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.

Sitting in a line of layout blinds in the middle of the field you and your buddies are anxiously awaiting a flock of Canada geese. You can hear them in the distance but are unable to see them yet. A few minutes later you see a flock of geese in the distance. You use this app to play the Canada goose sounds loud in hopes to get them to turn your direction. A few minutes later they are heading towards you and look like they are going to land in your decoy spready by your layout blinds. Moments pass as they start to drop lower and lower. Then you yell “KILL EM!!!” and you and your buddies unload. Several of geese fall from the sky in a frenzy of shotgun blasts. Once the smoke clears you and your fiends yell in excitement. What an amazing hunt! Did this moment happen by chance? Not this time because you created a perfect combination of goose calls from your phone that lured the flock of Canada geese to where you wanted them. Bagging geese without the right gear is almost impossible. It's important to have a shotgun, shells and decoy spread right for the job. Good hunters take everything they need to bag geese with them into the field. One of the most important tools for a successful hunt is a good goose call. No longer do you need drag along bulky electronic goose callers. With this Goose sounds and goose calls app you can simply select from a large selection of different goose sounds and play them with a Bluetooth speaker setup or connect your phone to amplified speakers. The sounds included are goose laydown calls, goose flock feeding, goose slow cluck, goose excited clucks, goose moans, goose honks, goose hiccups, goose murmur and excited goose sounds just to name a few. You can play the sounds individually and set them to repeat after the amount of seconds that you desire. Or you can manually tap different sounds create a deadly combination of calls that will work perfectly for goose hunting. So are you ready to stop leaving your goose hunting success to chance? If so download the Goose Magnet – Goose Calls app and get ready to have a goose hunt of a lifetime!

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.
