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

Do you have trouble going to sleep? Are you traveling on a plane and need a quick power nap? Does your newborn baby wake up in the middle of the night? There are numerous benefits to using White Noise: • Helps you sleep by blocking distractions • Relaxes and reduces stress • Pacifies fussy and crying babies • Increases focus while enhancing privacy • Soothes headaches and migraines • Masks tinnitus (ringing of the ears) Even when you’re asleep, your brain is constantly scanning and listening for sounds. If it’s too quiet, unwanted noises such as faucet drips or police sirens can interrupt your sleep. White Noise generates sounds over a wide range of frequencies, masking those noise interruptions, so you can not only fall asleep, but stay asleep.

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.
