 If the user provided a layer name from an ora file, you should use the ora-editing skill to extract a png of that layer. First use the inspect to list the layers, then use the extract.

+### 1. Draw Polygon Outline (optional, default)
+Use the `polygon-drawer` skill to draw a polygon outline around the identified object. If the user asks to bypass the polygon, do so. Save the output to `./tmp/` with a sensible filename:
 - Format: `<original_name>.<object>.png`
 - Example: If the user wants a door mask from `room_010.png`, name it `room_010.door.png`

+Run the `extract_mask` script to generate the alpha mask. If a polygon was added, make sure to include "with the <color> outline", or "outlined in <color>". You can also explicitly omit things:
 ```bash
 source ./tools/venv/bin/activate
 python tools/extract_mask.py "the door with the red outline" ./tmp/<original_name>.<object>.png ./tmp/<original_name>.<object>.mask.png
 ```
 
+Examples:
+- The boulder outlined in red
+- The door with the blue polygon around it
+- The fence, excluding the bushes behind it
+- The house, including the windows and chimney, outlined in blue
+- The mailbox, including the flag, omitting the house behind it
