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
HamWaves Sidekick is an indispensable app for all amateur radio operators. We never seem to have access to user manuals when we need them. Even when we do, programming instructions are sometimes hard to understand. HamWaves Sidekick was written to solve this problem. Using a clean, gesture enabled interface, it provides clear, easy to follow step-by-step instructions to explain basic programming for dozens of popular handheld and mobile radios. Programming instructions are always available for offline use. It is extremely helpful for ARES and RACES groups that may need to add frequencies to a wide variety of radios on the fly. The app also provides one button access to the user manual for each radio. It will automatically download if it hasn't already been downloaded before. You can download only those manuals you are interested in or download them all. Once the manual is downloaded it will be available for offline use. The app covers dozens of popular handheld and mobile radios as well a few popular scanners. Included, are instructions for radios from Yaesu, Kenwood, Icom, Alinco, Anytone, Wouxun, Baofeng, BTECH, Quangdheng, TYT, TIDRadio, Radioddity and more. The app also includes helpful reference information such as frequency allocations, CTCSS/DCS tabes, Allstar commands, APRS reference for APRS capable radios, Packet radio commands, and much more. Links to user manuals are carefully researched to always provide the best quality manuals available for public distribution. Users are encouraged to visit our website and let us know of other radios they would like to see included in the app. We'll be happy to add them! Family Sharing is supported. Dark mode is supported.

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.
