Rubber Duck Thursdays - Time to build!

2025-09-04

Join us for Rubber Duck Thursdays! A lighthearted and informal stream where we live code on some projects.

In this stream, we explore adding a 3D visualization to the turn-based game MCP server using Three.js, built with help from Copilot coding agent. We demo switching between 2D and 3D views of tic-tac-toe games while playing against the MCP server, and discuss the iterative process of prompting Copilot — including the importance of specifying requirements like piece orientation and camera controls.

We also demo MCP elicitation for gathering game creation preferences, discuss the upcoming blog post on elicitation, and highlight the importance of context engineering when working with AI tools.

The GitHub changelog covers Copilot in Visual Studio August update, path-scoped custom instructions for Copilot code review, agents.md support for coding agent, home dashboard improvements, and CodeQL 2.22.4 updates.

In this live stream, we recap the MCP server elicitation feature and then dive into GitHub Actions fundamentals — building workflows from scratch, covering triggers, jobs, dependencies with needs, matrix builds for cross-platform testing, and workflow_dispatch for manual runs. We also walk through a packed GitHub changelog covering ARM64 runners, GPT-5 in GitHub Models, immutable releases, and GitHub MCP server secret scanning.
