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

ToneBoosters Equalizer Pro is a top-quality, innovative, professional, dynamic equalizer AUv3 plug-in with an unrivalled workflow, a whopping 600+ filter types and shapes suitable for any EQ task, and a gorgeous, responsive, functional user interface that is a breeze to work with. In addition to all conventional filter types, such as shelving, peaking, bandpass, tilt, low cut and high cut filters, Equalizer Pro features a range of innovative, signal-adaptive filter types, such as the ability to equalise transients, sustaining elements, foreground and background audio, ambiance, and much more. With these novel filters, Equalizer provides unrivalled control to improve your mixes, fix issues, and create a better sounding mix in less time. All filter types have configurable steepness between 6 and 96dB/octave, and can run on complete mixes, individual channels, or mid/side representations of your audio tracks and busses. Equalizer Pro supports both zero-latency as well as linear phase filter types. Equalizer Pro provides an integrated spectrum analyzer and spectrogram, with configurable spectral resolution, time constants, dynamic range. Equalizer Pro also provides EQ learn and match functionality to timbre match between tracks in a fully configurable and editable manner.

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.
