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 | $0.00122 | $0.01617 |
| Opus 5 | $0.00061 | $0.00809 |
| Sonnet 5 | $0.00024 | $0.00323 |
| Haiku 4.5 | $0.00012 | $0.00162 |
Grade A, and why
Landing Page Copy 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.
How it starts
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Landing Page Copy
A landing page makes one promise and spends the rest of the page making it believable. The costly mistake this skill prevents is the clever-but-vague page: paid traffic arrives, reads "Supercharge your workflow," and bounces before learning what the product does. Clarity outsells cleverness, and the reader decides in the first five seconds whether to give you thirty more.
Operating procedure
Write top to bottom in the order below, because each section answers the objection the previous one created: the hero makes a claim, proof makes it credible, benefits make it concrete, objections clear the residue, and the CTA collects.
Step 1: Gather inputs
- The one promise - the single outcome the page sells. If the user offers three, make them pick one; the others become body copy. If no positioning exists yet, route to positioning-statement first.
- The ICP and the pain in their own words (support tickets, sales calls, reviews - not the founder's paraphrase). Label paraphrases as guesses.
- The real alternative (spreadsheet, incumbent, doing nothing).
- Available proof: testimonials, logos, numbers, screenshots. Default: if none exists, use specificity of mechanism as interim proof and flag the gap.
- The one action the page asks for (trial, demo, waitlist) and what happens after the click.
- Where traffic comes from - the page must echo the promise of the ad or post that sent them (message match; optimizing this loop afterward is landing-page-cro).
Step 2: Write the hero
- Headline: the core promise in plain language - the outcome, not the feature. Test: a stranger knows what they get within 5 seconds. Under 10 words.
- Subhead: who it's for and how it works, in one sentence.
- CTA button: a verb plus the value ("Start free", "Get the template") - never "Submit" or "Learn more".
- Supporting visual: show the outcome or the product doing the promise, not an abstract illustration.
Bad hero: "Unlock the power of intelligent automation" / "Our AI-driven platform revolutionizes how modern teams work" / [Learn More] - no outcome, no audience, three buzzwords, a CTA that promises homework.
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 Copy is a skill published in the GitHub repository SkillMedev/content-marketing-engine (1 stars, last pushed 2mo ago), licensed MIT. It adds 122 tokens to every session and 1,617 once invoked, about $0.0006 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.
