Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
EKG Academy is a quick reference and interactive study guide for electrocardiogram (EKG or ECG) strips. Over 100 quiz questions are provided, covering both EKG medical background material as well as a "Name That Strip" section to see if you can identify the strip you see. It's a fun way to review what you know and keep your skills sharp. In addition to the interactive quizzes, you can browse over 75 strips which come with a brief discussion pointing out the key characteristics and possible causes. Along with the measurement guide diagram and 12 lead placement diagram, you just may learn something new (or remember something old)! As a special bonus, there is a CPR section covering the latest 2011 AHA guidelines, written by a certified CPR instructor. This includes a quick reference, an interactive quiz, and even a metronome to show you the proper speed of compressions! Peakview Software is a leading provider of emergency response software, and we are committed to improving and updating our products. Just email your requests. This is a universal app so one purchase runs great on your iPhone/iPod Touch as well as your iPad.

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.

BUILD KIT DIFFICULTY
Intermediate
From the Build Kit assessment.
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.
