# Infographic Generator

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

## Usage

```bash
/canghe-infographic path/to/content.md
/canghe-infographic path/to/content.md --layout hierarchical-layers --style technical-schematic
/canghe-infographic path/to/content.md --aspect portrait --lang zh
/canghe-infographic  # then paste content
```

## 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 all source data **verbatim**—no summarization or rephrasing
- Define learning objectives before structuring content
- Structure for visual communication (headlines, labels, visual elements)

## Workflow

### Step 1: Setup & Analyze

**1.1 Load Preferences (EXTEND.md)**

Use Bash to check EXTEND.md existence (priority order):

```bash
# Check project-level first
test -f .canghe-skills/canghe-infographic/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.canghe-skills/canghe-infographic/EXTEND.md" && echo "user"
```

┌────────────────────────────────────────────────────┬───────────────────┐
│                        Path                        │     Location      │
├────────────────────────────────────────────────────┼───────────────────┤
│ .canghe-skills/canghe-infographic/EXTEND.md          │ Project directory │
├────────────────────────────────────────────────────┼───────────────────┤
│ $HOME/.canghe-skills/canghe-infographic/EXTEND.md    │ User home         │

┌───────────┬───────────────────────────────────────────────────────────────────────────┐
│  Result   │                                  Action                                   │
├───────────┼───────────────────────────────────────────────────────────────────────────┤
│ Found     │ Read, parse, display summary                                              │

└───────────┴───────────────────────────────────────────────────────────────────────────┘

**EXTEND.md Supports**: Preferred layout/style | Default aspect ratio | Custom style definitions | Language preference

Schema: `references/config/preferences-schema.md`

**1.2 Analyze Content → `analysis.md`**

1. Save source content (file path or paste → `source.md`)
   - **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
   - **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. All data verbatim.

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

### Step 3: Recommend Combinations

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 **single AskUserQuestion call** with multiple questions to confirm all options together:

| Question | When | Options |
|----------|------|---------|
| **Combination** | Always | 3+ layout×style combos with rationale |
| **Aspect** | Always | landscape (16:9), portrait (9:16), square (1:1) |
| **Language** | Only if source ≠ user language | Language for text content |

**Important**: Do NOT split into separate AskUserQuestion calls. Combine all applicable questions into one call.

### Step 5: Generate Prompt → `prompts/infographic.md`

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

### Step 6: Generate Image

1. Select available image generation skill (ask user if multiple)
2. **Check for existing file**: Before generating, check if `infographic.png` exists
   - If exists: Rename to `infographic-backup-YYYYMMDD-HHMMSS.png`
3. Call with prompt file and output path
4. On failure, auto-retry once

### Step 7: Output Summary

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