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
GMonitor is a simple Field Monitor application for Wifi capable Lumix cameras like the Lumix G6,7,81,85, GX8, GX80/85,GH4/5. Simply enable wifi on the camera and connect the app with camera. After connection you can view the live view fullscreen on your iPhone or iPad. Caution for GH3 users - as reported by some users there is no live view during recording on some GH3 models. This is a bug of the camera. It seems that not all GH3 models exhibit this bug. You have the option for different display modes including anamorphic desqueeze. Also it is possible to display 1:2.35 crop marks. If Peaking or Zebra is enabled on the camera you can also view it on your iPhone/iPad As the Lumix cameras only support 640*480 resolution over the Wifi connection the image is scaled on your device.

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.
