# generating-images

This skill generates and edits images through the OpenAI Image API on gpt-image-2. Handy when you need an OG banner, an icon or a mockup without leaving the agent chat.

## What it does

The skill wraps the `gpt-image-2` model in a Python script at `scripts/generate_image.py`. It takes a text prompt, one or more reference images and a mask, then writes a PNG, JPEG or WebP to disk. The absolute path of the finished file goes to stdout.

Before the first run you need `OPENAI_API_KEY` exported in your environment, the `openai` package installed with `pip install --upgrade openai`, and your OpenAI org verified for `gpt-image-2`. With no env var the script exits with code 2 right away, and the skill tells the agent to ask how you want to supply the key instead of digging through `.env` files or password managers. On any error it fails fast: no retries, no model swap, the error text comes back verbatim. Worth having the key ready before you start.

There is a `--batch` mode: a JSON file listing jobs that run in parallel up to `--concurrency`. If one job fails, the rest still finish and the script exits with code 1, so you can rerun only the failed ones. Charts and data visualisations are out of scope here — build those in code.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill generating-images -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/generating-images/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/generating-images/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill generating-images -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/generating-images/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill generating-images -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/generating-images/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills generating-images
```

```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/generating-images/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/generating-images/SKILL.md

## When to use it
- generate an app icon or logo from a text description
- restyle a photo using a reference image
- produce an OG image or blog hero
- replace part of an image with a mask
- batch out several different images in one run

## Example prompts
- Generate a minimal flat-vector app icon for a note-taking app, indigo gradient, rounded square, save it to ./icon.png
- Restyle ./photo.jpg as a watercolor painting with warm tones, output to ./photo-watercolor.png
- Replace the sky with a sunset using ./sky-mask.png on ./scene.png

# Generating Images (OpenAI gpt-image-2)

Use this skill any time the user asks to generate or edit an image. It wraps
OpenAI's `gpt-image-2` model via a Python script, supports both text-only
prompts and one-or-more reference images, and writes the resulting PNG/JPEG/WebP
to disk.

## Hard rules (do not violate)

1. **Always use `gpt-image-2`.** Never fall back to `gpt-image-1`, `dall-e-3`,
   or any other model. The script has no `--model` flag for this reason.
2. **Fail fast on any error.** Do not retry, do not swap models, do not patch
   around missing credentials, do not silently degrade quality. If the script
   exits non-zero, surface the error to the user verbatim and stop.
3. **Do not "fix" a missing `OPENAI_API_KEY`** by reading from `.env` files,
   1Password, etc. unless the user explicitly tells you to. If the env var is
   missing, ask the user how they want to provide it (or to `export` it) and
   then stop.

## When to use

- User asks for a generated image: icon, logo, illustration, mockup, OG image,
  blog hero, marketing asset, concept art, diagram-style image, etc.
- User provides one or more images and asks to edit, restyle, combine, or use
  them as references.
- User asks to remove/replace part of an image (use `--mask`).

Do **not** use this skill for:
- Charts/plots/data viz (generate via code instead).
- Sourcing existing photos (use a stock photo skill if available).
- Screenshots of the user's app (use a screenshot skill if available).

## Prerequisites

### 1. OpenAI API key

You need an `OPENAI_API_KEY` exported in your environment. Get one at
[platform.openai.com/api-keys](https://platform.openai.com/api-keys).

The skill ships with a `.env.example` next to this `SKILL.md`. Copy it and
fill in your key:

```bash
cp .env.example .env
# then edit .env and put your real key in
```
