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.

Gerald is NOT a payday loan, cash loan, personal loan, or app to borrow money. By validating your employment you can access money you’ve already earned. Gerald's advance service comes with no minimum or maximum repayment time frame requirements. (*) Get advances from $40 to $200 with no mandatory minimum or maximum repayment period, and absolutely no interest or APR (0% APR). For more information please see Gerald's terms and use: https://joingerald.com/legal/terms-of-use. EXAMPLE SCENARIO If you are approved for a $100 advance, you’ll be required to use a specific portion of that advance on our e-store (i.e. Cornerstore). Once this threshold has been met, you can then transfer the remaining balance of the advance to your bank account with no fees attached. For example, if you’re provided with a $100 advance, you may need to allocate at least $50 of this advance towards purchases on Cornerstore. After meeting this requirement, the remaining $50 can be transferred to your bank account hassle-free and with no fees. In this case, your repayment amount will be $100. (*) Not all users will qualify. Subject to approval policies.

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.
