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.

SkillSpector: 12 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00074 | $0.03923 |
| Opus 5.5 | $0.00030 | $0.01569 |
| Sonnet 5.5 | $0.00015 | $0.00785 |
| Haiku 4.5 | $0.00007 | $0.00392 |
Grade A, and why
hyperframes 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.

HyperFrames — Video Composition Authoring
Write HTML. Render video. Built for agents.
HyperFrames is an open-source video rendering framework where HTML is the source of truth. A composition is an HTML file with data-* attributes for timing, a GSAP timeline for animation, and CSS for appearance. The framework handles clip visibility, media playback, and timeline sync.
Requirements: Node.js >= 22, FFmpeg Install: \Created my-video/ AGENTS.md CLAUDE.md hyperframes.json index.html meta.json package.json
Get started:
-
Install AI coding skills (one-time): npx skills add heygen-com/hyperframes
-
Open this project with your AI coding agent: cd my-video then start Claude Code, Cursor, or your preferred agent
-
Try a starter prompt: "Using /hyperframes, create a 15-second intro about [your topic]" More patterns: hyperframes.heygen.com/guides/prompting
-
Preview in the browser: cd my-video && npm run dev
-
Check the composition: cd my-video && npm run check
-
Render to MP4 when ready: cd my-video && npm run render

Core Concepts
The Composition Model
Every video is a composition — an HTML document with a root element identified by . Inside it, clips (video, audio, img, div elements) are placed on tracks using . Each clip has a and in seconds. The composition has explicit and in pixels.

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.
- 1mo ago First seen · 383 lines · 74 tokens per session scan A ca2522155c07
hyperframes is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (485 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 3,923 once invoked, about $0.0003 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.
