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
TrackingScan – Smart Barcode Scanner for Inventory & Delivery TrackingScan is designed to simplify package tracking, inventory handling, and warehouse operations with a fast, accurate, and voice-assisted scanning experience. Key Features: • Barcode & QR Code Scanning After scanning, the app determines if a tracking number belongs to USPS, UPS, FedEx, or Amazon (TBA) for faster classification and sorting. • Voice Feedback Automatically announces the number of scanned tracking codes for quick, hands-free confirmation. • In-App Signature with PDF Export Sign directly on the device during receiving or dispatch. Export signed records as PDF files for printing or compliance. • Export Tracking Records Easily export all scanned tracking numbers as structured data for use in warehouse or ERP systems. • Duplicate Scan Alerts Instantly detect duplicate tracking numbers in the current batch or historical records to prevent errors. • History Lookup Search tracking history by time, batch, or tracking number for fast record retrieval. • Flashlight Button in Low Light When scanning in dark environments, a flashlight toggle appears on the scan screen for better visibility. Whether you’re working in a warehouse, managing logistics, or handling last-mile deliveries, TrackingScan keeps your workflow organized, fast, and error-free.

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.
