What problem does it solve? Turning a merged or proposed pull request into a clear video explanation normally requires manual scripting, screen recording, and editing. This Skill automates that pipeline: it ingests a PR via the GitHub CLI, plans a narrative from the diff, and renders a finished MP4 explainer. ## Core Features & Use Cases - Deterministic PR ingestion: Fetches PR metadata, the full paginated file list, and the diff via gh, then builds a synthetic capture package with contributor avatars for a credits close. - Storyboard and script generation: Plans changelog, feature-reveal, fix-explainer, or refactor-walkthrough narratives with real diff hunks, then produces narration audio, captions, and background music. - Frame-by-frame HTML video assembly: Dispatches bounded frame workers to build HTML compositions, assembles them into an index, and renders the final MP4 with lint, check, and snapshot verification gates. - Use Case: After merging a large feature PR, point the Skill at owner/repo#123 to produce a narrated walkthrough video highlighting the key diff hunks and crediting contributors. ## Quick Start Turn the pull request at owner/repo#123 into a narrated code-change explainer video and render it as an MP4.
