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
• learning sql syntax on specific queries and commands examples: - how to combine multiple tables in a single query? - how to sort the result of grouping data? - what types of data are there in sql server? these and over 150 of other code samples for sql are available in the application. • the best examples of codes from books and specific internet resources are selected in the program. finding the best decision on the internet may demand hours of working time. ready for use and tested code "recipes" are included in the application. • one app for ios and macos. buy once and use on your phone, tablet or computer. • the application is a good tool during the exam or the preparation to the interview because it contains answers to frequently asked programming questions. • all examples in the application are available offline. the application can be used when the internet connection is not available. • quick search of the correct example by the code or by the name of topic. • being a developer, i use this program when i need to remember quickly how to solve a given task in sql language.

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.
