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
Photo fun recipe: just add eyes. Googly eyes! * Choose any photo (or take a photo) and the app will automatically add googly eyes to it. If the app recognizes faces in your photo, it will place googly eyes over every eye it detects. On the iPhone, you can also add as many eyes as you want by long pressing on the logo - on the top bar - and then tapping "Add eyes". On the iPad, tap on the eye button on the top bar. * Move the googly eyes with your finger wherever you want. * Change the size, color and position of the eye and the iris by tapping on the googly eye, and then using the presented options to make the changes. * Copy an image from another app and paste it into this one. To copy an image from Safari for example, long press the image, choose copy from the menu. To paste it into this app: - On the iPhone, long press the logo and choose "Paste an image" from the menu. - On the iPad tap the paste button on the top left logo bar * Open a photo directly from Safari: - long press the photo - tap "Share" to share it with the Googly Eyes app - in the Share menu, scroll to "Add Googly Eyes" and tap on it * Added too many eyes to the photo? Delete a googly eye by tapping on it, then tap on the "Delete eye" button. * Cross eyed or wide eyed? To make all future eyes have the same iris position, tap on the googly eye, then tap on "Save iris position"

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.
