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
SEAiq Pilot is designed especially for use by river, channel, and harbor pilots. It includes support for charts in the S-57, S-63, iENC and BSB/KAP formats and use of external NMEA/AIS over WiFi. IMPORTANT: For non-pilots, we recommend SEAiq and SEAiq USA. This app is free to download. All features are available during a 7-day evaluation period. An in-app purchase is required to permanently upgrade the app, otherwise after the evaluation period only basic chart viewing is supported. SEAiq Pilot and SEAiq Pilot VPP are the exact same app and differ only in how they are purchased. Features unique to SEAiq Pilot include: * Support for official HO S-57/S-63 marine charts * Adheres to IHO S-52 chart display standards * Predicted vessel display (with ROT) * Docking aids displaying distance/velocity to wharf fenders * Vessel catalog * Supports WiFi based AIS plugs and Portable Pilot Units * NMEA/AIS record and playback * Waypoints, routes, ETA, XTD, speed limits * Route Meeting Point * Visual CPA * AIS "virtual boarding" * Mariners tools: VRM, EBL, Mariners Notes, Clearing Lines Continued use of GPS running in the background can dramatically decrease battery life.

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

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.
