GPT Image 2 prompt gallery, image prompt library, agentic skill, and CLI for OpenAI image generation/editing

What it solves

This project provides a curated library of high-quality prompts and a set of tools to make the most of OpenAI's gpt-image-2 model. It solves the problem of "prompt engineering" for image generation by providing a gallery of proven prompts for various styles (e.g., research paper figures, UI mockups, photography) and a CLI/agent skill to execute them easily.

How it works

The project operates through three primary interfaces:

  1. Prompt Gallery: A curated collection of prompts organized by category (e.g., Anime, Gaming, Typography) with metadata on size and quality settings.
  2. CLI Tool: A command-line interface (gpt-image) that allows users to generate images from text, perform reference-based edits (single or multi-reference), and handle mask-based inpainting using the OpenAI API.
  3. Agentic Skill: A plug-and-play skill folder that can be integrated into agent runtimes like Claude Code, Codex, OpenClaw, and Hermes Agent, allowing these agents to generate images using natural language requests.

Who it’s for

  • AI Image Creators: Users who want a starting point for high-quality image generation without trial-and-error prompting.
  • Agent Users: People using AI agents (like Claude Code or Codex) who want to give their agent the ability to generate images.
  • ** uma Research/Design Professionals:** Professionals needing reference sketches, UI mockups, or style targets for academic papers or posters.

Highlights

  • Multi-Reference Editing: Supports using multiple input images to combine elements (e.g., placing a subject from one image into another).
  • Agent Integration: First-class support for installation into various agent runtimes via a standardized skill system.
  • Comprehensive Reference Material: Includes a detailed prompt-craft checklist and a verbatim capture of the OpenAI cookbook for image generation.
  • Flexible CLI Parameters: Fine-grained control over image size, quality (low/medium/high), format, and moderation settings.

    JuneYaooo/gpt-image2-ppt-skills

    gpt-image2-ppt-skills is a Python skill for multimodal AI agents that uses OpenAI’s gpt‑image‑2 model to generate high‑quality 16:9 slide images and package them into a .pptx file. It supports a visual‑first mode and an optional editable mode that reconstructs slides into native PowerPoint objects. Users can create new decks, clone existing .pptx templates, or edit specific slide elements via natural‑language prompts. Installation is done by asking a supported agent to install the skill or by running a provided script; an OpenAI API key and a local PowerPoint/Keynote/LibreOffice renderer are required. The project is Apache‑2.0 licensed.
