Beginning August 25, a free three-part live series on Microsoft Reactor will teach participants to build and deploy multi-agent applications using the Microsoft Foundry Toolkit for VS Code. This initiative aims to streamline AI agent development by integrating all necessary tools within the IDE, reducing the typical context-switching and lengthy feedback loops. The first session, led by Junjie Li, introduces the toolkit's workflow, covering agent creation, model configuration, local debugging, and deployment. The second session, with Bethany Jepchumba, focuses on building a single-purpose agent that translates technical updates into executive summaries. The third session, presented by Shivam Goyal, escalates to a multi-agent workflow, creating a "Resume → Job Fit Evaluator" that analyzes résumés and job descriptions, identifies gaps, and suggests learning roadmaps. Attendees will learn about orchestration patterns and agent-to-agent handoffs in multi-agent systems. The series emphasizes hands-on building, with a companion GitHub repository supporting over 50 languages for participants to follow along. Registration for the series provides access to all three live sessions and their recordings, ensuring comprehensive learning even if attendance is missed. This program offers a practical approach to building sophisticated AI agents efficiently within a unified development environment.
