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 an application designed specifically for Muskie fishing, to maximize the experience for any angler from beginner to expert. The application contains a selection engine that runs through a sequence of conditions, calculates based upon specific algorithms, and sends a detailed response. This result will give anglers moreskie fishing, and tips/techniques to help find and catch more fish. There is also an equipment section focused on suggested lures and tackle for going after big Muskies. There is also a fish log to record your biggest catch while out in the wide open waters, with options for length, weight, where caught, what lure was used and more. Muskie Fishing is the ultimate application for helping anglers find and catch more Muskie. If you're a beginner, this can put a fish in your boat fast. If you're a seasoned Muskie angler, you can use the app to narrow down your location and baits for a day on the water, and maybe find a few tips to catch more and bigger fish. The interface is user friendly and designed as a quick utility and reference. Enjoy and fish hard! This application is dual designed and maximized for the new iOS 7 operating system and pre-iOS 7 systems. See the screenshots for examples. Thank you.

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.
