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
the i ski kids app guides parents and teachers in the best way to teach children how to ski, either in the backyard or on the mountain. the colorful images, animations, and easily understood descriptions teach kids a step-by-step progression that creates a solid foundation for a lifetime of skilled fun. the methodology, using mechanics that are both natural and completely aligned with the alpine world cup technique, is easy to learn and accelerates development way faster than traditional methods. a portion of every $5 app sale will be donated to outreach programs fostering inclusion in the snow sports arena. the i ski kids app also has a companion instructional coloring book called: i ski - kids: learn how and color. while coloring the images, neural networks are created. through visualizing and noticing sensations children will more fully understand and anchor the necessary components to make skiing a snap. you can find the companion coloring book at amazon link or most booksellers.

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.

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.
