Generate Image Skill

Generate images from natural language prompts using OpenAI's image API.

Script location

Installed by install.sh — path depends on your chosen install location. Default: ~/.claude/skills/openai-image-skill/openai-image-skill.mjs

If the script is not found

If openai-image-skill.mjs is missing at the expected path, install it non-interactively:

git clone https://github.com/dkarski/openai-image-skill.git /tmp/openai-image-skill
bash /tmp/openai-image-skill/install.sh --default
rm -rf /tmp/openai-image-skill

Then retry the original image generation command.

When this skill applies

The user wants to generate, draw, or create an image — in any language.

How to invoke

Run the script with the Bash tool:

{{INVOKE_CMD}} "PROMPT" [--model=X] [--quality=low|standard|hd] [--size=X] [--count=N] [--output=X]

Extracting arguments from the user message

User says	Map to
The description of what to draw	`"PROMPT"` (required, always quoted)
"using dall-e-2" / "model dall-e-3"	`--model=dall-e-2`
"1792x1024" / "landscape" / "square"	`--size=1792x1024` (use exact WxH)
"fast" / "cheap" / "draft" / "low quality"	`--quality=low`
"best quality" / "high quality" / "hd" / "detailed"	`--quality=hd`
"3 variants" / "give me options" / "multiple versions"	`--count=3`
"save as cat.png" / "output: logo.png"	`--output=cat.png`

If the user does not specify a flag, omit it — the script uses the saved default.

Size hints

square → 1024x1024
landscape → 1792x1024
portrait → 1024x1792

Other commands

{{INVOKE_CMD}} list-models
{{INVOKE_CMD}} set-default dall-e-3
{{INVOKE_CMD}} update

What to report back

After the script exits successfully, tell the user:

The saved file path (from Saved: ... line in stdout)
The model used
The size

If the script prints an error, show the error to the user and suggest the fix (e.g. set OPENAI_API_KEY).

Example invocations

{{INVOKE_CMD}} "a futuristic city at night"
{{INVOKE_CMD}} "mountain landscape at sunset" --quality=hd
{{INVOKE_CMD}} "logo: minimalist fox" --model=dall-e-3 --count=3 --output=logo.png
