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

Marine Life of the North Atlantic presents easy to use and cleverly designed field guide that unveils marine life of the region from Northern Canada to Cape May, New Jersey. Marine Life of the North Atlantic is a unique tool, which you can carry in your pocket, that allows divers, students, teachers, citizen scientists, and beachcombers to have and to share information of observed marine organisms of the covered region. It is the most comprehensive field guide expertly designed for easy recording and sharing of all your observations. The book section of this app is divided into clear, color coded and easy to navigate chapters/phylum. The SEARCH feature is uniquely designed to allow you to narrow the search within each chapter or to explore the entire book. DIVE RECORD This feature is a pictorial record of the plants or animals you have seen during your dive or just a walk on the beach it is not designed to replace your traditional dive log. It is a wonderful tool for divers, citizen scientists, and lovers of nature to record their observations of marine life when and where they were found. Is a simple and easy to use function that gives you ability to keep a unique record of your personal observations and share your discoveries with others. LIFE LIST With this app you have a unique opportunity to create a personal Life List that you can sync among all your mobile devices. The Follow feature allows you to create a “bucket list” of plants and animals that you would like to see. When another user records an animal on his/her dive record that is on your Following List, you will receive a notification indicating where and when it was observed. The “Notifications” section is dedicated to inform you of all upcoming dive related activities, such as club meetings, dive trips, classes and sales. The events that you choose to save can be easily added to your personal calendar. This mobile app is a modern field guide that allows the user to see and compare many images of an animal that you are investigating. This makes identification or observation of a behavior much easier. In order to experience beyond the capabilities of a book and take full advantage of this app, an annual subscription will be necessary. This will allow the user to benefit from creating, using, and saving your Life Lists, communicating observations, and sharing notifications of observed marine life with others. This sharing of information greatly enriches the distribution of knowledge of our marine world. The annual subscription is $ 12 US dollars/year, ($1 dollar a month.) We have been able to present this application and subscription to you at such a low price because we are relying on your support. The subscribers will help us to continue to pay for the servers and the communication in the cloud. This will greatly help unite us in our common goal of preserving of the marine world.

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.
