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.

Budgets lets you allocate your monthly income to various budgets and thus gain insights in what your money is spend on, limit how much money you spend on certain things and to be prepared for larger expenses in the future Monthly income maybe one or more incoming external or internal movements and/or money coming out of a budget. These monies are then spread over the various budgets. Some of these budgets can also be monthly, such as rent, insurance or utilities expenses, or can be once or few times per year, or even every few years only. Non monhtly expensed will also require a monthly deposit in order for the money to be available without any disruption to the financial position. A special Allowance budget can be designated for day to day expenditures which are not of a fixed nature and could profit from moneys not spend on other expenses. All monthly, quarterly or half-yearly incomes, expenditures and budgetting can be entered in Recurring Movements. These movements will be automatically inserted in the correct intervals, a number of days ahead of their due date as specified.

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.
