gh-demo-reel

Capture a visual demo reel for a pull request by recording UI or CLI changes as GIFs, terminal recordings, or screenshots, then attaching the resulting artifacts directly to the PR description.

Adding visual evidence to PR descriptions is best done by capturing observable behavior via screen recordings or GIFs, proving the changes work while following strict secrets safety checks to prevent sensitive data leakage.

You need ffmpeg, ffprobe, vhs, and silicon to record terminal output for a PR, as the capture pipeline relies on these external tools for preflight detection, recording, and stitching artifacts together.

You can use agent-browser to capture UI changes as a GIF, with the pipeline automatically guiding you to a suitable capture tier based on available tooling and your specific project type.

The capture pipeline handles demo artifacts by orchestrating preflight detection, capture, and stitching, then uploading the results or saving them locally for review while enforcing strict safeguards against secrets.

Limitations when generating CLI demo recordings for PRs include strict dependencies on external tools like vhs and silicon, and the pipeline must perform preflight detection to ensure the necessary recording environment is available.
