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.

Save a trip to the lumber store by planning your project with precision. KerfMaker makes sure you get just enough wood for your woodworking project. Designed by a woodworker, KerfMaker has the tools you need to help keep your lumber costs low and your project together. With KerfMaker's project planner, you'll assemble a precise list of boards needed to get your project done – and make sure you only need to make one trip to the lumber yard or hardware store. “...easy to learn, very useful. Sorts my parts quickly. Worth the purchase!” - Esther85839350, App Store Review "Though this has potential in the shop, it’s in project planning and shopping where this [app] on a mobile device really could shine.” - Tim C., Popular Woodworking author ORGANIZE AND PLAN Pick your boards, plan your cuts and put it all in one place. Use the parts list to keep track of everything you need to assemble. Organize your projects with photos, and share existing projects with other woodworkers. SAVE MONEY ON SUPPLIES We’ll help make sure you’re buying exactly the wood you need to finish your project, so you’ll have less waste — and more money to put toward your next perfectly crafted project.

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.
