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.

TimeScroller is a multi time zone clock and meeting planner, and allows you to very quickly find a suitable time for an overseas phone call or conference. Initially, the current times for your chosen cities are shown, with color coded icons quickly showing if now is a good time to call. If not, a drag on the "TimeScroller" button will rapidly advance the times to find a more suitable time later in the day. Alternatively, select the cities you wish to communicate between, then tap the "Suggest Time" button for TimeScroller to automatically suggest a time. The display will also update showing just those cities, making the choice of a time even easier. Then once you've chosen a time, a tap on a button create a reminder, a calendar event, or automatically draft an email for you including the times for the proposed call. FEATURES * Visually simple, compact display * Takes into account daylight saving rules where applicable * Configurable to show different colors for different times of the day - for example "green" for normal office hours, "amber" for the evening, etc * Suggest time feature * TimeScroller does not require an internet connection * Built in database includes 20,000+ cities * Information page for city includes the date and time of next daylight savings change as well as sunrise and sunset times

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.
