Infographic Generator

Adapted from baoyu-infographic for Hermes Agent's tool ecosystem.

Two dimensions: layout (information structure) × style (visual aesthetics). Freely combine any layout with any style.

When to Use

Trigger this skill when the user asks to create an infographic, visual summary, information graphic, or uses terms like "信息图", "可视化", or "高密度信息大图". The user provides content (text, file path, URL, or topic) and optionally specifies layout, style, aspect ratio, or language.

Options

Layout Gallery

Full definitions: references/layouts/<layout>.md

Style Gallery

Full definitions: references/styles/<style>.md

Recommended Combinations

Default: bento-grid + craft-handmade

Keyword Shortcuts

When user input contains these keywords, auto-select the associated layout and offer associated styles as top recommendations in Step 3. Skip content-based layout inference for matched keywords.

If a shortcut has Prompt Notes, append them to the generated prompt (Step 5) as additional style instructions.

Output Structure

infographic/{topic-slug}/
├── source-{slug}.{ext}
├── analysis.md
├── structured-content.md
├── prompts/infographic.md
└── infographic.png

Slug: 2-4 words kebab-case from topic. Conflict: append -YYYYMMDD-HHMMSS.

Core Principles

• Preserve source data faithfully — no summarization or rephrasing (but strip any credentials, API keys, tokens, or secrets before including in outputs)
• Define learning objectives before structuring content
• Structure for visual communication (headlines, labels, visual elements)

Workflow

Step 1: Analyze Content

Load references: Read references/analysis-framework.md from this skill.

1. Save source content (file path or paste → source.md using write_file)
   • Backup rule: If source.md exists, rename to source-backup-YYYYMMDD-HHMMSS.md
2. Analyze: topic, data type, complexity, tone, audience
3. Detect source language and user language
4. Extract design instructions from user input
5. Save analysis to analysis.md
   • Backup rule: If analysis.md exists, rename to analysis-backup-YYYYMMDD-HHMMSS.md

See references/analysis-framework.md for detailed format.

Step 2: Generate Structured Content → structured-content.md

Transform content into infographic structure:

1. Title and learning objectives
2. Sections with: key concept, content (verbatim), visual element, text labels
3. Data points (all statistics/quotes copied exactly)
4. Design instructions from user

Rules: Markdown only. No new information. Preserve data faithfully. Strip any credentials or secrets from output.

See references/structured-content-template.md for detailed format.

Step 3: Recommend Combinations

3.1 Check Keyword Shortcuts first: If user input matches a keyword from the Keyword Shortcuts table, auto-select the associated layout and prioritize associated styles as top recommendations. Skip content-based layout inference.

3.2 Otherwise, recommend 3-5 layout×style combinations based on:

• Data structure → matching layout
• Content tone → matching style
• Audience expectations
• User design instructions

Step 4: Confirm Options

Use the available user-input mechanism only when an unresolved choice materially affects the result. Otherwise proceed with the user's stated choices and reasonable defaults; do not require a tool named clarify:

Q1 — Combination: Present 3+ layout×style combos with rationale. Ask user to pick one.

Q2 — Aspect: Ask for aspect ratio preference (landscape/portrait/square or custom W:H).

Q3 — Language (only if source ≠ user language): Ask which language the text content should use.

Step 5: Generate Prompt → prompts/infographic.md

Backup rule: If prompts/infographic.md exists, rename to prompts/infographic-backup-YYYYMMDD-HHMMSS.md

Load references: Read the selected layout from references/layouts/<layout>.md and style from references/styles/<style>.md.

Combine:

1. Layout definition from references/layouts/<layout>.md
2. Style definition from references/styles/<style>.md
3. Base template from references/base-prompt.md
4. Structured content from Step 2
5. All text in confirmed language

Aspect ratio resolution for {{ASPECT_RATIO}}:

• Named presets → ratio string: landscape→16:9, portrait→9:16, square→1:1
• Custom W:H ratios → use as-is (e.g., 3:4, 4:3, 2.35:1)

Save the assembled prompt to prompts/infographic.md using write_file.

Step 6: Generate Image

Use the installed image-generate skill and its bundled generate-and-deliver helper with the assembled prompt from Step 5; follow its single-delivery contract. Do not assume a tool named image_generate exists.

• Use the image-generate helper's supported sizes: landscape 1792x1024, portrait 1024x1792, square 1024x1024; check model capability.
• For custom ratios, pick the closest named aspect
• On failure, auto-retry once
• Save the resulting image URL/path to the output directory

Step 7: Output Summary

Report: topic, layout, style, aspect, language, output path, files created.

Pitfalls

1. Data integrity is paramount — never summarize, paraphrase, or alter source statistics. "73% increase" must stay "73% increase", not "significant increase".
2. Strip secrets — always scan source content for API keys, tokens, or credentials before including in any output file.
3. One message per section — each infographic section should convey one clear concept. Overloading sections reduces readability.
4. Style consistency — the style definition from the references file must be applied consistently across the entire infographic. Don't mix styles.
5. Output verification — inspect generated text against every source field; OCR is an aid, not proof. Do not invent missing metrics or branding. Use supported image-generate sizes rather than an undocumented tool format.
