Chris reviews the latest GitHub changelog including CodeQL updates, GPT-5.1 Codex Max preview, GitHub MCP server tool-specific configuration, and Enterprise Server 3.19 GA. He then explores the major VS Code December release featuring Agent HQ, background agents with git worktrees, sub-agents, and custom agents for organizations, while continuing to build custom agents for a game MCP server project.

Chris continues building custom agents for the software development life cycle. After reviewing the changelog including Copilot Spaces updates and assigning issues to Copilot via API, he explores the awesome-copilot repository for agent inspiration, brainstorms SDLC agent ideas like test writers and security reviewers, and live-builds a GitHub Actions workflow agent with a companion instructions file.

Chris dives into Copilot custom agents and custom instructions for the turn-based game MCP server project. After reviewing the changelog including enterprise bring-your-own-key support and Claude Opus 4.5, he restructures copilot-instructions.md, creates meta instruction files for writing instructions and agents, and explores plan mode for iterating on agent designs.

Chris catches up on several weeks of GitHub releases, including new models including GPT-5.1, GPT-5.1 Codex, and GPT-5.1 Codex Mini, MCP registry controls, and isolated sub-agents. He then returns to the turn-based game MCP server project, using Copilot's agent mode to diagnose and fix a dependency upgrade failure.

In this episode, we review the latest GitHub changelog including remote MCP server support for coding agent and Copilot code review on mobile. We use the Playwright MCP server with Copilot agent mode to debug and fix UI issues in the Octo Arcade project, discuss the differences between ask, edit, and agent modes in VS Code, and explore MCP server concepts like tools, prompts, and resources.

In this stream, Chris catches up on several weeks of GitHub updates including the remote MCP server preview and Copilot coding agent for business users. The live coding session demonstrates adding internationalization to the Copilot Airways app using Copilot coding agent, custom VS Code chat modes for planning, and agent mode in Xcode for iOS development.

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.

The Copilot coding agent can be triggered directly from a Copilot Chat session in Visual Studio Code, not just from GitHub Issues. This video shows how to use the GitHub chat participant in ask mode to delegate an ad-hoc refactoring task—standardizing naming conventions across the 'Copilot Airways' codebase—without interrupting your current workflow. Copilot outlines a plan for your approval, creates a pull request with documentation updates, runs linting and build checks in the background, and waits for the 'Approve and Run' gate before the final review.

In this stream, Chris builds a GitHub CLI extension (gh-demo) in Go from scratch using a spec-driven development approach with Copilot Agent Mode. Topics include bootstrapping a VS Code workspace with Copilot, test-driven development for a hydrate subcommand, and setting up GitHub Actions CI.
