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
Resident Center, powered by Buildium, is designed with simplicity in mind. You can make payments, submit maintenance requests, contact your property manager, learn about your community, and more––with just a few taps. Features may vary depending on your property management company. Key features: - Never miss payment deadline again! With autopay you can set up recurring payments through your bank account or credit card. - Don't stress if you have an issue that needs to be fixed! Easily submit a request right from the app and include a photo so your property manager can get it resolved as soon as possible. - Stay informed about your building and unit. Your property manager can post announcements through the app to give you a heads up about things like parking bans, office hours, or even fun events in your neighborhood.

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.
