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 | $0.00060 | $0.01081 |
| Opus 5 | $0.00030 | $0.00541 |
| Sonnet 5 | $0.00012 | $0.00216 |
| Haiku 4.5 | $0.00006 | $0.00108 |
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 9d 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Audit Framework
Above the Fold (First 5 Seconds)
The visitor must answer 3 questions instantly:
- What is this? (Clear headline)
- Why should I care? (Benefit-focused subheadline)
- 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 ships with it
3 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.
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.
