**The freestylefly/awesome-gpt-image-2 repository is an open-source "Prompt-as-Code" platform that curates 500+ community-generated image generation cases into reusable industrial-grade templates for OpenAI GPT-Image 2 and 2.5 models.**

This project combines a React-based web gallery with an extensible Agent Skill system, allowing developers and AI assistants to programmatically access style libraries, scene tags, and battle-tested prompt patterns. According to the freestylefly/awesome-gpt-image-2 source code, the architecture separates concerns into a Vite-powered frontend, Supabase backend services, and structured knowledge assets stored as JSON and Markdown.

## Core Architecture

The repository follows a three-tier architecture that separates presentation, data persistence, and domain knowledge.

### Frontend Layer

The user interface is a **React single-page application** built with Vite. The core application logic resides in [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx), which handles language switching, case browsing, prompt copying, and image generation controls. Styling is centralized in [`src/styles.css`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/styles.css), while routing and state management coordinate interactions between the visual gallery and backend APIs.

### Backend Services

**Supabase** provides authentication, user credit tracking, and RPC API endpoints. The client initialization and helper functions live in [`src/supabaseClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/supabaseClient.js), wrapping database queries and auth flows. Image generation requests route through the APIMart API via [`src/apimartClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/apimartClient.js), which manages personal API key handling and task polling loops. Shared constants such as pricing snapshots and error codes are defined in [`shared/apimart.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/shared/apimart.js) for consistency across the application.

### Knowledge Assets

The repository stores domain knowledge in structured formats:

- **[`data/cases.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/cases.json)** – Drives the visual gallery with 544+ documented generation cases, including prompts, metadata, and categorization tags.
- **[`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md)** – Contains 21 industrial prompt templates with "pitfalls" guides explaining common failure modes and optimization strategies.
- **`agents/skills/gpt-image-2-style-library/`** – Houses the NPM package source that exposes style libraries to AI agents programmatically.

## The Agent Skill System

A distinctive feature of **freestylefly/awesome-gpt-image-2** is its **Agent Skill** implementation, packaged as `gpt-image-2-style-library`. This NPM module allows AI assistants like Claude Code and Codex to automatically select appropriate styles, templates, and scene tags when generating prompts.

The skill documentation in [`agents/skills/gpt-image-2-style-library/SKILL.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/agents/skills/gpt-image-2-style-library/SKILL.md) defines the contract for agent interactions, specifying available categories, style parameters, and scene descriptors. Agents invoke this skill to construct contextually appropriate prompts without manually browsing the web gallery.

Install the skill globally for agent access:

```bash
npx skills add freestylefly/awesome-gpt-image-2 --skill gpt-image-2-style-library --agent claude-code codex --global --yes --copy

```

## Industrial-Grade Prompt Templates

The project elevates prompt engineering from trial-and-error to systematic reuse. The [`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md) file contains curated templates organized by domain—such as Architecture & Spaces, Product Photography, and Character Design—each annotated with:

- **Positive descriptors** that enhance generation quality
- **Negative prompts** that avoid common artifacts
- **Parameter recommendations** for GPT-Image 2 specific settings

These templates distill community wisdom from the 500+ cases into reproducible patterns, reducing the iteration cycle for production image generation workflows.

## Getting Started

### Web Gallery Usage

Browse the deployed gallery to explore cases, copy prompts directly, or generate images using stored credits. The frontend communicates with Supabase for authentication and user data, while generation requests proxy through APIMart endpoints configured via environment variables.

### Programmatic Integration

Use the NPM package in Node.js applications to generate prompts dynamically:

```javascript
import { generatePrompt } from 'gpt-image-2-style-library';

// Create a city-life system-map prompt
const prompt = generatePrompt({
  category: 'Architecture & Spaces',
  styles: ['Neon', 'Isometric'],
  scenes: ['Night City'],
  tags: ['city life', 'system map']
});

console.log(prompt);

```

### Direct API Access

Fetch specific cases from the public API endpoint used by the web interface:

```javascript
fetch('https://gpt-image2.canghe.ai/api/cases/532')
  .then(response => response.json())
  .then(caseData => {
    console.log('Case title:', caseData.title);
    console.log('Prompt:', caseData.prompt);
  });

```

## Frequently Asked Questions

### What is the primary purpose of freestylefly/awesome-gpt-image-2?

The repository serves as a **Prompt-as-Code** platform that transforms community-generated image examples into reusable, programmatically accessible prompt templates for OpenAI's GPT-Image 2 models. It combines a browsable web gallery with an NPM package that AI agents can invoke to select appropriate styles and generate optimized prompts automatically.

### How does the Agent Skill system work?

The **Agent Skill** is implemented as the NPM package `gpt-image-2-style-library` located in `agents/skills/gpt-image-2-style-library/`. AI assistants like Claude Code consume the skill definition in [`SKILL.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/SKILL.md) to understand available categories, styles, and scene tags. When an agent needs to generate an image prompt, it calls the skill's functions—specifically `generatePrompt()`—which returns a formatted prompt string incorporating best practices from the template library.

### Where are the prompt templates stored and how are they organized?

Industrial-grade prompt templates reside in **[`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md)**, organized by domain categories such as Architecture & Spaces and Product Photography. Each template includes positive descriptors, negative prompts to avoid artifacts, and GPT-Image 2 specific parameter recommendations. The web gallery displays individual cases from **[`data/cases.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/cases.json)**, which contains over 544 entries with full prompt text and metadata.

### What backend services does the platform use?

The platform relies on **Supabase** for authentication, user credit tracking, and database operations, initialized in [`src/supabaseClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/supabaseClient.js). Image generation requests route through the **APIMart API** via [`src/apimartClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/apimartClient.js), which handles personal API key management and asynchronous task polling. Payment processing for membership and credits integrates Stripe and Alipay, with analytics tracked through GA4.
