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
* With the KX2 Micro Manual on your iPhone or iPad you will have a comprehensive reference to operation of the KX2 with you wherever you choose to operate from in the field or at home. It's like having the Elecraft KX2 Owner's Manual in your pocket. * Tapping on any of the page number links provided in the KX2 Micro Manual will instantly take you to the referenced page number. No more leafing through paper manuals or scrolling up and down in PDF files. * Look in the Index for common terms used in the manual and tap on any index item to be redirected to that item in the text. * The application includes all Firmware Release Notes documented since revision A7 of the KX2 Owner's Manual was published December 18, 2017. * The app is a universal app which means it runs on any size iPhone or iPad.

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.
