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
This is the complete Athletics Rule Book Edition 2024, with an index that was created to better organise the specific information that you re looking for. Im an Athletics Official and I carry my rule book all the time and it gets wet and damaged. With this app, you can read, view, search and easily find the information without having to have the rule book with you. I ve created this app from the necessity of having to check the rules all the time. And having all this info in an app, makes it faster and more efficient. The pdf used in this app is property of World Athletics. World Athletics gave me the permission to use their pdf document and put it in this app. Exactly the same way as they did with my previous app for Edition 2022. I m using their pdf downloaded from the WA website and created the index for this app. World Athletics gave me permission to use their pdf document and add it to this app. The pdf alone can be downloaded for free from their webpage. This pdf is a searchable pdf. In the section "Complete Rule Book" you ll be able to search for words if needed The index has been created following the structure of the rule book

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.

BUILD KIT DIFFICULTY
Intermediate
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.
