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.

A bear safety app for your phone, alerts bears of your presence. Increase your safety when traveling in bear country. This phone app helps you be heard by bears, so you don't make the mistake of surprising them. HeyBear! works well with Bluetooth external speakers, like the ION Clipster Active. “Hey bear! Here we come! Hey bear!” My wife, friends and I have been calling out these words for decades while hiking in bear country in Alaska. As the bear safety saying goes: “Make noise when traveling in bear country”. Sudden encounters with bears, that’ don’t hear you coming, can be dangerous. The HeyBear! phone app helps alert bears of your presence. The app can be used with the phone’s speaker or paired with a Bluetooth external speaker for more volume and better phone battery life. The ION Clipster Active is such an external speaker that works well with the HeyBear! phone app. HeyBear! provides a number of progressively assertive voices and sounds: bear bells, female voice, male voice, whistle, alarm and siren. There are four audio clips for each of these sound categories and they can be played sequentially or randomly. Multiple categories can be selected, so you can customize a variety of sounds. Of course, you can make your own noise when traveling in bear country. But by pairing your voice with this phone app, it will sound to a bear like more people are approaching. This will increase the safety factor. Plus, if travelers are unfamiliar with what sounds to make when in bear country, this app can do the job for them. My companions and I have seen many bears over the decades of recreating in the backcountry of Alaska. But we have never had a bear charge us. Most likely this is because we have let the bears hear us before they see us. Hopefully the HeyBear! phone app can help make travel in bear country safer for you.

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.
