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 | $0.00024 | $0.00448 |
| Opus 5 | $0.00012 | $0.00224 |
| Sonnet 5 | $0.00005 | $0.00090 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
landing-page-design 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 yesterday.
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.
What it actually says
Landing page design (Elaya)
MIT. Upstream URLs in SOURCE.md. Palette ban: premium-ui-craft. Tokens below are marketing defaults, not mandates; existing system/brand wins.
Product / in-app: no island nav, 700ms springs, Phosphor-only, or no-serif. Use premium-ui-craft. Keep copy rules (no lorem, no Elevate/Seamless, real CTAs, full states).
Strategy
One offer → one audience → one primary action. Hero, benefits, how it works, proof, FAQ, final CTA. No competing CTAs above the fold. Real names and numbers or omit them.
Visual (marketing defaults)
- Fonts: default Geist, Manrope, Geist Mono, Poppins; brand fonts win. No italics. No 900. One typeface. Tailwind scale only.
- Spacing: 0, 2, 4, 8, 12, 16, 24, 32, 40, 48, 64, 80, 96px. Nested radius: inner = outer − gap when gap < 32 and result > 2.
- Dark (default):
#000000#181818#1F1F1F#272727#313131#131209. No background gradients. Hero heading may gradient white→gray. - Icons (default): Phosphor, Solar, Iconamoon. Motion (default):
duration-700 ease-[cubic-bezier(0.32,0.72,0,1)]. Scroll via IntersectionObserver.prefers-reduced-motionzeros duration (required). - States: hover, active, focus, loading, empty, error. Keyboard + contrast per
premium-ui-craftbaseline. No#dead links. No lorem, Acme, fake %, AI cliches.

What ships with it
1 file 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.

landing-page-design is a skill published in the GitHub repository kleosr/kleosrules (2 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 448 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
