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
Flash Fire will help fire service students and trainees prepare for written examinations for Firefighter I and Firefighter II courses. The questions are primarily based on IFSTA Essentials 6th Edition. Our app includes a test bank referenced to the IFSTA Essentials 6th Ed textbook with over 2,200 questions. Each answer to the questions includes an IFSTA page reference and NFPA 1001 reference. This app allows you to take a comprehensive exam, study questions from a specific chapter of the book, or even build your own exam based on the chapters you wish to study. Our app allows you to favorite questions you would like to review, and will even save all questions you answered incorrectly on any test so you can go back and look at them again. Additionally, Flash Fire includes questions for both FF1 and FF2. As always, don’t hesitate to contact us if you have any questions or comments at: [email protected] Study hard and stay safe out there! Note: Flash Fire is not directly associated with IFSTA, however our content is designed to aid those studying Essentials of Firefighting material.

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.
