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
Mola is a stencil tiling tool for tattoo artists. Whether you're printing a full sleeve, back piece, or any design too big to fit on a single sheet of paper, Mola splits your design across multiple A4 pages so you can print stencils at any size — using the printer you already have. No thermal transfer printer required. No proprietary hardware. No subscriptions. HOW IT WORKS 1. Upload your design (PNG or JPG) 2. Enter the size you want in centimeters — or let Mola read the DPI automatically 3. Optionally crop out whitespace 4. Preview the tiled layout 5. Export as PDF, ready to print Each page includes crop marks and page labels (R1 C1, R1 C2, etc.) so aligning your printed sheets is straightforward. DESIGNED FOR TATTOO ARTISTS Mola was built with input from a working tattoo artist and tested in real studio environments. It fits into your workflow whether you're using Procreate on iPad, importing scans, or working from any digital source. FEATURES - Automatic DPI detection from Procreate and standard image exports - Precise cm-based sizing with real-time page count preview - Free-form crop tool with pointer-perfect precision - Adjustable page margins (default 15mm, adjust as needed) - Multi-page A4 PDF export with crop marks - PNG and JPG export options - Works offline — your designs stay on your device - No accounts, no logins, no cloud uploads PRIVACY Mola processes everything 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.

BUILD KIT DIFFICULTY
Intermediate
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.
