Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
OfferRight takes the guesswork out of making offers on rental properties. Enter your target rent, estimated repair costs, appraised value, and financing details — and OfferRight instantly calculates the maximum offer price you can make while still hitting your cash flow goals. Unlike basic mortgage calculators, OfferRight works backwards from your income target. It uses the lender's appraised value to set your loan amount, factors in repairs and closing fees directly into the offer price, and shows you exactly how much cash you need to close the deal. Key features: • Back-solves the right offer price from your target cash flow • ARV-based loan calculation — just like real lenders • Accounts for repairs, closing fees, vacancy, and property management • Shows conservative, target, and stretch offer ranges • Instant equity display at closing • Clean cash flow breakdown — every dollar accounted for Perfect for real estate investors and rental property buyers

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
