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

After many years of researching sensor data for lots of different types of paranormal apps, I have concluded that the best way for Spirits to manipulate a device (or the device sensors) is by keeping it simple and universal across the whole world. The Spirit Music Box works similar to the world famous Para4ce device, but this uses a lot more sensors and is more complex! If any of the sensors pick up a change then the Music Box will start playing an old eerie music box song. Simply place the device in any area, click the "Calibrate" button then move away from the device. If you move the device after it has been calibrated you will need to recalibrate, simply click the "Back" button, move the device to a new area, then click "Calibrate" again. The sensors used are: Magnetometer - This senses Magnetic and Electromagnet fields around the device Accelerometer - This senses any device movement and the slightest vibrations around the device Barometer - Detects any change in the Ambient Air Pressure around the device Compass - Detects the slightest change in magnetic interference to Magnetic North GyroScope - Detects the slightest movement of the device Orientation - Detects the slightest movement to the position of the device If your device is missing any sensors, the app will still work perfectly well without them. ** Disclaimer ** Use at your own risk, I cannot be held personally responsible for you or any outcome (paranormal or otherwise) from using this app!

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.
