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.

Download this app for success in calling coyotes, foxes, bobcats, wolves, and other predators as well as squirrels, sandhill cranes and javelina in. Field proven. Unlike other predator calling apps on the market, this one was designed with you, the hunter in mind. Everything is on one screen. When you're out in cold weather, the last thing you want to be doing is navigating through many screens to get to the sounds and controls. This app solves that problem. When you start this app up, it's ready to go. The sounds on this calling app have brought much success to those who've used it through the years. This is the only predator calling app you'll ever need for bringing in and locating coyotes, foxes, bobcats, mountain lions, lynx, bears and much more. You can play multiple sounds together at the same time, and it can also loop individual sounds so they play non-stop. Sounds will keep playing when your device goes into sleep mode, is locked, or when you minimize the app. You can use your own bluetooth or wireless speaker/amplifier by connecting it to the headphone jack for added volume to aid in long-distance calling. This will be especially useful when crow hunting as you want to be able to broadcast your sounds to much further distances to bring them in to you. Includes the following 18 sounds: Coyotes Howling Coyote Siren Locator Fox Mating Call Mountain Lion Growls Squirrel Distress Squirrel Mating Call Frenzied Crows Sandhill Crane Javelina Baby Rabbit Distress 1 Baby Rabbit Distress 2 Baby Rabbit Distress 3 Cottontail Distress Jackrabbit Distress Sparrow Distress Mockingbird Distress Robin Distress Rodent Distress

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.
