On June 22, 2026, HeyGen unveiled a new workflow feature called "skills" for its open-source video framework HyperFrames, debuting with "pr-to-video," which automatically converts a GitHub Pull Request (PR) into a short explainer video. The company says it will add a new skill every day going forward.
HyperFrames · One new skill per day
"Nobody reads Pull Requests" — so HeyGen turns them into video
HeyGen's open-source pr-to-video skill lets an AI agent read the code changes in a GitHub PR and render a short explainer video — locally, free, no API key required.

The agent loop: HTML in → MP4 out
"Write HTML. Render video. Built for agents." Video is defined in HTML/CSS/JS and rendered deterministically — the same input always yields the same file.
