and tool-calling in real-time. Automatic Discovery: DevUI auto-discovers agents defined within the project structure. Input Auto-Generation: The UI generates input fields based on workflow requirements, allowing for rapid iteration. VI. Technical Requirements for Edge Deployment Deploying this studio locally requires specific hardware and software configurations to handle simultaneous LLM and TTS inference: Software: Python 3.10+, Ollama, and the Microsoft Agent Framework. Hardware: 16GB+ RAM is the minimum requirement; 32GB is recommended for running multiple agents and VibeVoice concurrently. Compute: A modern GPU/NPU (e.g., NVIDIA RTX or Snapdragon X Elite) is essential for smooth inference. Final Perspective: From Coding to Directing The AI Podcast Studio represents a significant shift toward Agentic Content Creation. By mastering these orchestration patterns and leveraging local EdgeAI, developers move from simply writing code to directing entire ecosystems of intelligent agents. This "local-first" model ensures that the future of creativity is private, efficient, and infinitely scalable.

We have reached a critical inflection point in AI development. Within the Microsoft Foundry ecosystem, the core value proposition of "Agents" is shifting decisively—moving from passive content generation to active task execution and process automation. These are no longer just conversational interfaces. They are intelligent entities capable of connecting models, data, and tools to actively execute complex business logic. To support this evolution, Microsoft has introduced a powerful suite of capabilities: the Microsoft Agent Framework for sophisticated orchestration, the Agent V2 SDK, and integrated Microsoft Foundry VSCode Extensions. These innovations provide the tooling necessary to bridge the gap between theoretical research and secure, scalable enterprise landing. But how do you turn these separate components into a cohesive business solution? That is the challenge we address today. This post dives into the practical application of these tools, demonstrating how to connect the dots and transform complex multi-agent concepts into deployed reality. The Scenario: Recruitment through an "Agentic Lens" Let’s ground this theoretical discussion with a real-world scenario that perfectly models a multi-agent environment: The Recruitment Process. By examining recruitment through an agentic lens, we can identify distinct entities with specific mandates: The Recruiter Agent: Tasked with setting boundary conditions (job requirements) and preparing data retrieval mechanisms (interview questions). The Applicant Agent: Objective is to process incoming queries and synthesize the best possible output to meet the recruiter's acceptance criteria. Phase 1: Design Achieving Orchestration via Microsoft Foundry Workflows To bridge the gap between our scenario and technical reality, we start with Foundry Workflows. Workflows serves as the visual integration environment within Foundry. It allows you to build declarative pipelines that seamlessly combine deterministic business logic with the probabilistic nature of autonomous AI agents. By adopting this visual, low-code paradigm, you eliminate the need to write complex orchestration logic from scratch. Workflows empowers you to coordinate specialized agents intuitively, creating adaptive systems that solve complex business problems collaboratively. Visually Orchestrating the Cycle Microsoft Foundry provides an intuitive, web-based drag-and-drop interface. This canvas allows you to integrate specialized AI agents alongside standard procedural logic blocks, transforming abstract ideas into executable processes without writing extensive glue code. To translate our recruitment scenario into a functional workflow, we follow a structured approach: Agent Prerequisites: We pre-configure our specialized agents within Foundry. We create a Recruiter Agent (prompted to generate evaluation criteria) and an Applicant Agent (prompted to synthesize responses). Orchestrating the Interaction: We drag these nodes onto the board and define the data flow. The process begins with the Recruiter generating questions, piping that output directly as input for the Applicant agent. Adding Business Logic: A true workflow requires decision-making. We introduce control flow logic, such as IF/ELSE conditional blocks, to evaluate the recruiter's questions based on predefined criteria. This allows the workflow to branch dynamically—if satisfied, the candidate answers the questions; if not, the questions are regenerated. Alternative: YAML Configuration For developers who prefer a code-first approach or wish to rapidly replicate this logic across environments, Foundry allows you to export the underlying YAML. kind: workflow trigger: kind: OnConversationStart id: trigger_wf actions: - kind: SetVariable id: action-1763742724000 variable: Local.LatestMessage value: =UserMessage(System.LastMessageText) - kind: InvokeAzureAgent id: action-1763736666888 agent: name: HiringManager input: messages: =System.LastMessage output: autoSend: true messages: Local.LatestMessage - kind: Question variable: Local.Input id: action-1763737142539 entity: StringPrebuiltEntity skipQuestionMode: SkipOnFirstExecutionIfVariableHasValue prompt: Boss, can you confirm this ? - kind: ConditionGroup conditions: - condition: =Local.Input="Yes" actions: - kind: InvokeAzureAgent id: action-1763744279421 agent: name: ApplyAgent input: messages: =Local.LatestMessage output: autoSend: true messages: Local.LatestMessage - kind: EndConversation id: action-1763740066007 id: if-action-1763736954795-0 id: action-1763736954795 elseActions: - kind: GotoAction actionId: action-1763736666888 id: action-1763737425562 id: "" name: HRDemo description: "" Simulating the End-to-End Process Once constructed, Foundry provides a robust, built-in testing environment. You can trigger the workflow with sample input data to simulate the end-to-end cycle. This allows you to debug hand-offs and interactions in real-time before writing a single line of application code. Phase 2: Develop From Cloud Canvas to Local Code with VSCode Foundry Workflows excels at rapid prototyping. However, a visual UI is rarely sufficient for enterprise-grade production. The critical question becomes: How do we integrate these visual definitions into a rigorous Software Development Lifecycle (SDLC)? While the cloud portal is ideal for design, enterprise application delivery happens in the local IDE. The Microsoft Foundry VSCode Extension bridges this gap. This extension allows developers to: Sync: Pull down workflow definitions from the cloud to your local machine. Inspect: Review the underlying logic in your preferred environment. Scaffold: Rapidly generate the underlying code structures needed to run the flow. This accelerates the shift from "understanding" the flow to "implementing" it. Phase 3: Deploy Productionizing Intelligence with the Microsoft