Tools

Only the tools the agent can actually call.

The Tools page lists capabilities Galaxy supports. It is not the full Magica marketplace.

Supported tools

Tool	What it does
GPT Image 2	Generate a new image from a prompt, or edit an image when you attach one
Crop Image	Crop by percent or pixel rectangle
Merge Videos	Concatenate 2–100 videos with none, fade, or dissolve
Web search	Look up current sources
Sandbox	Run short Python
Load skill / read skill asset	Follow a shipped skill (image-editing, sandbox-python, video-merge)

The agent calls these from chat when they are needed. A generate-image card shows the prompt as soon as it is decided, including while the image is still generating. The same prompt is stored on the tool result for the finished card and image preview.

OpenRouter writes the reply. Magica tools only run when the turn needs image or video work.
