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.

Simply scan or enter a car’s VIN barcode and the app decodes the VIN and instantly generates a free comprehensive report with up to 200 data points. Our mission is to help the consumer get better educated and informed about a used car before buying it. We know buying a used car is an arduous and frustrating experience (we know as we've been through it many times). We believe having the right information and data helps make the process a bit less difficult and helps you get a better price and make a more informed decision. Each VIN check of a used car is Powered by iSeeCars.com's renowned data analysis engine which has been featured in many major publications and media outlets such as Consumer Reports, New York Times, Wall Street Journal, ABC/CBS/NBC News, CNBC, Forbes, Fortune, and many others. Each used car VIN report and lookup includes up to 200 data points such as: *** Market Value and Charts Get an estimate of the used car’s market value compared to other cars that have been sold in the same local area. *** Listing and Price History See a history of where and when the used car had been sold along with the prices and how long the car was on the market. *** Vehicle History, Open Recalls, Stolen Car Check, and More See how much the car was driven compared to the average car. Instantly check the vehicle history report (free in some cases) from Carfax or Autocheck, check for open recalls, see if the car had been stolen previously and look up other key things before buying or selling a used car. *** Projected Depreciation Get an estimate of how much the used car will depreciate over 1, 2 and 3 years and in comparison with similar and competitor cars. *** Best Time to Buy (and Sell) As with houses, cars also exhibit seasonal fluctuations. See when you should buy or sell to get the best prices. *** VIN Decoder / VIN Lookup Through the app, easily use your phone’s camera as a scanner and scan the VIN barcode of a used car and our app's built-in VIN Decoder look ups if it is a legitimate VIN (of a vehicle model year 1981 and newer - that’s the year when the U.S. government started standardizing VINs) and generates an instant report.

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.