Agent Framework Once the multi-agent orchestration has been validated locally, the final step is transforming it into a shipping application. This is where the Microsoft Agent Framework shines as a runtime engine. It natively ingests the declarative Workflow definitions (YAML) exported from Foundry. This allows artifacts from the prototyping phase to be directly promoted to application deployment. By simply referencing the workflow configuration libraries, you can "hydrate" the entire multi-agent system with minimal boilerplate. Here is the code required to initialize and run the workflow within your application. Note - Check the source code https://github.com/microsoft/Agent-Framework-Samples/tree/main/09.Cases/MicrosoftFoundryWithAITKAndMAF Summary: The Journey from Conversation to Action Microsoft Foundry is more than just a toolbox; it is a comprehensive solution designed to bridge the chasm between theoretical AI research and secure, scalable enterprise applications. In this post, we walked through the three critical stages of modern AI development: Design (Low-Code): Leveraging Foundry Workflows to visually orchestrate specialized agents (Recruiter vs. Applicant) mixed with deterministic business rules. Develop (Local SDLC): Utilizing the VSCode Extension to break down the barriers between the cloud canvas and the local IDE, enabling seamless synchronization and debugging. Deploy (Native Runtime): Using the Microsoft Agent Framework to ingest declarative YAML, realizing the promise of "Configuration as Code" and eliminating tedious logic rewriting. By following this path, developers can move beyond simple content generation and build adaptive, multi-agent systems that drive real business value.

AI-assisted development has grown far beyond simple code suggestions. GitHub Copilot now supports multiple AI models, each optimized for different workflows, from quick edits to deep debugging to multi-step agentic tasks that generate or modify code across your entire repository. As developers, this flexibility is powerful… but only if we know how to choose the right model at the right time. In this guide, I’ll break down: Why model selection matters The four major categories of development tasks A simplified, developer-friendly model comparison table Enterprise considerations and practical tips This is written from the perspective of real-world customer conversations, GitHub Copilot demos, and enterprise adoption journeys Why Model Selection Matters GitHub Copilot isn’t tied to a single model. Instead, it offers a range of models, each with different strengths: Some are optimized for speed Others are optimized for reasoning depth Some are built for agentic workflows Choosing the right model can dramatically improve: The quality of the output The speed of your workflow The accuracy of Copilot’s reasoning The effectiveness of Agents and Plan Mode Your usage efficiency under enterprise quotas Model selection is now a core part of modern software development, just like choosing the right library, framework, or cloud service. The Four Task Categories (and which Model Fits) To simplify model selection, I group tasks into four categories. Each category aligns naturally with specific types of models. 1. Everyday Development Tasks Examples: Writing new functions Improving readability Generating tests Creating documentation Best fit: General-purpose coding models (e.g., GPT‑4.1, GPT‑5‑mini, Claude Sonnet) These models offer the best balance between speed and quality. 2. Fast, Lightweight Edits Examples: Quick explanations JSON/YAML transformations Small refactors Regex generation Short Q&A tasks Best fit: Lightweight models (e.g., Claude Haiku 4.5) These models give near-instant responses and keep you “in flow.” 3. Complex Debugging & Deep Reasoning Examples: Analyzing unfamiliar code Debugging tricky production issues Architecture decisions Multi-step reasoning Performance analysis Best fit: Deep reasoning models (e.g., GPT‑5, GPT‑5.1, GPT‑5.2, Claude Opus) These models handle large context, produce structured reasoning, and give the most reliable insights for complex engineering tasks. 4. Multi-step Agentic Development Examples: Repo-wide refactors Migrating a codebase Scaffolding entire features Implementing multi-file plans in Agent Mode Automated workflows (Plan → Execute → Modify) Best fit: Agent-capable models (e.g., GPT‑5.1‑Codex‑Max, GPT‑5.2‑Codex) These models are ideal when you need Copilot to execute multi-step tasks across your repository. GitHub Copilot Models - Developer Friendly Comparison The set of models you can choose from depends on your Copilot subscription, and the available options may evolve over time. Each model also has its own premium request multiplier, which reflects the compute resources it requires. If you're using a paid Copilot plan, the multiplier determines how many premium requests are deducted whenever that model is used. Model Category Example Models (Premium request Multiplier for paid plans) What they’re best at When to Use Them Fast Lightweight Models Claude Haiku 4.5, Gemini 3 Flash (0.33x) Grok Code Fast 1 (0.25x) Low latency, quick responses Small edits, Q&A, simple code tasks General-Purpose Coding Models GPT‑4.1, GPT‑5‑mini (0x) GPT-5-Codex, Claude Sonnet 4.5 (1x) Reliable day‑to‑day development Writing functions, small tests, documentation Deep Reasoning Models GPT-5.1 Codex Mini (0.33x) GPT‑5, GPT‑5.1, GPT-5.1 Codex, GPT‑5.2, Claude Sonnet 4.0, Gemini 2.5 Pro, Gemini 3 Pro (1x) Claude Opus 4.5 (3x) Complex reasoning and debugging Architecture work, deep bug diagnosis Agentic / Multi-step Models GPT‑5.1‑Codex‑Max, GPT‑5.2‑Codex (1x) Planning + execution workflows Repo-wide changes, feature scaffolding Enterprise Considerations For organizations using Copilot Enterprise or Business: Admins can control which models employees can use Model selection may be restricted due to security, regulation, or data governance You may see fewer available models depending on your organization’s Copilot policies Using "Auto" Model selection in GitHub Copilot GitHub Copilot’s Auto model selection automatically chooses the best available model for your prompts, reducing the mental load of picking a model and helping you avoid rate‑limiting. When enabled, Copilot prioritizes model availability and selects from a rotating set of eligible models such as GPT‑4.1, GPT‑5 mini, GPT‑5.2‑Codex, Claude Haiku 4.5, and Claude Sonnet 4.5 while respecting your subscription level and any administrator‑imposed restrictions. Auto also excludes models blocked by policies, models with premium multipliers greater than 1, and models unavailable in your plan. For paid plans, Auto provides an additional benefit: a 10% discount on premium request multipliers when used in Copilot Chat. Overall, Auto offers a balanced, optimized experience by dynamically selecting a performant and cost‑efficient model without requiring developers to switch models manually.

