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.

Just open the app, see your distances, and pull the right club with confidence. — IMAGINE THIS You're standing in the fairway, 156 meters to the pin. There's a bunker guarding the front of the green. Can your 7-iron carry 150 meters to clear it? You open My Golf Distances and instantly see: 7 Iron - Carry: 145m | Total: 155m Decision made. You grab the 6-iron, swing smooth, and watch the ball land safely on the green. That's the confidence a yardage book gives you. — DEAD SIMPLE TO USE Setting up takes minutes: 1. Tap a club 2.

Ready when you need them. — FIND THE GAPS IN YOUR BAG Ever wonder if you have the right club setup? The gap analysis shows the distance between each club, helping you spot problems: • Too big a gap between 4-iron and 5-wood? Maybe add a hybrid. • Only 5 meters between PW and GW? Consider adjusting your wedges. See your entire bag laid out with gaps highlighted.

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.
