"longDescription": "Create editable social media graphics from a description. Make an Instagram post, turn supplied content into an Instagram or LinkedIn carousel, or design a YouTube thumbnail, flyer or banner.\n\nUse your Krumzi brand colors, fonts and logo. Find saved designs, refine their text and layout, generate images to use in a design, and open the result in Krumzi to edit individual layers.\n\nSave the displayed preview as a JPG, or export single-image designs as PNG, JPG, WebP or PDF. Carousels and multipage documents export through this connection as individual JPG pages. Their previews show the combined design. Standalone AI images are raster assets. Preview and export links are accessible to anyone who has the URL.\n\nConnect an existing Krumzi account with access to the design tools. Krumzi accounts require users to be 18 or older. AI generation and edits use your account's credits; previews and exports can use trial render allowances. This connection supports still images, carousels and documents; it does not create videos, publish or schedule social posts, or manage billing.",

Call generate_design with that brand_id, format=image, width=1080, height=1080 and the requested copy. Poll get_design with the returned design_id no faster than every 20-30 seconds. A pass needs nonzero element_count, the requested copy and brand styling visible in the preview, canvas 1080x1080, and returned preview_url/editor_url. Opening editor_url must show editable layers. A queued or ready status alone is not success; errors must be explained without claiming a completed design."

Call export_design with the same id and format=urls only after generation has stopped and content is verified. Return exactly five URLs from urls, in slide order. Verify they are accessible images; reported output dimensions must match the downloads and width be at most 1440 px with the slide aspect ratio preserved. Do not claim LinkedIn publication, a PDF, or full-resolution PNG exports."

Export with format=urls and return exactly two accessible page-image URLs plus editor_url. Output is social-sized JPEG pages with width at most 1440 px and preserved A4 aspect ratio.

Poll get_design at 20-30 second intervals and compare against before_preview_url (or the initial get_design preview if the before preview is unavailable), verifying 'Now Open' and unchanged 1600x600 canvas/layout. Export with format=png, scale=1 and the same id. Return actual url/editor_url. An unchanged preview, preview error or mere lock release must not be reported as a successful edit; report uncertainty and do not silently repeat a charged edit."