At a recent developer conference, I delivered a session on Legacy Code Rescue using GitHub Copilot App Modernization. Throughout the day, conversations with developers revealed a clear divide: some have fully embraced Agentic AI in their daily coding, while others remain cautious. Often, this hesitation isn't due to reluctance but stems from organizational concerns around security and regulatory compliance. Having witnessed similar patterns during past technology shifts, I understand how these barriers can slow adoption. In this blog, I'll demystify the most common security concerns about GitHub Copilot and explain how its built-in features address them, empowering organizations to confidently modernize their development workflows. GitHub Copilot Model Training A common question I received at the conference was whether GitHub uses your code as training data for GitHub Copilot. I always direct customers to the GitHub Copilot Trust Center for clarity, but the answer is straightforward: “No. GitHub uses neither Copilot Business nor Enterprise data to train the GitHub model.” Notice this restriction also applies to third-party models as well (e.g. Anthropic, Google). GitHub Copilot Intellectual Property indemnification policy A frequent concern I hear is, since GitHub Copilot’s underlying models are trained on sources that include public code, it might simply “copy and paste” code from those sources. Let’s clarify how this actually works: Does GitHub Copilot “copy/paste”? “The AI models that create Copilot’s suggestions may be trained on public code, but do not contain any code. When they generate a suggestion, they are not “copying and pasting” from any codebase.” To provide an additional layer of protection, GitHub Copilot includes a “duplicate detection filter”. This feature helps prevent suggestions that closely match public code from being surfaced. (Note: This duplicate detection currently does not apply to the Copilot coding agent.) More importantly, customers are protected by an Intellectual Property indemnification policy. This means that if you receive an unmodified suggestion from GitHub Copilot and face a copyright claim as a result, Microsoft will defend you in court. GitHub Copilot Data Retention Another frequent question I hear concerns GitHub Copilot’s data retention policies. For organizations on GitHub Copilot Business and Enterprise plans, retention practices depend on how and where the service is accessed from: Access through IDE for Chat and Code Completions: Prompts and Suggestions: Not retained. User Engagement Data: Kept for two years. Feedback Data: Stored for as long as needed for its intended purpose. Other GitHub Copilot access and use: Prompts and Suggestions: Retained for 28 days. User Engagement Data: Kept for two years. Feedback Data: Stored for as long as needed for its intended purpose. For Copilot Coding Agent, session logs are retained for the life of the account in order to provide the service. Excluding content from GitHub Copilot To prevent GitHub Copilot from indexing sensitive files, you can configure content exclusions at the repository or organization level. In VS Code, use the .copilotignore file to exclude files client-side. Note that files listed in .gitignore are not indexed by default but may still be referenced if open or explicitly referenced (unless they’re excluded through .copilotignore or content exclusions). The life cycle of a GitHub Copilot code suggestion Here are the key protections at each stage of the life cycle of a GitHub Copilot code suggestion: In the IDE: Content exclusions prevent files, folders, or patterns from being included. GitHub proxy (pre-model safety): Prompts go through a GitHub proxy hosted in Microsoft Azure for pre-inference checks: screening for toxic or inappropriate language, relevance, and hacking attempts/jailbreak-style prompts before reaching the model. Model response: With the public code filter enabled, some suggestions are suppressed. The vulnerability protection feature blocks insecure coding patterns like hardcoded credentials or SQL injections in real time. Disable access to GitHub Copilot Free Due to the varying policies associated with GitHub Copilot Free, it is crucial for organizations to ensure it is disabled both in the IDE and on GitHub.com. Since not all IDEs currently offer a built-in option to disable Copilot Free, the most reliable method to prevent both accidental and intentional access is to implement firewall rule changes, as outlined in the official documentation. Agent Mode Allow List Accidental file system deletion by Agentic AI assistants can happen. With GitHub Copilot agent mode, the "Terminal auto approve” setting in VS Code can be used to prevent this. This setting can be managed centrally using a VS Code policy. MCP registry Organizations often want to restrict access to allow only trusted MCP servers. GitHub now offers an MCP registry feature for this purpose. This feature isn’t available in all IDEs and clients yet, but it's being developed. Compliance Certifications The GitHub Copilot Trust Center page lists GitHub Copilot's broad compliance credentials, surpassing many competitors in financial, security, privacy, cloud, and industry coverage. SOC 1 Type 2: Assurance over internal controls for financial reporting. SOC 2 Type 2: In-depth report covering Security, Availability, Processing Integrity, Confidentiality, and Privacy over time. SOC 3: General-use version of SOC 2 with broad executive-level assurance. ISO/IEC 27001:2013: Certification for a formal Information Security Management System (ISMS), based on risk management controls. CSA STAR Level 2: Includes a third-party attestation combining ISO 27001 or SOC 2 with additional cloud control matrix (CCM) requirements. TISAX: Trusted Information Security Assessment Exchange, covering automotive-sector security standards. In summary, while the adoption of AI tools like GitHub Copilot in software development can raise important questions around security, privacy, and compliance, it’s clear that existing safeguards in place help address these concerns. By understanding the safeguards, configurable controls, and robust compliance certifications offered, organizations and developers alike can feel more confident in embracing GitHub Copilot to accelerate innovation while maintaining trust and peace of mind.Building Agents with GitHub Copilot SDK: A Practical Guide to Automated Tech Update Tracking
