VS Code Learn | DEMO - Build your first app with agent mode

A walkthrough demo of VS Code's GitHub Copilot agent mode (plan mode) to build a URL shortener from scratch. The demo covers using plan mode to outline requirements, answering clarifying questions from the agent, switching to autopilot for implementation, steering the agent mid-task (e.g., adding a dark theme), and running multiple sessions simultaneously. The project uses Python, FastAPI, SQLite, uv for dependency management, and a minimal vanilla HTML frontend.
