AI Coding Tools That Support the GPT-Image2 Style Library Skill

Claude Code, Codex, and Cursor natively support the GPT-Image2 style library skill through the standardized skills framework, allowing developers to generate AI image prompts directly within their coding environment.

The GPT-Image2 style library skill packages visual prompt engineering capabilities into a reusable agent module compatible with local AI coding assistants. According to the freestylefly/awesome-gpt-image-2 repository, any AI coding tool that understands the skills ecosystem can consume this library to produce structured, style-consistent image generation prompts without context switching.

Supported AI Coding Assistants

The repository explicitly identifies three major tools that integrate natively with the GPT-Image2 style library skill. Each tool consumes the skill through the same underlying skills package but stores the configuration in agent-specific directories.

Claude Code

Claude Code installs the skill via the skills CLI and registers it within the Claude Code interface. When you run the installation command with the --agent claude-code flag, the skill metadata copies to the appropriate Claude Code configuration directory, making the gpt-image-2-style-library command available directly in chat sessions.

Codex

OpenAI Codex consumes the same skill format, writing the skill files to ~/.codex/skills after installation. Once registered, the skill appears in the Codex UI as an available tool, allowing you to invoke style library functions during coding sessions. The installation process uses identical npx skills add commands but targets the --agent codex parameter.

Cursor

Cursor also participates in the skills ecosystem. After running the installation script, the skill appears under Cursor’s "Agent Skills" panel. Cursor reads the skill definition from agents/skills/gpt-image-2-style-library/SKILL.md to understand the available functions and their parameters.

Installation Methods

You can install the GPT-Image2 style library skill using three distinct approaches depending on your workflow preferences.

Using the Skills CLI (Recommended)

The skills package provides a unified CLI for managing agent capabilities across multiple tools. This method supports installing the skill for Claude Code, Codex, and Cursor simultaneously.

Install the skill for specific agents:

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

Install for all local agents at once:

npx skills add freestylefly/awesome-gpt-image-2 \
    --global --all --copy

Using npm Global Installation

For command-line usage independent of any specific AI coding editor, install the package globally from the npm registry:

npm install -g gpt-image-2-style-library
gpt-image-2-style-library install all

This copies the skill files to all detected agent directories while also making the CLI available system-wide.

Using npx Without Installation

To run the skill without permanent installation, use npx to execute the package directly:

npx gpt-image-2-style-library install all

This method is ideal for CI/CD pipelines or temporary environments where you want to avoid global package pollution.

Core Skill Architecture

The GPT-Image2 style library skill relies on three critical files that define its behavior and data sources. These files constitute the integration points that Claude Code, Codex, and Cursor use to understand and execute the skill.

Skill Definition File

The agents/skills/gpt-image-2-style-library/SKILL.md file contains the skill's metadata, workflow definitions, and output format specifications. This Markdown file tells AI coding assistants exactly how to invoke the skill, what parameters to expect, and how to structure the generated image prompts.

Data Source

The data/style-library.json file serves as the canonical reference for available styles, categories, and example cases. Both the web interface and the agent skill read from this JSON file to ensure consistency between manual browsing and AI-assisted generation.

Package Configuration

The root package.json defines the npm scripts that build and distribute the skill, specifically the generate:style-skill script that compiles the skill files. It also lists dependencies required for the overall project, ensuring the skill has access to necessary utilities when executed in different environments.

Usage Example

Once installed in Claude Code, Codex, or Cursor, invoke the skill with natural language requests:

Use gpt-image-2-style-library to create an infographic prompt about Codex.

The AI coding assistant interprets this request using the skill definition in SKILL.md, retrieves relevant style data from data/style-library.json, and generates a formatted prompt optimized for GPT-Image2.

Summary

• Claude Code, Codex, and Cursor natively support the GPT-Image2 style library skill through the skills framework.
• Install the skill using npx skills add for multi-agent setup, npm install -g for CLI access, or npx for temporary execution.
• The skill configures itself by reading agents/skills/gpt-image-2-style-library/SKILL.md and pulling style data from data/style-library.json.
• The npm package gpt-image-2-style-library provides both the skill definitions and the command-line interface.

Frequently Asked Questions

What is the GPT-Image2 style library skill?

The GPT-Image2 style library skill is an agent capability package that enables AI coding assistants to generate structured image prompts. It encapsulates visual prompt engineering knowledge into a reusable module that Claude Code, Codex, and Cursor can invoke during development sessions.

Can I use the skill without Claude Code, Codex, or Cursor?

Yes. While the skill integrates natively with those three tools, you can use the npm CLI independently. Run npx gpt-image-2-style-library install all in any terminal to generate prompts without an AI coding assistant interface, though you will need to manually copy the output into your image generation workflow.

Where does the skill store its configuration files?

The skill writes configuration to agent-specific directories: ~/.codex/skills for Codex, the Claude Code skills directory for Claude Code, and Cursor’s "Agent Skills" panel storage for Cursor. The source definitions remain in agents/skills/gpt-image-2-style-library/ within the repository.

How do I update the skill to the latest version?

Run the installation command again with the latest flag, or use npm update -g gpt-image-2-style-library if you installed globally. For CLI-based updates, execute npx skills add freestylefly/awesome-gpt-image-2 --skill gpt-image-2-style-library --force to overwrite existing skill files with the latest version from the repository.
