JamesandClaude Opus 4.6 b8149abef5 chore(skills): rename compose-video → hyperframes-compose, captions → hyperframes-captions

Namespace skill names with `hyperframes-` prefix for clearer identity in
OSS contexts where users may have other skills installed.

Updates skill directories, SKILL.md frontmatter, CLAUDE.md, README.md,
CLI build script, init command, and project template.

Hyperframes

Skills — USE THESE FIRST

This repo ships skills that are installed globally via npx hyperframes skills (runs automatically during hyperframes init). Always use the appropriate skill instead of writing code from scratch or fetching external docs.

HyperFrames Skills (from this repo)

Skill	Invoke with	When to use
hyperframes-compose	`/hyperframes-compose`	Creating ANY HTML composition — videos, animations, title cards, overlays. Contains required HTML structure, `class="clip"` rules, GSAP timeline patterns, and rendering constraints.
hyperframes-captions	`/hyperframes-captions`	Building tone-adaptive captions from whisper transcripts — style detection, per-word styling, positioning.

GSAP Skills (from greensock/gsap-skills)

Skill	Invoke with	When to use
gsap-core	`/gsap-core`	`gsap.to()`, `from()`, `fromTo()`, easing, duration, stagger, defaults
gsap-timeline	`/gsap-timeline`	Timeline sequencing, position parameter, labels, nesting, playback
gsap-performance	`/gsap-performance`	Performance best practices — transforms over layout props, will-change, batching
gsap-plugins	`/gsap-plugins`	ScrollTrigger, Flip, Draggable, SplitText, and other GSAP plugins
gsap-scrolltrigger	`/gsap-scrolltrigger`	Scroll-linked animations, pinning, scrub, triggers
gsap-utils	`/gsap-utils`	`gsap.utils` helpers — clamp, mapRange, snap, toArray, wrap, pipe

Why this matters

The skills encode HyperFrames-specific patterns (e.g., required class="clip" on all timed elements, GSAP timeline registration via window.__GSAP_TIMELINE, data-* attribute semantics) that are NOT in generic web docs. Skipping the skills and writing from scratch will produce broken compositions.

Rules

When creating or modifying HTML compositions → invoke /hyperframes-compose BEFORE writing any code
When adding captions → invoke /hyperframes-captions BEFORE writing any code
When writing GSAP animations → invoke /gsap-core and /gsap-timeline BEFORE writing any code
When optimizing animation performance → invoke /gsap-performance BEFORE making changes

Installing skills

npx hyperframes skills          # install all to Claude, Gemini, Codex
npx hyperframes skills --claude # Claude Code only
npx skills add greensock/gsap-skills  # alternative: via skills CLI

Project Overview

Open-source video rendering framework: write HTML, render video.

packages/
  cli/       → hyperframes CLI (create, preview, lint, render)
  core/      → Types, parsers, generators, linter, runtime, frame adapters
  engine/    → Seekable page-to-video capture engine (Puppeteer + FFmpeg)
  producer/  → Full rendering pipeline (capture + encode + audio mix)
  studio/    → Browser-based composition editor UI

Development

pnpm install    # Install dependencies
pnpm build      # Build all packages
pnpm test       # Run tests

Key Concepts

Compositions are HTML files with data-* attributes defining timeline, tracks, and media
Frame Adapters bridge animation runtimes (GSAP, Lottie, CSS) to the capture engine
Producer orchestrates capture → encode → audio mix into final MP4
BeginFrame rendering uses HeadlessExperimental.beginFrame for deterministic frame capture
