Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Welcome to Talos-II, a world of breathtaking beauty and constant danger. The earliest settlers braved wars and disasters, and through more than 150 years of relentless effort, they carved out a foothold and laid out a new foundation for humanity — the Civilization Band. Yet most of this world remains untamed. Vast wildlands and uninhabited territories stretching toward the horizon still await exploration. Every step forward is shadowed by threats — whether remnants of the past or dangers never before seen. Expansion and exploration, as well as continuity and progression, are the eternal themes throughout the evolution of civilization, and the ultimate pursuit of every life that constitutes it. As the Endministrator of Endfield Industries, you will lead your operators to defend and expand the frontiers of humanity. Your Originium engines rumble in the wildlands while production machinery works around the clock to deploy new AIC Factory production lines. Explore the world of Talos-II and gather various resources. Use the AIC Factory to overcome dangers and work with the operators to build a better homeland for humanity. A new era of change has dawned upon this ancient world. Time to make your choice, Endministrator. ※ The app is free to download, but it offers in-app purchases for certain items (including random items).

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.

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.
