Version history
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Gather this context (ask if not provided):

A strong image prompt follows: Subject + Setting + Style + Lighting + Composition + Technical
A laptop on a minimal white desk showing a dashboard UI,
soft directional lighting from the left, shallow depth of field,
clean commercial photography style, 16:9 aspect ratio, 4K
Common mistakes:
For detailed prompting guides per model, see references/ai-image-prompting.md.
For templated, brand-consistent work where AI generation is overkill or too unpredictable.
Best for non-designers who need polished output fast.
Best for teams with design systems or pixel-perfect needs.
| Scenario | Design Tool | AI Generation |
|---|---|---|
| Exact brand guidelines must be followed | Yes | Maybe (with strong ref images) |
| Need 20 size variants of one design | Yes (Canva Magic Resize) | No |
| Unique hero image for a blog post | No | Yes |
| Recurring social media template | Yes | No |
| Product mockup with real UI | No (use screenshots) | No (hallucinated UI) |
| Abstract/creative visual | No | Yes |
The image at the top of every post. Sets tone, improves shareability, required for OG/social previews.
Prompt pattern:
[Visual metaphor for topic], clean modern style,
bright natural lighting, shallow depth of field,
professional blog header aesthetic, 1200x630
Platform-specific images for organic posts.
| Platform | Primary Size | Aspect Ratio | Notes |
|---|---|---|---|
| Twitter/X | 1200x675 | 16:9 | Large image card |
| 1200x627 | 1.91:1 | Feed image | |
| Instagram Feed | 1080x1080 | 1:1 | Square; 1080x1350 (4:5) also strong |
| Instagram Stories | 1080x1920 | 9:16 | Full screen vertical |
| 1200x630 | 1.91:1 | Link share image |
Workflow:
Showcase your product UI in context. AI models hallucinate UI — don't use them for this.
Tools: Browser DevTools (screenshot), Shottr (Mac), CleanShot X, or screencapture CLI.
Banners for profiles, directory listings, and marketplace pages. Often the first visual impression.
| Platform | Size | Notes |
|---|---|---|
| LinkedIn personal cover | 1584x396 | 4:1, safe zone center |

Best practices:
Workflow:
Logos, icons, and illustrations. AI generation has limits here.
| Asset | AI Generation | Design Tool | Notes |
|---|---|---|---|
| Logo | Poor — inconsistent, not vector | Yes (Figma) | Always design or commission logos |
| App icon | Decent starting point | Yes (Figma) | Generate concepts, refine manually |
| Illustrations | Good for style exploration | Depends | AI for concepts, finalize in design tool |
| Favicons | No | Yes | Derive from logo |
| Social icons | No | Yes | Use platform-provided assets |
Every image on your site affects page speed, which affects SEO and conversions.
