What problem does it solve? Turning a merged or proposed pull request into a clear video explanation normally requires manual screen recording, scripting, and editing; this Skill automates that pipeline by reading the PR's diff, commits, and contributors and producing a finished MP4 explainer. ## Core Features & Use Cases - Deterministic PR ingestion: Uses the GitHub CLI (gh) to fetch PR metadata, the full diff (paginated for large PRs), and contributor avatars, with no website capture step. - End-to-end video pipeline: Orchestrates setup, storyboard and script drafting, TTS narration with word timings, BGM/SFX retrieval, frame-by-frame HTML composition building, caption generation, and final MP4 rendering through the HyperFrames CLI. - Code-editorial design system: Applies a fixed code-editorial preset with a navy code surface, rendering real diff hunks through code-* registry blocks (diff, morph, typing) and closing with a contributor credits frame. - Use Case: After merging a feature PR like acme/sdk#1842, ask the agent to turn that PR into a 60-second changelog video; it fetches the diff, drafts a storyboard for approval, generates narration and music, and renders renders/video.mp4. ## Quick Start Turn the pull request at https://github.com/owner/repo/pull/123 into a short code-change explainer video with narration and background music.
