Rubber Duck Thursdays - Let's build with custom agents (again!)
GitHubChris 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.

Rubber Duck Thursdays - Let's build
GitHubChris 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.

Rubber Duck Thursdays - Let's keep building!
GitHubIn 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.

Rubber Duck Thursdays - Building a turn-based-game MCP server
GitHubIn 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.

Assign issues to GitHub Copilot from the GitHub mobile app
GitHubThe GitHub Copilot coding agent works from anywhere—including your phone. This video demonstrates assigning a GitHub Issue to Copilot directly from the GitHub Mobile app, targeting a GitHub Pages deployment task for the 'Copilot Airways' CI workflow. It then shows how to monitor Copilot's progress, view the session log, and review and approve the resulting pull request entirely from a mobile browser, including the 'Approve and Run' gate that protects GitHub Actions execution.

Assigning Copilot ad-hoc tasks through Copilot chat
GitHubThe 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.

The GitHub Copilot coding agent *NEW*
GitHubGitHub Copilot coding agent lets you assign GitHub Issues to Copilot, which works asynchronously in the background to create and iterate on pull requests. This video walks through assigning a form input validation task on the 'Copilot Airways' demo app, watching Copilot form a plan, generate code, and run linters, builds, and tests to verify quality. It also covers the human-in-the-loop review experience—adding PR comments that Copilot acknowledges and acts on—plus the 'Approve and Run' gate that protects GitHub Actions execution.

Rubber Duck Thursdays - Back to building GitHub CLI Extensions
GitHubIn 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.

Rubber Duck Thursdays - Creating gh-game CLI extension
GitHubDeep dive into GitHub Actions workflows including build, linter, and release pipelines for the GitHub Skyline CLI extension. Chris cuts a live release, then creates a brand new GitHub CLI extension (gh-game) from scratch — building a coin toss game in Go using the Cobra package with help from GitHub Copilot.

Manage your repositories at scale across the enterprise
GitHubIntroduces enterprise repository policies in GitHub, a governance feature that lets administrators restrict repository operations—including visibility changes, creations, deletions, transfers, and naming—across all organizations in an enterprise account. The video also demonstrates repository properties defined at the enterprise level, giving organization admins consistent, inherited property values and requiring them at repository creation time to enforce compliance from day one.
