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

Global Surf Industries and Swellinfo.com have teamed up to bring you - Swell Info, the complete surf report and surf forecast tool for your iPhone. Swell Info has full seven day detailed surf forecasts, current weather, tides, and buoy data all in a sleek, super easy to use interface. This is an app you will use for today's surf session, and planning your surfing week. Swell Info currently offers forecasts for the entire US (including Hawaii), Mexico, Central America, and Puerto Rico. New locations will be added in time. All locations available on the app are available free on the Swellinfo.com web site. Please check the web site to see a lit of all our forecast locations. Launching Swell Info brings you to the main forecast screen providing a summary forecast for the morning and afternoon for each of the 7 days, conveniently color coded using green (clean), blue (fair), and red (choppy). You can swipe back and forth between your 5 favorite locations, and when you want the details, you can click on each day to get the detailed text surf forecast, tides, and hourly wind and swell data. The Swell Info app, also includes current wind, weather, tides, and buoy data, updated hourly at the top of each main forecast screen. This is the crucial information that notifies you on what the surfing conditions are right now - what the tide is doing, whether the sea breeze has kicked in, or if the new swell has started to show on the nearest buoy station.

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.
