Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Lose Yourself Without Getting Lost. This handy application presents you several self-guided city walks, featuring the best of the city. It comes with detailed walk route maps and powerful navigation features enabling you to see the best of the city. No need to hop on a tour bus or join a tour group; now you can explore all the city attractions on your own, at your own pace, and at a cost that is only a fraction of what you would normally pay for a guided tour. Sightseeing walks included in this application are: * Westminster Walk (10 sights) * Bridges of London (10 sights) * South Bank Walk, Part 1 (11 sights) * Harry Potter Trail (9 sights) * Shakespeare's London (6 sights) * South Bank Walk, Part 2 (7 sights) * Religious Sites (8 sights) * Holborn/Covent Garden Walk (11 sights) * Charles Dickens' London (10 sights) * Historic Pubs Walk (10 sights) * Buckingham Palace Area (7 sights) * East City of London Walk (11 sights) * Bloomsbury Museums, Part 1 (6 sights) * Knightsbridge Walk (12 sights) * Bloomsbury Museums, Part 2 (8 sights) * Gift and Souvenir Shopping (8 sights) * West End Nightlife (5 sights) * City Orientation Walk (13 sights) Discovery walks included in this application are: * Antiques Hunting Walk * Oxford Street Area Shopping * St James's Walk * Marylebone Shopping * Camden Town Markets * Shoreditch Art Street * Little Venice Walk No Data Plan or Internet is Needed, and No Roaming either. All the data used in this app is built into the software, so you can follow the city walks or use the city map without internet access or cellular data plan. No need to pay the costly roaming charges when traveling to foreign cities. The app works with your iPhone, iPod Touch or iPad. The powerful navigation assistance includes: * Walk routes clearly displayed on map. * Precise walking directions from one sight to the next. * `FindMe` displays your exact location and Auto Tracking displays your movement on the map (this feature is not supported by the iPod Touch and iPad wifi models). * Built-in compass to show you the direction. * Create your own walks to see the attractions you like. * A detailed city map which can be used independently for your other traveling needs. Please visit our website at www.GPSmyCity.com to find city walks for over 470 cities worldwide. Note: Continued use of GPS running in the background can dramatically decrease battery life. This app gives you the option to turn off the GPS tracking in the background to prolong the battery life.

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.

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.
