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

EōN is a new relationship to "recorded" music as we have always known it by immersing the listener in an endless sound (and visual) experience, like an album whose duration would have no fixed limit. EōN produces an infinite music, in constant evolution, abundant in variations, composed by electronic music pioneer Jean-Michel Jarre, accompanied by a constant progression of organic visual elements. Once the EōN app is activated, you will listen and watch a new unlimited music experience constantly unfold, designed to be absolutely unique for each listener, always different each time the app is launched. You can enjoy a different journey everytime, listening as many times and as long as you want, the only limit being your device’s battery! In addition, once downloaded, EōN is fully autonomous requiring no internet connection. Thus it is possible to launch the app anywhere and at any time. JEAN-MICHEL JARRE ABOUT EōN: "-Eon- the name of an ancient Greek God associated with unlimited time and eternity. I named this project EōN as it symbolizes exactly what it is: an infinite musical and visual creation, which offers to everyone a unique experience, which will never happen again: on each device and each activation of the application EōN, you will hear and see an ever-evolving orchestration of music and visuals. EōN is an endless organic work, never repetitive, that will live and grow indefinitely at your fingertip. Like in life, every moment lived in EōN will never happen again. Personally, I truly feel that EōN is probably one of my most exciting creative projects since Oxygene. I always wanted to create a specific music for each listener, able to evolve constantly in terms of rhythms, tones, tempo, melodies and textures. Here it is. EōN is conceived and composed as a different journey for everyone, with no end determined. I had a clear idea of the organic, living visuals I wanted to accompany my music, and I was very lucky to spend some time in Tokyo at Sony Computer Science Laboratories, Inc. (Sony CSL), where I discovered Alexis André and his singular visual world. Sony CSL with Alexis have conceived and developed an algorithm generating an endless flow of ever-evolving graphics, which, like the music, are infinite and never repeatitive. The algorithm and audio engine that orchestrates the music of the EōN app have been engineered by Alexis Zbik & Vianney Apreleff from BLEASS after defining the rules of the system together.

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.
