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
This app provides, using temperature, altitude, humidity, atmospheric pressure and oil-mix ratio, a recommendation about the jetting configuration to use for KTM 2-strokes MX and enduro bikes (SX, SXS, EXC, XC and MXC models), from 2005 up to the 2027 minicycles. Every recommendation starts from the reference setup for that model and model year, and is corrected by the air density of your conditions. It is not a rule of thumb from a forum: it is a starting point worked out for the day in front of you. In order to get the weather values, the application can use the location service (GPS or WiFi) to obtain the position and altitude, and the network connection to get the temperature, pressure and humidity from the nearest weather station. Nevertheless, the application can run without GPS, WiFi and internet connection, in this case, the user has to give the weather data. What you get: - Main jet, needle type and clip, pilot jet and air screw, calculated from the air density for your conditions. - Weather from the nearest station in one tap, or typed in by hand when there is no coverage. - A logbook of your rides: what the app recommended, what you actually fitted, and how it ran, rated separately for the low, mid and high circuits. Export as CSV or move it to another phone. - Fine tuning to adapt the recommendation to your own engine. - Air density and density altitude, always on screen. The app lets you use different measure units: ºC and ºF for temperatures, meters and feet for altitude, mb, hPa, mmHg and inHg for pressures, and kg/m³, lb/ft³ and lb/gal (US) for air density. No ads, no tracking, no account. Every calculation runs on your device, so the app works at the track with no coverage: you only need a connection if you want to pull the weather from the nearest station. Valid for the following models from 2005 to 2027: - 50 SX: 2005-2027. - 50 SX Factory Edition: 2021-2026. - 50 SX Mini: 2017-2023. - 65 SX: 2009-2027. - 85 SX: 2005-2027. - 105 SX: 2006-2012. - 125 SX: 2005-2022. - 125 SXS: 2005-2007. - 125 EXC: 2005-2016. - 125 XC: 2017-2018, 2021-2022. - 125 XC-W: 2017. - 144 SX: 2007-2008. - 150 SX: 2009-2022. - 150 XC: 2017-2019. - 150 XC-W: 2017. - 150 XC USA: 2010, 2012-2014. - 200 EXC: 2005-2016. - 200 XC: 2005-2012. - 250 SX: 2005-2022. - 250 SXS: 2005-2007. - 250 XC: 2007-2009, 2011-2019. - 250 XC-W: 2017. - 250 EXC: 2005-2018. - 300 EXC: 2005-2018. - 300 XC: 2009-2018. - 300 XC-W: 2017. - 300 MXC: 2005. * Please note that the application is valid only for engines that use a carburetor. Not valid for fuel injection engines.

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.
