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 | $0.00100 | $0.04280 |
| Opus 5 | $0.00050 | $0.02140 |
| Sonnet 5 | $0.00020 | $0.00856 |
| Haiku 4.5 | $0.00010 | $0.00428 |
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 12d 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
Optimize landing pages for maximum conversions using proven frameworks from Unbounce and Oli Gardner—apply the "one goal, one message, one action" principle with data-driven design, copy, and CTA best practices.
When to Use This Skill
Use this skill when you need to:
- Create a new landing page for a campaign
- Optimize an existing landing page that isn't converting
- Review landing page design before launch
- Improve form conversion rates on lead gen pages
- A/B test landing page elements systematically
- Audit landing pages against best practices
- Write landing page copy that converts
- Design CTAs that drive action
This skill is particularly valuable for:
- PPC marketers running paid campaigns
- Growth marketers optimizing conversion funnels
- Demand gen teams building lead capture pages
- E-commerce marketers creating product landing pages

Methodology Foundation

- Unbounce - "101 Landing Page Optimization Tips" by Oli Gardner
- Unbounce Landing Page Best Practices
- Unbounce Conversion Benchmark Report (57+ million conversions)
Core Principle: One goal, one message, one action. Every element on your landing page should support a single conversion objective with zero distractions.
"Landing page optimization is the process of systematically improving individual elements to increase conversions. It involves making data-driven changes to design, copy, forms, and calls-to-action that guide more visitors toward taking your desired action."

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.
