Step 2 of 3.\n\nReturns immediately with a review link while the set is designed in the background (about 1–2 minutes) — then call get_screenshot_set to wait for it. The result is three art directions sharing one set of headlines, each fully editable in the LaunchShots editor.\n\nWrite app_description from the real source: the README, store listing, or the app's own copy — what it does, who it's for, and what makes it different. Specific beats generic; the headlines are only as sharp as this.\n\nEither pass set_id from prepare_screenshot_upload (preferred), or pass the screenshots inline as base64 if you cannot run shell commands (keep each under ~1 MB). Calling again with the same set_id after a failure retries it; nothing is charged for a failed run.",
