Mechanism

When It Triggers · How It Works · What It Produces

Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.

Trigger

When a user supplies a GitHub PR (URL, owner/repo#N, or 'this PR' in a checked-out repo) and wants a code-change explainer video (changelog, feature reveal, fix, refactor walkthrough). Not for product promo or no-PR topic explainers.

Working Mechanism

  • Orchestrates a 7-step workflow: setup → ingest PR via gh → design system → storyboard/script → audio → visual design → frames → render.
  • Uses npx hyperframes CLI and node scripts to fetch PR diff/commits, build HyperFrames composition, dispatch frame workers, and render MP4.
  • Delegates design/motion rules to sub-agents and referenced skills (hyperframes-core, hyperframes-animation, hyperframes-creative, media-use).

Result

A code-change explainer video (renders/video.mp4) with storyboard, script, captions, contributor credits, and diff-driven visuals from the PR.

Use Cases

Two Typical Use Cases

Scenario 01

Announce merged feature via PR video

A dev relations engineer needs to announce a new feature merged via PR #342 in acme/sdk. They run the skill with the PR ref; it fetches the diff, plans a feature-reveal storyboard, generates narration and claude-styled frames, and renders a 2-minute explainer MP4. The team shares it on release day, saving hours of manual screen-recording and reaching non-engineers clearly.

Scenario 02

Refactor walkthrough for OSS PR

An open-source maintainer wants a refactor walkthrough for PR #88 that cleaned up legacy modules. The skill ingests commits and files, builds a credits close with contributor avatars, and outputs a changelog-style video. It helps onboard new contributors by visualizing the change instead of dumping a raw diff, improving project transparency and documentation.
