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

Open the toy chest and you get two puzzle benches that play nothing alike. Here is exactly how each one goes. Wind-Up Dash, step by step: 1) A clockwork tin toy sits on the playroom floor and a toybox waits across the room. 2) Tap Turn to spin the toy so it faces the way you want it to travel. Turning is free. 3) Tap Wind Up to spend one wind from the spring. The toy dashes forward until a wall stops it. 4) Yellow arrows spin it mid-run, red patches drain an extra wind, blue pads hand one back. 5) Land on the toybox before the winds run out. Sixty levels, and the later floors leave no winds to spare. Pop Rows, step by step: 1) A sheet of bubble wrap appears with a number beside every row and column. 2) Press any blister to pop it, and its neighbours flip too. 3) Keep pressing until each row and column holds exactly the number shown. 4) A counter turns green the moment that line matches. Undo whenever a press goes wrong. 5) Seventy-five sheets grow wider, add diagonal pops, and lock some blisters solid. Both benches track your levels, stars and badges, and everything works offline.

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.
