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.

Info: A clock chime is a melody that plays at set intervals, usually on the hour, to signify the passing of time. These chimes are commonly heard from grandfather clocks, carillons, or bell towers, and different melodies are often tied to specific locations or towers. A striking clock, also called a chiming clock, audibly strikes the hours on a bell or gong. In the typical 12-hour striking system, the clock strikes once at 1:00 AM, twice at 2:00 AM, and continues up to twelve times at 12:00 PM. It then repeats the process from 1:00 PM to 12:00 AM. Note: Ensure notifications are enabled for the chimes to work properly. Notification sound will be disabled if the phone is in Low Power Mode, Do Not Disturb mode, or Sleep mode.

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.
