image-gen

Original：🇺🇸 English

Translated

Generate and edit images using AI. Use when users ask to: create/draw/generate images, edit/modify photos, change backgrounds, add elements to images, create avatars, make logos, etc. Covers requests like 'draw a cat', 'change the background to blue', 'generate a logo'. NOT for selfies — use the selfie skill for 'send a selfie', 'send me a selfie', 'take a selfie'.

Image Generation & Editing Skill

Use the

alma image

command to generate or edit images. It handles API keys, model selection, and everything automatically.

Generate an Image

bash

alma image generate "detailed prompt describing the image"

The command outputs the file path to stdout. Then use

alma send photo <path>

to deliver it to the user.

Edit an Image

bash

alma image edit /path/to/source.jpg "describe the changes you want"

Selfies

For selfies, use the selfie skill instead — it handles face consistency, album management, and photorealistic prompting automatically.

Tips

Always write detailed prompts: style, setting, lighting, composition
After generating, send the image with
```
alma send photo <path>
```
— do NOT just paste the path in text
If you get rate limit errors, wait a moment and retry
The command auto-selects the best available Gemini image model
Always save selfies to build up your album for better face consistency over time
The
```
--reference
```
flag works with
```
generate
```
to inject a reference image for the AI to maintain appearance
NEVER assume the API is broken based on past errors. API errors (rate limits, temporary failures) are transient. ALWAYS try the command — never tell the user "the API is down" or "the key is invalid" without actually running the command first. Each attempt is independent.
