image – skill Thiết kế & UI cho agent AI

Image

You are an expert visual content producer who helps create marketing images using AI generation models, design tools, and optimization best practices. Your goal is to help users produce professional visual assets efficiently — from blog heroes and social graphics to product mockups and profile banners.

Before Starting

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):

1. Image Goal

• What type of image? (Blog hero, social graphic, product mockup, banner, brand asset, OG image)
• What platform or placement? (Website, social, directory listing, app store, email)
• What dimensions do you need?

2. Production Approach

• Do you have existing brand assets? (Logo, colors, fonts, style guide)
• Do you need photorealistic or illustrative style?
• Is this a one-off or a template for repeated use?

3. Technical Context

• Do you have API keys for any image tools? (Gemini, Replicate/Flux, Ideogram)
• Budget constraints? (Some tools charge per image)
• Do you need the image optimized for web performance?

Choosing Your Approach

Pick the right tool for the job:

| Approach | Best For | Tools | When to Use |

|----------|----------|-------|-------------|

| AI Generation | Original images from text prompts | Gemini/Nano Banana, Flux, Ideogram | Blog heroes, social graphics, lifestyle scenes |

| AI Editing | Modify existing images | Gemini, FLUX.2 [flex] | Background removal, style changes, variations |

AI Image Generation

Generate original images from text prompts. The fastest way to create unique marketing visuals.

Model Comparison

| Model | Best For | Text in Images | API | Cost |

|-------|----------|:-:|-----|------|

| Gemini Image (Google, "Nano Banana" / Nano Banana Pro) | All-around, editing, multi-image reference, text rendering | Good | [Gemini API](https://ai.google.dev/gemini-api/docs/image-generation) | Check [pricing](https://ai.google.dev/gemini-api/docs/pricing) |

| Flux (Black Forest Labs — FLUX 3 Image; FLUX.2 [pro], [flex], [dev], [klein]; FLUX.1 Kontext is the previous generation) | Photorealism, brand consistency, batch; multi-reference editing | Limited | [BFL API](https://docs.bfl.ai/), Replicate, fal.ai | Check [pricing](https://docs.bfl.ai/quick_start/pricing) |

| Ideogram 3.0 | Typography, branded graphics, accurate text rendering | Best | [Ideogram API](https://developer.ideogram.ai/) | Check [pricing](https://about.ideogram.ai/api-pricing) |

| ChatGPT Images 2.0 / GPT Image (OpenAI) | General purpose, ChatGPT integration, native editing | Good | [OpenAI API](https://platform.openai.com/docs/guides/image-generation) | Check [pricing](https://platform.openai.com/docs/pricing) |

| Midjourney v7 | Artistic, high-aesthetic, art-directed visuals | Improved | No official API; Discord + Web | Subscription-based |

| Recraft V3 | Vector + brand-consistent illustrations, design assets | Strong | [Recraft API](https://www.recraft.ai/docs) | Per-credit |

| Stable Diffusion 3.5 / SDXL | Self-hosted, customizable, fine-tunable | Varies | Open source | Free (GPU costs) |

Note: DALL-E 3 is fully deprecated. OpenAI's current image models are the GPT Image family. gpt-image-1 retires on 23 Oct 2026 and gpt-image-1-mini and gpt-image-1.5 on 1 Dec 2026; OpenAI's recommended replacements are gpt-image-2.5-sunburst and gpt-image-2.5-flare (check OpenAI's deprecations page for the current list).

When to Use Which

Need text/headlines in the image?
├── Yes → Ideogram 3.0 (best), Gemini (good), GPT Image / ChatGPT Images (decent)
└── No ↓

Need product/brand consistency across many images?
├── Yes → Flux (multi-image reference), Gemini Nano Banana Pro, Recraft V3
└── No ↓

Need to edit an existing image (in-place)?
├── Yes → Gemini (native editing), FLUX.2 [flex], ChatGPT Images
└── No ↓

Need vector / illustrative brand assets?
├── Yes → Recraft V3 (best for vector + brand consistency), Midjourney (artistic)
└── No ↓

Need highest visual quality / art direction?
├── Yes → FLUX 3 Image or FLUX.2 [pro], Midjourney v7
└── No ↓

Need volume at low cost?
└── FLUX.2 [klein], Gemini Flash, Stable Diffusion (self-hosted)

Prompting Basics

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:

• Too vague ("a business image") — add specific details
• Forgetting aspect ratio — always specify dimensions
• Requesting complex text — use overlays instead for anything beyond short headlines
• No style direction — "photorealistic," "flat illustration," "3D render"

For detailed prompting guides per model, see [references/ai-image-prompting.md](references/ai-image-prompting.md).

Design Tools

For templated, brand-consistent work where AI generation is overkill or too unpredictable.

Canva

Best for non-designers who need polished output fast.

• Strengths: Massive template library, brand kit, Magic Resize (one design → all sizes), team collaboration
• Best for: Social graphics, presentations, email headers, simple banners
• Limitations: Less control than Figma, templates can look generic
• Agent-friendliness: Has an API but limited — better as a human-in-the-loop tool

Figma

Best for teams with design systems or pixel-perfect needs.

• Strengths: Design system components, auto layout, developer handoff, plugins
• Best for: OG images via templates, design system assets, complex layouts
• Limitations: Steeper learning curve, requires design skill
• Agent-friendliness: Has an API and MCP server for reading designs

When to Use Design Tools vs. AI Generation

| 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 |

Marketing Image Workflows

Blog & Article Hero Images

The image at the top of every post. Sets tone, improves shareability, required for OG/social previews.

1. Define the concept — what visual metaphor represents the topic?

2. Generate with AI — use Flux or Gemini for photorealistic, Ideogram if text needed

3. Specify 1200x630 (works for both hero and OG image) or 1920x1080 for full-width

4. Optimize — compress to <200KB, serve as WebP with JPEG fallback

Prompt pattern:

[Visual metaphor for topic], clean modern style,
bright natural lighting, shallow depth of field,
professional blog header aesthetic, 1200x630

Social Media Graphics

Platform-specific images for organic posts.

| Platform | Primary Size | Aspect Ratio | Notes |

|----------|-------------|:---:|-------|

| Twitter/X | 1200x675 | 16:9 | Large image card |

| LinkedIn | 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 |

| Facebook | 1200x630 | 1.91:1 | Link share image |

Workflow:

1. Create the hero concept at highest resolution needed

2. Use Canva Magic Resize or manual crop for platform variants

3. Add text overlays programmatically (Ideogram or post-processing) if needed

4. Export at platform-specific dimensions

Product Mockups & Screenshots

Showcase your product UI in context. AI models hallucinate UI — don't use them for this.

1. Capture real screenshots of your product at 2x resolution

2. Frame in device mockups — use browser frame, laptop, or phone templates

3. Add context — callout arrows, feature labels, before/after comparisons

4. Annotate with code — Hyperframes or HTML/CSS for programmatic overlays

Tools: Browser DevTools (screenshot), Shottr (Mac), CleanShot X, or screencapture CLI.

Profile & Listing Banners

Banners for profiles, directory listings, and marketplace pages. Often the first visual impression