Introduction In the rapidly evolving tech landscape, staying on top of key project updates is crucial. This article explores how to leverage GitHub's newly released Copilot SDK to build intelligent agent systems, featuring a practical case study on automating daily update tracking and analysis for Microsoft's Agent Framework. GitHub Copilot SDK: Embedding AI Capabilities into Any Application SDK Overview On January 22, 2026, GitHub officially launched the GitHub Copilot SDK technical preview, marking a new era in AI agent development. The SDK provides these core capabilities: Production-grade execution loop: The same battle-tested agentic engine powering GitHub Copilot CLI Multi-language support: Node.js, Python, Go, and .NET Multi-model routing: Flexible model selection for different tasks MCP server integration: Native Model Context Protocol support Real-time streaming: Support for streaming responses and live interactions Tool orchestration: Automated tool invocation and command execution Core Advantages Building agentic workflows from scratch presents numerous challenges: Context management across conversation turns Orchestrating tools and commands Routing between models Handling permissions, safety boundaries, and failure modes The Copilot SDK encapsulates all this complexity. As Mario Rodriguez, GitHub's Chief Product Officer, explains: "The SDK takes the agentic power of Copilot CLI and makes it available in your favorite programming language... GitHub handles authentication, model management, MCP servers, custom agents, and chat sessions plus streaming. That means you are in control of what gets built on top of those building blocks." Quick Start Examples Here's a simple TypeScript example using the Copilot SDK: import { CopilotClient } from "@github/copilot-sdk"; const client = new CopilotClient(); await client.start(); const session = await client.createSession({ model: "gpt-5", }); await session.send({ prompt: "Hello, world!" }); And in Python, it's equally straightforward: from copilot import CopilotClient client = CopilotClient() await client.start() session = await client.create_session({ "model": "claude-sonnet-4.5", "streaming": True, "skill_directories": ["./.copilot_skills/pr-analyzer/SKILL.md"] }) await session.send_and_wait({ "prompt": "Analyze PRs from microsoft/agent-framework merged yesterday" }) Real-World Case Study: Automated Agent Framework Daily Updates Project Background agent-framework-update-everyday is an automated system built with GitHub Copilot SDK and CLI that tracks daily code changes in Microsoft's Agent Framework and generates high-quality technical blog posts. System Architecture The project leverages the following technology stack: GitHub Copilot CLI (@github/copilot): Command-line AI capabilities GitHub Copilot SDK (github-copilot-sdk): Programmatic AI interactions Copilot Skills: Custom PR analysis behaviors GitHub Actions: CI/CD automation pipeline Core Workflow The system runs fully automated via GitHub Actions, executing Monday through Friday at UTC 00:00 with these steps: Step Action Description 1 Checkout repository Clone the repo using actions/checkout@v4 2 Setup Node.js Configure Node.js 22 environment for Copilot CLI 3 Install Copilot CLI Install via npm i -g github/copilot 4 Setup Python Configure Python 3.11 environment 5 Install Python dependencies Install github-copilot-sdk package 6 Run PR Analysis Execute pr_trigger_v2.py with Copilot authentication 7 Commit and push Auto-commit generated blog posts to repository Technical Implementation Details 1. Copilot Skill Definition The project uses a custom Copilot Skill (.copilot_skills/pr-analyzer/SKILL.md) to define: PR analysis behavior patterns Blog post structure requirements Breaking changes priority strategy Code snippet extraction rules This skill-based approach enables the AI agent to focus on domain-specific tasks and produce higher-quality outputs. 2. Python SDK Integration The core script pr_trigger_v2.py demonstrates Python SDK usage: from copilot import CopilotClient # Initialize client client = CopilotClient() await client.start() # Create session with model and skill specification session = await client.create_session({ "model": "claude-sonnet-4.5", "streaming": True, "skill_directories": ["./.copilot_skills/pr-analyzer/SKILL.md"] }) # Send analysis request await session.send_and_wait({ "prompt": "Analyze PRs from microsoft/agent-framework merged yesterday" }) 3. CI/CD Integration The GitHub Actions workflow (.github/workflows/daily-pr-analysis.yml) ensures automated execution: name: Daily PR Analysis on: schedule: - cron: '0 0 * * 1-5' # Monday-Friday at UTC 00:00 workflow_dispatch: # Support manual triggers jobs: analyze: runs-on: ubuntu-latest steps: - name: Setup and Run Analysis env: COPILOT_GITHUB_TOKEN: ${{ secrets.COPILOT_GITHUB_TOKEN }} run: | npm i -g github/copilot pip install github-copilot-sdk --break-system-packages python pr_trigger_v2.py Output Results The system automatically generates structured blog posts saved in the blog/ directory with naming convention: blog/agent-framework-pr-summary-{YYYY-MM-DD}.md Each post includes: Breaking Changes (highlighted first) Major Updates (with code examples) Minor Updates and Bug Fixes Summary and impact assessment Latest Advancements in GitHub Copilot CLI Released alongside the SDK, Copilot CLI has also received major updates, making it an even more powerful development tool: Enhanced Core Capabilities Persistent Memory: Cross-session context retention and intelligent compaction Multi-Model Collaboration: Choose different models for explore, plan, and review workflows Autonomous Execution: Custom agent support Agent skill system Full MCP support Async task delegation Real-World Applications Development teams have already built innovative applications using the SDK: YouTube chapter generators Custom GUI interfaces for agents Speech-to-command workflows for desktop apps Games where you compete with AI Content summarization tools These examples showcase the flexibility and power of the Copilot SDK. SDK vs CLI: Complementary, Not Competing Understanding the relationship between SDK and CLI is important: CLI: An interactive tool for end users, providing a complete development experience SDK: A programmable layer for developers to build customized applications The SDK essentially provides programmatic access to the CLI's