| Requires pip/uv | ✅ Yes | ✅ Yes |
| Works on Fly.io free | ✅ Yes (with pip) | ❌ Fails |
| Works in containers | ✅ Yes (with pip) | ❌ Often fails |
| Image generation | ✅ Full | ✅ Full |
| Image editing | ✅ Yes | ✅ Yes |
| Setup complexity | Install SDK + set API key | Install packages first |
Bottom line: This skill uses the OpenAI SDK, so you must install openai once with pip.
