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 venerable U.S. weather app Wx, named a Mac Gem by Macworld magazine, is now available for iPhone! Wx displays current conditions, forecasts, alerts, and radar for U.S. locations using high fidelity XML data from the U.S. National Weather Service. The app is designed for two specific types of customers: serious weather watchers who want detailed information and facts with no fuss, and casual users who want a fast, clean, and functional weather app that has low memory overhead and low CPU/battery usage. Wx lets you choose your location on an embedded map, and uses that to setup custom forecasts based on the latitude and longitude of the location. Forecasts include a 7-day summary "point" forecast, and a 7-day “pro” forecast that graphs temperature (actual and apparent), dew point, relative humidity, cloud cover, wind speed, wind direction, gust speed, 12-hour probability of precipitation, 6-hour liquid precipitation amount, and 6-hour snow amount. These forecasts are about as good as it gets if you need to plan work, sports, hobbies, and outdoor activities based on upcoming weather. With their high spatial resolution, the point and pro forecasts are especially useful in coastal and mountainous regions, where typical zone forecasts can be inaccurate. Wx also lets you receive current conditions data from nearby NWS observation sites (over 1700 available in the U.S. and its territories), get radar data from nearby NEXRAD radar sites, and receive warnings from nearby city- and county-based alert zones. Wx lets you bookmark and setup weather maps for quick reference. Choose from some default NWS maps and images, or provide the URL for any map of your choice and load it right in the app! If you have preferred weather providers, you can load your favorite maps and images right in Wx and keep them handy. Wx is crafted with attention to detail by a professional software developer with 29 years of experience, 15 years focused on developing weather software for OS X and 12 years writing apps for iOS devices. Wx has multiple levels of redundancy to handle severe weather events that can strain NWS servers, and even offers network settings for both Wi-Fi and cellular operation so that you can fine tune the app’s performance and bandwidth needs. Wx is also available for the iPad and OS X.

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.
