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
want to monitor morse code transmissions, without using a bulky computer? morse pad lets you decode morse code on your ipad, iphone, or ipod touch. just set your device near a radio, tune in a morse code transmission, and watch the decoded text. enter in the morse code speed in wpm. or you can turn on auto wpm mode, and morse pad will try to determine the sending speed. note that it may take take a moment for the app to determine the speed, or to adjust to changes in speed. you also need to enter the center frequency of the morse code audio, in hz. morse pad has an afc (automatic frequency control) option, it will automatically track frequency changes and lock on to the strongest signal found. the spectrum display in the upper left corner shows the audio spectrum, with a red line drawn over the center frequency. this can be used as a tuning aid. buy your copy of morse pad right now, and start decoding and displaying morse code transmissions in minutes.

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.
