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.

LINES will help you save time and money during your Universal Orlando trip. Because we’re independent travel writers, we can tell you what Universal can’t, from actual waits in line, to which park will be less crowded every day of your trip. LINES features include: -Both Universal’s currently posted wait time at every attraction and how long you’ll REALLY wait in line, based on our experience and that of thousands of families on the same ride. -New “Ride Now” and “Wait to Ride” recommendations to show whether waits are going up or down at your favorite rides. -Customized step-by-step touring plans for both Universal Studios Florida and Islands of Adventure parks, including The Wizarding World of Harry Potter areas. You tell LINES which rides you want to see, and LINES will create a step-by-step itinerary showing when to go to each ride to avoid long lines. You can even change your plans while you’re in the park! -A Crowd Calendar showing you how busy each park will be over the next ten days. -Universal’s official app doesn’t show you the waits for many attractions or character greetings. LINES has wait times for more rides, shows, and character greetings than even Universal’s own app. -Ask questions and get fast answers from our online community of 120,000 theme park experts. -Menus and prices for every restaurant, kiosk, food stand, and cart in all of Universal Orlando Resort – more than 4,500 things to eat! Every menu is searchable – you can find every steak in Islands of Adventure or throughout the parks, CityWalk, and the official Universal Orlando Resort Hotels! Our theme park trip planning tools have been featured in USA Today, the New York Times, FOX News and dozens of other newspapers, magazines, television and radio shows. Since 1986, we’ve helped more than 3 million families plan their vacations. Note: Some LINES features, such as the crowd calendar and wait times, require an in-app subscription purchase to access. Other LINES features, such as customized touring plans, menus, and viewing chat forums, are completely free. Your in-app subscription includes 365 days of access to TouringPlans.com, the Web’s most popular subscription-based site for theme park trip planning.

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.
