In this live stream, we explore building a 3D tic-tac-toe visualization using Three.js and Copilot coding agent, demo MCP elicitation for gathering game preferences, and discuss the importance of context engineering when working with AI tools. We also cover GitHub changelog highlights including path-scoped custom instructions for Copilot code review and agents.md support.

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.

In this live stream, we continue building a turn-based game MCP server, implementing MCP elicitation to gather user preferences and consolidating duplicate tool calls into cleaner abstractions. We also recap the latest GitHub changelog including npm trusted publishing with OIDC, Claude Opus 4.1, and Copilot coding agent updates.

In this episode, we recap the latest GitHub changelog including GitHub Spark entering public preview and coding agent support for instructions.md files. We introduce the 'Build for the love of code' hackathon, prototype a rubber duck debugging app with GitHub Spark, and build an MCP server from scratch using TypeScript while exploring tools, prompts, and resources.

In this stream, Chris recaps announcements from Microsoft Build, reviews three weeks of GitHub changelog updates, and does a deep dive into Copilot coding agent using the Copilot Airways demo app. Topics include assigning issues to Copilot, reviewing AI-generated pull requests, MCP integration with Notion, and best practices for writing well-scoped GitHub issues.

Chris continues exploring Copilot Agent Mode and custom instructions by building a memory sequence game for the GitHub CLI extension project in Go. The changelog segment covers GitHub CLI accessibility improvements, Copilot Code Review expanding to all languages, Copilot Autofix updates, and the introduction of Copilot premium requests.

This episode dives deep into Copilot custom instructions — what they are, how to write them, and why they matter for guiding AI-assisted development. Chris reviews the GitHub Changelog including the credential revocation API, CodeQL improvements, and the GitHub Models playground's new prompt improvement feature, then live codes a higher/lower game for a Go-based GitHub CLI extension using Agent Mode with detailed custom instructions.

In this episode, Chris reviews the GitHub Changelog covering organization-level Copilot custom instructions, CodeQL for Actions workflow security analysis, Copilot Code Review language expansion, secret scanning alert dismissals, and GitHub Mobile updates. The coding segment tackles theme switching for the Copilot Airways web app and a Tailwind CSS upgrade using GitHub Codespaces and Copilot Agent Mode.

Chris live-codes a GitHub-themed brick breaker walkthrough using Copilot agent mode, demonstrating how prompt framing, context, and custom instructions shape AI-generated output.

Chris explores GitHub Models as an AI prototyping playground, demonstrates Copilot on the command line for learning Linux commands, and shows off a Cosmos DB-backed leaderboard for the OctoSnap game.
