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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00037 | $0.00871 |
| Opus 5.5 | $0.00015 | $0.00348 |
| Sonnet 5.5 | $0.00007 | $0.00174 |
| Haiku 4.5 | $0.00004 | $0.00087 |
Grade A, and why
orbit-card 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 27d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Orbit Card
One centred feature card with a circular cut-out framing a dot sphere. The card enters from the right (0.25–1.80 s), holds with a subtle bob and depth drift, orbits a full turn around the sphere's centre (smoothstep between 4.97 and 5.97 s), and exits left (7.35–8.55 s). The camera path and card F-curves are exported from the approved Blender rig at 30 fps and interpolated; the sphere keeps its own translation and a constant spin. Title, description, accent and the orbit angle are variables; 180° and 720° work without touching keys.
Composition id: orbit-card. Duration 10 s at 30 fps, 1920×1080.

Install
Install with npx hyperframes add orbit-card; by default the files above land under compositions/orbit-card/. Then mount the block from the host index.html:
<div
data-composition-id="orbit-card"
data-composition-src="compositions/orbit-card/orbit-card.html"
data-start="0"
data-duration="10"
data-track-index="1"
data-width="1920"
data-height="1080"
></div>
Render with custom values by targeting the composition file directly:
npx --yes [email protected] render 'compositions/orbit-card/orbit-card.html' --variables '{"feature1Title":"Always in sync","feature1Desc":"Changes reach every screen the moment they happen."}'
Variables
Read at runtime via window.__hyperframes.getVariables(); declared on the composition root as data-composition-variables (single-quoted attribute, plain JSON).
| id | type | default | label / range |
|---|---|---|---|
feature1Title |
string | "Always in sync" |
Card title max 28 chars |
feature1Desc |
string | "Changes reach every screen the moment they happen." |
Card description max 110 chars |
feature1Accent |

Card accent |

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.

orbit-card is a skill published in the GitHub repository heygen-com/hyperframes (65,314 stars, last pushed today), licensed Apache-2.0. It adds 37 tokens to every session and 871 once invoked, about $0.0001 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 2026-09-20.
