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
RxHero is an educational game for healthcare students and professionals to learn the top 250 medications in the outpatient setting (also known as the Top 200 Drugs or Top 300 Drugs). RxHero uses a multi-modal, adaptive learning approach with quizzes, matching, and drug spelling combined with a gamification component with quests, campaigns, points, and rankings as you progress through the app. This app is perfect for pharmacists, pharmacy technicians, physician assistants, nurses, nursing students, physicians, medical students, and other healthcare professionals. The drug database is designed to aid in studying for both students in school and those preparing for standardized exams (eg, NAPLEX, BCPS, PTCB, ExCPT, PANCE/PANRE, NCLEX, USMLE, COMLEX). == FEATURES == • Content includes brand/generic names, drug class, indications, common/rare adverse effects, boxed warnings, counseling pearls, notable drug interactions, and mechanism of action • Assess your drug therapy knowledge using multiple-choice quizzes, term matching, and drug name spelling • Adaptive (Leitner) learning mode focuses on drug facts that you haven't mastered yet to optimize your study time • On-demand drug pronunciations are embedded throughout the app • Contains the top 250 of the most common outpatient medications based on the ClinCalc DrugStats database (version 19.1) == GAMIFICATION == • Motivate your learning with a unique "gamification" component • Earn points for answering correctly and bonus points for rapid responses • Earn higher rankings as you accumulate points • 5-star system denotes your proficiency with each drug category • Earn a variety of awards as you reach important game milestones in the app == AUTHOR INFORMATION == This app and all of its content was created by Sean P. Kane, PharmD, BCPS – a clinical pharmacist, associate professor, and author of the popular evidence-based website, ClinCalc.com. The drug list and drug information closely mirrors the popular video-based course series The Top 250 Drugs (http://top250drugs.com).

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.

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.
