**The GPT-Image2 agent skill library is a reusable skill package that equips AI agents with a structured, repository-backed knowledge base for generating high-quality image-generation prompts.**

The GPT-Image2 agent skill library lives in the `freestylefly/awesome-gpt-image-2` repository and serves as a bridge between static style definitions and dynamic agent reasoning. This library transforms the centralized [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) catalog into an actionable tool that agents like Claude Code, Codex, or any `.agents`-compatible runtime can invoke to produce production-ready prompts instantly.

## Architectural Components

### Centralized Data Source

At the foundation lies [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json), the single source of truth containing **visual-style definitions**, **template categories**, **scene tags**, pitfalls, and concrete example cases. This JSON file drives both the website UI and the agent skill, ensuring agents always access the latest community-curated styles without version drift.

### Skill Definition

The [`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) file declares the skill's purpose, workflow, and output defaults. According to this specification, the agent executes a four-step pipeline:

1. **Detect** the input language automatically
2. **Identify** the target output type requested by the user
3. **Match** the request against template categories → visual-style tags → scene tags → example cases
4. **Compose** a production-ready GPT-Image2 prompt including composition details, materials, aspect ratios, and negative constraints

### Generation Pipeline

The `scripts/generate-style-skill.mjs` script reads [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) and produces a ready-to-publish skill package containing [`SKILL.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/SKILL.md), assets, and generated reference files. Invoke this build process via:

```bash
npm run generate:style-skill

```

### Installation Infrastructure

Two scripts handle deployment to local agent runtimes:

- `scripts/install-style-skill.mjs` copies the generated skill into local agent directories (`~/.codex/skills`, `~/.claude/skills`, `~/.agents/skills`)
- `agents/skills/gpt-image-2-style-library/bin/install.mjs` provides a CLI wrapper (`gpt-image-2-style-library install [all|codex|claude-code|agents]`) that validates targets and triggers the copy operation

Run the installation via:

```bash
npm run install:skill

```

Or use the CLI directly after the skill is built:

```bash
gpt-image-2-style-library install all

```

### Package Distribution

The [`agents/skills/gpt-image-2-style-library/package.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/agents/skills/gpt-image-2-style-library/package.json) declares the skill as a distributable npm package, enabling installation via `npx skills add …` or direct publishing to npm registries.

## Installation Methods

You can deploy the GPT-Image2 agent skill library using three distinct approaches depending on your environment.

**Global npx installation** (recommended for immediate use across multiple agents):

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

```

**Local npm workflow** (for development or customization):

```bash
npm run generate:style-skill   # Creates skill bundle from data/style-library.json

npm run install:skill          # Copies to ~/.codex/skills, ~/.claude/skills, etc.

```

**Direct CLI invocation** (after local installation):

```bash
gpt-image-2-style-library install all

```

## Runtime Usage

Once installed, agents invoke the skill programmatically. According to the source implementation 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), the workflow enables language-aware prompt generation:

```javascript
await agent.runSkill('gpt-image-2-style-library', {
  request: '生成一个未来城市的概念海报',
  language: 'zh'
});

```

The skill processes the request through its four-step reasoning pipeline, matching the input against the centralized JSON catalog to emit a complete GPT-Image2 prompt with specific composition guidance, material specifications, aspect ratio constraints, and negative prompts to avoid.

## Summary

- The **GPT-Image2 agent skill library** transforms static JSON style definitions into dynamic agent capabilities for automated prompt engineering.
- The architecture centers on [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) as the single source of truth, consumed by both human-facing UIs and machine agents to ensure consistency.
- **Installation scripts** (`scripts/install-style-skill.mjs` and `bin/install.mjs`) deploy the skill to local agent runtimes including Claude Code, Codex, and generic `.agents` directories.
- The **generation pipeline** (`scripts/generate-style-skill.mjs`) ensures the skill package always reflects the latest community-curated styles without manual synchronization.
- Agents invoke the skill via standardized APIs to produce production-ready image-generation prompts structured with composition details, materials, aspect ratios, and negative constraints.

## Frequently Asked Questions

### What is the primary purpose of the GPT-Image2 agent skill library?

The library provides AI agents with a structured, repository-backed knowledge base for generating high-quality image-generation prompts. It bridges the static [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) catalog with dynamic agent reasoning, enabling Claude Code, Codex, and compatible runtimes to understand user intent, select appropriate visual styles, and emit production-ready GPT-Image2 prompts complete with composition and constraint specifications.

### Which file contains the master catalog of styles and templates?

The [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) file serves as the canonical source for all visual-style definitions, template categories, scene tags, and example cases. This JSON file drives both the website UI and the agent skill, guaranteeing that agents always reference the latest community-curated content without requiring manual updates to the skill package itself.

### How do I install the skill for local AI agents?

You have three installation options: use `npx skills add freestylefly/awesome-gpt-image-2` for immediate global installation across multiple agent types, run `npm run generate:style-skill` followed by `npm run install:skill` to build and deploy locally from source, or execute `gpt-image-2-style-library install all` via the CLI wrapper after initial setup. These commands write files to `~/.codex/skills`, `~/.claude/skills`, and `~/.agents/skills`.

### Can I use this skill with any AI agent runtime?

Yes, the skill supports any runtime compatible with the `.agents` skill specification, including Claude Code and Codex. The [`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) definition follows standard agent-skill conventions, and the installation script targets multiple agent directories simultaneously, making the skill portable across different AI agent frameworks that support the skill manifest format.
