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

World-class jazz rhythm section play-along in state-of-the-art app setting! Featuring Peter Erskine on drums, Alan Pasqua on piano, and Darek Oles on bass, this app has been designed and created for use by all musicians who are interested in perfecting their jazz skills and artistry. The heart of jazz is being able to play the blues and “standards” in common keys and at different tempos. With a century’s worth of professional and pedagogical experiences between the three musicians, these tracks target and explore an essential variety of requisite jazz modes and styles that we have found to be of the most use. Utilizing the built-in mixer, you can create your own combo: full rhythm section (trio), music-minus-piano, music-minus-bass, music-minus-drums, or solo tracks of drums-only, bass-only or piano-only. There are click-track and count-off options as well. PDF lead sheets are included in the keys of C, Bb and Eb. These charts can be printed or emailed from the app. In the case of some well-known standards, we have adhered to the form and chord changes of the songs unless otherwise noted. The melodies to these tunes can easily be found on-line or in a RealBook, etc. There are also some classic tune forms from the post-bop era, making this collection up-to-date and relevant. We suggest that you listen to the full trio mixes at least once in order to hear how the band is playing this music — unless, of course, you wish to fully embrace the jazz spirit and experience the performances in real time: hearing and playing the music for the first time just like in a true jazz setting. In any event, you now have a world-class rhythm section at your fingertips. As the beboppers say: “Straight ahead and strive for tone...” There’s no better way to play better than to play more. Keep on swinging. --Peter Erskine

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.