core capabilities, enabling developers to: Integrate Copilot agent capabilities into any environment Build graphical user interfaces Create personal productivity tools Run custom internal agents in enterprise workflows GitHub handles the underlying authentication, model management, MCP servers, and session management, while developers focus on building value on top of these building blocks. Best Practices and Recommendations Based on experience from the agent-framework-update-everyday project, here are practical recommendations: 1. Leverage Copilot Skills Effectively Define clear skill files that specify: Input and output formats for tasks Rules for handling edge cases Quality standards and priorities 2. Choose Models Wisely Use different models for different tasks: Exploratory tasks: Use more powerful models (e.g., GPT-5) Execution tasks: Use faster models (e.g., Claude Sonnet) Cost-sensitive tasks: Balance performance and budget 3. Implement Robust Error Handling AI calls in CI/CD environments need to consider: Network timeout and retry strategies API rate limit handling Output validation and fallback mechanisms 4. Secure Authentication Management Use fine-grained Personal Access Tokens (PAT): Create dedicated Copilot access tokens Set minimum permission scope (Copilot Requests: Read) Store securely using GitHub Secrets 5. Version Control and Traceability Automated systems should: Log metadata for each execution Preserve historical outputs for comparison Implement auditable change tracking Future Outlook The release of GitHub Copilot SDK marks the democratization of AI agent development. Developers can now: Lower Development Barriers: No need to deeply understand complex AI infrastructure Accelerate Innovation: Focus on business logic rather than underlying implementation Flexible Integration: Embed AI capabilities into any application scenario Production-Ready: Leverage proven execution loops and security mechanisms As the SDK moves from technical preview to general availability, we can expect: Official support for more languages Richer tool ecosystem More powerful MCP integration capabilities Community-driven best practice libraries Conclusion This article demonstrates how to build practical automation systems using GitHub Copilot SDK through the agent-framework-update-everyday project. This case study not only validates the SDK's technical capabilities but, more importantly, showcases a new development paradigm: Using AI agents as programmable building blocks, integrated into daily development workflows, to liberate developer creativity. Whether you want to build personal productivity tools, enterprise internal agents, or innovative AI applications, the Copilot SDK provides a solid technical foundation.

Would you like to generate a swagger.json directly on an MCP server on-the-fly? In many use cases, using remote MCP servers is not uncommon. In particular, if you're using Azure API Management (APIM), Azure API Center (APIC) or Copilot Studio in Power Platform, integrating with remote MCP servers is inevitable.Implementing A2A protocol in NET: A Practical Guide
As AI systems mature into multi‑agent ecosystems, the need for agents to communicate reliably and securely has become fundamental. Traditionally, agents built on different frameworks like Semantic Kernel, LangChain, custom orchestrators, or enterprise APIs do not share a common communication model. This creates brittle integrations, duplicate logic, and siloed intelligence. The Agent‑to‑Agent Standard (A2AS) addresses this gap by defining a universal, vendor‑neutral protocol for structured agent interoperability. A2A establishes a common language for agents, built on familiar web primitives: JSON‑RPC 2.0 for messaging and HTTPS for transport. Each agent exposes a machine‑readable Agent Card describing its capabilities, supported input/output modes, and authentication requirements. Interactions are modeled as Tasks, which support synchronous, streaming, and long‑running workflows. Messages exchanged within a task contain Parts; text, structured data, files, or streams, that allow agents to collaborate without exposing internal implementation details. By standardizing discovery, communication, authentication, and task orchestration, A2A enables organizations to build composable AI architectures. Specialized agents can coordinate deep reasoning, planning, data retrieval, or business automation regardless of their underlying frameworks or hosting environments. This modularity, combined with industry adoption and Linux Foundation governance, positions A2A as a foundational protocol for interoperable AI systems. A2AS in .NET — Implementation Guide Prerequisites • .NET 8 SDK • Visual Studio 2022 (17.8+) • A2A and A2A.AspNetCore packages • Curl/Postman (optional, for direct endpoint testing) The open‑source A2A project provides a full‑featured .NET SDK, enabling developers to build and host A2A agents using ASP.NET Core or integrate with other agents as a client. Two A2A and A2A.AspNetCore packages power the experience. The SDK offers: A2AClient - to call remote agents TaskManager - to manage incoming tasks & message routing AgentCard / Message / Task models - strongly typed protocol objects MapA2A() - ASP.NET Core router integration that auto‑generates protocol endpoints This allows you to expose an A2A‑compliant agent with minimal boilerplate. Project Setup Create two separate projects: CurrencyAgentService → ASP.NET Core web project that hosts the agent A2AClient → Console app that discovers the agent card and sends a message Install the packages from the pre-requisites in the above projects. Building a Simple A2A Agent (Currency Agent Example) Below is a minimal Currency Agent implemented in ASP.NET Core. It responds by converting amounts between currencies. Step 1: In CurrencyAgentService project, create the CurrencyAgentImplementation class to implement the A2A agent. The class contains the logic for the following: a) Describing itself (agent “card” metadata). b) Processing the incoming text messages like “100 USD to EUR”. c) Returning a single text response with the conversion. The AttachTo(ITaskManager taskManager) method hooks two delegates on the provided taskManager - a) OnAgentCardQuery → GetAgentCardAsync: returns agent metadata. b) OnMessageReceived → ProcessMessageAsync: handles incoming messages and produces a response. Step 2: In the Program.cs of the