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.

Shift Worker is designed for people who need a quick and easy way to enter and view their shifts. A traditional calendar is not always ideal for shift workers. Sometimes it's not easy to see your upcoming shift schedule very clearly, especially if your shifts don't fall into the traditional working week. Shift Worker solves this problem and turns the frustrating task of entry into a quick and easy experience. Shift Worker allows you to create your own types of shifts by combining visually-attractive icons with letters/numbers so that they can be easily identified at a glance. By including a range of icons (such as suns and stars for day and night shifts) in a variety of colors, any combination is possible for all types of shifts. Entering shifts can be done quickly by simply selecting a type of shift and tapping on each date it occurs. An entire month of shifts could be entered in seconds, an entire year in a few minutes! In addition, Shift Worker allows you create multiple calendars to see friends and family shifts! You can send your shifts to others so they can also see your shifts at a glance as an image or in their copy of Shift Worker. To make things even simpler, you can even save your shifts to your iPhone/iPod's background so that referring to your upcoming shift schedule is as simple as picking up your iPhone/iPod. Shift Worker also includes the ability to create colored personalized notes for each date. Notes can be used anytime additional information needs to be added to a date. FEATURES: - Create a virtually unlimited amount of shift types - Enter shifts on the calendar months in advance in seconds - Add your rotation and automatically fill the calendar in a few simple steps - Show friends and family shifts using multiple calendars - View the calendar in timeline format to see your shift flow at a glance - Create colored personalized notes for any date on the calendar - Include week of year or week 1/2 alternating pattern on calendar - Jump to any month by using the "Goto" button - Save a month's worth of shifts to your background - Share your shifts to others via email, MMS, Facebook or Twitter - Import other Shift Worker shifts and view them all within the one app - No in-app purchases! - No ads!

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.
