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.

You just blow your mind to tap, swipe or hold the finger on top of a series of tiles at the appropriate time, matching the beat or sound effects happening in the song. Let’s try and become a master! GAME OVERVIEW - SuperStar’s gameplay will feel familiar to anyone that has played rhythm games before. - The mastery layer of the game is entirely based on dexterity. Improving reflexes and muscle memory, mastering the song patterns and timings, and learning appropriate finger techniques to get a bit more score. - Each track completed in the game generates a score that is rated from one to five stars. When the player achieves the maximum star rating, silver, gold and diamond medals appear. The best scores in songs guarantee new tracks for your repertoire. HOW TO HIT ALL TILES ON "PERFECT+" - “Perfect+” occurs when the player plays the tile exactly at the moment the beat overlaps the perfect zone on the screen. - If you are a little early or late, the grade is just recorded as perfect. Even if the multiplier continues through a streak of perfect beats, without “Perfect+” on every note, the diamond medal won’t be yours. FUN & CHALLENGING GAME “It’s not that easy playing this game. I love the challenge every time.” “Love this game. I’m competitive and this game feeds the soul.” “Entertaining and challenging. Definitely holds my attention for a while! Love it” We hope you will enjoy SuperStar when play great international music hits with the touch of your fingers. Join and challenge how far you can go in SuperStar?

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.
