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.

A new mobile "Fate RPG," presented by TYPE-MOON! With an impressive main scenario and multiple character quests, the game features millions of words of original story! Packed with content that both fans of the Fate franchise and newcomers will be able to enjoy. Summary 2017 A.D. Chaldea, an organization tasked with observing Earth's future, has confirmed that human history will be eliminated at 2019. Without warning, the promised future of 2017 disappeared. Why? How? Who? By what means? AD. 2004. A certain provincial town in Japan. For the first time ever, a region that could not be observed appeared. Assuming that this was the cause of humanity’s extinction, Chaldea carried out its sixth experiment - time travel into the past. A forbidden ceremony where they would convert humans into Spiritrons and send them back in time. By intervening in events, they would locate, identify, and destroy the space-time Singularities. The mission classification is an order to protect Humanity: Grand Order. This is the title for those who would take a stand against human history and battle fate in order to protect mankind. Game Introduction A command card battle RPG optimized for smart phones! Players become Masters and together with Heroic Spirits, defeat enemies and solve the mystery of human history's disappearance. It's up the players to form a party with their favorite Heroic Spirits - both new and old.

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.
