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.

Security

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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/animation-map.mjs, scripts/contrast-report.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HyperFrames

HTML is the source of truth for video. 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.

Approach

Before writing HTML, think at a high level:

  1. What — what should the viewer experience? Identify the narrative arc, key moments, and emotional beats.
  2. Structure — how many compositions, which are sub-compositions vs inline, what tracks carry what (video, audio, overlays, captions).
  3. Timing — which clips drive the duration, where do transitions land, what's the pacing.
  4. Layout — build the end-state first. See "Layout Before Animation" below.
  5. Animate — then add motion using the rules below.

For small edits (fix a color, adjust timing, add one element), skip straight to the rules.

Visual Identity Gate

Check in this order:

  1. DESIGN.md exists in the project? → Read it. Use its exact colors, fonts, motion rules, and "What NOT to Do" constraints.
  2. visual-style.md exists? → Read it. Apply its style_prompt_full and structured fields. (Note: visual-style.md is a project-specific file. visual-styles.md is the style library with 8 named presets — different files.)
  3. User named a style (e.g., "Swiss Pulse", "dark and techy", "luxury brand")? → Read visual-styles.md for the 8 named presets. Generate a minimal DESIGN.md with: ## Style Prompt (one paragraph), ## Colors (3-5 hex values with roles), ## Typography (1-2 font families), ## What NOT to Do (3-5 anti-patterns).
  4. None of the above? → Ask 3 questions before writing any HTML:
    • What's the mood? (explosive / cinematic / fluid / technical / chaotic / warm)
    • Light or dark canvas?
    • Any specific brand colors, fonts, or visual references? Then generate a minimal DESIGN.md from the answers.

Files

What ships with it

38 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
