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

landing-page-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 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.

Landing Page Optimizer

Audit and optimize landing pages for maximum conversion.

Audit Framework

Above the Fold (First 5 Seconds)

The visitor must answer 3 questions instantly:

  1. What is this? (Clear headline)
  2. Why should I care? (Benefit-focused subheadline)
  3. What do I do next? (Visible CTA)

Hero Layout Patterns

Pattern Best For Structure
Left copy / right visual SaaS, B2B Headline + CTA left, product screenshot right
Centered hero Simple offers Centered headline, subheadline, CTA
Video hero Complex products Autoplay background or embedded explainer
Social proof hero High-trust needed Headline with customer logos or metrics
Split test Dual audiences Two distinct paths with separate CTAs

Value Proposition Hierarchy

H1: Primary benefit (what outcome they get)
Subheadline: How you deliver it (mechanism or differentiator)
Supporting points: 3 proof points or features (bullets)
CTA: Specific action + anxiety reducer

CTA Optimization

Text: Action verb + specific outcome ("Start Free Trial" not "Submit") Design: High contrast to background, generous padding, whitespace around it Placement: Above fold, after each content section, sticky on scroll Microcopy: Reduce anxiety below CTA ("No credit card required", "Cancel anytime")

Social Proof Patterns

Type Placement Impact
Customer logos Below hero Trust (B2B)
Metric ("50,000+ users") Near headline Scale proof
Star rating Near CTA Purchase confidence
Testimonial quote Mid-page Emotional proof
Case study result Deep in page Detailed proof
Trust badges Near form/checkout Security

Form Optimization

  • Every field removed increases completion 5-10%
  • Labels above fields (never placeholder-only)
  • Inline validation (real-time, not on submit)
  • Smart defaults and autofill (autocomplete attributes)
  • Multi-step forms outperform single long forms
  • Progress indicator for multi-step

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.
