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.

A calm, offline cookbook for parents of babies and toddlers. OFFLINE-READY Porridge, snacks, and finger food recipes — every recipe works without an internet connection. No loading, no buffering, no "you're offline" banners. Open it in the kitchen, on a plane, anywhere. BUILT AROUND YOUR BABY Tell us your baby's birthday once and Baby Food shows recipes suited to their age stage. Add their allergens and every list automatically hides recipes that contain them. FIND DINNER IN SECONDS - Filter by age, allergens, cooking tools, prep time, difficulty, freezer-friendliness, and main ingredient - Search by recipe name or ingredient - Three clear categories: porridge, snacks, finger food TRUSTWORTHY BY DESIGN Every recipe's age and nutrition guidance is referenced to recognized health authorities — Taiwan HPA, the AAP, the UK NHS, and the WHO. Recipes are independently written; they are not scraped from blogs. SAVE WHAT WORKS Heart any recipe to save it. Organize favorites into folders ("weekday", "freezer batch", "loves it"). See your recently viewed recipes anytime. HANDY KITCHEN TOOLS A built-in unit converter handles Taiwanese rice cups, tablespoons, teaspoons, millilitres, cups, and weights — no more guessing. BILINGUAL Fully available in Traditional Chinese and English. Switch anytime; recipe content switches too. PRIVATE BY DEFAULT No account. No sign-up. No ads. No tracking. No analytics. Your baby's profile and your favorites never leave your device. --- IMPORTANT: Baby Food is a reference cookbook, not medical advice. Adjust your baby's diet to their individual development, allergies, and health. Consult a pediatrician or dietitian before introducing new foods. Honey must not be given to infants under 12 months.

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.
