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
Media Catalog is created to help you keep a catalog of your collection of movies, game, music, etc. The catalog will be grouped based on the catalog type and genre. You have the option to print (single copy, multiple copies, or page range), post on Facebook, display pdf file, SMS or email to your friends. There are four functions available: Manage Catalog Types - Enter the catalog types (e.g. movies, games, music), description and photo. You can select the catalog type photo from your photo album, delete selected photo or take a new photo. To search for a catalog type, simply enter the name and the description and photo will be shown. You can then change the description or photo if you wish. You can also delete unwanted catalog types. Deleting a catalog type will also delete all items and genres under that catalog type. Manage Genres - Enter the genre (e.g. drama, horror, etc.), description and photo. You can choose the genre photo from your photo album, delete selected photo, or take a new photo. To search for a genre, simply enter the genre name and the genre details will be displayed. You will also be able to change the description and the photo. You can also delete unwanted genres. Deleting a genre will delete all items under that genre. Manage Items - Details entered include name, description, location, medium, release date, rating, no. of discs, runtime, region code, language, photo and favourite. You can choose the photo from your photo album or take a new one. To search for the item, simply enter the name and the details will be displayed. You then have the option to change any of the details and the photo. Display Catalog - There are two functions. You can display a chosen item in the catalog. You can either print the item details to an iphone compatible printer, display the PDF file, SMS the item details, post on Facebook or email the item. A pdf file of the item will be attached to the email and a copy of the item details will be displayed in the email body. The Facebook post will include the item details and a photo. The second function allows you to email, display PDF or print all items in a genre or only your favourite items. The pdf file can also be sent to WhatsApp, Messenger, iBooks, Yahoo Mail, Evernote, Notes, Viber, iCloud Drive, etc. There is also a 'Help' button to guide you in using this app.

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.
