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
The award-winning On Cinema web series is the only movie review show on the Internet, and now it's the only movie review app on the market. Host Tim Heidecker, and Featured Resident Guest And Film Expert Gregg Turkington share their expertise as they offer up-to-date, reliable opinions on the latest and greatest movie releases. Audio reviews for over 17,000 films are included in this easy-to-use, fun, pocket-sized movie review database. Each film is discussed and then given a rating from zero (BOMB) to five (CLASSIC!) bags of popcorn. You will no longer have to navigate the murky world of film criticism on your own! Type in nearly any title, and Tim and Gregg have an opinion on it. They don't always agree--but you'll agree that the On Cinema app is the newest, hottest way to access movie reviews. Tired of wandering the aisles at your local video rental shop, unable to decide on a movie? Our randomizing "quick pick" feature can steer you in the right direction. Tim and Gregg have combined their decades of movie-viewing experience into a fun app that is the life of any party, and a distraction at the workplace.

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.
