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
Build the ultimate cat army through tactical breeding and send them into deep, challenging turn-based adventures. Draft abilities, collect items, and manipulate genetics across generations in this roguelike tactics game from the creators of The Binding of Isaac and The End is Nigh. Roguelite progression: never experience the same game twice. Choices at every turn. Money! Items!! And genes!! All matters. From Simple to Infinitely Complex: Mewgenics welcomes you in and then reveals more and more layers over time. Early runs teach the basics, but soon you'll be optimizing breeding chains, discovering unexpected ability combos, and making agonizing strategic choices about whether to keep a cute kitten or give it to one of the many NPCs to upgrade your house. Mewgenics offers you a path to tactical mastery while embracing chaotic emergent gameplay. Build, experiment, adapt! There’s always a new way to experiment with (and break) the game.

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.
