Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @Liu_Dong, thanks for the report!

This one is actually intentional. The AI models behind agent mode can only view raster image formats (like PNG and JPEG), so when you attach an SVG as an image, Cursor converts it to PNG so the model can actually see it. Sending the SVG through unchanged would make the request fail.

If you want the agent to work with the actual SVG source (the XML markup), add the .svg file as a file instead of an image. For example, @-mention the file from your project in the input, or just ask the agent to read the file. That way it gets the full vector source rather than a rasterized preview.
