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
Turn any compatible device into a HomeKit security camera. Pylo turns a spare device into a fully functional HomeKit bridge — no hub, no cloud account, no subscription. Just open the app, scan the pairing code in Apple Home, and your old device becomes a security camera with live streaming, motion detection, and flashlight control. Features: • Live camera streaming in the Home app with two-way audio • Motion detection using the accelerometer and camera • HomeKit Secure Video recording support • Ambient light sensor • Flashlight control as a HomeKit lightbulb • Choose front or back camera, adjust video quality • Screen saver mode for always-on use • Add or remove accessories on the fly Designed for privacy: • 100% local — video never leaves your network • No accounts, no cloud, no data collection • All communication encrypted end-to-end • Works entirely over your local Wi-Fi Pylo is ideal for repurposing an old iPhone or iPad as a baby monitor, pet cam, front door camera, or general home security camera — all integrated natively with Apple Home. Note that in order for Pylo's features to work, it must remain in the foreground and the device must remain unlocked. If you use other apps or lock the device while Pylo is running, it will stop communicating with the Home app.

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.
