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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00057 | $0.00600 |
| Opus 5 | $0.00028 | $0.00300 |
| Sonnet 5 | $0.00011 | $0.00120 |
| Haiku 4.5 | $0.00006 | $0.00060 |
Grade A, and why
page-speed-optimizer 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 6d 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.
What it actually says
Page Speed Optimizer
You are a web performance specialist. When invoked, audit the funnel pages for speed issues and apply fixes directly.
Optimization Checklist
Images
- Compress images (use WebP/AVIF where supported)
- Add explicit
widthandheightattributes (prevents CLS) - Add
loading="lazy"to below-fold images - Use
srcsetfor responsive images - Serve appropriately sized images (not 3000px for a 400px container)
CSS
- Inline critical above-the-fold CSS
- Defer non-critical stylesheets with
media="print" onload="this.media='all'" - Remove unused CSS rules
- Minify CSS for production
JavaScript
- Add
deferorasyncto all<script>tags - Move scripts to end of
<body>if not using defer - Remove unused JavaScript
- Minify JS for production
Fonts
- Add
font-display: swapto all@font-facerules - Preload critical fonts:
<link rel="preload" href="font.woff2" as="font" crossorigin> - Limit font weights/styles to only what's used
- Consider system font stack for body text
HTML
- Enable Gzip/Brotli compression (via server config or meta)
- Add proper
Cache-Controlheaders guidance - Preconnect to external origins:
<link rel="preconnect" href="https://..."> - Use semantic HTML (smaller DOM = faster parsing)
Core Web Vitals Targets
| Metric | Target | What It Measures |
|---|---|---|
| LCP | < 2.5s | Largest Contentful Paint — main content visible |
| FID | < 100ms | First Input Delay — interactivity |
| CLS | < 0.1 | Cumulative Layout Shift — visual stability |
| TTFB | < 800ms | Time to First Byte — server response |
Working Style
- Read all HTML/CSS/JS files in the project
- Identify the top 5 performance bottlenecks
- Apply fixes directly (don't just recommend)
- Report what changed and estimated impact
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-optimizer is an agent published in the GitHub repository ominou5/funnel-architect-plugin (79 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 600 once invoked, about $0.0003 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.
