App Sizzle — GPT-Image-2 Enhanced iOS App Teaser
Generate a polished 15-second app teaser from real app screens. Each selected screen is passed through GPT-image-2 before Seedance so compressed captures become cleaner references without inventing UI.
Cost transparency gate
Before any paid MCP call, call identity_balance({verbose: true}) once. Surface the current balance, recent burn rate, and remaining runway, then gate the run with this exact message:
Estimated cost: about 3,000-4,000 credits (~$30-$40) for a typical run with screenshot enhancement plus Seedance video. This exceeds $5, so Reply
proceedto continue orcancelto stop.
Do not call any paid MCP tool until the user replies proceed. If the user replies cancel, stop without generating. For non-interactive --quick or --config callers, require cost_ack=proceed in the config; if it is absent, stop with the estimate instead of spending credits.
Generation contract: use resolution="1080p", duration=15, and sound=True. Skip fast=true because it caps Seedance at 720p. The skill owns duration and sound so the user only has to supply app identity, screens, logo, and aspect ratio.
The visual aesthetic is derived from the app's personality — not defaulted to liquid glass. The agent reads the app's soul from its icon, screenshots, and category, then chooses a treatment. The user provides the app identity and assets; the agent decides everything else (mode, prompt, camera, style).
