Image Prompt Writer

Craft optimized prompts for tacosdedatos illustrations using the 7 defined style modes.

Required reference: Read agents/shared/illustration-style-guide.md first for color palette, mode templates, and negative prompts.

The Process

Step 1: Understand the Content

Gather these inputs:

  • Post title: What's the article called?
  • Summary: 1-2 sentence description of the content
  • Tone: Technical, reflective, playful, personal?
  • Key concept: What's the ONE main idea to visualize?

Step 2: Select the Mode

Match content type to illustration mode:

| Content Type | Recommended Mode | |--------------|------------------| | Technical tutorial, system architecture | Abstract/Geometric | | Evolution, before/after, layered concepts | Paper-Cut/Layered | | Reflective, philosophical, time/change | Surrealist/Evocative | | Growth narratives, learning journeys | Nature + Tech Fusion | | Personal stories, "lo que ando haciendo" | Atmospheric/Cinematic | | How-tos, team content, energetic pieces | Playful Cartoon | | Data analysis, analytics, visualization | Data Dashboard |

Step 3: Identify the Visual Metaphor

The illustration should represent the concept visually, not literally.

Good metaphors (from published examples):

  • AI processing → geometric shapes flowing into brain network
  • Time/timestamps → melting clock with butterflies
  • Building something → puzzle pieces forming a path
  • Data cultivation → garden with floating data cards
  • Orchestrating AI → conductor's baton with flowing lines

Bad approaches:

  • Generic person at laptop
  • Literal representation of the topic
  • Stock illustration style

Step 4: Build the Prompt

Use the template for your selected mode from illustration-style-guide.md.

Template structure:

[Style specification]
[Background color]
[Subject/metaphor description]
[Color specifications with hex codes]
[Composition notes]
[Texture/style notes]
[Negative constraints]

Step 5: Add Negative Prompts

Always append these exclusions:

Universal (always include):

no text, no words, no labels, no watermarks, no signatures, no logos

Style protection:

no photorealism, no 3D render, no harsh gradients, no glossy surfaces
no stock illustration style, no corporate clip art

Quality:

no blur, no artifacts, no low resolution

Output Format

When delivering a prompt, provide:

## Generated Prompt

**Mode**: [Selected mode]
**Rationale**: [Why this mode fits the content]

### Prompt
[Complete prompt text]

### Negative Prompt
[All negative constraints]

### Generation Settings
- Aspect ratio: 16:9 or 3:2 (landscape)
- Resolution: 2K recommended

Examples

Example 1: Technical Post

Input: "Subagentes de Claude Code: Primeras impresiones del día cero"

Output:

  • Mode: Abstract/Geometric
  • Metaphor: Terminal window branching into multiple output streams
Flat digital illustration on very dark background (#121212).
A stylized terminal window on the left, with three colored lines (red, teal, cream) branching out to the right into separate output streams with icons.
Colors: Crema Nevada (#F1FAEE) for the terminal outline, Rojo Fuego (#E63946), Azul Niebla (#A8DADC), and Naranja Cempasúchil (#F4A261) for the branching lines.
Style: clean geometric, subtle grain texture, generous negative space, minimal elements.
No text, no words, no labels, no photorealism, no 3D render, no gradients.

Example 2: Personal Reflection

Input: "Desde el precipicio" - reflective piece about a turning point

Output:

  • Mode: Surrealist/Evocative
  • Metaphor: Melting clock representing time at a crossroads
Surrealist digital illustration, dreamlike atmosphere.
A melting clock (Dalí-style) as the central element, with butterflies and small birds emerging from its dripping form.
Dark background (#121212) with Naranja Cempasúchil (#F4A261) and Azul Niebla (#A8DADC) for the butterflies.
Crema Nevada (#F1FAEE) for the clock face.
Style: flowing organic forms, emotional resonance, subtle grainy texture.
No text, no photorealism, no harsh edges.

Troubleshooting Prompts

| Issue | Solution | |-------|----------| | Image too literal | Focus on metaphor, not direct representation | | Wrong colors | Include hex codes explicitly in prompt | | Too cluttered | Reduce elements, emphasize "generous negative space" | | Generic style | Add "subtle grain texture" and specific style terms | | Text appearing | Add "no text, no words, no labels" to negatives |
