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

This is an AUv3 compatible effect plugin which is intended for use inside your favourite DAW such as Cubasis, Auria, Meteor, AUM or GarageBand etc. The Vocal Soloist plugin was specifically designed for adding harmonies and basic auto tuning frunctionality to recorded vocal lines. It is specifically tuned to the frequency range of the human voice and tracks the incoming vocal frequency attempting to tune to the desired musical key and mode of your song. This effect works in real-time and is able to track a monophonic input creating a convincing harmony at either a specified number of semitones or a key/scale offset. The auto tune allows you to snap to the nearest semitone in chromatic mode, or scale note when a key / mode is selected. We have also included our very popular vocal doubler and reverb to give added presence and thickness to your vocal lines. The effect includes MIDI control over pitch. If your DAW (such as AUM) supports sending key on/off information to the effect you can directly control the pitch of the harmony. For those DAW's that do not support this you are able to route MIDI from one instance of Vocal Soloist to another instance listening on the same bus. The effect also includes controls for defining your own scales as well as controlling vibrato. Features: ○ Real-time processing. ○ Allows fixed 3rd, 5th, 7th harmonies etc. ○ Basic Auto-tune (snap to nearest note). ○ Specify a musical key and mode. ○ Ability to snap harmonies to selected key. ○ Built in Vocal Doubler. ○ Built in Reverb Effect. ○ MIDI control for harmony note. ○ Built in MIDI routing. Note: You can now load this plugin using the internal name 'SoloistFX' or 'HarmonizerFX'.

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.
