Kortix image recipe

Turn a visual request into one clean, brand-safe image.

Load kortix-brand first. It owns the values, the voice, the claims and the logo rules. This file owns the procedure only. If a request conflicts with the kit, say so and offer the closest on-brand option.

Output PNG by default. Output SVG only when the user asks for SVG.

Read before you start

NeedRead
Direction, avoid list, reject list, share-card templateart-direction.md

Color and the one-accent rulecolor.md
Words in or beside the image (headline, caption, in-image text)voice-and-tone.md, claims.md, positioning.md

Settle the context below. Default from the kit and the request. Ask only what changes the art direction.

  • Image goal. Type (blog hero, social graphic, product mockup, banner, brand asset, OG image), placement (website, social, directory, app store, email) and dimensions.
  • Production approach. Existing brand assets to use, photoreal or illustrative, one-off or reusable template.
  • Technical. Available image tools and keys (Gemini, Replicate or Flux, Ideogram), budget, and whether the image needs web optimization.

Specs

Generate at the native size of the surface. Keep critical content crop-safe.

  • OG and blog hero: 1200 by 630 (1.91:1)
  • X post: 1200 by 675 (16:9). X header: 1500 by 500
  • LinkedIn post: 1200 by 627. LinkedIn personal cover: 1584 by 396
  • Square (Instagram, launch card): 1080 by 1080. Story or reel: 1080 by 1920 (9:16)

Pin the aspect ratio in the prompt. A forgotten ratio is the most common cause of unusable output.

Tools

  • General generation. Gemini or Flux.
  • A consistent set. Flux multi-reference.
  • Text that must live in the image. Ideogram renders text best. Prefer the default: composite real text in Roobert after generation.
  • Product UI. Never generate it. Screenshot the real Kortix UI at 2x and frame it.

Workflow

  1. Confirm the surface, the aspect ratio and any required text or facts.
  2. Write one short prompt: subject, Kortix product truth, direction from art-direction.md, composition, aspect ratio. Keep it tight. Over-specifying produces worse images.
  3. Generate as PNG. Composite the official logo file and any exact text after. Follow brandmark.md.
  4. For the web, also export an optimized WebP (about 80% quality). Set explicit width and height to avoid layout shift. Add descriptive alt text.
  5. Reject, and do not ship, any image that matches the reject list in art-direction.md.
  6. Report the files you read and a "Guesses" list, as SKILL.md of kortix-brand says.
