Article Thumbnails

Article Thumbnails (article-thumbnails)

Generates and evaluates brand-appropriate thumbnail candidates for articles or newsletters using Gemini models.

Prerequisites

• Requires GEMINI_API_KEY to be set in the environment.

Step-by-Step Instructions

1. Analyze Article Copy

• Read the article text or link provided by the user.
• Identify the core theme, key concepts, tone (e.g. technical, casual, minimal), and metaphoric visual ideas.

2. Suggest Visual Concepts

Propose 3 distinct visual compositions based on the article's theme and your brand guidelines.

• Concept 1 (Conceptual): Abstract representation of the core idea.
• Concept 2 (Literal/Concrete): Showing a practical scenario or object.
• Concept 3 (Minimalist/Graphic): Strong typography and simple icons/shapes.

3. Generate Image Candidates

Ask the user to select their preferred concept. Once selected:

• Construct a detailed image generation prompt following Gemini best practices (specifying subject, style, lighting, composition, and color palette).
• Call your Gemini image generation script or tool with the prompt:

  python3 scripts/call_gemini_image.py --prompt "{detailed_prompt}" --candidates 3
  

• Save the resulting images in a local assets/ folder.

4. Evaluate and Select

• Use your Vision capabilities to inspect the generated candidate images.
• Review each candidate against your brand specifications (correct logo colors, text alignment, and aesthetic appeal).
• Present the best candidates to the user with a brief rationale for each.
