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

D1 Baseball Full Season This app requires the user to buy an in-app subscription on an annual basis. This subscription enables use of the D1 Baseball app which provides up-to-date scores, standings, and schedules for Division I College Baseball. Once subscribed, you will be able to view information about your favorite Division I College Baseball teams. While viewing team standings, by conference, you can select teams as favorites. Games for your favorite teams will show up first in the scores view. You can also receive alerts, in the form of push notifications, for selected teams. The subscription lasts for the entire college baseball season, including playoffs through the Division I College World Series. The subscription will remain active until right before the next season begins. An active subscription enables all features of the app. The price of the annual subscription is $7.99 US. Payment will be charged to your iTunes Account at confirmation of purchase and the subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Your account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal. Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. To set team preferences, simply tap on a team that's listed in the Standings view. From there you can set a team as a Favorite (gets displayed first in the Scores view) or Notify (gets push notifications sent to you for this 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.

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.
