SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires puppeteer-core, google-genai, transformers, torch, soundfile, numpy, elevenlabs, and includes scripts (resource) and assets (resource) components.

What problem does it solve? Turning a merged pull request into a clear, shareable video explanation normally requires manual scripting, recording, and editing. This Skill automates the entire pipeline: it reads a GitHub PR via the gh CLI, designs a story from the diff, generates narration audio and background music, builds animated scenes, and renders a finished MP4. ## Core Features & Use Cases - PR Ingest via gh CLI: Pulls PR title, body, diff, commits, files, and +/- stats, plus contributor avatars for an optional credits scene — no website scraping involved. - Deterministic Pipeline Stages: Story design, audio synthesis (HeyGen, ElevenLabs, or local Kokoro TTS), caption grouping, scene composition, and final assembly are driven by scripts and subagents with validation gates at each step. - Styled Output: Uses the claude design preset with code-window, before-after, and diff-highlight scenes; supports landscape, portrait, and square aspect ratios. - Use Case: A developer advocate wants a 60-second changelog video for PR #1187. They provide the PR URL, confirm the brief, and the pipeline produces a narrated explainer video showing what shipped and why. ## Quick Start Ask the assistant to turn the GitHub pull request at a given URL into a short explainer video, then answer the one-round brief about angle, audience, and length.

Frequently Asked Questions about pr-to-video

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I turn a GitHub pull request into a video?▼

Provide a PR URL, an owner/repo#N reference, or say "this PR" inside a checked-out repo. The pipeline reads the PR with the gh CLI, designs a story from the diff, generates voiceover and background music, builds scenes, and renders an MP4.

What inputs does the pr-to-video workflow accept?▼

It accepts only GitHub pull requests: a full PR URL, an <owner>/<repo>#<N> reference, or "this PR" in a checked-out repository. Marketing sites, general websites, and plain text topics are routed to other skills instead.

Does PR video generation work without API keys?▼

Yes. Without HeyGen or ElevenLabs keys it falls back to local Kokoro TTS, and without a Gemini key it generates BGM locally with MusicGen. The gh CLI must still be authenticated to read the PR.

Can it make videos from private GitHub repositories?▼

Yes, as long as gh auth status passes with an account that has access to the private repository. If gh returns an auth or not-found error, the pipeline stops and reports the exact stderr rather than fabricating PR contents.

What video formats and lengths does it support?▼

It targets up to roughly 3 minutes with a sweet spot of 30-90 seconds, and supports 16:9 landscape (1920x1080), 9:16 portrait (1080x1920), and 1:1 square (1080x1080) aspect ratios. Longer exhaustive walkthroughs are routed to a different skill.

Why did the rendered video come out silent?▼

A silent render means voice wavs were not wired into the assembly, usually because prep was run without the audio_meta.json flag. Re-run prep with --audio-meta ./audio_meta.json and reassemble; the scripts print a CRITICAL banner when this wiring breaks.
