About this Skill

Money apps that want energy over polish can hand this layout to their Fable 5 agent. The ground is pure black. A big, wide white headline stacks down the left side; on the right a phone leans steeply into perspective, and thin white lines burst outward from the middle past a few speckled cubes, steps and columns picked out in one bright accent color. The app on that phone is designed fresh for your product, GPT Image 2 on FAL renders the card, and the lettering is checked before the WebP is handed over.
How it works
- Agree on the name, one headline and one picture idea; drop anything that blurs at thumbnail size
- Lay out the card from references/visual-system.md and fit your colors to its four style anchors
- Strip out outside names, marks, faces, screens and slogans, then invent the app screen on the phone for your brand
- Write a prompt about visible things only: frame, layout, light, palette, subject and type position
- Send one request with the bundled FAL helper and keep the task file it writes
- Read each letter, check the 6% margins and the 16:9 frame, and only then run validate-output.mjs
- If a flaw remains, propose one prompt change and wait for your OK before a second paid request
Checked before delivery
- validate-output.mjs passes with --require-format webp --require-16-9, and the prompt file has no emoji, arrows or symbol characters
- Brand and headline read correctly letter by letter, with key text and faces inside a 6% margin on every side
- Every source name, logo, slogan, person, interface and watermark is replaced by the user's own identity or a new one, and the layout is new for this subject
- Exactly one paid request per approved generation

FAQ
Will the phone show a real app?
No, the agent designs a new screen for your product. Share the name, headline and accent color (and a logo or images, if they are yours to use), and the black poster is rebuilt without anything from another brand's app or campaign.
Can it work from an image I already have?
If the image is yours or you may use it, yes. Hand it over with --reference and GPT Image 2 runs in edit mode instead. Only mood, color and layout are taken from the picture; nothing in it is reproduced on the card.
Is there a cost beyond the Skill?
Yes: FAL bills every image to your own account. The helper never retries by itself, and running the same command again only picks up the saved request, so checking on a slow job never pays for a second one.
