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

The original Staten Island Ferry App! ***Featured in the Staten Island Advance!*** Never miss the boat again! The SIFerry app uses GPS to detect whether you are in Manhattan or Staten Island and automatically shows you the Staten Island Ferry timetable relevant to your location as well as a countdown timer for the next ferry departure. The SIFerry app gives you the estimated walking, biking, or driving time and distance to the ferry terminal so you can easily figure out when to leave to make the next boat! The SIFerry app will show the timetable and countdown even without internet connection so you can check the ferry schedule on an iPod Touch or in areas without cellular coverage (like the subway). Easily keep track of the countdown and ETA to the nearest terminal using the today widget. The SIFerry app automatically displays the appropriate weekday, weekend, or holiday schedule. Use the sharing feature to let your friends and family know what ferry you are on and what time your boat will dock. Just tap the line in the schedule for the ferry you are taking and select message, mail, or your favorite social network from the menu. The SIFerry app will automatically populate the text of your message for you.

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.
