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 72 Names of God, based on three verses from the Bible, is one of the oldest and most powerful Kabbalistic tools. Moses used it to split the Red Sea and you can use it as well to turn everyday challenges into miracles. Based on the book by best selling author and co-director of The Kabbalah Centre International, Yehuda Berg, this app resembles a deck of 72 cards. On one side you'll find the 72 Name with illustration and explanation and on the other you'll find a meditation that you can use to tap into the unique qualities of each name. Additional features include: • Rotate to Landscape to see an interactive chart of the 72 Names • Personal 72 Name: we all have one based on our birth date – find yours! • Ecards: send a 72-Names E-Card to a friend when they need a little extra support • Random 72 Name • Table of contents for quickly finding the right name • Learning section

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.
