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
TV Mirror+ for Chromecast is the easy screen sharing tool to mirror your iPhone or iPad screen and sound on Chromecast in Full HD Quality. Mirror photos, videos, games, websites, apps, presentations, documents and spreadsheets on Chromecast. * Supported Chromecasts: Chromecast, Chromecast Ultra and all generations of the Chromecast family * Supported TVs and other devices: Xiaomi MI Box, NVIDIA Shield TV and all TVs with Google Cast or Chromecast built-in, e.g. Sony, TCL, Vizio, Sharp, Philips, Hisense, Skyworth, Soniq * Your iPhone/iPad and your Chromecast must be connected to the same wifi to enable screen mirroring. Please do not use VPN, Proxy, VLANS and Subnets. * Latency is supreme (below 1 second) when you have good wifi network conditions * No hidden subscriptions or costs * If a third party app, for example Spotify, does not mirror sound correctly, please FORCE CLOSE and restart Spotify while the mirroring session is active. Please check the Apple Support page to learn how to FORCE CLOSE an app: https://support.apple.com/en-us/HT201330 * Black screen issues: Some third party apps prevent screen mirroring. When you try to mirror them, you will just see a black screen on your TV, for example with Netflix and Disney+. This is a restriction chosen by Netflix and others, so we cannot fix it at the moment. If you like the app and our constant work on it, please give the app a positive rating on the App Store. Many thanks in advance from the development & support team.

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

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.
