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

Welcome to Expedition White Shark, the world’s first app designed to track adult white sharks in real time! To make this possible, scientists at the Marine Conservation Science Institute (MCSI) attached custom satellite tags to the dorsal fin of adult Great White Sharks, allowing us to follow their movements from Satellites orbiting the earth. Expedition White Shark allows you to receive near real time Great White Shark tracking data at the same time as the research scientists. Positions for the tagged sharks can only be calculated when a shark is at the surface with its dorsal fin out of the water for several minutes; since sharks are not always finning we receive intermittent position data from our sharks, but each signal beamed to us form space adds to our growing knowledge of the life history of this species. Since you are getting our data in near real time you will notice that the satellites sometimes make mistakes, placing the shark far from its actual location; we correct these errors later, when we analyze the data. The MCSI satellite tagging of Great White Sharks has led to many important new findings regarding white shark biology, and each new day brings promise of a new discovery that you can make with us! Use the shark filter to select a specific shark or see the last position for all sharks of a specific species, or select current to see shark positions within the last 30 days. If current is selected the last position for a shark that appears on the map as a dorsal fin , while sharks with historical location data on today’s date in previous years are marked with dot. This allows users to look for patterns of where sharks may be found during that time of year. Keep up with the latest research insights posted by Dr. Michael Domeier and Nicole Nasby-Lucas, by following us on Facebook www.facebook.com/MarineCSI and Instagram @marinecsiorg.

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.
