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.

SprinterLevel is a leveling app for Mercedes Sprinter-based vans and RVs. This app handles long and short Sprinter wheelbases, and it can also be customized for any RV. This app shows how much lower three tires on your van or RV are than the highest tire, the reference tire. These values can be used for re-parking or for choosing leveling block heights. Leveling biases can also be entered into the app, so you can make the sink drain work better or ensure your head is higher than your feet when sleeping. Sounds can be used to level your van with this app. You can set a level tolerance value and chose a sound pair. One sound will be played if you are out of the level tolerance range. Another sound will play if you are within the tolerance level. For example: You can choose a level tolerance of 2 inches. Then make sure the audible icon on the upper left of the main display is activated and put your phone on a flat surface. Get in the driver's seat and start moving your vehicle. The app will tell you when you are out of and within the 2 inch level tolerance limit. The SprinterLevel app also has a 'Gear Left Outside' GPS alarming feature. If you put stuff, or plan to put stuff, outside your van or RV ... you can use arm this alarm as a reminder in case you drive away and leave your leveling blocks, or generator, or mountain bike, etc. Once the alarm is armed, the app will run in the background. When the app sees that you have traveled past a selected alarm distance, it will play an audible alarm and send a local notification to the phone. Three distances are available for the GPS alarming "geo-fence". These distances allow you to arm the alarm and then walk around your campsite without setting the alarm off. SprinterLevel will quickly pay for itself it it means you don't drive away from your $1000 generator or a $2500 mountain bike! SprinterLevel is a standalone app. No connection to the Internet is needed.

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.
