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
Key Features: Find Nearby ERs: Locate emergency rooms, urgent care centers, and hospitals based on your GPS location. Real-Time Wait Tracking: View live ER wait times, crowd levels, and recent updates powered by AI prediction models. Medical History Access: Log and review previous visits, diagnoses, and ongoing conditions securely. AI-Driven Insights: Analyze patterns from previous visits to estimate future wait times and identify less crowded facilities. Multi-Source Data: Integrated with Google Maps and TomTom APIs for precise, up-to-date hospital data. Secure & Private: All health and location data are encrypted and used only for improving your experience. Note ! This applicationis designed to assist users in locating nearby emergency rooms and viewing publicly available or user-contributed wait time information. It does not provide medical advice, diagnosis, or treatment and should not be used as a substitute for professional healthcare judgment. Always call 911 or your local emergency number in case of a life-threatening emergency. The accuracy of wait times and hospital availability is dependent on third-party data sources, including Google Maps, TomTom, and user submissions. We do not guarantee real-time accuracy or assume responsibility for any delays, errors, or omissions in the data presented.

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.
