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
Embark on a cosmic journey with our app as we explore the intricacies of the visible and invisible Universe, unraveling the mysteries of the ether. The very fabric of our existence is shaped by the ethereal vibrations, manifested in five primary and eventually seven fundamental frequencies known as Tatwas. At the heart of our cosmic ballet is the majestic Sun, the king star, bestowing life upon Earth and its celestial companions. Witness the Sun's energy journey through the vast expanse of the ether, akin to the dance of lightning in a storm. Along this ethereal path, substances accumulate, altering the energy's course until it reaches us. In our app, delve into the mesmerizing world where the length of a ray's zig-zag is a direct reflection of its potential. The fixed nature of the Sun's rays allows us to pinpoint precise moments in time, as each Tatwa vibrates in its main tone for a designated 24 minutes every two hours. Join us on a celestial exploration, where the interplay of vibrations and cosmic forces unveils the secrets of our Universe. Gain a profound understanding of the cosmic rhythms that govern our existence and experience the harmony of the cosmos like never before.

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.
