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
Designed by a photographer, for photographers. Built with one clear goal: precise spot metering for photographers who want full control over exposure. mySpotMeter turns your iPhone into a dedicated spot meter with selectable 1°, 2° and 4° measuring angles. Whether you shoot film or digital, you can isolate specific areas, evaluate contrast and place your exposure with confidence. Key Features • Selectable 1°, 2° and 4° spot metering angles • Dedicated readings for shadows, highlights and middle gray • Aperture or shutter speed priority • Average readings mode • Store and compare measurements directly on the exposure scale • Clear EV difference between your target and the current reading • Instant aperture calculation based on the selected ISO and shutter speed • Shutter speed range from 240 seconds to 1/8000s • Aperture range from f/1.0 to f/128 • ISO range from 3 to 409.6K • Exposure settings in 1/3 or 1/2-stop increments • Measure using the on-screen control or the iPhone volume buttons • Automatic calibration and precise manual EV adjustment • Filter factor correction up to FF1000 Built for Deliberate Exposure Instead of averaging the entire scene, mySpotMeter lets you measure only the area that matters. Compare shadows and highlights, understand the available contrast and decide exactly where to place your exposure before pressing the shutter.

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.
