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 | $0.00039 | $0.01529 |
| Opus 5.5 | $0.00016 | $0.00612 |
| Sonnet 5.5 | $0.00008 | $0.00306 |
| Haiku 4.5 | $0.00004 | $0.00153 |
Grade A, and why
glass-shard-title 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 26d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Glass Shard Title
Voronoi-cut glass panes fly in from depth, rotating, and land as a tiled silhouette of the headline, then fly out past the camera. Each shard is a Sutherland–Hodgman clip of a jittered blob against its Voronoi cell, so the pieces always cover the type. Glass and matcap surfaces get per-fragment fog; the z-flight is decoupled from the ease so shards visibly traverse it. Tile count 1 gives a single pane.
Composition id: glass-shard-title. Duration 12.16 s at 30 fps, 1920×1080.

Install
Install with npx hyperframes add glass-shard-title; by default the files above land under compositions/glass-shard-title/. Then mount the block from the host index.html:
<div
data-composition-id="glass-shard-title"
data-composition-src="compositions/glass-shard-title/glass-shard-title.html"
data-start="0"
data-duration="12.16"
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/glass-shard-title/glass-shard-title.html' --variables '{"headline":"Designed in glass","tileCount":8}'

Read at runtime via window.__hyperframes.getVariables(); declared on the composition root as data-composition-variables (single-quoted attribute, plain JSON).

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.

glass-shard-title is a skill published in the GitHub repository heygen-com/hyperframes (64,542 stars, last pushed today), licensed Apache-2.0. It adds 39 tokens to every session and 1,529 once invoked, about $0.0002 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.
