Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Differentiate and validate
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description
IMPORTANT! PLEASE READ THIS FIRST! I kindly ask you to ASK FOR HELP in case of any trouble. You can always write to [email protected] or [email protected]. PLEASE help make Stream Player a better product with your valuable feedback! I will do my best to answer within a day! Stream Player for iPhone is the iOS version of the lightweight Mac internet stream player, featuring several smart tools to aid OneClick stream playing in a dedicated player window. Currently, there are two ways to start playing streams: 1. Use the “Add to Stream Player” or “Watch Later in Stream Player” options available in the iOS App Action and Share extensions. 2. Set up iCloud Drive to synchronize your stream lists between the Mac app and your iOS devices. You can download the Mac version at: https://itunes.apple.com/us/app/stream-player/id931235000?ls=1&mt=12 Currently available features • iCloud Drive sync to share and synchronize stream lists between iOS and Mac devices. • Customizable web stream content behaviors: enable or disable navigation and editing. • Ad blocking in stream content. • Support for background stream playback — ideal for listening to, for example, podcasts on the road. NOTE: To continue playing a stream in the background, you must restart playback after Stream Player goes into the background. To do this, press the play button on your headphones or swipe up the Control Center and press the play button. • Playback of multiple streams simultaneously on iPad devices running iOS 11.0 or later. • Supported streams: ⁃ Safari-supported common streams over HTTP (HLS, WebRTC, fMP4, etc.) ⁃ RTMP ⁃ RTSP ⁃ MPEG-DASH (currently macOS only — stay tuned!) (common codecs: VP8, VP9, H.264, H.265, etc.) Any feature requests or bug reports are highly welcome!

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

BUILD KIT DIFFICULTY
Intermediate
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
