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.

TRAACKMAN-VERIFIED PHYSICS Our calculations are based on professional TrackMan research used by tour players worldwide: • Headwind: +1 yard per 1 mph per 150 yards • Tailwind: -0.5 yard per 1 mph per 150 yards • Crosswind drift calculated automatically • Temperature compensation for cold and warm conditions SHOT TYPE SELECTION Different shots react differently to wind: • Low (Knockdown): 30% less wind effect – perfect for controlling trajectory • Normal: Standard ball flight with full wind calculation • High: 30% more wind effect – important to know when hitting high approach shots WIND DIRECTION INDICATOR A simple arrow shows you the wind relative to your target. Instantly see if you're hitting into the wind, downwind, or dealing with a crosswind – and by how much. 4-DAY WIND FORECAST Planning your round?

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.
