About, method, and disclosure
SpawnPrompt is a library of prompts for people who build software by talking to an agent, and a tool table whose prices can be cited.
Who it is for
People into AI, agents, games, and vibe coding. The gap is Brazilian Portuguese. English is not a footer translation: every prompt and every page has its own URL.
What a prompt here is
Text you paste, with variables in brackets. The page says when to use it, the level, a suggested tool, and where it usually breaks. The tool’s affiliate field exists and is empty. Today’s link is the official site.
Testing method
No prompt in this version was run end to end in an agent. The metadata is “not yet tested”, with no model name and no fake date. The screenshot slot stays empty until someone publishes a real result: tool, model, date, and what came out. A future test has to rerun the prompt with the variables filled in, keep the diff or the generated app, and only then change the status.
Pricing method
Every number comes from an official page, with a URL and a date (2026-10-28 in this version). If the page did not publish the amount, or only published a promo without a stable monthly rate, the price cell says “to be confirmed” and the fetched detail stays in the limits text. A “from” tier is not rounded into a single price. BRL uses one config value: BRL = USD × 5.342 (PTAX sell, 2026-10-28, Banco Central) × (1 + 0.035). That is about 5.5290 reais per dollar. The 3.5% IOF is what Mercado Pago’s open-data page states for credit cards (their update on 2026-10-27). The decree on Planalto blocked the automated fetch, so the rate was not read from the statute. The formula does not include the card issuer’s spread.
Affiliate disclosure
SpawnPrompt may use affiliate links later. In this version every affiliate_url is empty, and no link on the site is sponsored. If a link becomes an affiliate link, it gets rel="sponsored" and this page remains the disclosure: we may earn a commission if you subscribe through that link, at no extra cost the tool declares. That does not change the published price, which stays tied to the source and the date.
