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 new Dexcom Follow App is part of the Dexcom SHARE® system. Use this app if your loved one is sharing data from their Dexcom CGM app. The Sharer will need to send an invitation to allow you to connect after you have installed the Follow app. Dexcom Follow works seamlessly with your loved one’s Dexcom CGM, giving you visibility into their glucose data, even when they’re far away. Dexcom Follow allows you to view and follow their glucose levels, trends and data right from the app. Whether your child is in school, your parent lives independently, or your partner is traveling, Dexcom Follow helps you stay connected and informed. With Dexcom Follow, you can: • Remotely monitor your loved one’s glucose at a glance from your phone or Apple Watch† • Receive glucose information of up to 25 different Sharers – children, friends, or other loved ones – if you know multiple people with diabetes • Respond quickly with the help of customizable glucose alerts and push notifications that can inform you when a Sharer’s glucose levels are outside of target range

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.

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.