Currency Agent Solution, create a TaskManager , and attach the agent to it, and expose the A2A endpoint. Typical flow: GET /agent → A2A host asks OnAgentCardQuery → returns the card POST /agent with a text message → A2A host calls OnMessageReceived → returns the conversion text. All fully A2A‑compliant. Calling an A2A Agent from .NET To interact with any A2A‑compliant agent from .NET, the client follows a predictable sequence: identify where the agent lives, discover its capabilities through the Agent Card, initialize a correctly configured A2AClient, construct a well‑formed message, send it asynchronously, and finally interpret the structured response. This ensures your client is fully aligned with the agent’s advertised contract and remains resilient as capabilities evolve. Below are the steps implemented to call the A2A agent from the A2A client: Identify the agent endpoint: Why: You need a stable base URL to resolve the agent’s metadata and send messages. What: Construct a Uri pointing to the agent service, e.g., https://localhost:7009/agent. Discover agent capabilities via an Agent Card. Why: Agent Cards provide a contract: name, description, final URL to call, and features (like streaming). This de-couples your client from hard-coded assumptions and enables dynamic capability checks. What: Use A2ACardResolver with the endpoint Uri, then call GetAgentCardAsync() to obtain an AgentCard. Initialize the A2AClient with the resolved URL. Why: The client encapsulates transport details and ensures messages are sent to the correct agent endpoint, which may differ from the discovery URL. What: Create A2AClient using new Uri (currencyCard.Url) from the Agent Card for correctness. Construct a well-formed agent request message. Why: Agents typically require structured messages for roles, traceability, and multi-part inputs. A unique message ID supports deduplication and logging. What: Build an AgentMessage: • Role = MessageRole.User clarifies intent. • MessageId = Guid.NewGuid().ToString() ensures uniqueness. • Parts contains content; for simple queries, a single TextPart with the prompt (e.g., “100 USD to EUR”). Package and send the message. Why: MessageSendParams can carry the message plus any optional settings (e.g., streaming flags or context). Using a dedicated params object keeps the API extensible. What: Wrap the AgentMessage in MessageSendParams and call SendMessageAsync(...) on the A2AClient. Outcome: Await the asynchronous response to avoid blocking and to stay scalable. Interpret the agent response. Why: Agents can return multiple Parts (text, data, attachments). Extracting the appropriate part avoids assumptions and keeps your client robust. What: Cast to AgentMessage, then read the first TextPart’s Text for the conversion result in this scenario. Best Practices 1. Keep Agents Focused and Single‑Purpose Design each agent around a clear, narrow capability (e.g., currency conversion, scheduling, document summarization). Single‑responsibility agents are easier to reason about, scale, and test, especially when they become part of larger multi‑agent workflows. 2. Maintain Accurate and Helpful Agent Cards The Agent Card is the first interaction point for any client. Ensure it accurately reflects: Supported input/output formats Streaming capabilities Authentication requirements (if any) Version information A clean and honest card helps clients integrate reliably without guesswork. 3. Prefer Structured Inputs and Outputs Although A2A supports plain text, using structured payloads through DataPart objects significantly improves consistency. JSON inputs and outputs reduce ambiguity, eliminate prompt‑engineering edge cases, and make agent behavior more deterministic especially when interacting with other automated agents. 4. Use Meaningful Task States Treat A2A Tasks as proper state machines. Transition through states intentionally (Submitted → Working → Completed, or Working → InputRequired → Completed). This gives clients clarity on progress, makes long‑running operations manageable, and enables more sophisticated control flows. 5. Provide Helpful Error Messages Make use of A2A and JSON‑RPC error codes such as -32602 (invalid input) or -32603 (internal error), and include additional context in the error payload. Avoid opaque messages, error details should guide the client toward recovery or correction. 6. Keep Agents Stateless Where Possible Stateless agents are easier to scale and less prone to hidden failures. When state is necessary, ensure it is stored externally or passed through messages or task contexts. For local POCs, in‑memory state is acceptable, but design with future statelessness in mind. 7. Validate Input Strictly Do not assume incoming messages are well‑formed. Validate fields, formats, and required parameters before processing. For example, a currency conversion agent should confirm both currencies exist and the value is numeric before attempting a conversion. 8. Design for Streaming Even if Disabled Streaming is optional, but it’s a powerful pattern for agents that perform progressive reasoning or long computations. Structuring your logic so it can later emit partial TextPart updates makes it easy to upgrade from synchronous to streaming workflows. 9. Include Traceability Metadata Embed and log identifiers such as TaskId, MessageId, and timestamps. These become crucial for debugging multi‑agent scenarios, improving observability, and correlating distributed workflows—especially once multiple agents collaborate. 10. Offer Clear Guidance When Input Is Missing Instead of returning a generic failure, consider shifting the task to InputRequired and explaining what the client should provide. This improves usability and makes your agent self‑documenting for new consumers.AI Toolkit Extension Pack for Visual Studio Code: Ignite 2025 Update

Orchestrating Multi-Agent Intelligence: MCP-Driven Patterns in Agent Framework
