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.

Who said budgeting couldn't have a little personality! HOW IT WORKS Add Products - add items to your VEST (wishlist) by pasting a URL, uploading screenshots, taking a picture, or describing the type of item you'd like. The app automatically pulls in the product name, price, and image. Organize Your Wishlist - Create custom categories to sort your items. You can filter, reorder, and prioritize what matters most to you. Track Purchases - When you buy something, mark it as purchased. It moves to a separate "Purchased Items" section with a timestamp, so you have a record of when you bought it. Monthly Receipt - View your purchases organized by month. If you return something, tap it to cross it out — the totals adjust automatically. Shopping Behavior Score - The app tracks patterns like how many items you add vs. remove vs. actually buy, giving you insight into your shopping habits over time. Use this to determine if the time is right to buy something! Save brands - Keep track of your favorite brands, or the cool ones you come across and don't want to forget! On the Vest data page, personalized insights will give you a story about what your loved brands say about you (it's fun)! WHY SHOP WITH VEST Stop Impulse buys - VEST encourages you to pause before you buy. By saving items to your wishlist first, you give yourself time to decide if you really want or need something. See how much you spend on things overtime - The Shopping Behavior Score and data visualizations show you how you shop over time — what you keep, what you remove, and what you actually purchase. This awareness helps you make better decisions. Vest's goal is to help shoppers buy the things they love, while also staying on top of your budget! (I needed this personally!) Become aware of just how much you spend on things, & shopwithvest - it's mindblowing & very eyeopening! #shopwithvest

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.
