# Imagegen

## When to use

- Generate brand, website or mobile design images from a visual brief.

**Not for:** frontend-design or image-to-code for implementation.

## Steps

1. Confirm subject, audience, intended use and constraints; load only the relevant brand, web or mobile guidance.

2. Inspect references and mature marks; use deliberate geometry, negative space and restrained palettes when the brief calls for them.

3. Use an available image generation tool; preserve requested transparency and reference identity, and produce only necessary deliverables.

4. Inspect composition, consistency and legibility, show results and obtain feedback before downstream implementation.

## Verify

- Assets match the brief and are inspectable; marks are evaluated at small sizes and in monochrome.
