What problem does it solve? Explaining what changed in a pull request to teammates, users, or stakeholders usually means writing release notes or recording a manual walkthrough. This Skill automates that by reading a PR's diff, commits, and contributors via the GitHub CLI and producing a frame-by-frame explainer video with narration, captions, music, and a rendered MP4. ## Core Features & Use Cases - Deterministic PR ingestion: Fetches PR metadata and the full diff with gh (paginated so large PRs don't truncate), resolves shipped versions for merged PRs, and downloads contributor avatars for a credits close. - Storyboard-driven production: Plans the video as a changelog, feature-reveal, fix-explainer, or refactor-walkthrough archetype, then builds each frame as an HTML composition using a fixed code-editorial design system with real diff hunks. - Full audio and render pipeline: Generates TTS narration with word timings, retrieves background music, fetches SFX, builds captions, assembles the timeline, and renders the final MP4 after lint/check validation. - Use Case: A maintainer merges a large feature PR and runs the Skill on owner/repo#1842 to get a narrated 60-second video walking through the key diff hunks, ending with a contributor credits card citing the shipped version. ## Quick Start Turn the pull request at this GitHub URL into a narrated code-change explainer video and render it to an MP4.
