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
Help prepare yourself for New York State's Earth and Space Science Regents exam with this application. You can use it to quiz yourself with 10 question quizzes that draw from over 250 multiple-choice questions from past Regents exams. It also includes the most recent Earth and Space Science Reference Tables in an easy to use viewer where you can zoom into the page even on an iphone! The program also includes a set of flash cards for 500 vocabulary words. These words were carefully selected to reflect words from the New York State science standards and words that regularly show up on the Earth and Space Science Regents exams. Great effort was taken to write definitions for the words that were simple, to the point, and reflected the specific earth science meaning of the words. This is my first application for the iPhone and iPad. If you have any questions, feature requests, or comments, please contact me. I hope this helps you review for the exam and good luck on your exam day!

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.
