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 new asset management app developed by a Certified Public Accountant. You can easily create your own personal balance sheet. There is no need to enter small details like in a traditional household account book. Just record major expenses and investments roughly. ・Bought a house ・Replaced your car ・Purchased investment trusts ・Education or self-investment costs ・Loan or credit payments Simply by recording these major life "expenses and investments," you can instantly see what you have spent your money on and what you have built so far. A balance sheet that shows it all at a glance will be created. This app is not just a recording tool. It will help you rethink how you use your money. ■■■■ Main Features ■■■■ ・Automatically creates B/S (Balance Sheet) and P/L (Profit and Loss Statement) ・Customize your own account titles and sub-accounts ・Register journal templates to simplify data entry ・Easily search for past expenses and investments by conditions ・Export CSV to link with PC or other accounting software ■■■■ Other Features ■■■■ ・Simple and smooth interface ・Can also be used as a household budget app (with P/L function) ・Gain accounting and management sense simply by using it ・Great as a learning tool for bookkeeping or accounting ・Useful for preparing tax returns ■■■■ Developer’s Thoughts ■■■■ Ordinary household books show “how much you spent this month,” right? But this app is a little different. This app focuses on the question: “What do you own now? How much has it grown?” — a stock-based perspective. By recording each expense while asking “Does this become an asset?”, your own personalized balance sheet will be completed. You will naturally start to see what’s truly valuable spending and how to build wealth. Of course, for those who prefer a traditional household accounting style, it can also create a P/L (Profit and Loss Statement). What is “wealth” for you? Find out with this app.

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.
