App Store Screens

Take a brand plus real product screens and produce a 5–6 screen App Store campaign at iPhone 6.9" size (1290×2796). The product screens can come from raw exports, Figma/source files, or a public App Store listing fetched through Pika MCP. Story-driven, splashy, strict to the brand.

This is a sister skill to build-a-brand — it consumes that skill's brand.md spec, but works equally well with any brand spec the user supplies.

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 150-300 credits (~$1.50-$3.00) for a typical 5-6 screen set using GPT-image-2, PNG renders, post-render analyze_media QA, and full-resolution individual PNG QA. This is below $5, but Reply proceed to continue or cancel to 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.

The deliverable

5 or 6 PNGs, numbered, saved to ~/Desktop/[app-name]-app-store-screens/ (or wherever the user prefers):
