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 | $0.00046 | $0.01330 |
| Opus 5 | $0.00023 | $0.00665 |
| Sonnet 5 | $0.00009 | $0.00266 |
| Haiku 4.5 | $0.00005 | $0.00133 |
Grade A, and why
landing-page 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 4d 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.
This is a copy
100% identical to landing-page — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Landing Page (High‑Conversion) — Web Design Skill
A landing page is not a homepage. A homepage serves multiple intents. A landing page wins one intent: one offer → one audience → one primary action.
Before you design/write
Gather (ask if missing):
1) Page purpose
- What is the ONE primary action? (trial, demo, buy, waitlist, download)
- What’s the offer? (exactly what do they get?)
- What counts as conversion? (click, signup, purchase)
2) Audience + context
- Who is the ICP?
- What problem are they trying to solve?
- Top 3 objections (why they don’t convert today)
- Traffic source: ads / search / social / email
- What do visitors already know when they land?
3) Proof + assets
- Any proof points: logos, testimonials, numbers, case studies
- Screenshots, demo video, product GIFs
- Guarantees / refund / cancellation terms
4) Constraints
- Brand voice: casual vs professional
- Design direction: minimal editorial vs playful 3D vs glass UI
- Mobile priority?
Core structure (what it should include)
Above the fold (must)
- Headline (outcome + audience)
- Subheadline (clarifies “how” + adds specificity)
- Primary CTA (clear verb + what they get)
- One proof signal (logo strip / stat / short testimonial)
- Hero visual (product screenshot/video) or a strong illustration
Mid page (argument)
- Problem → solution (1 section)
- Benefits (3–5, outcome-driven)
- How it works (3 steps)
- Social proof (testimonials/case study)
Bottom (objection handling)
- FAQ (6–12 Q/A)
- Risk reversal (trial, cancel anytime, guarantee)
- Final CTA (same as top)
Layout types (pick one)
A) Classic hero + sections (most common)
Best when:
- product is understandable with a hero screenshot
B) Long-form story (sales page)
Best when:
- you need to educate + overcome skepticism
C) Minimal conversion page
Best when:
- high-intent traffic (email → known users)
- short offer (download, waitlist)
What ships with it
4 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.
