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

This app is designed after a very popular exercise taught by a world famous music education guru in the Boston area. Many generations of musicians from all over the world traveled to Boston and waited in a two-year waiting list to access this information and now it is available to everyone at a low price. It will help anybody significantly improve their aural skills. From beginners to professionals, this is a great workout for your ears. Hear from 1 to 11 notes at the time relative to any major key, diatonically or chromatically. Select whether you want to see notes by name, degrees or movable do. It's fun, it includes flexible options, it's very easy to use and extremely effective. Now you can train and open up your ears anytime, anywhere! If you stick to it it will build up your perceptions all the way to near perfect pitch. Politonus keeps track of your progress and tells you when you've reached a master level in the current settings so you can confidently move on to a more complex ear training workout (Both note streak and accuracy circles will turn green). Politonus includes a coach with a powerful algorithm for relative and/or perfect pitch that acts as an ear training tutor. It presents progressive exercises and allows you to step up to a harder level when you are ready. With Politonus you'll have a great ear training teacher anywhere! You will not regret this purchase.

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.
