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 app Shakeitoff with the TRE® exercises can help you resolve your traumata, overcome anxiety, compulsions and panic, and find calm, confidence and serenity serenity. This app helps you trigger neurogenic tremors, a self-healing reflex of our body, an innate ability to release tension and stress reactions. The word "neurogenic" means that it is a physical reaction that you cannot consciously induce or control. Neurogenic tremors release the tension your body has built up from strong internal feelings and external influences. You become calmer, serener and more relaxed. Neurogenic tremors make you more resilient, more resistant to stress, and also gradually make pain disappear. Ancient healing traditions have used the power of involuntary trembling for thousands of years. NeuroZittern offers the following functionalities: Knowledge - Background information about TRE. How to - Basic instructions on how to perform the exercises. Exercises - Detailed description of the 7 exercises with additional video instructions. The 7 TRE exercises trigger neurogenic tremor. Poem by the Inuit shaman Uvavnuk: The great sea has set me in motion, Set me me in motion, Moving me as the weed moves in a river. The arch of sky and mightiness of storms Have moved the spirit within me, Till I am carried away Trembling with joy.”

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.
