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 Miracle Box is an app used for Spirit Communication and ITC Research. You must use this correctly, responsibly and by using it you are doing so at your own risk. To see the full information and Q&A on how to use this app correctly, you can visit: https://huffparanormal.com/2021/05/the-miracle-box-spirit-communication-app-is-here/ The Miracle Box includes methods used by Steve Huff of Huff Paranormal in his Astral Doorway and Miracle Box full size devices. The app has eleven banks, which are all reversed human speech. There are no words, no music, no phrases and nothing programmed in to make you think spirit is speaking with you. This is an advanced yet simple ITC app based on eleven years of research and communication. It will not work for everyone (no app or box does). When using it, you must do so correctly. If you do not have a connection to spirit you will not hear replies come through. Instead, you will hear gibberish, nothing. That is by design. This app is designed to only bring you true responses, if and only if you connect with a spirit when using it. No matter the app or device you use, the connection is the #1 aspect of getting results. Always use this with love, respect, kindness and a clear mind. If you do not hear replies, try again at another time, or a different place. Do not use it if you are angry, depressed, in a negative mood or fearful of it. If you fear this, do not use this app as fear is an energy we put out that can and could attract undesirable spirits. Love is the key here and this is meant for serous ITC researchers and enthusiasts. Just pick a voice, press record, ask a question and move the slider to the right for 1-3 seconds and then slide it back. You will soon hear a voice emerge that will either be answering you (if you connected) or gibberish (if you did not). Even if you do not hear a reply in real time, always check the recording as it could have changed. This is a tool you can grow with. To learn how to build a connection, and see demo videos with this app in action visit the Huff Paranormal YouTube Channel.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
