Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Designed for multi-touch! No more pecking one pixel at a time – fluidly paint pixel art using several touches at once. Tap a tile to zoom in and work with precision. The companion mini-view shows what it looks like at normal size. Drag any tile to instantly copy it to another tile. Great for making similar versions of a sprite. Press and hold with one touch to fill an area. Press and hold with two touches to lift and copy a rectangular region. Customize a palette of up to an incredible 16 colors! Expand your canvas to a staggering 512 by 512 pixels! Press and hold any color in the palette to adjust it to any of a mind-blowing 4,096 possible values! Experiment with color sets by pressing and holding the palette to replace an entire row of colors. Save your work in iCloud and resume it from another device. Export your art as a pixel-perfect PNG image.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
