Token cost

What it costs to keep this loaded

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.

Security

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 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.

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Landing Page Copy

A first-time founder's landing page usually fails the same way: it talks about the product instead of the customer, lists features instead of outcomes, drowns the visitor in jargon, and asks them to do five things at once. A visitor decides in seconds whether to stay. This skill writes conversion-first copy - leading with the [ICP]'s problem and the outcome they want, one sharp headline, real proof, the top objection handled, and one call to action.

One page, one job. The page exists to move [ICP] to a single next action - not to explain everything [STARTUP_NAME] can do.

The method

Built on the Founder OS scaffold (High tier). Full section template, formulas and examples in references/landing-copy.md.

Step 1 - Lead with the problem and the outcome, not the product

The visitor cares about their problem, not your features. Open by naming [PROBLEM] in the [ICP]'s own words and the outcome they get - the after-state, the win. Features are evidence for the outcome; they are never the lead. Translate every feature into a "so you can…" benefit before it earns a place on the page.

Step 2 - Write the headline + subhead

The headline is the single most important line on the page. It must, in one read, say what this is, who it's for, and the outcome. The subhead earns the next scroll: it adds the how or the for whom the headline left out. Use the headline formulas in the reference, write 5-10 candidates, and pick the clearest - not the cleverest. Clarity beats clever, every time.

Step 3 - Build the body in order: problem → value → how it works → proof

Lay the page out as a logical argument the visitor can follow at a glance:

  • Problem - agitate it just enough that they feel understood.
  • Solution / value - the outcome, with features as supporting evidence.
  • How it works - 3 simple steps so it feels achievable, not magical. Use the section-by-section template in the reference. Each section does one job and hands off to the next.

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.
