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
"It is most impressive when working with live video, as it does a good job of keeping up with changing action happening on screen" - TechCrunch.com Hue Camera creates an Ambilight-like effect using your Philips Hue lights and your device's built-in camera. The custom build algorithm of Hue Camera continuously analyses all individual pixels and takes hue, saturation, luminance, occurrence and many more factors into consideration to determine which specific colour is the most contributing to the overall ambiance. Your house will for example turn green when watching movies in the forest and turn blue for underwater scenes. Because Hue Camera uses the built-in camera, it's not limited to a specific device and can be used for content on televisions, Apple TV, gaming consoles, BluRay/DVD players and even things off-screen like photos and paintings. Although Hue Camera was designed to work within a wide range of situations, you can change the speed of colour transitions and the intensity of the colour to your liking.

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.
