What Can You Do with the AI Toolkit Extension Pack?

Build AI Agents Using GitHub Copilot

• Scaffold agent applications using best-practice patterns, tool-calling examples, tracing hooks, and test scaffolds, all powered by Copilot and aligned with the Microsoft Agent Framework.
• Generate agent code in Python or .NET, giving you flexibility to target your preferred runtime.

Build and Customize YAML Workflows

• Design YAML-based workflows in the Foundry portal, then continue editing and testing directly in VS Code.
• To customize your YAML-based workflows, instantly convert it to Agent Framework code using GitHub Copilot. Upgrade from declarative design to code-first customization without starting from scratch.

Visualize Multi-Agent Workflows

• Envision your code-based agent workflows with an interactive graph visualizer that reveals each component and how they connect
• Watch in real-time how each node lights up as you run your agent. Use the visualizer to understand and debug complex agent graphs, making iteration fast and intuitive.

Experiment, Debug, and Evaluate Locally

• Use the Hosted Agents Playground to quickly interact with your agents on your development machine.
• Leverage local tracing support to debug reasoning steps, tool calls, and latency hotspots—so you can quickly diagnose and fix issues.
• Define metrics, tasks, and datasets for agent evaluation, then implement metrics using the Foundry Evaluation SDK and orchestrate evaluations runs with the help of Copilot.

Seamless Integration Across Environments

• Jump from Foundry Portal to VS Code Web for a development environment in your preferred code editor setting.
• Open YAML workflows, playgrounds, and agent templates directly in VS Code for editing and deployment.

How to Get Started

• Install the AI Toolkit extension pack from the VS Code marketplace.
• Install the Azure MCP server extension to leverage GitHub Copilot to interact with your Foundry resources
• Select the AI Toolkit icon on the VS Code sidebar to view and build with your LLMs and agents.
• Select the Foundry extension icon for deeper integration and access to enterprise-grade hosting and evaluation.
• Install the Foundry SDK and review documentation for both AITK and Foundry.
