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

See music from a new perspective with Rhythm Necklace, the playful yet powerful tool for improvisation and composition. Tap, flip and rotate simple shapes to explore complex polyrhythms. Gestural control of beat distribution algorithms allows for the step-by-step generation of rhythmic shapes. Layer intricate beats in a matter of minutes, then save them for later or export to MIDI. - Build rhythms on up to four necklaces. - Adjust the length of each individual cycle to quickly create complex rhythmic ratios - Use a collection of rhythm building algorithms and geometric transformations to create and morph your rhythm. -Tap your tempo, use a slider for transitions, or manually type the global speed of your song - Choose from a variety of pitched sounds and percussive sample sets. - Quickly modulate between notes in four musical modes (pentatonic, major, minor, chromatic) and five octaves. - Customize the attack and panning of sounds to suit your composition - Save your sessions and export them as midi. - E-mail copies of midi sessions to yourself. These can be opened and edited on most DAWs. - Midi in/out allows you to fully customize your sounds and record your compositions in real time within an external DAW environment. The term ‘rhythm necklace’ is used in music to refer to circular representations of repeating patterns. By thinking about rhythms as shapes rather than a linear timeline, it’s easier to see geometric properties that make them enjoyable, such as evenness and symmetry. Often, even subtle changes to the visual interface can completely transform how a rhythm sounds. Rhythm Necklace is a tool for both advanced and novice musicians alike, as well as anyone who wants to think about rhythms in a new way.

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.
