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
Give a presentation wirelessly from your iPhone or iPod Touch in 3 steps: STEP 1: Launch Air Projector. STEP 2: Open the displayed URL in the web browser. STEP 3: Pick a photo or PDF page and it appears remotely. WIRELESS PRESENTATIONS, FROM YOUR PHONE Air Projector projects PDF slide decks, documents, and photos wirelessly from your iPhone or iPod Touch to one or more web browsers connected on the same local network. No additional client software or special hardware is required. You don't even need a projector for small meetings: Have your colleagues open the URL on their own phones or computers. Always be ready with your key presentations in your pocket. Air Projector is perfect for: * Classrooms * Boardrooms * On-the-go presentations PROJECT PDF FILES This works great with exported PDFs from PowerPoint or Keynote.

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.

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.
