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
Bloom is a private, guided breast self-exam tracker. Get to know what's normal for you and build a monthly habit that actually sticks. WHY BLOOM Many breast changes are first noticed by women themselves, not in a clinic. Doing a self-exam every month is how you learn what your normal feels like, so anything new stands out to you. Bloom makes that monthly check simple, guided and easy to keep up. WHO IT'S FOR Any woman who wants to take an active role in her breast health. Whether you're in your 20s starting your first habit, keeping notes on something you've been watching, or logging screenings alongside your doctor's care. FEATURES - Guided monthly check-ins. Walk through 12 signs of breast change, one at a time. - Photo tracking. Add optional photos each month to compare over time. - Compare. Put any two check-ins side by side, photos and notes included. - Screening records. Log mammograms, ultrasounds, MRIs and clinical exams, including the result exactly as your report states it. - Upcoming appointments. Track follow-ups and set recurring reminders. - Monthly reminders. Pick your day and time, and remind someone you love too. - Home screen widgets. See your countdown and your year at a glance. PRIVACY FIRST Bloom works completely offline. No accounts, no cloud, no servers, no data collection. Your records live on your device and nowhere else. Delete the app and everything goes with it. DISCLAIMER Bloom is not a medical device and does not diagnose, detect or screen for breast cancer. Always consult a qualified healthcare professional for medical advice.

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.
