# 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.

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