}10 tools, verified live
list_appsread-onlyThe user's apps in Agent C, with how many screenshots each has uploaded.
add_appAdd an app by its App Store link (imports name, icon, description), or by name if it isn't released yet. Importing a live app takes ~10-30s; poll list_apps until status is 'ready'.
get_upload_linkBest way to upload screenshots from files on disk: returns a one-time URL (valid 30 min) to POST the image files to with curl (multipart field 'files', up to 10 per request). Use this instead of upload_screenshots when you have a shell, so large images don't pass through the conversation.
upload_screenshotsUpload 1-10 raw screenshots of the app (plain captures of the real UI, ideally 4-10, in the order you'd like them considered). Each item is base64 image data (PNG/JPEG) or a public https URL. By default replaces the app's screenshot library.
design_setClaude art-directs a full App Store screenshot set from the uploaded screenshots: opening shot, headline per slide, close-ups, palette. Returns watermarked preview images, the slide list and a link to open it in the Agent C studio. Takes ~40-60 seconds.
get_setread-onlyCurrent slides, unlock status and fresh preview images for a set.
edit_setChange one slide (headline, subline, screenshot, layout, position, or remove it), the opening shot, the device size, or the App Store header (header_*). Re-renders previews. Free.
unlock_setUnlock clean, full-resolution files for a set. Uses a free unlock if the user has one; otherwise returns a $9.99 Stripe checkout link the USER must open and pay. Studio subscribers are already unlocked. Ask the user before calling.
export_setRender the unlocked set at exact App Store pixels without watermark and return download links (valid 7 days). Includes the product page header (3840x1646) and search-results image (3840x2560) when the set has a header.
send_to_app_storecan modifyUpload the unlocked set into the app's editable version in App Store Connect, replacing that language's screenshots for this device size. Never submits for review. Requires the user to have connected App Store Connect in Agent C. If the app has no editable version, ask the user, then call with create_version=true.
