GPT Image Skill

Generate or edit images using OpenAI's GPT Image models through a bundled Python script.

Resolve the skill directory

Before running any command, resolve the absolute directory containing this SKILL.md and refer to it as <skill-dir>. Never assume the current working directory is the Skill directory. Keep user input and output paths relative to the user's working directory unless the user requests another location.

Requirements

1. OPENAI_API_KEY: Must be configured in ~/.gpt-image.env or export OPENAI_API_KEY=<your-key>
2. OPENAI_API_BASE (optional): Custom API base URL for compatible endpoints (e.g. Azure OpenAI, proxies). Set in ~/.gpt-image.env or export it.
3. Python3 with dependencies: openai, httpx, python-dotenv. Install via python3 -m pip install -r "<skill-dir>/requirements.txt" if not installed yet.
4. Executable: <skill-dir>/gpt_image.py
