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

Sit on the throne as a benevolent (or malevolent) medieval monarch of the modern age and swipe your royal fingers either left or right to impose your will upon the kingdom. Survive the seemingly never-ending gauntlet of requests from your advisors, peasants, allies, and enemies while maintaining balance between the influential factions of your kingdom. But beware; each decision you make might have implications and unfortunate consequences down the road that could put your reign and family’s dynasty at risk! Each year of your reign brings another important – seemingly random – request from your unpredictable kingdom as you strive for balance between the church, the people, the army, and the treasury. Prudent decisions and careful planning make for a long reign but unforeseen motivations, surprise events, and poor luck can take down even the most entrenched monarch. Extend your reign as long as possible, forge alliances, make enemies, and find new ways to die as your dynasty marches along through the ages. Some events will span on centuries, with an intrigue involving burning witches, scientific enlightenment, wicked politics and, maybe, the Devil himself. *iPhone 5 / iPod Touch 6 / iPad Mini / iPad Air or later recommended.

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.
