What you get
- A type-only 16:9 WebP with key words boxed in color and your brand and headline exactly as you wrote them
- The exact prompt it sent plus the saved FAL task file; rerunning resumes that request rather than buying a new one
- A review of spelling, the 6% safe margin and the 16:9 frame before the card reaches you
Good fit
- Identity, security and developer platforms
- Launches carried by one strong sentence
- Talk titles and blog posts with a sharp line
Not for
- Headlines of more than about eight words
- Product screens, photos or charts
- Copying a real company's campaign
About this Skill
When the headline is the whole pitch, this Fable 5 OG image skill builds the card from words alone. The page is pale gray. Your headline runs over several lines in very large black sans-serif, with one or two key words set apart in thin rounded outline boxes and colored bright blue or coral. Faint wavy contour lines trace the sides, and a small wordmark signs the card. The agent picks the words to box, asks GPT Image 2 on FAL for the image and checks each letter before you get the WebP.
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 small wordmark 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
Do I have to use blue and coral?
No. Bring your own accent colors along with the name and headline (a logo too, if it is yours to use), and the boxed-word layout takes them on. The agent still picks which one or two words to box; nothing from another brand's campaign appears.
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.
