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.

Our app offers a specific exercise for EVERY week after the birth of your baby.. all the way to 6 months postpartum! The Oh Baby! Fitness Mom & Baby Weekly Workout shares everything we've learned from training nearly 30,000 women in prenatal and postnatal fitness. Each week's video will target specific areas and help you strengthen and tone your post-baby body safely and effectively. Each exercise is designed to provide you with the most appropriate workout for your week of postpartum recovery using Pilates, Yoga and strength training exercises you can do at home with no additional equipment. We also show you how to incorporate your baby into the exercise! Short videos and descriptions will show you exactly how to do the exercise and will explain how the exercise will help you build muscle, flatten your tummy or relieve stress. String exercises together to make your own personalized, SAFE mom & baby workout. You can also track your workout each day, and note how you liked the exercise, if it was challenging, etc. Features: * Birthday Calculator - Enter your baby's birth date and immediately see an exercise that's best suited for your CURRENT week of postpartum recovery. You'll be able to view exercises for PAST and FUTURE weeks too. * Weekly Exercise Videos - Specific exercises with short videos for each week of postpartum recovery up to 6 MONTHS after the birth of your baby! Each exercise has three notations: 1) What it does (the muscle group the exercise focuses on) 2) What to watch for (specific modifications for exercise) 3) Number of times (reps) you should do of the exercise * Tracker: A special "tracker" feature shows you how many times you've done an exercise, on what date, and any notes you make about it. * Favorites: You can mark and keep track of your favorite exercises. * Resources: We supply links to valuable resources, blogs, videos and more. The American Congress of Obstetrics and Gynecology recommends pregnant women work out for 30 minutes on most if not ALL days of the week.

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.