Building reliable AI systems requires modular, stateful coordination and deterministic workflows that enable agents to collaborate seamlessly. The Microsoft Agent Framework provides these foundations, with memory, tracing, and orchestration built in. This implementation demonstrates four multi-agentic patterns — Single Agent, Handoff, Reflection, and Magentic Orchestration — showcasing different interaction models and collaboration strategies. From lightweight domain routing to collaborative planning and self-reflection, these patterns highlight the framework’s flexibility. At the core is Model Context Protocol (MCP), connecting agents, tools, and memory through a shared context interface. Persistent session state, conversation thread history, and checkpoint support are handled via Cosmos DB when configured, with an in-memory dictionary as a default fallback. This setup enables dynamic pattern swapping, performance comparison, and traceable multi-agent interactions — all within a unified, modular runtime. Business Scenario: Contoso Customer Support Chatbot Contoso’s chatbot handles multi-domain customer inquiries like billing anomalies, promotion eligibility, account locks, and data usage questions. These require combining structured data (billing, CRM, security logs, promotions) with unstructured policy documents processed via vector embeddings. Using MCP, the system orchestrates tool calls to fetch real-time structured data and relevant policy content, ensuring policy-aligned, auditable responses without exposing raw databases. This enables the assistant to explain anomalies, recommend actions, confirm eligibility, guide account recovery, and surface risk indicators—reducing handle time and improving first-contact resolution while supporting richer multi-agent reasoning. Architecture & Core Concepts The Contoso chatbot leverages the Microsoft Agent Framework to deliver a modular, stateful, and workflow-driven architecture. At its core, the system consists of: Base Agent: All agent patterns—single agent, reflection, handoff and magentic orchestration—inherit from a common base class, ensuring consistent interfaces for message handling, tool invocation, and state management. Backend: A FastAPI backend manages session routing, agent execution, and workflow orchestration. Frontend: A React-based UI (or Streamlit alternative) streams responses in real-time and visualizes agent reasoning and tool calls. Modular Runtime and Pattern Swapping One of the most powerful aspects of this implementation is its modular runtime design. Each agentic pattern—Single, Reflection, Handoff, and Magnetic—plugs into a shared execution pipeline defined by the base agent and MCP integration. By simply updating the .env configuration (e.g., agent_module=handoff), developers can swap in and out entire coordination strategies without touching the backend, frontend, or memory layers. This makes it easy to compare agent styles side by side, benchmark reasoning behaviors, and experiment with orchestration logic—all while maintaining a consistent, deterministic runtime. The same MCP connectors, FastAPI backend, and Cosmos/in-memory state management work seamlessly across every pattern, enabling rapid iteration and reliable evaluation. # Dynamic agent pattern loading agent_module_path = os.getenv("AGENT_MODULE") agent_module = __import__(agent_module_path, fromlist=["Agent"]) Agent = getattr(agent_module, "Agent") # Common MCP setup across all patterns async def _create_tools(self, headers: Dict[str, str]) -> List[MCPStreamableHTTPTool] | None: if not self.mcp_server_uri: return None return [MCPStreamableHTTPTool( name="mcp-streamable", url=self.mcp_server_uri, headers=headers, timeout=30, request_timeout=30, )] Memory & State Management State management is critical for multi-turn conversations and cross-agent workflows. The system supports two out-of-the-box options: Persistent Storage (Cosmos DB) Acts as the durable, enterprise-ready backend. Stores serialized conversation threads and workflow checkpoints keyed by tenant and session ID. Ensures data durability and auditability across restarts. In-Memory Session Store Default fallback when Cosmos DB credentials are not configured. Maintains ephemeral state per session for fast prototyping or lightweight use cases. All patterns leverage the same thread-based state abstraction, enabling: Session isolation: Each user session maintains its own state and history. Checkpointing: Multi-agent workflows can snapshot shared and executor-local state at any point, supporting pause/resume and fault recovery. Model Context Protocol (MCP): Acts as the connector between agents and tools, standardizing how data is fetched and results are returned to agents, whether querying structured databases or unstructured knowledge sources. Core Principles Across all patterns, the framework emphasizes: Modularity: Components are interchangeable—agents, tools, and state stores can be swapped without disrupting the system. Stateful Coordination: Multi-agent workflows coordinate through shared and local state, enabling complex reasoning without losing context. Deterministic Workflows: While agents operate autonomously, the workflow layer ensures predictable, auditable execution of multi-agent tasks. Unified Execution: From single-agent Q&A to complex Magentic orchestrations, every agent follows the same execution lifecycle and integrates seamlessly with MCP and the state store. Multi-Agent Patterns: Workflow and Coordination With the architecture and core concepts established, we can now explore the agentic patterns implemented in the Contoso chatbot. Each pattern builds on the base agent and MCP integration but differs in how agents orchestrate tasks and communicate with one another to handle multi-domain customer queries. In the sections that follow, we take a deeper dive into each pattern’s workflow and examine the under-the-hood communication flows between agents: Single Agent – A simple, single-domain agent handling straightforward queries. Reflection Agent – Allows agents to introspect and refine their outputs. Handoff Pattern – Routes conversations intelligently to specialized agents across domains. Magentic Orchestration – Coordinates multiple specialist agents for complex, parallel tasks. For each pattern, the focus will be on how agents communicate and coordinate, showing the practical orchestration mechanisms in action. Single Intelligent Agent The Single Agent Pattern represents the simplest orchestration style within the framework. Here, a single autonomous agent handles all reasoning, decision-making, and tool interactions directly — without delegation or multi-agent coordination. When a user submits a request, the single agent processes the query using all tools, memory, and data sources available through the Model Context Protocol (MCP). It performs retrieval, reasoning, and response composition in a single, cohesive