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
Have you ever experienced a strange moment that you simply couldn't explain? GhostBuddy is an entertainment app inspired by paranormal investigation, designed to bring excitement, mystery, and suspense to every exploration. Whether you're visiting abandoned buildings, exploring dark rooms, checking out legendary haunted locations, or simply looking for a thrilling experience, GhostBuddy creates an atmosphere of paranormal discovery where every scan feels like a step into the unknown. HOW IT WORKS GhostBuddy uses your iPhone’s built-in magnetometer, microphone, ambient light sensor, and camera to scan the surrounding environment in real time. Based on magnetic field activity, sound variations, light fluctuations, and camera input, the app generates dynamic paranormal-style readings and presents them through live radar displays, ghost alerts, mysterious visual effects, and immersive scanning experiences. Combined with real-time scanning interfaces and supernatural-themed interactions, GhostBuddy turns every investigation into a fun and engaging paranormal adventure. DISCLAIMER GhostBuddy is an entertainment app designed to provide a simulated paranormal investigation experience. It is not a scientific detection tool, professional measuring instrument, supernatural verification system, or occult/divination service. Any readings, alerts, scan results, visual effects, or other content generated by the app are intended solely for entertainment purposes and should not be interpreted as factual, accurate, scientific, or evidence of paranormal activity. We are not responsible for any use, misuse, or interpretation of the app or its results.

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.
