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

Some eye conditions can block areas in your vision. One example is Macular Degeneration. You may not be aware of this because the brain fills in blocked areas. But you can miss things, causing a safety hazard or difficulty in activities such as reading. The Macular Trainer app helps you with two things: - See if this might be an issue for you. - Practice skills to find blocked objects faster. Scanning your visual field can help overcome this problem. Scanning moves a hidden object into areas that you see, so you can quickly find it. For example, a stop sign or an object in your walking path may be in a blocked area. Scanning your gaze a bit can make it visible. Each person's strategy is unique and depends on where blocked areas are located. The app is not meant to provide a diagnosis or recommendations. If you suspect this is happening, you should consult an Eye Care Professional (ECP) for such advice. Note that even if the app does not show an issue, you may have blocked areas, and their size and number can change over time. This app places a cross at a random place in your field of vision. If it is not blocked, you quickly find it. But if the cross is blocked, it often takes you longer to find it. The map provides you a map of your field of vision, highlighting areas where it takes longer to find the cross. If you find such regions, it is recommended that you consult your ECP for further advice. At that point, the app may be use to help you to practice finding objects in blocked areas faster. Many of these eye conditions are progressive, so the size and density of the blocked regions will change over time. But continued practice will help you adapt to these changes.

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.
