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 mobile-first design of the Zebra platform ensures that all solutions are intuitive and easy to use on any device. Store associates are empowered to work more efficiently, whether they are digital natives or not. Modernize your store solutions and keep associates engaged with customers in real time. Retailers want to keep their store leaders on the sales floor, helping customers and coaching associates. Thanks to its mobile-first design, the Zebra platform offers full functionality from wherever the manager is in the store; they can update labor schedules, assign tasks, and address real-time store execution challenges from a smart phone or tablet, instead of leaving the sales floor to check a computer. From a phone or tablet, users can: - Generate schedule or edit it as per real time requirements. - Update user details. - View leave requests.

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.

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.
