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

"In short, there’s oodles of scope here for sound designers and anyone who makes more experimental styles of music, whether EDM, chill or ambient." -SoundOnSound Unfiltered Audio's Silo is now available on iOS as a Standalone app or AUv3 plugin! Silo combines granular synthesis, audio spatialization, and reverb into a powerful, essential tool for sound designers and musicians everywhere. Silo combines microscopic granulation with macroscopic reverb tails to extract new realms from your existing sounds. Silo's first section, the granulator, breaks the incoming signal to tiny little bits (called "grains") before reconstructing it with massive amounts of control. You can change the speed and pitch of the signal independently and in real-time! These grains are then sent to Silo's unique spatializer, which throws the grains all over the stereo field. The spatializer contains a number of motion algorithms to add trajectory to your grains, such as the orbital "Moons", the shooting "Meteors", or the squirmy "Biological". After using this spatializer, you'll never want to use a traditional auto-panner ever again. Finally, the signal washes through one of Silo's many reverb algorithms, from small, resonant spaces to enormous, booming voids. From "Bokeh" to "Nebula", each mode can be tweaked to frame your sound perfectly. As an AUv3 plugin, Silo has been tested to work perfectly with Garageband, Drambo, AUM, Cubasis, Beatmaker, Nanostudio, apeMatrix, Loopy Pro, and more! Additionally, with its clear layout and smart resizing, Silo can be used on tablets and phones with ease.

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.
