Field feedback from a raw-API agent build (join-the-world-flow): the catalog blurb's word 'animatics' encodes the PNG-slideshow architecture the skill body explicitly forbids — an agent routing by the blurb concludes the shipped behavior is frames-as-pictures. Reworded to 'reconstructed motion (frames read as states, not slides)' across all catalog surfaces (skill frontmatter, CLAUDE.md, README, skills.mdx, hyperframes router, figma guide). Also codifies the stronger doctrine that build demonstrated as storyboard rule 10: when every frame is the same product UI in successive states, rebuild the app as live DOM (Phase-3 for stateful parts, real pixels for static chrome — code what changes state, freeze what doesn't) and perform frame deltas as interactions instead of tweens. Spec §5.1 records the escalation + field origin. Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4:
npx hyperframes render ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
