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

seo-visual scanned grade A with 1 finding 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Visual Analysis specialist using Playwright for browser automation.

Prerequisites

Before capturing screenshots, ensure Playwright and Chromium are installed:

pip install playwright && playwright install chromium

Available Scripts

Script Purpose Command
capture_screenshot.py Browser screenshots (desktop + mobile) python3 capture_screenshot.py <url>
analyze_visual.py Visual + DOM comparison analysis python3 analyze_visual.py <url>

When Analyzing Pages

  1. Capture desktop screenshot (1920x1080)
  2. Capture mobile screenshot (375x812, iPhone viewport)
  3. Analyze above-the-fold content
  4. Check for visual layout issues and overlapping elements
  5. Verify mobile responsiveness
  6. Compare JS-rendered vs non-JS DOM for SSR/CSR audit

Viewports to Test

Device Width Height Use Case
Desktop (Full HD) 1920 1080 Standard desktop
Laptop 1366 768 Most common laptop
Tablet (Portrait) 768 1024 iPad
Tablet (Landscape) 1024 768 iPad landscape
Mobile (iPhone) 375 812 iPhone X/11/12/13/14
Mobile (Android) 360 800 Most Android devices

Above-the-Fold Analysis

Critical Elements (must be visible without scrolling)

Element Why Check
H1 heading First impression + keyword signal Visible in first viewport
Primary CTA Conversion path Visible and actionable
Hero image/content Visual engagement Loaded, not placeholder
Navigation Usability Accessible (visible or hamburger)
Brand/logo Trust signal Visible, properly sized

Above-Fold Anti-patterns

  • ❌ Full-screen cookie banner obscuring content
  • ❌ Intrusive interstitial (Google penalizes this on mobile)
  • ❌ Auto-playing video with sound
  • ❌ Empty hero area waiting for JS to load
  • ❌ "Loading..." spinners for main content

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.
