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

Locate every site on the United States Historic Register! The United States National Historic Register contains over 85,000 entries, each a site that has been designated as having historic value. That means that no matter where you travel in the country you are almost certainly near one or more sites on the Historic Register. Finding those sites can be difficult! Most are not marked with any kind of signage, and there is no map showing of them. Historic Register Site Finder solves that problem! Historic Register Site Finder presents the standard Apple Map, with sites in the National Historic Register marked on the map at their location. For any locale you choose or for the area around your current location, you can see what Historic sites are nearby. You can use it in two ways: "Search and Locate" mode: Search for Historic sites by state, by city or by name, or any combination of those three. You'll get a list of all the sites matching your search criteria. From that list you can see more information about a site, or you can tap a site and the map will center itself on the site you selected. "While You're Moving" mode: As you drive or walk, the map will show your current location and any Historic Sites in the area. You can zoom the map to cover a small area or larger areas around your current position. In both modes you can see where sites are located on the map, and then see more detailed information about the site by tapping the site's callout balloon. With your Historic Register Site Finder, you'll be able to locate sites on the United States Historic Register and find them as you travel across the country. Cool, eh?

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.

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.
