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
CrewCase keeps your film production gear organized from prep through wrap. See who has what, when it's due back, and what's in maintenance. No more group chat archaeology to find out where the camera package went. GEAR TRACKING Log your inventory and track every item by status: In, Out, Overdue, or In Maintenance. Things stop going missing. CHECK IN / CHECK OUT Assign items to borrowers with a tap. See who has what and when it's due back. QR CODE SCANNING Attach QR codes to your gear and scan for instant lookup. Fast enough for a busy shoot day. KITS Group related items into kits and check out a whole camera package or lighting rig at once, instead of item by item. STATUS DASHBOARD Your home screen shows active loans, overdue items, and anything in maintenance. One place to see it all.

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.
