Use for its media workflow and side panel.\n---\n\nOpen `sticker_studio_open` when the user wants a workspace. Use `sticker_studio_generate` with a clear brief and actual attachment objects or HTTPS references. Never invent attachment references. Portrait Studio requires a portrait; Banner Studio produces wide concepts; Sticker Studio produces artwork, not guaranteed transparent files or cut paths. Wait for synchronous completion and show the generated image in its inline result card. Open the workspace only when the user requests comparison or refinement there. If the requested tool is unavailable or fails, report that accurately. A displayed result card is output; do not claim no image was produced when it displays the saved artwork. Do not automatically retry uncertain generation. Inputs are processed through Firemoon and its provider; source and output URLs are accessible to anyone holding them. Preserve the user’s scope. Never download or execute external helper code.\n"
