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.

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 | $0.00047 | $0.00927 |
| Opus 5 | $0.00023 | $0.00464 |
| Sonnet 5 | $0.00009 | $0.00185 |
| Haiku 4.5 | $0.00005 | $0.00093 |
Grade A, and why
page-speed 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 10d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Page Speed Optimization
Every funnel page must load fast. Slow pages kill conversions — a 1-second delay reduces conversions by 7%.
Core Web Vitals Targets
| Metric | Target | Impact |
|---|---|---|
| LCP (Largest Contentful Paint) | < 2.5s | Main content visible |
| FID (First Input Delay) | < 100ms | Page is interactive |
| CLS (Cumulative Layout Shift) | < 0.1 | No visual jumping |
| TTFB (Time to First Byte) | < 800ms | Server responds fast |
Required Optimizations
1. Critical CSS Inlining
Inline above-the-fold CSS directly in <head> to eliminate render-blocking:
<head>
<style>
/* Critical: hero, nav, above-fold layout only */
.hero { /* ... */ }
.nav { /* ... */ }
.cta-primary { /* ... */ }
</style>
<!-- Defer the rest -->
<link rel="preload" href="styles.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="styles.css"></noscript>
</head>
2. Image Optimization
<!-- Always include width/height to prevent CLS -->
<img
src="hero.webp"
alt="Descriptive alt text"
width="800"
height="450"
loading="lazy"
decoding="async"
>
<!-- Responsive images with srcset -->
<img
srcset="hero-400.webp 400w, hero-800.webp 800w, hero-1200.webp 1200w"
sizes="(max-width: 600px) 400px, (max-width: 1000px) 800px, 1200px"
src="hero-800.webp"
alt="Descriptive alt text"
width="800"
height="450"
loading="lazy"
>
3. Font Loading
@font-face {
font-family: 'BrandFont';
src: url('brand-font.woff2') format('woff2');
font-display: swap; /* Always include this */
font-weight: 400;
}
<!-- Preload critical fonts -->
<link rel="preload" href="brand-font.woff2" as="font" type="font/woff2" crossorigin>
4. Script Loading
<!-- Defer non-critical scripts -->
<script defer src="analytics.js"></script>
<script defer src="interactions.js"></script>
<!-- Async for independent scripts -->
<script async src="third-party-widget.js"></script>
<!-- Never do this -->
<!-- <script src="blocking.js"></script> in <head> -->
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.

page-speed is a skill published in the GitHub repository ominou5/funnel-architect-plugin (80 stars, last pushed 6mo ago), licensed MIT. It adds 47 tokens to every session and 927 once invoked, about $0.0002 per session on Opus 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.
