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 game focused on delivering a pure Sudoku experience, dedicated to bringing players undisturbed and highly flexible puzzle-solving fun: Clean & Ad-Free: No pop-up ads or embedded ads throughout the game. Say goodbye to interruptions and immerse yourself in Sudoku solving, focusing fully on the thrill of logical reasoning. Unlimited Tools: Practical tools like hints, note-taking, and error marking have no limits on usage, levels, or paywalls. Use them as needed to easily tackle Sudoku challenges of all difficulty levels. Multiple Game Modes to Choose From: A variety of Sudoku types are built-in to suit different players' preferences: Classic Sudoku: Follows the basic rule of "no repeated numbers in each row, column, or 3x3 box"—the top choice for Sudoku lovers to start and advance; Diagonal Sudoku: Adds the requirement of "no repeated numbers on the two main diagonals" to the classic rules. The difficulty increases, testing your overall thinking more; Window Sudoku: The board is additionally divided into 4 "window areas," where numbers must also be unique. This further enhances the complexity of solving; Jigsaw Sudoku (Irregular Sudoku): The 3x3 boxes are no longer standard squares but irregular shapes. It breaks fixed thinking and offers more flexible gameplay; Killer Sudoku: Areas are divided by dashed boxes, and the sum of numbers in each box must equal the value marked inside. Combining calculation and logic, it’s highly challenging; KenKen (Calcudoku): Combines number operations with Sudoku rules. Solve puzzles by meeting the operation result requirements of rows and columns, offering both fun and logic. We will continue to update the game in the future, constantly adding more innovative Sudoku modes to keep your Sudoku experience fresh. Anytime, anywhere, start a brain-teasing yet stress-relieving logical journey!

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.
