What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Wake Watch is the Boater's Resource for information on no wake zones, boating speed limits and bridges. We have no wake zone and boating speed limit maps for FL, NC & CT. We have bridge heights and opening schedules for FL, GA, SC, NC, VA & CT. The app uses your GPS location to track your boat on the map to keep you aware of what bridges and no wake zones are coming up on your route. NOAA boating charts can also be used as the base map! This is a must have for recreational boaters in Florida and snowbirds cruising south for the winter down the ICW. Boating in FL can be frustrating due to no wake zones and limited bridge openings. Limited bridge openings could mean waits of up to an hour or more. This tool will help you to stay informed and plan accordingly. The app covers all of the waterways in Florida, including the Intracoastal Waterway (ICW), bays, inlets and canals. Also covers key areas such as the Okeechobee Waterway, New River, and more. Includes information from a variety of sources, including NOAA charts, state and federal Manatee Protection Zones, Boating Safety Zones and more. It covers the ICW all the way up to Chesapeake Bay, and all coastal waters and rivers up through VA. Tide station information was also added. For each tide station, the times for high and low tides each day are shown. Tidal heights are included as well. NOAA Coastal Waters Forecasts are now included. These include wave height forecasts up to five days out. NOAA Raster Nautical Charts can also be used as the background maps. Speed and heading data are now included. If your primary GPS/plotter fails, you've got NOAA Charts, speed and heading...Everything you need!

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
