**GPT-Image2 enforces infographic module count through explicit template guidelines, a typed JSON schema with a bounded `modules` array, and front-end rendering logic that iterates only over supplied modules.**

The **freestylefly/awesome-gpt-image-2** repository treats every visual prompt as a structured template that agents invoke programmatically. For infographic prompts, **module-count control** prevents visual overload by bounding the number of visual blocks. This article breaks down the three-layer enforcement system implemented in the codebase.

## Explicit Documentation: The "Control Module Count" Rule

The foundation of module-count governance lives in [`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md). The **"避坑指南"** (pitfall avoidance) section mandates that authors state a concrete number of modules upfront.

In [`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md) at line 144, the documentation explicitly warns against unbounded layouts. By forcing authors to declare a fixed module count, the template prevents the LLM from generating chaotic, overstuffed infographics. This human-readable rule sits at the top of the enforcement chain.

## JSON Schema: The `modules` Array as Programmatic Control Point

The same file provides a machine-readable **JSON representation** of infographic templates. The schema centers on a `structure` object containing a `modules` array—this array's length is the definitive control point.

```json
{
  "type": "Infographic",
  "topic": "Urban Metabolism",
  "audience": "General Public",
  "structure": {
    "title_area": "城市生命系统图谱",
    "layout": "Isometric cutaway, 3 numbered panels",
    "modules": [
      { "title": "能源", "icon": "lightning", "text": "Power flows" },
      { "title": "水循环", "icon": "water_drop", "text": "Water flows" },
      { "title": "废料", "icon": "recycle", "text": "Waste loops" }
    ]
  },
  "style": {
    "aesthetic": "Scientific atlas",
    "colors": "Low saturation, color-coded flows",
    "background": "Light paper texture"
  },
  "constraints": "No cyberpunk, no gibberish text, strict structural layout"
}

```

The `modules` array above contains exactly three entries. Developers and agents set this length intentionally to satisfy the "控制模块数量" guideline. Because the schema is typed and validated, malformed or oversized arrays fail at the template ingestion stage.

## Front-End Rendering: React Iterates Only Over Supplied Modules

The final enforcement layer lives in [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx). The front-end reads `styleLibrary.templates` and renders each module entry without transformation or truncation.

At lines 2645-2649, the rendering logic maps directly over the `modules` array:

```jsx
{/* inside src/main.jsx */}
{templates
  .filter(t => t.category === 'infographic')
  .map(item => (
    <article className="caseCard templateVisualCard" key={item.id}>
      <h3>{item.title}</h3>
      {/* Render each module – the count is dictated by the JSON payload */}
      {item.structure.modules.map((mod, i) => (
        <div className="infographicModule" key={i}>
          <h4>{mod.title}</h4>
          <p>{mod.text}</p>
        </div>
      ))}
    </article>
  ))}

```

**Critical behavior**: The UI does not pad, clip, or paginate modules. If `item.structure.modules` contains three elements, three panels render. If it contains eight, eight render. This passthrough design makes the JSON array length the single source of truth for infographic density.

## Where Module Count Is Defined and Enforced

| File | Role in Module Count Control |
|------|------------------------------|
| [`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md) | Human guideline: "控制模块数量" rule at line 144 |
| [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) | Rendering engine: iterates `structure.modules` at lines 2645-2649 |
| [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) | Data store: holds template objects with bounded `modules` arrays |
| [`agents/skills/gpt-image-2-style-library/references/style-library.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/agents/skills/gpt-image-2-style-library/references/style-library.md) | Agent guidance: additional references on limiting module count at line 67 |

## Practical Implementation for Agents

When building agent-level prompts that invoke GPT-Image2, construct the template JSON with an explicit module count in mind. The **style-library** reference at line 67 reinforces this practice for programmatic use cases.

Agents should:
- Validate `modules.length` against a maximum threshold (commonly 3-5 for readability)
- Reject or split templates exceeding the threshold
- Include the module count in metadata for downstream transparency

## Summary

- **Documentation layer**: The [`templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/templates.md) "避坑指南" establishes the module-count rule as a mandatory authoring guideline.
- **Schema layer**: The JSON `structure.modules` array length acts as the typed, programmatic control point.
- **Rendering layer**: [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) iterates faithfully over supplied modules, making array length determinative of visual output.

GPT-Image2's three-tier system ensures infographic module count remains intentional, bounded, and reproducible across human and agent workflows.

## Frequently Asked Questions

### How does GPT-Image2 prevent infographic visual overload?

The repository implements a **template-based constraint system**. Authors must declare a fixed module count in the template's `structure.modules` array. The front-end renders exactly those modules with no expansion or truncation, capping visual density at the source.

### Can I dynamically adjust module count at runtime?

No. The [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) rendering logic at lines 2645-2649 performs a direct map over `item.structure.modules` without conditional slicing or pagination. Adjusting module count requires regenerating or selecting a different template JSON with the desired array length.

### Where is the module count limit documented for template authors?

The primary documentation lives in [`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md) at line 144 within the "避坑指南" section. Additional agent-focused guidance appears in [`agents/skills/gpt-image-2-style-library/references/style-library.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/agents/skills/gpt-image-2-style-library/references/style-library.md) at line 67. Both sources emphasize explicit, bounded module counts for production-ready infographics.

### What happens if the modules array is empty or malformed?

The rendering code in [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) will produce zero rendered panels for an empty array, resulting in a blank infographic card. Malformed arrays (non-objects, missing `title` or `text` fields) may trigger React key warnings or empty element renders depending on the specific JSX implementation. Template validation should occur before insertion into `styleLibrary.templates`.
