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.

■ Overview When traveling to a tourist spot by JR or subway, the most confusing thing is choosing the exit at your arrival station. In Tokyo in particular, there are many stations that are served by multiple lines and have many exits. Even after leaving the station using the exit signs as a guide, you may still find yourself unsure of which direction to start walking. When heading to your destination, this app will guide you to the best exit and route for each station and line you will be using. It also uses location information to display the route from your current location to your destination, helping to make sightseeing more comfortable. ■ Function · Area Display All areas that have been stored will be displayed on a map of Tokyo and in a list. · Select an area Select the area you want to visit from the map or area list to display a list of spots and access stations around the area. · Route display from access station Select the line you wish to use from the lines displayed at each access station and tap the route display to be guided to the recommended station exit and route to the surrounding area. · Display route to spot When you tap the route display of a spot from the spot list, you will be guided to the recommended route from your current location to the spot. · Tagging Each spot can be tagged with seven different colors. · Other After selecting an area, a map will be displayed showing useful information in the area (public toilets, benches, smoking areas, police boxes). ■ Stored areas The areas stored in this app are as follows. · Imperial Palace Outer Great course for walking or running. · The East Gardens of the Imperial Palace Historic gardens, including the former site of Edo Castle. · Marunouchi A stylish street surrounded by skyscrapers. · Ginza Food tours, gift shopping, hidden alleys and bars. · Tsukiji Tsukiji Outer Market is home to around 400 stores. · Hama-rikyu Gardens The garden of the Tokugawa Shogunate. · Akihabara Popular stores such as anime and game goods specialty stores and maid cafes are listed. · Tokyo Tower Includes popular temples, shrines, and parks. · Tokyo Metropolitan Teien Art Museum The main building is in Art Deco style. · The National Art Center The huge curtain-like glass wall is an attractive feature. · Kanda Used Book Street Japan's largest used bookstore district. · Kanda Musical Instrument Stores An area where many music stores are concentrated. · Tokyo Metropolitan Government Building The observation deck on the 45th floor of the First Main Building is popular. · Shinjuku Gyoen National Garden The vast grounds are home to approximately 10,000 trees. · Meiji Jingu A space where visitors can forget the hustle and bustle of the city and relax their mind and body. · Meiji Jingu Gaien Ginkgo tree-lined street and surrounding spots. · Takeshita Street A street packed with shops aimed at young people, including trendy fashion brands. · Cat Street A back alley between Shibuya and Harajuku.

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.
