What is hyperframes-scene-builder?

A guide for building HTML, CSS, and JavaScript video scenes with HyperFrames, a render engine, and GSAP, an animation library.

Use it to create or edit compositions, build reusable scene components, render output, and validate frames at specific points in an animation.

It provides project and animation conventions that make scenes easier to render, inspect, revise, and debug.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.01213
Opus 5.5	$0.00025	$0.00485
Sonnet 5.5	$0.00012	$0.00243
Haiku 4.5	$0.00006	$0.00121

Security

Grade A, and why

hyperframes-scene-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

HyperFrames Scene Builder

Use this skill when implementing or revising a HyperFrames scene. This skill assumes HyperFrames is the render engine and the scene source is HTML/CSS/JS.

Project Conventions

Prefer this layout for video projects:

compositions/
renders/
assets/
snapshots/
assembly/
captions/
tools/

Use one composition per meaningful scene or reusable sub-scene. Keep files small enough to inspect and diff.

Composition Rules

Define an explicit composition root with data-composition-id, data-width, data-height, and timing metadata where the project uses it.
Register GSAP timelines under the matching composition ID.
Scope selectors to the composition root when scenes are nested.
Avoid global selectors that can mutate other sub-compositions.
Prefer reusable HTML/CSS components for repeated cards, labels, charts, rings, logo rows, and panels.
Keep media paths relative to the composition project.

GSAP Timeline Rules

Use paused timelines for deterministic seekable animation.
Place important moments at named labels or exact seconds.
Use set for initial state.
Use fromTo when CSS transforms already exist.
Avoid accidental opacity-only transitions when the request asks for physical or material motion.
Avoid bounce/rebound unless the user explicitly asks for it.
Keep final frame stable enough for proof extraction.

Render Loop

Typical commands:

npx hyperframes preview
npx hyperframes lint
npx hyperframes render --composition compositions/scene-name.html --output renders/scene-name.mp4 --fps 24 --quality draft --workers 2

Use higher FPS or quality only when the scene is approved or when testing frame-rate-specific motion.

Visual QA

After rendering:

Extract first-frame, key-beat, and final-frame PNGs.
Compare reference-image scenes against the final frame, not only the opening frame.
Check text fit at desktop/video resolution.
Check that hidden duplicated frames in following scenes are updated.
Check theme colors in CSS, SVG fills/strokes, and inline styles.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
