Generating… usually about a minute.
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.

AirTrack is an application designed to integrate with flight simulators in real time over a local area network, providing remote flight display and control through glass cockpit instruments, as well as control over some of the simulation variables. It replicates instruments and panels found on real planes using devices such as tablets and computers. With the aid of a plugin in the simulator, flight data is exchanged over the local network and displayed on the Mac, iPad and iPhone apps. Likewise actions on these are propagated back to the simulator and allow for its remote control. But if this isn't enough, AirTrack can also use your device's built-in GPS, Accelerometer and Gyro to determine your current movements and attitude and the Internet to download real weather to simulate an aircraft's sensors. Turn your car trip into a flight experience by getting information about your instant position, heading and surrounding waypoints. See yourself in an EFIS style navigation display / primary flight display or plan your multi-leg trip with the built in flight planner which gives you real-time information about your waypoints, how far they are and how long it will take you to reach them. For a comprehensive summary overview visit the app pages at: https://haversine.com/airtrack For a detailed in depth description of how things work, check its operations manual at: https://haversine.com/airtrack/operations In its present version AirTrack supports both the X-Plane (10, 11, 12, …) for which it was originally developed, and the Microsoft Flight Simulator 2020. Plugins currently exist for X-Plane and MSFS2020. In the future AirTrack may and will quite possibly support other simulators and flight data sources as it has been designed with horizontal expansion in mind.

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.
