v1.0.0: built on the day Images 2.5 shipped

Prompt-writing skill for OpenAI GPT Image models, built 8 September 2026 against the official documentation.

What it does. You describe what you need in plain language. It returns an English prompt in seven labeled blocks, a settings block for your surface (ChatGPT app, OpenAI API, or a hosted platform), and three concrete levers for the next round.

What is covered

• gpt-image-2.5-flare and gpt-image-2.5-sunburst, plus gpt-image-2
• size rules that trip people up: multiples of 16, aspect ratio within 3:1, variable behavior above 2K
• 16 input images at 50 MB each, masks that need an alpha channel
• quality levels including xhigh and max, transparent backgrounds, token pricing
• five failure modes with fixes, including edit drift
• seven ready skeletons: poster, article cover, product shot, portrait, infographic, logo, UI mockup

Install. For claude.ai, download gpt-images.zip below and upload it in Settings, Capabilities. For Claude Code, git clone https://github.com/lukasersil/gpt-images.git ~/.claude/skills/gpt-images.

It writes prompts. It does not generate images.
