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
Flameinmind app is designed to receive data from your body signals and to translates them into graphs related to sacred geometry. Flameinmind collects real-time informations on brain and heart activity (Brain data through Muse headband sensors and heart data through Polar chest strap sensor). This app is making a link between body waves coherence and sacred geometry: searching for Phi and octave rations in your Brain waves and heart rate spectra (as Bliss states are closely linked to octave and phi rations in the body waves). Flameinmind also includes binaural sound waves related to sacred geometry (Phi ratios) that can help to achieve bliss state in your body waves. Now version 4.0 including an update allowing to use the latest Muse sensors. This app only provides the ability to receive, display and store hardware data (brain wave sensor and HRV sensors) via Bluetooth, This app is not a medical device, is not intended for medical use, and does not provide diagnostic features. The hardware (HRV sensors and brain sensors) via Bluetooth involved in this application is used only in a jurisdiction that complies with applicable laws and regulations and is not intended as a substitute for medical advice or diagnostic results. Users of the hardware are solely responsible for ensuring compliance with relevant laws, regulations and standards.

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.
