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

chess openings wizard is where tournament players go to work on their openings. the app is based on the bookup program that first came out in 1984. the app has full editing and training power like its brethren apps on macintosh and windows. openings can be moved back and forth to the macintosh, windows, and android versions. chess openings wizard does not play chess, nor does it come with a game collection. it is meant for designing openings for white and defenses for black, and then testing the player's knowledge of the lines by playing mock games. sample ebooks include an opening guide (thousands of named and categorized opening positions accessible through any move order), an eco master framework, and the white and black repertoires of magnus carlsen, fabiano caruana, and robert fischer. it also includes a demo ebook with excerpts from a highly annotated repertoire in the open game. chess openings wizard has a dedicated pocketgm server giving you full speed stockfish analysis. (internet connection required.) the pedigree ribbon shows the results of games in each opening position but uses only games between two super gms. that way you know if the move is trusted by the best players. (and it's important to know if a move has never been played by a super gm when facing another super gm.) this is the same feature found in chess openings wizard professional for macintosh and windows. the short version is: if you are designing an opening with a game database app or with a playing program, you're working too hard. chess openings wizard contains 42 years of refinements, with precisely the tools that a tournament player requires to prepare openings fast.

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.
