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
Organize your own recipes, build meal plans and share them with household members using a clean, simple app. Add meals yourself and schedule them for any week. Invite family or roommates and everyone can contribute, view the plan and help build the grocery list – the app automatically turns your scheduled meals into a grocery checklist so you spend less time writing lists. Members can even nominate dishes and vote on what to make next. Snap or upload photos of dishes and tag meals however you like (protein, vegetable, dietary preference, etc.). Designed for busy homes, Kaizen Kitchen takes the guesswork out of “what’s for dinner?” and helps reduce food waste with shared planning. Get started by creating an account, adding meals, and inviting your household. Use the profile menu to manage settings or delete your account anytime.

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.
