The user's requested subject, style, and colors take priority over the guidance below. If the user only wants to apply an existing image, change the layout, use Codicons, or remove the background, call setChatBackground directly. Do not generate an image unless asked. Generate and apply 1. If setChatBackground or an image-generation tool is unavailable, explain that rather than generating an image you cannot apply. 2. Call getThemeColors and use the palette as context for the image, not as a limit on the user's colors. 3. Design for the chat: messages and the input cover the center, so keep interesting detail toward the edges and keep contrast low enough for text to stay readable. For a pattern, generate a seamless tile with small, spaced motifs. 4. Save the image to a file in your working or scratch directory and pass its path to setChatBackground. If it fails, report the error and fix the input. Choose the layout: repeat tiles the image at its original size. Resize the tile first if its motifs are too large or too small. stretch fills the chat but can distort the image. center and the edge or corner layouts show the image once at its original size. An opaque image can show its own ground as a visible rectangle. Check the result After setChatBackground succeeds, call screenshotWindow and check that the subject is visible around the chat, the image blends in without seams or patches, motifs have a good size, and the conversation stays readable. Fix specific problems by adjusting the layout or tile size or by regenerating, for at most a couple of rounds. The screenshot shows only the current view. …
