github/copilot-app-for-beginners.

book-app-reviewer

Review changes in samples/book-app-web for accessibility, responsive layout, tests/build validation, and small beginner-safe changes.

check-screenshots-content

Verify GitHub Copilot app screenshots match the course content. Use when running /check-screenshots-content, or when asked to confirm that app- prefixed screenshots in chapter assets folders are consistent with the README labels, button names, menu items, dialog options, and step-by-step instructions that reference them.

create-svg-image

Wrap a raster image in an SVG and overlay a numbered red "step" circle for course screenshots. Use when running /create-svg-image, or when asked to add a numbered callout badge to an image (e.g. a red circle with a "1" pointing at a UI control) that must still render on a GitHub README.

github-copilot-app-automation

Automate and research the GitHub Copilot app desktop experience. Use for driving Copilot App sessions, creating isolated app experiments, mapping app UI/accessibility controls, taking app screenshots, saving PNG captures, optimizing WebP images, testing prompts without submitting, using app/session APIs, canvases, automations, macOS Accessibility, AppleScript, and safe end-to-end Copilot App workflow probes.

overview-video

Rebuild or update the course overview video (about 98 seconds) for this course in videos/overview. Use when running /overview-video, or when asked to refresh the course overview video, add a chapter or feature to it, retake its dark-mode app screenshots, change its copy or timing, add music, or render a new MP4.