loop. Communication Flow: User Input → Agent: The user submits a question or command. Agent → MCP Tools: The agent invokes one or more tools (e.g., vector retrieval, structured queries, or API calls) to gather relevant context and data. Agent → User: The agent synthesizes the tool outputs, applies reasoning, and generates the final response to the user. Session Memory: Throughout the exchange, the agent stores conversation history and extracted entities in the configured memory store (in-memory or Cosmos DB). Key Communication Principles: Single Responsibility: One agent performs both reasoning and action, ensuring fast response times and simpler state management. Direct Tool Invocation: The agent has direct access to all registered tools through MCP, enabling flexible retrieval and action chaining. Stateful Execution: The session memory preserves dialogue context, allowing the agent to maintain continuity across user turns. Deterministic Behavior: The workflow is fully predictable — input, reasoning, tool call, and output occur in a linear sequence. Reflection pattern The Reflection Pattern introduces a lightweight, two-agent communication loop designed to improve the quality and reliability of responses through structured self-review. In this setup, a Primary Agent first generates an initial response to the user’s query. This draft is then passed to a Reviewer Agent, whose role is to critique and refine the response—identifying gaps, inaccuracies, or missed context. Finally, the Primary Agent incorporates this feedback and produces a polished final answer for the user. This process introduces one round of reflection and improvement without adding excessive latency, balancing quality with responsiveness. Communication Flow: User Input → Primary Agent: The user submits a query. Primary Agent → Reviewer Agent: The primary generates an initial draft and passes it to the reviewer. Reviewer Agent → Primary Agent: The reviewer provides feedback or suggested improvements. Primary Agent → User: The primary revises its response and sends the refined version back to the user. Key Communication Principles: Two-Stage Dialogue: Structured interaction between Primary and Reviewer ensures each output undergoes quality assurance. Focused Review: The Reviewer doesn’t recreate answers—it critiques and enhances, reducing redundancy. Stateful Context: Both agents operate over the same shared memory, ensuring consistency between draft and revision. Deterministic Flow: A single reflection round guarantees predictable latency while still improving answer quality. Transparent Traceability: Each step—initial draft, feedback, and final output—is logged, allowing developers to audit reasoning or assess quality improvements over time. In practice, this pattern enables the system to reason about its own output before responding, yielding clearer, more accurate, and policy-aligned answers without requiring multiple independent retries. Handoff Pattern When a user request arrives, the system first routes it through an Intent Classifier (or triage agent) to determine which domain specialist should handle the conversation. Once identified, control is handed off directly to that Specialist Agent, which uses its own tools, domain knowledge, and state context to respond. This specialist continues to handle the user interaction as long as the conversation stays within its domain. If the user’s intent shifts — for example, moving from billing to security — the conversation is routed back to the Intent Classifier, which re-assigns it to the correct specialist agent. This pattern reduces latency and maintains continuity by minimizing unnecessary routing. Each handoff is tracked through the shared state store, ensuring seamless context carry-over and full traceability of decisions. Key Communication Principles: Dynamic Routing: The Intent Classifier routes user input to the right specialist domain. Domain Persistence: The specialist remains active while the user stays within its domain. Context Continuity: Conversation history and entities persist across agents through the shared state store. Traceable Handoffs: Every routing decision is logged for observability and auditability. Low Latency: Responses are faster since domain-appropriate agents handle queries directly. In practice, this means a user could begin a conversation about billing, continue seamlessly, and only be re-routed when switching topics — without losing any conversational context or history. Magentic Pattern The Magentic Pattern is designed for open-ended, multi-faceted tasks that require multiple agents to collaborate. It introduces a Manager (Planner) Agent, which interprets the user’s goal, breaks it into subtasks, and orchestrates multiple Specialist Agents to execute those subtasks. The Manager creates and maintains a Task Ledger, which tracks the status, dependencies, and results of each specialist’s work. As specialists perform their tool calls or reasoning, the Manager monitors their progress, gathers intermediate outputs, and can dynamically re-plan, dispatch additional tasks, or adjust the overall workflow. When all subtasks are complete, the Manager synthesizes the combined results into a coherent final response for the user. Key Communication Principles: Centralized Orchestration: The Manager coordinates all agent interactions and workflow logic. Parallel and Sequential Execution: Specialists can work simultaneously or in sequence based on task dependencies. Task Ledger: Acts as a transparent record of all task assignments, updates, and completions. Dynamic Re-planning: The Manager can modify or extend workflows in real time based on intermediate findings. Shared Memory: All agents access the same state store for consistent context and result sharing. Unified Output: The Manager consolidates results into one response, ensuring coherence across multi-agent reasoning. In practice, Magentic orchestration enables complex reasoning where the system might combine insights from multiple agents — e.g., billing, product, and security — and present a unified recommendation or resolution to the user. Choosing the Right Agent for Your Use Case Selecting the appropriate agent pattern hinges on the complexity of the task and the level of coordination required. As use cases evolve from straightforward queries to intricate, multi-step processes, the need for specialized orchestration increases.
