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.

"I can ensure you, if you’re a professional at the highest level or an amateur golfer, you are very much behind if you don’t have the app or their charts. It’s the best wind tool and calculations in the world directly in your phone.” - Edoardo Molinari "Fantastic app." - Golf Digest, USA Welcome to the original Tour Wind Golf app, developed by the professional golfer Marcus Svensson. We are striving to be the worlds best data-driven system to help competitive golfers calculate how wind and other environmental factors affects golf shots, directly in your phone. Currently active in more than 35 countries and trusted on a weekly basis by numerous players on PGA-Tour, amateurs on all levels and professional caddies worldwide. Official training app and partner to the Swedish National Golf Team. This is how it works: 1. Simply aim your phone towards your intended target line. 2. Type in how far away you are from the target (supports meters and yards) and choose your intended ball fight. 3. See instantly exactly where the wind comes from and how much it will affect your shot in real-time. Our app connects in real time to world-leading weather services and calculates how the ball will be affected by wind, temperature, and elevation. All calculations are based on extensive ball-monitor testing, ensuring high accuracy and reliability. The accuracy of our app has been independently tested on multiple occasions and is recommended by Ryder Cup caddies. More features: - Upcoming wind forecast for the next 5 hours. - 4-Day wind forecast at the exact same spot – perfect for checking tee boxes during practice rounds and seeing how conditions may play out on tournament days. - You can manually adjust wind direction, windspeed, temperature and sea height level to simulate different conditions and see the effect on the ball. - Wind direction includes a compass view for better orientation. - Unit switching: choose between meters/kmh/°C or yards/mph/°F. Supports all measurement units and seamlessly switch to your own preference. - See all the metrics with windspeed, gust, wind direction, head/tail, cross and altitude. - Now also works with Apple Watch as we have released a beta. As we usually say, we don't like guessing.

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.
