Workflow

Step 1: Analyze Content

Extract key information:

• Main topic: What is the article about?
• Core message: What's the key takeaway?
• Tone: Serious, playful, inspiring, educational?
• Keywords: Identify style-signaling words

Step 2: Select Style

If --style specified, use that style. Otherwise:

1. Scan content for style signals (see Auto Style Selection table)
2. Match signals to most appropriate style
3. Default to elegant if no clear signals

Step 3: Generate Cover Concept

Create a cover image concept based on selected style:

Title (if included, max 8 characters):

• Distill the core message into a punchy headline
• Use hooks: numbers, questions, contrasts, pain points
• Skip if --no-title flag is used

Visual Elements:

• Style-appropriate imagery and icons
• 1-2 symbolic elements representing the topic
• Metaphors or analogies that fit the style

Step 4: Create Prompt File

Prompt Format:

Cover theme: [topic in 2-3 words]
Style: [selected style name]

[If title included:]
Title text: [8 characters or less, in content language]
Subtitle: [optional, in content language]

Visual composition:
- Main visual: [description matching style]
- Layout: [positioning based on title inclusion]
- Decorative elements: [style-appropriate elements]

Color scheme:
- Primary: [style primary color]
- Background: [style background color]
- Accent: [style accent color]

Style notes: [specific style characteristics to emphasize]

[If no title:]
Note: No title text, pure visual illustration only.

Step 5: Generate Image

• Visual metaphors work better than literal representations
• Maintain style consistency throughout the cover
• Image generation typically takes 10-30 seconds
• Title text language should match content language
