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.

Wheel Fit Pro makes wheel and tire fitment easier to understand before you buy. Compare your current setup to a new one and quickly see how changes in wheel width, offset, backspacing, tire width, and overall diameter affect inner clearance, outer poke, and stance. Designed for truck, SUV, off-road, and performance enthusiasts, Wheel Fit Pro gives you a clean visual way to compare stock and aftermarket setups without digging through forums or trying to do all the math in your head. Features: • Compare current and proposed wheel and tire setups • See changes in inner clearance and outer position • Understand how offset and backspacing affect fitment • Compare tire diameter, width, and sidewall differences • Use front axle style visuals to understand suspension side vs fender side • View setup changes in a simple, modern interface Wheel Fit Pro is useful for: • Comparing stock wheels to aftermarket wheels • Planning larger tires for trucks and SUVs • Checking how far a setup may move inward or outward • Estimating a more flush or more aggressive stance • Making more informed wheel and tire buying decisions Whether you want a cleaner daily driver setup, a wider stance, or a more aggressive off-road look, Wheel Fit Pro helps you compare the numbers in a way that is fast and easy to understand. Important: Wheel Fit Pro is a comparison and visualization tool. Actual clearance may vary based on suspension design, alignment, ride height, tire brand, tread pattern, wheel design, brake package, spacers, and other vehicle-specific factors. Always verify final fitment on your specific vehicle before purchasing or installing parts. Wheel Fit Pro helps you spend less time guessing and more time choosing the right setup.

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.
