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
Are you ready to perform at your best? Readiness can assess how prepared are you to train and compete with a very short, evidence-based wellness questionnaire right from your iPhone, iPad o Mac! Designed by the sports scientist behind popular apps like My Jump 2 or My Lift, Readiness can help coaches and athletes in their decision making process by monitoring daily readiness in a simple way. It creates a Readiness score in a scale of 1 to 9 based on perceived sleep quality, muscle soreness, fatigue and stress. Then, it compares daily scores with the average of the previous two months using a very intuitive traffic light system: green is ok, orange is moderate fatigue and red is high fatigue. Also, Readiness has great features that can help coaches and athletes to improve their training: -Create as many teams as athletes as you want with no restrictions -Register as many tests per athletes as you want -Export the whole data in a CSV file to Excel or other popular apps -Check your evolution with intuitive graphs

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.
