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

Decisions don’t have to feel heavy. Decision Coin helps you break out of overthinking by flipping a coin - and then paying attention to how you feel about the result. Instead of telling you what to do, Decision Coin gives you a moment of clarity. Often, your reaction reveals more than the outcome itself. How it works: • Enter two options • Flip the coin • Pause and notice your reaction • Let that insight guide your choice Why people use Decision Coin: • To reduce overthinking • To notice gut reactions • To make everyday decisions feel easier • To create a calm pause before choosing Decision Coin is intentionally simple and respectful. No ads. No accounts. No tracking. No subscriptions. Just a small, thoughtful tool for moments when deciding feels hard. One decision at a time.

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.
