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.

"Colorever: relax with sparkling gems and beautiful coloring art. Every gem belongs somewhere. Tap a gem and watch the whole cluster glide home, one by one, until a bright gem art picture is complete. Easy for everyone, fun for all ages. No timers. No fail screens. No game over. Just you, the gems, and a calm little puzzle you can always solve. WHY PLAYERS STAY See the whole picture from the start. Nothing is hidden, nothing is guesswork. You always know where every gem is going, so the pleasure comes from planning the route, not from hunting for a secret. Colorever is a puzzle funny game you can play with your shoulders down. HOW TO PLAY Tap a gem, move a cluster. Tap one gem and every connected gem of the same color is picked up together, then flies to its matching space one gem at a time. Read the board. Each space on the board already shows the color of the gem it is waiting for. Match gem to space and it locks into place with a satisfying click. Use the tray. The tray holds gems you are not ready to place yet. Park a few, open up the board, then bring them back in when the space is free. Finish the picture. Place the last gem and the full gem art scene lights up, ready for your gallery. A GROWING GEM GALLERY Hundreds of pixel art pictures to complete, from animals and food to flowers, cities and cozy little scenes, with fresh sets added regularly. Every picture you finish is saved to your gallery, so your collection of gems and gem art keeps growing as you play. FEATURES Relaxing by design. No countdown, no losing streak, no pressure. Play one puzzle on a coffee break or twenty in a row. Always solvable. Every level has a solution, so getting stuck is temporary, never fatal. Gentle learning curve. The first gem puzzles teach themselves. Later boards are wide, layered and genuinely worth thinking about. Handy helpers. Add an extra tray space, undo a move, take a hint, or let a smart tap tidy up the easy gems for you. Made to feel good. Crisp gems, glowing diamonds, soft sound and light haptics on every placement. Play offline, anywhere. No connection needed. Pause mid puzzle and pick it up hours later, exactly where you left it. For everyone. Simple enough for a first ever puzzle game, deep enough for players who like to plan three moves ahead. FOR PLAYERS WHO LIKE Relaxing puzzle games. Gem art and coloring pixel pictures. Gem, jewel and diamond puzzles. Calm brain games and quiet logic. Satisfying, oddly soothing placement games. Take a breath. Tap a gem. Let the gem art shine."

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.
