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
Using just your iPhone/iPad camera, magically perform a real-life 3D X-Ray scan of anyone in real-time, from any angle! See skeletal bones & muscles, the beating heart, blood pumping veins, breathing lungs, nervous system, body organs & more. Stop imagining what it's like to see inside somebody & just try it! Walk around, scan up close, around the person, walk back, pan down their body, around their head. Scan full 360 degrees, any angle, any body part. You won’t believe what you see, and neither will they when you show it to them. It’s Amazing! Choose from X-ray scanning modes: "Classic" blue X-Ray vision, "X-Ray Film," "Heat Vision," "Night Vision," & "Ultra Violet." Camera flash is also available for more realistic X-Rays. A giant leap closer to the impossible with the biggest breakthrough in non-medical 3D X-Ray scanning technology in App Store history. Using incredible Augmented Reality technology ("AR," mixing the real world with a virtual one), this is the most advanced and Amazing X-Ray scanning machine ever invented. From the makers of Amazing X-Ray FX (with over 10 MILLION downloads) comes the next-GENERATION in X-Ray FX, and it’s totally UNREAL! WATCH THE PREVIEW VIDEO TO SEE THE ACTUAL APP IN ACTION: Full-body live X-Ray scanning any part of the body in real-time. Record & share the simulated X-Ray scan as a video or photo for pure entertainment on Facebook, YouTube, etc., and blow your friends' & family's skeptical minds. NOTE: Not for medical use, this app is purely for showing off to friends how entertaining the ULTIMATE Amazing X-Ray FX can be.

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.
