Overview
What you'll build and learn
Build a retro arcade GitHub Contribution Battle Arena while mastering VS Code Copilot features: context engineering, Plan Mode, Agent Mode, design-first development, and multi-agent workflows.
Teach Copilot about your codebase with workspace instructions, background agents, and Ask mode exploration.
Design architecture before coding — iterate on plans until they're right, then implement with confidence.
Let Copilot scaffold entire features autonomously across multiple files, then iterate with feedback.
Use background and cloud agents for parallel polish — responsive design, error UX, theme variations.
