feat(copilot): migrate to GitHub Copilot native structure

David Crutchfieldrequested to merge
david.crutchfield/ai-arcade-demo:feature/copilot-migration into main
  • Add .github/copilot-instructions.md with repository-wide context
  • Create 4 prompt files in .github/prompts/ (refresh, recap, commit-message, copy-setup)
  • Add path-specific instructions for src/games/ files
  • Update README.md to reference GitHub Copilot as primary AI assistant
  • Update AGENTS.md with new file locations and prompt file references
  • Add MIGRATION.md documenting the complete migration process
  • Add .github/README.md with comprehensive Copilot configuration guide

This migration reorganizes the project from Claude Code-focused to GitHub Copilot native structure while maintaining backwards compatibility. The new structure uses GitHub's standard .github/ directory and supports:

  • Automatic loading of repository instructions in VS Code
  • Reusable prompt files accessible via Copilot Chat
  • Path-specific instructions that auto-apply to matching files
  • Full compatibility with AGENTS.md for other AI assistants

Original .claude/commands/ and CLAUDE.md preserved for compatibility.
