name: sumi description: Generate artistic infographics from any topic. Runs the Sumi pipeline (analyze → structure → craft prompt → generate image) entirely within Claude Code. Use when "generate infographic", "create infographic", "sumi", "make an infographic about", or "visualize topic".

Sumi — Artistic Infographic Generator

Generate a beautiful infographic from a text topic. Claude does all the thinking (analysis, structuring, prompt crafting) using curated reference files. Only the final image generation calls an external API (Gemini).

Usage

The user provides:

• topic (required): The subject or pasted text to turn into an infographic
• style (optional): A style ID like ukiyo-e, bauhaus, sumi-e, etc.
• layout (optional): A layout ID like bento-grid, hub-spoke, iceberg, etc.
• aspect_ratio (optional): e.g. 16:9, 9:16, 1:1. Default: 16:9

If style or layout are not specified, recommend 3 combinations and let the user pick.

Reference Files

All reference files live in this skill's references/ directory:

• references/analysis-framework.md — Framework for analyzing content
• references/structured-content-template.md — Template for structuring content
• references/base-prompt.md — Base prompt template for image generation
• references/styles/{style-id}.md — Style definitions (60+ styles)
• references/layouts/{layout-id}.md — Layout definitions (20 layouts)

IMPORTANT: Read the relevant reference files before each step. These contain the secret sauce — detailed visual instructions, color palettes, compositional patterns, and visual metaphor mappings that make the infographics excellent.

Instructions

Step 1: If style/layout not specified, recommend combinations

1. Read references/analysis-framework.md
2. Analyze the user's topic using the framework (just do the analysis yourself — you ARE Claude)
3. Based on the content type, complexity, and audience, recommend 3 layout×style combinations:
   • best_match — most appropriate for the content
   • creative — unexpected, visually striking pairing
   • accessible — broadest appeal, balances clarity and aesthetics
4. For each recommendation, give a 1-2 sentence rationale
5. Ask the user to pick (1/2/3 or name their own)

To make good recommendations, consult the analysis framework's Content Type Classification table which maps content types to layouts and styles.

Step 2: Analyze content

Read references/analysis-framework.md and apply it to the topic. Produce a thorough analysis covering:

• Content type classification (timeline, process, comparison, hierarchy, etc.)
• Learning objectives (what the viewer will understand)
• Audience analysis
• Complexity assessment
• Visual opportunity mapping
• Data verbatim extraction (preserve all statistics, quotes, dates EXACTLY)

This analysis is internal working material — don't dump it on the user. Just mention you're analyzing.

Step 3: Structure content

Read references/structured-content-template.md and transform the analysis into designer-ready structured content:

• Title and overview
• Sections with key concepts, content points, visual elements, and text labels
• All data points preserved verbatim
• Clear visual element descriptions per section

Step 4: Craft the image generation prompt

This is where it all comes together. Read:

• references/layouts/{selected-layout-id}.md — the full layout definition
• references/styles/{selected-style-id}.md — the full style definition
• references/base-prompt.md — the base prompt template

Then craft a rich, detailed image generation prompt with these sections:

Fixed header (one line):

Create a single {aspect_ratio} infographic in {Style Name} style using a {Layout Name} layout. All text in English. Use rich visual scenes with clear hierarchy and ample whitespace.

Layout Guidelines: Adapt the generic layout structure to this specific content. Replace placeholders with content-specific descriptions.

Style Guidelines: Include the FULL style description plus:

• Color Palette with specific usage instructions
• Visual Elements list
• A Compositional Patterns table mapping content structures to style-specific compositions
• Visual Metaphor Mappings that translate EACH content section into a concrete, style-specific visual scene
• Typography instructions

Content: Describe each content section as a VISUAL SCENE. Each section must have:

• A descriptive title (e.g., "CENTER HUB: The Castle")
• A vivid description of what to DRAW — objects, characters, spatial layout, colors, mood
• The exact text to render

Text Labels: Organize ALL text that should appear in the infographic, grouped by area: Title, Hub/Center, Section Labels, Section Content, Key Phrases, Attribution.

CRITICAL PROMPT CRAFTING RULES

• Describe VISUAL SCENES, not abstract concepts. Tell the image generator what to DRAW.
• Visual metaphor mappings must be SPECIFIC to the content AND style (e.g., for ukiyo-e: "Trust Signals → guardian komainu statues or a samurai standing watch")
• Keep all source quotes and data VERBATIM — never summarize or rephrase
• The prompt should be 1500-3000 words — rich enough for Gemini to produce a detailed infographic

Save the crafted prompt to a file for reference.

Step 5: Generate the image

The ONLY step that needs an external API call. Use the Sumi backend's image generator:

cd /Users/paolo/playground/sumi/backend && source .venv/bin/activate && python -c "
import asyncio
from sumi.engine.image_generator import generate_image

PROMPT = open('/tmp/sumi-prompt.md').read()
ASPECT_RATIO = 'ASPECT_RATIO_HERE'
OUTPUT_PATH = '/tmp/sumi-infographic.png'

async def main():
    path = await generate_image(prompt=PROMPT, output_path=OUTPUT_PATH, aspect_ratio=ASPECT_RATIO)
    print(f'Image saved: {path}')

asyncio.run(main())
"

Before running this:

1. Write the crafted prompt to /tmp/sumi-prompt.md
2. After generation, open the image with open <path> on macOS
3. Tell the user the file path

Step 6: Iterate (if requested)

If the user wants to tweak:

• Different style/layout: Re-do steps 4-5 with new references (skip analysis/structuring)
• Prompt adjustments: Edit the saved prompt and re-run step 5
• Content changes: Re-do from step 2
