Rubber Duck Thursdays - Lizard, Spock
In this episode, the team extends the Rock Paper Scissors game to include Lizard and Spock using GitHub Copilot Vision — feeding an image of the game’s relationship diagram directly into Copilot, which interprets it and generates the extended game logic without explicitly naming the game. The stream also adds a hidden flag for the extended mode, demonstrating prompt engineering with Copilot’s multimodal capabilities.
The GitHub changelog review covers Copilot autofix expansion for CodeQL alerts, Claude 3.7 Sonnet availability in Copilot, Docker Compose support in Dependabot, Copilot code review in public preview, and Copilot in Windows Terminal Canary. The latter portion demonstrates Dependabot version updates configured for Go modules and GitHub Actions ecosystems, with a live review of a dependency update pull request. A GitHub Codespaces session is used to verify the gh-skyline CLI extension still works after a dependency bump, and repository settings for auto-deleting branches and auto-merging pull requests are configured.
