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

Kebarp is your go-to arpeggiator for quick and easy pattern creation. Its customizable and responsive grid allows you to craft arpeggio patterns effortlessly. Simply connect a MIDI keyboard or sequencer to Kebarp as a source, and route its MIDI output to an audio app. It will arpeggiate the note you are playing according to the pattern you've drawn on the grid. You can fine-tune the arpeggiator's settings, including minimum and maximum octave reach, step count, gate, velocity, and swing, directly from the control grid. Easily select a scale from the control strip and start creating arp patterns by dragging your finger around the grid. To remove a note, simply tap on it. All notes are locked within the chosen scale, with numbers on the grid representing notes relative to the root note. For instance, 1 represents the original note, +2 is the note after, -2 is the note before, and so on. The retrigger option in the settings menu resets the sequencer with each new note played. Activate pattern chaining to automatically advance to the next pattern once the current one finishes playing. Includes Kebarp and Keboard AUv3 MIDI plugins. The standalone version of Kebarp supports Ableton Link. Please note that Kebarp is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.

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.
