About this Skill

If your Fable 5 agent is making the cover for a keyboard tool or power-user app, this is the after-dark option. Deep plum glows red and violet behind a launcher window of frosted, see-through glass, and a huge two-line headline crosses the card: the first word slanted and filled pink to purple, the rest solid white. The window and any keyboard details are invented for you. GPT Image 2 on FAL renders the 16:9 WebP, and every letter is verified first.
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 launcher window and any keys 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 window look like an existing app?
No. The window, its rows and any keyboard details are invented for your product, and outside screens and marks are stripped out. The headline, your name, your colors and a logo you may use make up the identity.
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.
