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

I created this app to help get my baby daughter to sleep. I was looking for an iPad app that would serve as a simple night light that would dim over a period of time. I couldn't find one, so I wrote Fade Out Night Light. Fade Out Night Light is a simple app with a single purpose - to gradually dim to black, then allow the iOS device to lock. The app consists of: - A single button to choose a background: plain screen, water effect, or expanding circles - 3 sliders: Red Amount, Fade Time, and Time Remaining - A Start/Stop button The first slider allows you to add a red tint to the white screen. This cuts the blue light and makes it easier to sleep. The second slider is where you set the fade out time, from 1-60 mins. The third slider shows how much time is remaining and will gradually move to zero after you hit start. When you hit start, the controls will dim and only the Time Remaining slider will be visible. This allows you to quickly turn up the brightness if you need to see, or if you want to give more time until it's dark. While the timer is running, the device will be prevented from sleeping. Once the timer is finished and the screen is dark, the device will be allowed to auto-lock to save battery.

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.
