HyperFrames is an open-source framework that turns HTML, CSS, media, and timed animations into deterministic MP4 videos. It is used locally, by coding agents, and in hosted authoring workflows to create rendered videos from web-based designs. Its catalogue add-ons provide skills, agents, instructions, hooks, settings, and a plugin for agent-driven video production.

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 | $0.00134 | $0.01823 |
| Opus 5.5 | $0.00054 | $0.00729 |
| Sonnet 5.5 | $0.00027 | $0.00365 |
| Haiku 4.5 | $0.00013 | $0.00182 |
Grade A, and why
oversized-cursor 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Oversized Cursor — the eye-carrier
A deliberately oversized macOS-style pointer that travels the frame as a visible protagonist: it enters from off-screen, walks the viewer's eye to the next point of interest, clicks to cause the next thing that happens, and leaves. Production-proven across multiple launch films.
Why it exists. Big cursor movement is one of the cheapest high-yield motion sources in a launch video: one element, transform-only tweens, and it (1) brings the eye across the screen on scenes that would otherwise read as dead, (2) gives causal ignition to morphs/transitions ("the click did that"), and (3) segments the eye out of a stale state when kicking off a new scene or a complex animation sequence. Bigger is better — an actual-size cursor disappears at video scale.
Size & look (house convention)
- Full-frame scenes:
7cqw(≈134px at 1920). In-mock / small-frame variants:4.6–5.5cqw. Never smaller. - One SVG arrow geometry everywhere. Two proven fills — white body + black stroke, or
black body (
#1c1c1c) + white stroke (1.4px). Pick per scene contrast, keep it constant per film. - Brand-motif cursors (the power play). The macOS arrow is the DEFAULT, not a mandate. When the subject brand has a recognizable cursor identity — a collaborative design tool's colored multiplayer arrow with a name tag (Figma-style), a creative suite's precision crosshair, a distinctive product pointer — use THAT cursor instead: instantly legible brand language for anyone who knows the product. Same laws apply unchanged (oversized scale, physical entry/exit, tip-targeting, click-ignition), and a name-tag variant travels as one rigid unit (tag trailing the arrow). Reach for it only when the motif is genuinely referenceable; a cursor nobody recognizes is just a weird arrow — default back to macOS.
filter: drop-shadow(0 4px 6px rgba(0,0,0,.3)),pointer-events: none,z-indexabove all scene content,will-change: transform.
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.

oversized-cursor is a skill published in the GitHub repository heygen-com/hyperframes (65,314 stars, last pushed today), licensed Apache-2.0. It adds 134 tokens to every session and 1,823 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

gsap
A JavaScript animation framework with shared systems for timelines, easing, and timed value changes. It can animate CSS, SVG, Canvas, WebGL, framework state, and other JavaScript objects, with extensions for tasks such as scroll triggers, drag interactions, motion paths, and text animation.
architecture-diagram
Create a professional, dark-themed software/system architecture diagram as a single self-contained HTML file with inline SVG. Use when asked to visualize system components, layers, services, or how parts of a codebase fit together.
remotion
Use when creating, rendering, and managing programmatic videos using Remotion (React-based video framework). Covers compositions, frame-driven animation, transitions, effects, captions, audio, voiceover, FFmpeg post-production, and professional SaaS-grade motion design.
motiscope-analyze
Analyze a screen recording of an animation to characterize its motion — timing, easing, transforms, and sequencing — so it can be recreated as web code. Use when the user drops or points at a video of an animation (.mp4/.mov/.webm/.mkv/.m4v/.avi/.gif) and says things like "I want this animation on my site", "recreate…
motiscope-rebuild-site
Rebuild a whole landing page / multi-section website from a screen recording that scrolls or walks through it. Use when the user has a recording of an ENTIRE page (not a single animation) and wants the full page recreated — layout, sections, copy, design system, and scroll animations. Orchestrates analyze (measured…
motiscope-recreate
Recreate an analyzed animation as working web code — GSAP (JavaScript), CSS/Web Animations, Framer Motion (React), or Lottie/SVG. Use after motiscope-analyze, or when the user asks to "build/recreate this animation in ". Reads the motiscope animation spec and emits a runnable component.
